Harnessing Citizen Science to Support Nature-Based Flood Management: A Case Study of Photo Post Engagement in the Limb Brook Catchment, Sheffield, UK - Melissa M. Lacey; Cedric Andreasen; Jackie Lowe; John McGlinchey; Patrick Sheard; Claire Bithell; Samuel Lilleker; Martin Reed; Roger Nowell; Rachel Schwartz-Narbonne; Rebecca Sharpe (Environmental Management, 2026)
Nature-based solutions (NBS) are increasingly promoted in climate adaptation strategies to mitigate flood risks and enhance ecosystem resilience. However, the monitoring and evaluation of such interventions remain a challenge due to resource limitations. This paper evaluates a citizen science-based monitoring approach in the Limb Brook catchment (Sheffield, UK), where public photo submissions were used to assess the effectiveness of NBS interventions such as leaky dams and attenuation ponds. Over a 26-month period, over 4500 photographs were collected from 15 fixed photo points. The analysis demonstrates high initial engagement, varied spatial interaction across sites, and the potential for real-time detection of intervention failures. We critically examine how public participation in environmental monitoring can support adaptive flood risk management while highlighting barriers related to data infrastructure, privacy regulations, and long-term community involvement. This study underscores the value of integrating citizen science into national and local policy frameworks for environmental governance.

In the field of environmental science, data characteristics often exhibit significant variability, challenging the applicability of classical probability distributions for environmental data modeling. In this paper, we introduced a novel four-parameter distribution called the type II half-logistic exponentiated Kumaraswamy (TIIHLEKw) distribution, derived from the type II half-logistic exponentiated generalized family of distributions and using the Kumaraswamy distribution as the baseline. This distribution exhibits greater flexibility compared to the traditional Kumaraswamy distribution. Importantly, the TIIHLEKw distribution offers symmetrical, right-skewed, left-skewed, unimodal, J-shaped, and reversed J-shaped densities and various hazard functions, including increasing, decreasing, bathtub, and J-shaped forms. These patterns exhibited by the distribution make it particularly useful for modeling environmental datasets. Basic properties of the TIIHLEKw distribution, such as moments, moment generating function, quantile function, hazard function, survival function, Renyi entropy, skewness, kurtosis, and distribution of order statistics, are derived. Unknown parameters of the distribution are estimated using the maximum likelihood approach, and the performance of maximum likelihood estimator is assessed through Monte Carlo simulations. Finally, three applications to real data on measurements of burr (in millimeters), measurements taken from petroleum rock samples in a petroleum reservoir, and Senegal's COVID-19 mortality rates for 31 days, from July 18, 2021, to August 17, 2021, are evaluated to demonstrate the importance of the TIIHLEKw model over other extended versions of the Kumaraswamy models. The empirical findings suggest that the TIIHLEKw model outperforms other extended versions of the Kumaraswamy models in these applications.

Filling the gap between lansfordite and nesquehonite: MgCO3·4H2O, a new magnesium carbonate hydrate - Guntram Jordan; Samuel B. Strohm; Aleksandar Živković; Giacomo Criniti; Kai-Uwe Hess; Melanie Kaliwoda; Elena V. Sturm; Daniel Weidendorfer (Physics and Chemistry of Minerals, 2026)
Formation conditions, transformation mechanisms, and transformation product selection of magnesium carbonate hydrate phases at temperatures near the freezing point of water are poorly understood. In this study, carbonated Mg(OH) 2 suspensions were aerated at T = 0 °C to obtain solutions from which either MgCO 3 ·6H 2 O or lansfordite (MgCO 3 ·5H 2 O) precipitated, with the selected phase depending on the aeration rate. Subsequently, magnesium carbonate hexahydrate was subject to transformation experiments yielding five different products. The product selection depended on the transformation condition. Among the products, a new phase was identified and characterized as a neutral magnesium carbonate hydrate with the chemical composition MgCO 3 ·4H 2 O. Implications of the synthesis route and analytical results suggest that this tetrahydrate phase forms from MgCO 3 ·6H 2 O by the release of two weakly bonded water molecules per formula unit, accompanied by a relaxation of the remaining MgCO 3 ·4H 2 O layers without disrupting the edge-sharing octahedral pairs of the parental structure. Density functional theory calculations confirmed the stability of the proposed crystal structure through the examination of its phonon dynamics and subsequent vibrational analysis. Furthermore, the simulated X-ray powder diffraction pattern is in reasonable agreement with the experimental data when accounting for the high crystalline disorder inevitably introduced by the transformation process.

Sirtuin 1 as an emerging exerkine in the aging process: unveiling its multifaceted biological roles - Patrício Lopes de Araújo Leite; Larissa Alves Maciel; Rita Cristine Barboza Patricio; Geovanna Lopes Carneiro Pereira; Antônio Sérgio de Oliveira Lamounier; Samuel da Silva Aguiar; Caio Victor Sousa; Ivo Vieira de Sousa Neto; Herbert Gustavo Simões (Biogerontology, 2026)
Sirtuin 1 (SIRT1) was initially identified as an enzyme that deacetylates histones and suppresses gene activity. Since then, its roles have expanded considerably, and it is now recognized as a multifunctional protein conserved across various organisms. Despite increasing interest, it remains essential to clarify how exercise-induced changes in SIRT1 counteract multiple hallmarks of aging, as well as the full scope of SIRT1’s impact on different physiological systems. This review highlights recent findings on the short- and long-term effects of exercise on SIRT1 signaling in both rodents and humans during aging. We explore the molecular pathways activated in various tissues, providing insight into the specific biological functions of SIRT1 within aging cells. Optimal levels of SIRT1 help maintain homeostasis and a biochemical environment conducive to healthspan, influencing biological processes such as mitochondrial dynamics, metabolic pathways, tissue remodeling, autophagy, inflammatory responses, and redox balance. This indicates that SIRT1, a pleiotropic molecule, orchestrates multiple responses throughout aging. SIRT1 may act as a dynamic sensor for exercise benefits and protect against aging by maintaining genomic integrity. Different exercise protocols (acute and chronic) and modalities (aerobic, resistance, and combined training) can increase mRNA levels, activity, or protein levels of SIRT1 in various vital organs (adipose tissue, hippocampus, heart, liver, bone, and skeletal muscle) of aged animals and older adults, promoting health. Taken together, these observations support the notion that SIRT1 functions as a potential exerkine, and understanding its role in exercise-induced adaptations offers new insights into non-pharmacological strategies to enhance longevity.

The resistance of lemon myrtle (Backhousia citriodora) to myrtle rust (Austropuccinia psidii) - Emily Kathryn Lancaster; Geoffrey Samuel Pegg; R. Andrew Hayes; André Drenth; David John Lee (Australasian Plant Pathology, 2026)
Lemon myrtle ( Backhousia citriodora , F. Muell.) is a native Australian myrtaceous species, highly valued for its unique, citral-rich essential oil. The development and success of this Australian industry has been in jeopardy since the detection of myrtle rust ( Austropuccinia psidii ) in Australia (April 2010). Since the initial invasion, it has spread across the major lemon myrtle growing regions in New South Wales and Queensland. The main commercial clones are highly susceptible to infection, with plantations experiencing up to 70% production losses. To identify resistance to A. psidii for industry use, disease assessments were conducted on germplasm originating from 13 Queensland provenances, established in two clonal field trials. Newly collected germplasm from the Ubobo provenance was also screened under controlled conditions. Infection caused symptoms ranging from small, restricted sori on a low percentage of leaves, to infection on up to 100% of leaves, with distorted shoots and severe dieback on infected stems. No fully resistant germplasm was identified, but significant differences in observed disease offer opportunities to select more resistant clones than those currently relied on by the industry. Germplasm from Eumundi, Noosa and Woondum (southern Queensland), and Silver Valley (northern Queensland), showed superior resistance to A. psidii across assessments and trial sites. Substantial variation in plant growth traits of importance to commercial production (e.g. canopy structure and foliage density) was observed among the provenances, families, and clones evaluated across the trials, suggesting the need to consider plant growth, biomass yield and essential oil properties when selecting industry-suitable germplasm. Implementing a breeding or hybridisation program should be a priority for the industry.

Impact of perfluorooctanesulfonic acid (PFOS) on phytoplankton community and physiological responses - Suleiman Dauda; Yillek Simon Gotan; Sadiya Awala Samuel; Adriana Sturion Lorenzi; Zainab Abdullahi Ibrahim; Dora Nguemo Iortsuun; Mathias Ahii Chia (Aquatic Ecology, 2026)
Perfluorooctanesulfonic acid (PFOS), a persistent and bioaccumulative substance, has emerged as a major environmental contaminant of global concern. PFOS, widely used in industry and consumer products, is common in aquatic ecosystems and may harm primary producers like phytoplankton, though its effects on their community structure and physiology remain unclear. Here, we investigated the impact of PFOS on freshwater physicochemical parameters, phytoplankton community dynamics, biochemical composition, and oxidative stress responses in a mesocosm experiment over a 28-day period. The water quality indicators generally were unaltered by PFOS exposure, but phosphate levels decreased initially in the control. Phytoplankton biomass (cell density) decreased at 10 µg L −1 and 10 mg L −1 PFOS exposures. Phytoplankton species richness, Shannon, and Simpson diversity indices declined at 10 mg L −1 , with communities at this concentration becoming distinctly different from the control and lower PFOS treatments by day 28. This shift in community structure was primarily driven by taxa such as Chlorogonium sp. and Microcystis aeruginosa , which contributed strongly to the observed compositional dissimilarity. Proteins content in the phytoplankton increased under PFOS exposure, peaking on day 21. In contrast, carbohydrate and lipid contents were reduced under PFOS relative to the control. PFOS exposure elevated glutathione-S-transferase activity, malondialdehyde, and hydrogen peroxide levels, whereas peroxidase activity was reduced. The phytoplankton biomass and lipids were positively associated, while oxidative stress markers were closely linked with high PFOS concentrations. Overall, these results highlight that PFOS exposure suppressed phytoplankton biomass, altered their community composition, and induced oxidative stress and metabolic shift at higher concentrations, highlighting its potential ecological risk in freshwater systems.

Supplemental Application of Potassium Acetate Increased Yield of Mesa Russet Potatoes in Sandy Loam Soil with High Potassium Levels - Salah M. Abdelsalam; Samuel YC Essah; Jessica G. Davis (American Journal of Potato Research, 2026)
Potato responses to potassium (K) fertilizer have sometimes been reported in high K soils. This study was designed to investigate the effects of supplemental application of K acetate, a new potassium fertilizer source, to KCl, on the production of Mesa Russet potatoes at the San Luis Valley of Colorado, USA. Treatments included (1) the control treatment where no K fertilizer was applied, (2) application of KCl pre-plant (KCl PP), (3) application of K acetate pre-plant (KAc PP), (4) foliar application of K acetate (KAc F), (5) K acetate pre-plant and foliar (KAc PP + F), and (6) foliar application of K acetate twice (KAc 2 F). KAc PP and KAc F treatments increased total tuber yield and marketable tuber yield (> 114 g) compared to KCl PP treatment in both years. Measurements of tuber quality (tuber dry weight, specific gravity, cracks, knobs, and hollow heart) and plant growth (tuber bulking, aboveground biomass, stem number, and tuber number) showed no consistent treatment impacts. Supplemental application of K acetate (pre-plant or foliar) improved tuber yield of Mesa Russet potatoes; however, the mechanism through which K acetate achieved these yield gains remains unclear and warrants additional research.

Tissue‐Specific Plasticity of DNA Methylation Across Intertidal Microhabitats in Juvenile Mussels ( Mytilus californianus ) - Qiting Cai; Samuel N. Bogan; Richelle L. Tanner; Joanna L. Kelley; W. Wesley Dowd (Molecular Ecology, 2026)
Epigenetic modifications to DNA are proposed to underpin plastic responses to environmental change, and the manner in which DNA methylation contributes to plasticity likely differs among tissues. However, few studies have investigated tissue‐specific DNA methylation responses to ecologically relevant environmental stressors in natural settings. Here, we used reduced representation bisulfite sequencing to examine the influence of in situ microhabitats on DNA methylation in gill and foot of juvenile California mussels ( Mytilus californianus ), a foundation species with widespread dispersal and little evidence of genetic population structure. We examined mussels from a one‐month reciprocal transplant experiment between a cool, wave‐exposed and a warm, wave‐protected microhabitat. These manipulations—which were previously shown to alter juvenile mussels' heat tolerance—led to significant and tissue‐specific changes in CpG methylation, including within a number of genes with roles in stress response pathways. Differentially methylated genes were involved in processes including heat shock response, proteolysis, and temperature sensing. In gills, differentially methylated CpGs were more likely to occur in introns relative to other inter‐ and intragenic features. This study expands on previous research that examined environmentally driven shifts in DNA methylation by documenting plastic and tissue‐specific changes in DNA methylation between microhabitats in a natural setting.

Tariqilabeo kaladanensis , a new species of fish ( Teleostei: Cypriniformes ) from the Kaladan basin of Mizoram , northeast India - Mualchin Zirkunga; Lalramliana; Chawngthu Zothansanga; Mahender Singh; Samuel Lalronunga (Journal of Fish Biology, 2026)
A new labeonin fish, Tariqilabeo kaladanensis , is described from the Kaladan River of Mizoram, northeast India. The new species is distinguished from its congeners by having combination of the following characteristics: frenum of rostral cap exposed, folded and continuous with the subtoral fold, frenum of upper lip covered by the rostral cap, presence of dark humeral spot covering 4th and 5th lateral‐line scales extending to scales immediately above and below lateral‐line scales, 32–34 lateral‐line scales, lacking mid‐lateral stripe on the flank and possessing 28–29 gill rakers on the first‐gill arch. The morphological distinction of the new species is well supported by the mitochondrial gene data with a wide genetic distance of 4.1%–12.7% ( coi ) and 7.2%–15.6% ( cytb ) from all other congeners.

What Have We Learned From Empirical Applications of Modern Coexistence Theory? - Peter B. Adler; Matteo Detto; Stephen P. Ellner; Theo L. Gibbs; Zachary J. Gold; Samuel J. Leonard; Jacob I. Levine; Annie E. Schiffer; Chuliang Song; Michael Stemkovski; Megan L. Vahsen; Jonathan M. Levine (Ecology Letters, 2026)
Since the early 2000's, Modern Coexistence Theory (MCT) has guided empirical investigations of coexistence. We reviewed empirical applications of MCT to answer two questions: (1) What have we learned about the strength of temporal, spatial and variation‐independent mechanisms of coexistence in nature? (2) How have studies of niche and fitness differences advanced our understanding of coexistence? With respect to the first question, we now have evidence that the temporal storage effect and variation‐independent mechanisms help stabilize coexistence in many systems. We have not learned more due to the low number of tests of these mechanisms (24 out of 84 MCT studies), the narrow focus on mechanisms involving temporal variation and grassland communities, and lack of rigorous model validation. With respect to our second question, studies of niche and fitness differences (61 of 84 studies) have answered fundamental questions about the role of phylogenetic relatedness, plant–soil feedbacks, and functional traits in coexistence. We recommend that future empirical MCT studies (1) match hypotheses to MCT quantities, (2) address gaps in empirical studies, (3) avoid known biases in estimating competition coefficients, and (4) validate models with independent data.

Transient dynamics and nonlinear fitness: A matrix approach to pulse and press perturbation - Harman Jaggi; Shripad Tuljapurkar; Wenyun Zuo; Samuel J. L. Gascoigne; Maja Kajin; Roberto Salguero‐Gómez (Ecology, 2026)
Disturbances can occur as short‐lived pulses (e.g., storms) or sustained presses (e.g., chronic drought). Much work in ecology has developed methods to help predict how natural populations respond to disturbances, but analyses of pulse and press disturbances have been largely disconnected. We present a matrix framework that links press and pulse perturbations within the same analytical approach, showing how transient nonlinearities and demography shape fitness. We find that transient responses to pulse perturbations accumulate to determine the long‐term response to press disturbances. For structured population models, this cumulative change is given by a new transient response matrix (TRM). Strikingly, the TRM also yields the second derivatives of the population growth rate with respect to matrix elements. Thus, there is an intimate but unexpected relationship between nonlinear selection pressures on demographic rates, and the transient dynamics of populations. This relationship yields a strong correlation between TRM and generation time across 439 unique plant and animal species (2690 population models). We also show that the TRM is directly related to Cohen's cumulative distance measure for populations converging to stability. Our framework provides ecologists with a general tool to predict population responses to diverse environmental changes.

Distinguishing climate change worry from state climate anxiety across 32 countries: implications for subjective wellbeing - Eun Hee Lee; Charles Adedayo Ogunbode; Sibele Aquino; Navjot Bhullar; Mai Albzour; Rahkman Ardi; Arin H. Ayanian; Aydin Bayad; Laura Martinez Buelvas; Razieh Chegeni; JohnBosco Chika Chukwuorji; Rouven Doran; et al. (Journal of Environmental Studies and Sciences, 2026)
The concepts of “climate change worry” and “climate change anxiety” are often used interchangeably in climate research, but they may reflect distinct emotional responses to climate change, which could potentially have different implications for public mental health. This research brief aims to empirically examine the differences between these two constructs by comparing their associations with key indicators of subjective wellbeing. Using survey data from 32 countries ( N = 12,246), we compared how strongly climate change worry and state climate anxiety were each associated with subjective wellbeing, as measured by the WHO-5 Wellbeing Index and life satisfaction. State climate anxiety showed stronger associations with both WHO-5 Wellbeing Index and life satisfaction than climate change worry. This underscores the importance of treating the two as distinct emotional responses, each with different implications for public wellbeing. These insights are especially relevant for policymakers and climate communicators, who must carefully consider the emotional tone of climate messaging to foster constructive engagement while safeguarding the psychological wellbeing of the public.

Field Experiments on Health and the Built Environment in Urban Settings: A Scoping Review - Alexandra Bretones Diaz; Samuel Nello-Deakin; Jordi Honey-Rosés (Current Environmental Health Reports, 2026)
Purpose of Review Science has long examined how the built environment impacts health and wellbeing, yet most research has relied on observational and longitudinal studies. Much less attention has been paid to field experiments as a method to understand how environmental conditions may impact health. Although formal field experiments are common in public health, environmental psychology and related fields, they remain rare in urban planning and design despite their potential to inform how urban transformations may improve health and wellbeing. This scoping review examines how field experiments have been used to assess the health and wellbeing impacts of the built environment. Recent Findings Following an extensive keyword search, we identified studies published between 2015 and 2025 that employed a field experimental design in an urban or peri-urban context and directly assessed health-related outcomes associated with built environment characteristics or interventions. A total of 26 studies met the inclusion criteria and were analysed according to their topical focus, methodological design, assessed health outcomes, and reported challenges and limitations. Most studies focused on the health and wellbeing impacts of exposure to urban green features, accounting for over two thirds of reviewed studies. Mental health and wellbeing outcomes were assessed more frequently than physical health outcomes, often through a combination of self-reported and objective physiological measures. Only a limited number of studies involved direct interventions or transformations of the built environment, while most compared existing environmental conditions. Summary The limited number of field experiments addressing issues beyond urban green features suggests there is considerable opportunity to expand the use of field experiments to assess the health impacts of other types of built environment interventions, particularly in the context of the growing popularity of tactical urbanism and temporary urban transformations.

Multi-Isotopic approach to trace the provenance and trajectory of sinking particles in the Ulleung Basin, East Sea (Japan Sea) - Sun-A Lee; Hojung Kim; Young-Il Kim; Shigeyoshi Otosaka; Michael Bollen; Patrick Blaser; Negar Haghipour; Tae-Ho Yoon; Hui Tae Joo; Samuel L. Jaccard; Timothy I. Eglinton; Minkyoung Kim (Frontiers in Marine Science, 2026)
The Ulleung Basin (UB), in the East Sea (Japan Sea) hosts a long-term ocean monitoring station with a time-series sediment trap. We present new 1-year sinking particle fluxes, along with organic (radiocarbon) and inorganic (detrital neodymium; ϵNd -detrital ) isotopic compositions of sinking particles and surface sediments in order to constrain lateral particle advection. The εNd -detrital values of the Korean Peninsula and the Japanese Islands bedrocks differ distinctly, and the εNd -detrital values of surface sediments increase eastwards showing strong contrasts in sediment provenance. This suggests that the εNd -detrital signature of sinking particles may serve as a robust approach to trace particle provenance and transport in the UB, although the present ϵNd -detrital dataset is preliminary due to limited temporal coverage. Sinking particles collected at 1000 m and 2000 m depth in the UB exhibited a similar range in ϵNd -detrital to those of surface sediments throughout the year. The ϵNd -detrital values at 300 m depth were tended to be lower than those at 1000 m and 2000 m depths, with the lowest value observed in winter. Our observations suggest that lithogenic material accumulating in the upper sediment trap was potentially transported from the adjacent shelf area via northward transport, while those at greater depths were predominantly influenced by local sediment resuspension. Along with radiocarbon analyzes of sinking particulate organic carbon, our results highlight the importance of lateral transport and local sediment resuspension as key mechanisms regulating the supply of pre-aged organic carbon associated with lithogenic materials to the UB.

Factors associated with methicillin resistance in Staphylococcus aureus: a case–case–control analysis of AMR surveillance data - Godwin Pius Ohemu; Md. Kaisar Rahman; Yamima Tasnim; Samuel Ajulo; Babafela Awosile (European Journal of Clinical Microbiology & Infectious Diseases, 2026)
Objective This study examined clinical, demographic, and geographic factors associated with methicillin-resistant and methicillin-susceptible Staphylococcus aureus (MRSA and MSSA) isolation in a global surveillance dataset. Method We analyzed Antimicrobial Testing Leadership and Surveillance (ATLAS) data (2004–2021) from 61 countries using a case-case-control design comparing MRSA and MSSA cases with Enterococcus spp. controls. Multivariable regression assessed factors associated with isolation. Model performance was assessed using VIF (< 2), Hosmer-Lemeshow tests ( p > 0.05), and ROC-AUC (> 0.94). Results We analyzed 155,482 isolates (54,599 MRSA, 63,101 MSSA, 37,782 Enterococcus). Models showed excellent discrimination (ROC-AUC: 0.945 for MRSA, 0.943 for MSSA). Substantial variation in isolation patterns was observed across countries. Compared with the United States, the relative MRSA odds were higher in Venezuela (OR = 1.66), Colombia (OR = 1.63), and Taiwan (OR = 1.57), while MSSA odds were higher in India, Kuwait, Brazil, Chile, Taiwan, and Israel. Compared with infants aged 0–2, children aged 3–12 and adolescents aged 13–18 years had higher odds of both MRSA and MSSA isolation. Relative to general surgery units, both MRSA and MSSA were more frequently isolated from the emergency and general medicine units. Compared with abdominal fluid samples, MRSA odds were highest in sputum (OR = 28.68), while MSSA showed a similar pattern in sputum (OR = 31.60), lower respiratory tract samples (OR = 26.26), abscesses (OR = 11.79), and wound samples (OR = 7.38). MRSA isolates also showed higher odds of levofloxacin co-resistance (OR = 11.19). Conclusion This analysis describes variation in MRSA and MSSA characteristics across ATLAS settings. These findings may inform region-specific infection control strategies and highlight the need for continued global antimicrobial resistance surveillance.

CA Inhibitor 1 Treatment Does Not Affect Estrous Cyclicity in Mice - Laura L. Giacometti; Donna Mae Dalere; Bupe Lwamba; Samuel L. Goldberg; Kaitlyn Feliciano; Jacqueline M. Barker (Journal of Neuroimmune Pharmacology, 2026)
Approximately 45% of new HIV infections worldwide occur in women and girls and adherence to pre-exposure prophylaxis (PrEP) to prevent HIV infection is limited, particularly in women. Long-acting PrEP such as lenacapavir may improve adherence. One barrier to PrEP usage in women and girls is impact on the menstrual cycle, though impacts of long-acting PrEP are unclear. To model the effect of lenacapavir administration on cyclicity, adult female C57Bl/6J mice were injected with capsid (CA) inhibitor, an analog of lenacapavir, 1 and assessed for estrous cyclicity. Injection of either CA inhibitor 1 did not impact estrous cycle. CA inhibitor 1 did not impact astrocyte immunoreactivity or chronic cellular activity in the medial preoptic area (mPOA), a major regulator of the estrous cycle. These findings warrant further investigation into the effects of lenacapavir on menstrual cycle as it may promote PrEP adherence for those concerned with PrEP impacts on menstrual cycle.

Potential Viability of Repurposing Abandoned Hydrocarbon Wells for Geothermal Energy Production: Case Study—Volve Field, North Sea - Housameddin Sherif; Amilcar Soares; Ana Margarida Luis de Sousa; Samuel Rivas; Ziad Bennour (Mathematical Geosciences, 2026)
Repurposing of oil and gas wells for geothermal energy involves several critical steps, including assessing the well’s structural integrity, evaluating the reservoir’s thermal properties, and modeling the potential energy output. The development of geothermal systems is naturally uncertain due to sub-state conditions, thermal conductivity, and inequalities in fluid flow behavior. Reliable performance forecasting and optimal well design depend on this rigorous modeling and simulation. As a result, global interest in sustainable energy has accelerated the use of abandoned oil and gas wells as viable resources for geothermal energy production. This study investigates the feasibility of repurposing abandoned oil wells in the Volve oil field in the North Sea as geothermal energy sources. This research shows the effects of petrophysical properties (i.e., permeability and porosity) on enthalpy production derived from reservoir modeling, and examines the uncertainty in these properties to achieve more accurate reservoir characterization and modeling. The following methodological framework was employed: First, reliable and coherent three-dimensional models of petrophysical properties were developed using geostatistical sequential simulations to improve well log data and spatial patterns as revealed by spatial covariances and variograms. Next, these models were updated to align with historical production data. After validation, the models were utilized to forecast enthalpy production. Based on the results, the Volve reservoir can produce an average of 2,094 MWh of geothermal energy each year, yielding a total energy output of about 41,877 MWh over a 20-year operating period.

Time-resolved network metabolomics reveals metabolic reprogramming and network stability in cowpea leaves during virus infection - Raissa S. C. Bret; Silvio A. Cândido-Sobrinho; Samuel G. Abreu; Nicole P. Porto; David B. Medeiros; Leonardo Perez Souza; Murilo S. Alves; Alisdair R. Fernie; Danilo M. Daloso (Theoretical and Experimental Plant Physiology, 2026)
Cowpea severe mosaic virus (CPSMV) represents a major constraint for cowpea ( Vigna unguiculata (L.) Walp.) cultivation. However, the metabolic basis underlying CPSMV resistance remains poorly understood. Given the importance of metabolism for plant defence against pathogens, we hypothesized that cowpea resistance to CPSMV is associated to the activation of defence-related pathways from both primary and secondary metabolisms. We investigated the metabolic dynamics associated with CPSMV infection in the resistant cowpea genotype Macaibo using a time-resolved, network-based metabolomics approach. Conventional RT-PCR suggests that the intensity of the CPSMV coat protein band increased in the first eight H ours A fter CPSMV I noculation (HAI) but appeared reduced in the following 72 HAI. Metabolomic analyses revealed that CPSMV infection had little impact on secondary metabolism, whereas several primary metabolites were significantly altered over time. Transient increases in fumarate, pyruvate, and several amino acids, including alanine, asparagine, glutamine, glutamate, isoleucine, leucine, proline, serine, threonine, and valine, were observed at 48 HAI compared with mock-treated leaves. Network analysis indicated that overall metabolic network density and heterogeneity remained relatively stable during infection. However, a highly connected metabolic module composed of the branched-chain amino acids (BCAAs) isoleucine, leucine, and valine emerged in infected leaves. Our results indicate that CPSMV infection reshapes primary metabolic dynamics without extensive alterations in secondary metabolism during early infection in cowpea leaves. Despite these metabolic adjustments, the overall metabolic network structure remained stable, suggesting that a robust metabolic reprograming, including the activation of BCAA-associated pathways, may help buffer viral perturbation in cowpea leaves.

Surfaces with no drainage: Reconnaissance assessment of the hydrogeologic significance of pockmarks in African drylands - Seifu Kebede; Ashebir Belay; Behailu Birhanu; Samuel Godfrey (Hydrogeology Journal, 2026)
This study presents a reconnaissance investigation into the occurrence, typology, and hydrogeologic significance of pockmarks in African drylands. These unique geomorphic depressions, characterized by poorly developed or disconnected drainage networks, occur on a surface covering more than 10 million km 2 of the continent. Despite their widespread presence, pockmarks remain understudied in hydrogeology and their significance in local groundwater security is rarely investigated. Using an integrated methodology that combines remote sensing, digital elevation models, literature review, and field isotope hydrological investigations, this study identifies and classifies five major pockmark types. Evidence from the isotope hydrology study in Ethiopia reveals their vital role in focused groundwater recharge, temporary surface water storage, and promoting the occurrence of perched groundwater systems in otherwise groundwater-scarce environments. The depressions are shown to be critical for supporting biodiversity, ecosystem services, and water security in arid and semi-arid regions. This study highlights the hydrogeologic significance of these features and calls for an increased hydrogeological investigation.

Spatiotemporal changes in precipitation concentration in São Francisco River basin - Antonio Samuel Alves da Silva; Moacyr Cunha Filho; Ivanildo Batista da Silva Júnior; Borko Stosic; Tatijana Stosic (Theoretical and Applied Climatology, 2026)
We analyzed the temporal and spatial variability of precipitation concentration in the São Francisco River basin (SFRB), Brazil, on annual, and seasonal scales using the precipitation concentration index (PCI). The PCI was calculated from a high-resolution daily precipitation gridded dataset for the period 1961–2022. Annual and seasonal PCI values were used to investigate significant trends by applying the Modified Mann–Kendall (MMK) test and to assess the impact of climate change by comparing two 31-year climate periods (1961–1991 and 1992–2022). The results showed that precipitation concentration varies spatially across the SFRB, reflecting regional climate delineation and the distribution of wet and dry months. On an annual scale, the upper, middle and sub middle SFRB regions displayed irregular and highly irregular rainfall distribution while the lower SFRB region showed moderate precipitation concentration. In summer and autumn most of SFRB areas display moderate rainfall distribution, while in spring both moderate and irregular rainfall distribution were found in the middle and sub middle SFRB regions. In winter, irregular rainfall distribution was present in the upper SFRB, highly irregular rainfall distribution in the middle SFRB, moderate rainfall distribution in the sub middle SFRB and uniform distribution in the lower SFRB. Across almost the entire SFRB moderate rainfall distribution was found in wet season and highly irregular distribution in dry season. The most significant change from the first to the second period was found in the seasonal rainfall regime: in winter, the area with low precipitation concentration, indicating uniform rainfall distribution, increased to 100% in the Lower SFRB region (wet season and subhumid climate); in spring, the area with irregular rainfall distribution increased from 23 to 77% in the Middle SFRB (transition from dry to wet season and semiarid climate). The MMK test, applied for the entire period (1961–2022), showed that in summer and spring, a significant positive trend in PCI values was observed for large areas of the SFRB (57% and 58%, respectively), indicating that rainfall distribution has become more irregular. This irregularity can affect energy generation, agricultural planning and production, and water resources management. In both wet and dry seasons, positive trends were found across the central and northern areas of the middle, sub-middle, and lower SFRB, indicating an increasing risk of floods and droughts in these regions.

Single prolonged stress in mice: interactions between alcohol drinking, negative affect, and fear learning - Aditi B. Buch; Ava L. Shipman; Nicolas J. Azzarello; Annie W. Zhou; Samuel W. Centanni (Psychopharmacology, 2026)
Rationale & objective Exposure to traumatic stressors can have detrimental effects on one’s well-being. Alcohol is often used as a coping mechanism to alleviate stress, leading to the development of alcohol use disorder (AUD). Furthermore, sex dimorphisms in stress and AUD alter their progression and sustenance. To investigate these interactions for effective treatment strategies, validated and exhaustive preclinical models are necessary. Here, we designed a comprehensive study that examines how traumatic stress influences ethanol drinking patterns and PTSD-like phenotypes in male and female mice with Single Prolonged Stress (SPS). Methods Male and female C57BL/6 J mice underwent SPS, a model of traumatic stress consisting of a series of consecutive stressors, followed by a 7-day stress incubation period. Mice then underwent a series of tests for aversive state, fear discrimination, and drinking patterns during continuous and limited ethanol access. Results & conclusions SPS selectively increased negative affect and startle responses in male mice, while females were unaffected. SPS disrupted discrimination adjustment between fear and safety cues during extinction, while ethanol exposure attenuated overall fear responses. SPS maintained baseline sex differences in consumption. Furthermore, female consumption increased when access was provided prior to and continuously throughout SPS and fear conditioning, contrasting with groups exposed to ethanol afterwards. In summary, we identified a distinct sex specific relationship between traumatic stress, fear memory, and the timing of ethanol consumption. We highlight SPS as a robust translational model for exploring the sex-specific neurobiological mechanisms driving traumatic stress-induced affective disturbances.

Chemogenetic activation of medial prefrontal cortex projections to the nucleus accumbens shell suppresses cocaine-primed reinstatement in EcoHIV infected mice - Qiaowei Xie; Mark D. Namba; Rohan Dasari; Lauren A. Buck; Christine M. Side; Samuel L. Goldberg; Kyewon Park; Joshua G. Jackson; Laura Giacometti; Jacqueline M. Barker (Psychopharmacology, 2026)
HIV is highly comorbid with cocaine use disorder (CUD). Relapse is a major challenge in the treatment of CUD, and people living with HIV (PLWH) exhibit shorter time to relapse. One driver of relapse may be re-exposure to cocaine, which can be modeled in rodents using cocaine-primed reinstatement. This process involves neuroadaptations within the medial prefrontal cortex (mPFC) and nucleus accumbens (NAc) shell, regions that mediate cocaine reward learning and relapse-related behavior. HIV infection interacts with cocaine to alter corticostriatal circuits, which may further dysregulate cocaine seeking. To investigate the impact of HIV infection on cocaine reward learning and reinstatement and the role of mPFC-NAc circuits, we utilized the EcoHIV mouse model, a chimeric form of HIV-1 which can infect wild-type mice. Our findings demonstrate that EcoHIV infection enhances cocaine-primed reinstatement. We also observed increased cocaine-induced expression of the cellular activation marker cFos in the NAshell in EcoHIV-infected mice. Given the role of the mPFC-NAshell circuit in cocaine-seeking behaviors, we further demonstrated that chemogenetic activation of this circuit could reverse the behavioral deficits induced by EcoHIV. We propose that HIV infection contributes to neuroadaptations in the mPFC-NAshell circuit, and enhancing its activity may inhibit relapse-related behavior. These findings indicate that key neuronal circuits underlying cocaine reinstatement are similarly implicated in HIV infection and suggest potential strategies for managing relapse in PLWH.

Role of autonomic receptors in ethyl ferulate-induced cardiovascular effects in normotensive and hypertensive female rats - Francisca Valdirene de S. Nunes; Samuel S. P. Araujo; Juliana A. da Silva; José Guilherme V. de Assunção; Ariell A. de Oliveira; Carlos E. R. Dourado; Vandercley de O. Damasceno; Aldeídia P. de Oliveira; Maria do Carmo C. Martins; Mayara C. de Morais; Damião P. de Sousa; Thyago M. de Queiroz; et al. (Pflügers Archiv - European Journal of Physiology, 2026)
Aims Ethyl ferulate (EF) may offer novel benefits in hypertension. We investigated the contribution of autonomic receptors to EF-induced effects in female Wistar and SHR. Methods Anesthetized females received EF intravenously at 7.5, 15, or 30 mg/kg. Autonomic involvement was evaluated using pretreatment with atropine, atenolol, or hexamethonium. MAP and HR were continuously monitored. Results EF induced rapid and pronounced reductions in MAP and HR in both strains. In Wistar rats, muscarinic and nicotinic blockade significantly attenuated these responses. In SHR, atropine abolished bradycardia and partially mitigated hypotension, whereas β1-adrenergic and nitric oxide synthase inhibition had minimal impact. Conclusion EF acutely lowers MAP and HR, with muscarinic and nicotinic receptors driving the effects in normotensive females, and muscarinic pathways partially mediating responses in hypertensive females. These results position EF as a compelling candidate for antihypertensive therapy and underscore the critical need to study cardiovascular interventions in female hypertension models.

Tropical cyclone landfall intensity (Vmax) for western North Pacific nations: return period and trends - Samuel S. Bell; Savin S. Chand; Philip J. Klotzbach; Marie Ekström; Valentina Koschatzsky; Sarvesh Kumar; Krishneel K. Sharma; Mona Hemmati (Natural Hazards, 2026)
Human impacts, including financial losses, are closely related to the intensity and frequency of tropical cyclone (TC) landfalls in the western North Pacific (WNP) region. Here, 44 years of observational TC wind speed (V max ) and track records (1980–2023) are used to examine TC landfall intensity trends and recurrence. Analysis is conducted over individual nations and includes modulation by El Niño-Southern Oscillation (ENSO), which has recently exhibited increasing asymmetries in spatial and temporal evolution. Two modern ENSO indices are first evaluated before one is selected to classify TC seasons into canonical phases. Landfall trends over individual nations are insignificant, but significant decreases are noted for the northern Philippines and parts of Micronesia, including for intense (> 33 m s –1 ) V max . However, the distribution of upper-tail V max values increases for 5 of 7 nations over the recent period, including the Philippines and Micronesia, confounding the impact of the much-noted poleward shift in WNP TC activity. Ex-TC landfall trends, while less robust, are also evaluated, and shown to have increased over the southwest corner of Japan. Lastly, a modified return period framework is employed to estimate the recurrence of V max at various locations based on “peak average” speeds and the shape of a reference extreme value curve. The framework provides a consistent platform for estimating long-term return magnitudes with limited data, such as V max over land. 1-in-200 year V max intensities are estimated to be the highest over the Philippines, southern Japanese islands and Micronesia, and relatively lower over Vietnam, Korea and China.

Defining a lipophilicity window for the antimicrobial activity of 7-Alkoxy-3-Amino coumarin amphiphiles - Samuel O. Nitschke; Alysha G. Elliott; Shane M. Hickey; Sally E. Plush (Medicinal Chemistry Research, 2026)
The continued rise of antimicrobial resistance (AMR) demands the research and development of novel antimicrobial agents that act via mechanisms less prone to resistance. Cationic antimicrobial peptides (CAMPs) are naturally occurring molecules that exhibit potent antimicrobial activity but have not encountered significant AMR. Synthetic mimetics of CAMPs offer a cost-effective route to new antimicrobials. We have previously reported a series of amphiphilic coumarin derivatives that elicit potent activity against several pathogenic bacterial strains, including planktonic methicillin-resistant Staphylococcus aureus (MRSA) and MRSA biofilms. Although compound lipophilicity plays a significant role in antimicrobial activity, this relationship needs to be accurately defined for each class of compound to facilitate the design of improved therapeutic agents. In this study, six cationic coumarin amphiphiles were designed with varying lipophilic character. These compounds were synthesised, characterised, and evaluated against a panel of clinically relevant pathogenic bacteria ( Escherichia coli , Klebsiella pneumoniae , Acinetobacter baumannii , Pseudomonas aeruginosa , and MRSA) and fungi ( Candida albicans and Cryptococcus neoformans ), to establish a lipophilic range that correlates to potent activity for this family of compounds. Our results suggest that when these compounds exist in their cationic state, a cLog P range of 0.75–1.82 correlates with best activity, with minimum inhibitory concentration (MIC) values as low as 0.02 µg/mL against C. neoformans and 1 µg/mL against MRSA obtained for derivatives that fall within this lipophilicity window.

Contrasting Drivers of Genetic Diversity in Plants Across Previously Glaciated Northern Hemisphere Landscapes - Lu Liu; James S. Borrell; Samuel Pironon; Nian Wang (Global Ecology and Biogeography, 2026)
Aim Understanding how global biogeographical and evolutionary processes have shaped continental scale patterns of plant genetic diversity is increasingly tractable, given the proliferation of population genetic data. Predominant theories are the geographical central‐marginal hypothesis (CMH), ecological CMH and historical CMH which predict decreasing genetic diversity from range centres to margins, from suitable to marginal environments, and from refugia to newly colonised areas, respectively. In addition, the latitudinal gradient (LG) and longitudinal gradient (LoG) hypotheses predict a decrease of within‐population genetic diversity along dispersal routes across species ranges. Here we test these hypotheses across North America (NA), Europe (EU), and East Asia (EA), which experienced contrasting patterns of post‐glacial landscape fragmentation. Location North America, Europe and East Asia. Time Period The last glacial maximum to present. Major Taxa Studied Plants. Methods We collated data from 8333 populations, representing 435 plant species and calculated distances from populations to the range margin, climatic niche margin and refugia, latitude and longitude. We applied Bayesian phylogenetic mixed‐effects models to assess the relationship between these variables and genetic diversity. All possible combinations of the five variables were constructed, yielding 31 candidate models, and the best‐supported model was identified through model comparison. Results We found that the geographical CMH, ecological CMH, historical CMH, LG and LoG have shaped patterns of genetic diversity across the Northern Hemisphere, but varied substantially by region and between woody and herbaceous species. Specifically, the geographical CMH has mainly shaped genetic diversity of herbaceous species in the EU and EA whereas the ecological CMH mainly impacted that of woody species in NA. The historical CMH has limited impacts on patterns of genetic diversity in EA. Main Conclusions Our analyses illustrate contrasting drivers of spatial genetic diversity across continents, reflecting heterogeneous impacts of historical glaciation interacting with life history traits. Our results underscore the value of geographical, historical and ecological variables as proxies for within population diversity, enabling identification of populations or regions that could be prioritised for conservation in previously glaciated Northern hemisphere.

Landscape Connectivity and Wildlife Access to Water Across an International Border: Barriers and Opportunities for Facilitating Transboundary Movement - Bogdan Chivoiu; Erin L. Koen; Michael J. Osland; Christopher A. Gabler; Jerald T. Garrett; Ernesto Reyes; Stephanie A. Bilodeau; Mitch A. Sternberg; Miguel L. Villarreal; Eric K. Waller; Samuel N. Chambers; Jude A. Benavides; et al. (Global Change Biology, 2026)
Rapid global acceleration in the construction of physical barriers along international borders has greatly influenced biodiversity and animal movement. Physical barriers can fragment landscapes, hinder access to essential resources, impact long‐distance migrations, and inhibit dispersal and gene flow. The effects of physical barriers on animal movement and landscape connectivity can be exacerbated in dryland environments where access to water is a limiting factor. In recent decades, the construction of border barrier infrastructure has accelerated along the international boundary between the United States and Mexico. Here, we used a landscape connectivity model to investigate the effects of barriers on wildlife access to the river in the Lower Rio Grande Valley. We used a modified omnidirectional connectivity model to compare access to the river for three large, terrestrial mammal species across three border barrier scenarios: (1) a landscape without border barriers; (2) a landscape with the existing barrier system; and (3) a potential future landscape with a continuous barrier system. The existing barrier system includes many discrete sections of barrier within tracts of the Lower Rio Grande Valley National Wildlife Refuge or on lands associated with the region's flood control system. Our results indicate that the existing border barriers can impede connectivity and wildlife access to the river in some areas, while some existing gaps between border barrier sections can serve as conduits for wildlife movement and river access. Our future scenario results show how a potential continuous border barrier system could further impede wildlife access to the river. We discuss management and landscape conservation options for enhancing wildlife access to water and riverine habitats. Collectively, our results illustrate the potential effects of border barriers on wildlife movement and access to water, providing information that can be used to better anticipate and lessen the ecological impacts of transboundary barriers.

Transient tracer observations in the Gulf of St. Lawrence reveal shift from younger to older inflow waters - Lennart Gerke; Toste Tanhua; William A. Nesbitt; Samuel W. Stevens; Douglas W. R. Wallace (Ocean Science, 2026)
The deep waters of the Gulf of St. Lawrence (GSL) have experienced a significant reduction in dissolved oxygen content during the past decades. One widely documented driver of this deoxygenation is a change in the composition of the deep inflowing water that ventilates the Gulf, which consists of a mixture of warmer, less-oxygenated North Atlantic Central Waters (NACW) and cooler, more-oxygenated Labrador Current Waters (LCW). While previous studies have inferred changes in this inflow from hydrographic and biogeochemical observations, direct constraints on deep-water ventilation timescales have been lacking. Here, we present the first spatially-comprehensive measurements of transient tracers (SF6 and CFC-12) in the GSL, allowing direct estimates of tracer-derived mean ages and ventilation timescales throughout the deep layer. Mean ages increase systematically with density and exhibit a pronounced along-channel gradient, with younger waters (30–40 years) in the Lower St. Lawrence Estuary and older waters (50–60 years) toward Cabot Strait. This west-east increase in ventilation age is more gradual than corresponding changes in temperature and salinity, indicating that tracer-derived ages respond differently to variations in source water composition than hydrographic properties. The observed gradual age structure is consistent with a greater influence of older, earlier ventilated NACW in the eastern Gulf, while younger ages inland reflect a continued contribution of LCW. These results demonstrate that, as of 2022, the shift toward longer deep-water ventilation timescales, and associated changes in inflow properties toward higher NACW composition, is ongoing rather than having reached a steady end state, contrary to earlier predictions.

Molecular relatedness-based analyses reveal breeding site philopatry in female bluntnose sixgill sharks (Hexanchus griseus) - Shawn Larson; Dayv Lowry; Kelly Andrews; Claude Dykstra; Francis Juanes; Brian Timmer; Samuel May (Frontiers in Marine Science, 2026)
The bluntnose sixgill shark ( Hexanchus griseus ) is a deep-water, globally distributed, but data-limited species due to its habitat use and cryptic nature. Its slow growth, long lifespan, and uncertain population status have prompted concern about its vulnerability and resulted in an IUCN Red List status of “Near Threatened.” A lack of information about critical habitat use throughout the species’ life cycle, such as breeding grounds, complicates direct management of the species. This study investigates the genetic diversity, population structure, relatedness, and reproductive behaviors of sixgill sharks in the Salish Sea, an inland fjord encompassing Washington State, USA and British Columbia Canada, one of the few known pupping and rearing grounds of the species globally. Using genomic sequencing of 274 tissue samples opportunistically collected over a 16-year timespan, we found no evidence of spatial or temporal genetic population structure within the Salish Sea and moderate levels of neutral genetic diversity. Multiple paternity in two litters confirmed polyandrous mating, a strategy that may enhance genetic diversity. Relatedness analyses revealed philopatry, with close relatives identified across disparate years, demonstrating that mature females or their relatives return to this nursery ground over time for pupping. These findings provide new insights into the life history of the sixgill shark and emphasize the critical role of nursery habitats, such as the Salish Sea, in their reproductive success, underscoring the need for targeted conservation efforts to protect these sharks and their known critical habitats.

Decline in cardiorespiratory fitness and its association with vascular aging and subclinical atherosclerosis in healthy older adults: a 3-year longitudinal study - Vincent Groesser; Christopher Weyh; Torsten Frech; Natascha Sommer; Klaus Eder; Astrid Most; Samuel Sossalla; Karsten Krüger; Pascal Bauer (GeroScience, 2026)
Aging is associated with progressive deterioration of vascular function and cardiovascular risk. Cardiorespiratory fitness (CRF) is closely associated with cardiovascular health, yet longitudinal data in healthy older adults remain limited. This study examined 3-year changes in vascular and echocardiographic parameters in older adults and their associations with CRF and muscle strength. Forty-nine participants (mean age 63.8 ± 3.8 years) underwent vascular assessments (brachial/central blood pressure (BP), pulse wave velocity (PWV), augmentation index), echocardiography, CRF testing via spiroergometry to determine VO 2 peak, muscle strength testing, and carotid sonography at baseline and after 3 years. Participants were grouped by carotid plaque status: no atherosclerosis, existing atherosclerosis, or newly developed atherosclerosis. Over 3 years, CRF and muscle strength (grip strength, leg flexion) declined significantly (all p < 0.005), while systolic BP ( p = 0.042), brachial-ankle PWV ( p = 0.006), and echocardiographic parameters including aortic root diameter and ventricular dimensions increased (all p < 0.001). Participants with newly developed atherosclerosis showed the greatest CRF decline ( p = 0.012). Changes in CRF were inversely associated with changes in systolic, diastolic, and central BP (all p < 0.01). Declines in leg flexion strength were also linked to larger BP increases. Participants maintaining > 90% of baseline VO 2 peak had significantly smaller BP increases. These results indicate that vascular aging progresses measurably within a few years in clinically healthy older adults and is associated with declines in CRF and muscle strength. Preservation of CRF is linked to more favorable vascular aging profiles and a lower prevalence of newly developed atherosclerosis. Graphical Abstract

Bidirectional associations between biological aging, cardiovascular health, and cardiovascular risk: findings from the INSPIRE-T lifespan cohort - Mathilde Strumia; Vanina Bongard; Samuel Thuriot; Philippe Cestac; Brigitte Sallerin; Jean-Marc Lemaitre; David Furman; Sophie Guyonnet; Bruno Vellas; Sandrine Andrieu; Laure Rouch; Sophie Guyonnet; et al. (GeroScience, 2026)
Chronological age is a common and non-modifiable factor for chronic disease, but does not fully explain age-related changes. Biological clocks have been developed to explore biological aging mechanisms. They could help identify protective factors against accelerated aging and associated diseases. We aim to assess the association between reduced epigenetic or inflammatory aging and ideal cardiovascular health or cardiovascular risk. We conducted a cross-sectional analysis of participants from the INSPIRE-T cohort. Cardiovascular health (CVH) was assessed using the Life’s Essential 8 score. Cardiovascular risk was assessed using the American Framingham risk score (FRS) and the European Systematic Coronary Risk Evaluation (SCORE2) score. Epigenetic and inflammatory aging was calculated from the residuals from linear regression of biological age (based on five epigenetic clocks and one inflammatory clock) and chronological age. Linear and logistic regression models were used. Better CVH has been associated with slower epigenetic aging, particularly in younger subjects and men. Accelerated epigenetic aging measured by GrimAge was associated with an increase cardiovascular risk (for SCORE2: OR = 1.10 95%CI [1.04; 1.16]). No persistent association was found with the inflammatory clock. Our study reported an association between ideal global CVH with reduced epigenetic aging after adjustment for chronological age and gender. This suggests that epigenetic aging may be modifiable through healthy lifestyle and cardiovascular risk management, although a potential underlying causal relationship remains to be established. Moreover, accelerated epigenetic aging is linked to worsening cardiovascular risk, and could be a new risk factor alongside chronological age. Graphical Abstract

Preoperative Traction for Pediatric Spinal Deformity Correction: A Technical Review - Samuel Wilcox; Megan Saalwaechter; Pavan Induraj; Brian Emling; Richard Welling; Colleen Coulter; Brian Giavedoni; Michael Schmitz; Yue Chen (Annals of Biomedical Engineering, 2026)
Purpose Severe pediatric spinal deformities often require preoperative traction to improve surgical safety and correction. This review examines the burden of deformities, current surgical approaches, and traction technologies to identify challenges and opportunities for improvement. Methods A two-stage literature review was conducted, first assessing the burden and surgical management of significant and severe pediatric spinal deformities, then focusing on traction modalities and associated technologies. Results Three primary traction approaches, halo gravity, halo pelvic, and halo femoral, were evaluated in addition to some recent alternative approaches. While clinically effective, their application remains highly variable in force delivery and inpatient protocols. Conclusion Preoperative traction remains the gold standard for severe pediatric spinal deformities, but current practices are inconsistent in force application. Standardization and modernization are needed to optimize outcomes and improve patient quality of life.

Novel genetic data for conservation monitoring of the false catshark (Pseudotriakis microdon) - Joana Marques; Samuel P. Iglésias; Carlos Ferreira; Filipe Pereira (Conservation Genetics Resources, 2026)
We present novel genetic data for the rare deep-water shark Pseudotriakis microdon , including sequences for COI, 16S rRNA, NADH2, and nuclear ITS2 from specimens sampled in the North Atlantic Ocean. These data, combined with all publicly available sequences, reveal clear genetic structuring: Atlantic and Indian Ocean populations form a cluster clearly separated from West Pacific individuals. The ITS2 marker, previously unreported for this species, appears particularly divergent, reflecting a poorly sampled phylogenetic branch and representing a valuable genomic resource. These findings lay the groundwork for future conservation and taxonomic studies of P. microdon populations.

Effect of the intestinal microbiota on TH17 cell-derived cytokines in the context of intestinal inflammation - Justus Neuendorff; Samuel Huber; Penelope Pelczar (Seminars in Immunopathology, 2026)
Inflammatory bowel disease (IBD) is a chronic and relapsing inflammatory condition of the gastrointestinal tract (GI tract). Despite extensive research, its exact pathogenesis remains elusive. However, multiple factors are thought to be involved in the onset and progression of IBD. Aside from genetic risk factors, microbial dysbiosis, environmental cues, defects in the epithelial barrier, as well as a dysregulated intestinal immune response, are critical players driving a vicious cycle, which ultimately results in chronic disease. An orchestrated interaction between the intestinal microbiota and the immune response, especially T H 17 cells, is critical for maintaining and re-establishing intestinal homeostasis. Nonetheless, a misguided interaction contributes to the pathogenesis of IBD. Indeed, depending on the microenvironment, intestinal T H 17 cells possess dual properties. Either they act to control the inflammatory response, or they acquire pro-inflammatory features promoting the development of intestinal pathology. This context-dependent phenotype of T H 17 cells has recently been associated with the microbiota composition, which shapes the inflammatory milieu of the gut. To establish precision immunomodulation as a therapeutic strategy for patients with IBD, it is critical to understand how intestinal microorganisms are involved in actively directing the dichotomous nature of T H 17 cells and their cytokine products.

Microplastic (MP) pollution has become a significant environmental concern, particularly in freshwater systems. However, little is known about the occurrence and characteristics of MPs in groundwater-fed freshwater sources such as natural springs. In this study, the presence, abundance and characteristics of MPs were investigated in freshwater natural springs across South Africa, representing different land-use types (i.e. rural and peri-urbanl) and spring type (i.e. modified and unmodified). On average, 6 particles per L (± 1.2 SD) of MPs were recorded, ranging between 2 (limit of quantification; LOQ) to 38 particles per L. Land-use and spring type did not show any significant influence on MPs abundance ( p > 0.05). Overall, MPs exhibited diverse characteristics. Fibres (67.8%) were the predominant shape, while blue (28.8%) was the most common colour. The dominant size class was 100–250 µm across all springs, while the dominant polymer was polyethylene (PE; 46.8%). Our findings suggests that groundwater-fed water sources like natural springs, regardless of their limited exposure to above ground environment, are equally at risk of MPs contamination, similar to surface freshwater systems. This research provides empirical evidence on MPs contamination and monitoring of remote ecosystems, highlighting the ecological and social risk of MPs pollution in important freshwater resources. The study contributes valuable data for understanding MP dynamics including their densities and sources from groundwater-fed freshwater resources, offering insights into broader environmental pollution to African systems.

A critical review of American Trypanosomiasis (AT) in dogs with the current distribution of cases in Brazil and a diagnostic approach for veterinary clinicians - José Atanásio de Oliveira Neto; Geovana Mergulhão da Silva; Samuel Souza Silva; Tatiene Rossana Móta Silva; Gílcia Aparecida de Carvalho; Leucio Câmara Alves; Rafael Antonio Nascimento Ramos (Veterinary Research Communications, 2026)
Trypanosoma cruzi (Kinetoplastea: Trypanosomatidae) is the etiological agent of American Trypanosomiasis (AT). Although knowledge of natural infection by T. cruzi in dogs has increased worldwide relatively few studies have evaluated this occurrence in Brazil, with much of the available information restricted to isolated case reports. The aim of this research was to provides a critical review of AT in dogs demonstrating the current distribution of cases in Brazil and to propose a diagnostic approach for veterinary clinicians. This review comprised a comprehensive search of scientific articles and case reports published, available at PubMed, Scielo and Google Scholar websites. A combination of keywords including “American Trypanosomiasis”, “Chagas disease”, “dogs”, “ T. cruzi ”, and “Brazil” was used for the search. Data from this review underscores the importance of dogs as domestic hosts of T. cruzi and provides the current distribution of this infection in these animals in Brazil. Additionally, it reveals important knowledge gaps regarding veterinarian awareness of T. cruzi and its diagnostic methods in small animal clinics. The diagnostic flowchart presented here serves to guide veterinarians to perform a proper diagnostic using currently available methods. The prevention of AT in dogs faces several challenges, including the domiciliation of triatomines and the misdiagnosis of cases. These factors contribute to the ongoing presence of untreated animals, which can serve as important sources of infection for triatomine vectors and ultimate risk of human infections. For the AT control, it is important to reinforce the necessity of a One Health approach and to underscore the role of veterinarians in this process. It is pivotal to focusing on diagnosing and treating humans and dogs, controlling vectors, and improving human dwellings, especially in rural areas. Finally, cases of AT in dogs in Brazil distribute heterogeneously in all five regions of the country, with a slight predominance in the Northeast region.

Calcium supply alters aquaporin transcription and enhances water deficit resilience in a Eucalyptus hybrid - Patricia Ramalho de Barros; Samuel Vasconcelos Valadares; Alice Pita-Barbosa; Wagner L. Araújo; Nairam Félix de Barros (Trees, 2026)
Key message Calcium plays a role in modulating aquaporin expression, reducing oxidative stress, preserving chlorophyll content, and maintaining membrane integrity, suggesting it may enhance eucalypt resilience to water restriction. Abstract Drought is a significant abiotic stress that severely impacts the growth and productivity of forests worldwide. This study investigates the role of calcium (Ca 2+ ) supply in modulating aquaporin (AQP) gene expression and mitigating oxidative stress in eucalypt ( Eucalyptus urophylla × Eucalyptus camaldulensis ) under water restriction. Three-month-old eucalypt seedlings were subjected to water restriction, with or without Ca 2+ supplementation. We measured mRNA expression levels of five aquaporin isoforms ( PIP1;2, PIP1;3, PIP2;1, PIP2;2, and PIP2;7 ), chlorophyll content, and markers of oxidative stress [e.g., hydrogen peroxide (H 2 O 2 ), malondialdehyde (MDA), and the activities of catalase (CAT) and superoxide dismutase (SOD)]. Our findings reveal that initial water restriction upregulated the expression of PIP1;2, PIP2;1, PIP2;2, and PIP2;7 in roots, which likely facilitated water uptake and maintained cellular hydration. However, under prolonged water limitation, plants supplemented with Ca 2+ showed downregulation of these PIPs, possibly as a protective mechanism to reduce water loss. In contrast, plants without Ca 2+ exhibited an upregulation of PIP1;2, PIP1;3 , and PIP2;7 under prolonged water deficit. Ca 2+ supplementation also played a crucial role in preserving chlorophyll content and reducing oxidative damage under water limitation. Plants supplemented with Ca 2+ had lower levels of H 2 O 2 and MDA, reduced oxidative damage and membrane permeability, alongside increased CAT activity, which suggests an enhanced oxidative response. Our results provide new insights into how Ca 2+ enhances eucalypt responses to water deprivation, enhancing our understanding of the function of Ca 2+ in drought responses.

Combining spring wheat genotypes with contrasting root traits for a better use of water resources in soil? Evidence from column-scale water stable isotopic experiments - Samuel Le Gall; Dagmar van Dusschoten; Adrian Lattacher; Mona Giraud; Moritz Harings; Paulina Deseano Diaz; Daniel Pflugfelder; Samir Alahmad; Lee Hickey; Ahmet Sircan; Ellen Kandeler; Guillaume Lobet; et al. (Plant and Soil, 2026)
Background and Aims The advantages of genotype mixtures on soil water balance are still poorly understood. We aim to determine the impact of soil water conditions (well-watered or chronic water deficit) on the root water uptake (RWU) of two contrasting root genotypes (“shallow root system” SRS and “deep root system” DRS) and their mixture at the booting stage. We conducted a controlled plant-soil column experiment and quantified daily vertical profiles of the fraction of RWU (fRWU, % cm −1 ), i.e. the relative contribution of RWU normalized by the thickness of each layer. This calculation was achieved by applying Bayesian modelling on non-destructive soil and transpiration water stable isotopic measurements after pulse labelling. We compared these results to the monitored plant soil water status, plant physiology and root traits. The SRS genotype had a higher fRWU than the DRS genotype in the topsoil and vice versa in the subsoil. In the mixture, both genotypes maintained complementary fRWU distributions and, in response to the water deficit, increased their contribution in subsoil by 0.5% cm −1 and decreased their contribution in topsoil by -1.2% cm −1 compared to the monoculture. This study introduces novel observations of root water uptake plasticity, which is determined by genotype root traits, soil water availability, and interactions with neighboring plant root traits. This study highlights the potential of contrasting root traits mixtures to improve their water and nutrient access facing water deficit.

Tetranychus evansi (Tetranychidae) spider mites now a major solanaceous crop pest in Côte d’Ivoire - Emilie Deletre; Chloé Latapie; Alain Migeon; Philippe Auger; Nadia Larpin; Samuel Laboisse; Thibaud Martin (Experimental and Applied Acarology, 2026)
The West African market gardening sector has been plagued in recent decades by phytophagous mite damage to solanaceous crops. Recent studies in Benin and Burkina Faso have confirmed West African outbreaks of red spider mites ( Tetranychus evansi ), a novel mite species native to South America, which has now virtually replaced local species. This study aimed to identify the different mite species infesting solanaceous crops in Côte d’Ivoire, while assessing their abundance and mapping their distributions. Tomato, eggplant and African eggplant crops were sampled along a north-south transect. Structured interviews were conducted to gather information on the crop protection practices. We confirmed the presence of the invasive species, Tetranychus evansi , with higher densities noted in the north, where the hot dry climatic conditions were suitable for its development. Local Tetranychus urticae and Polyphagotarsonemus latus species were not very abundant. The highest spider mite diversity was observed in the Abidjan area, where two new species of the T. urticae group were found. Very few Phytoseiidae predatory mites were present, even in plots that had barely been treated or not at all. Five species were identified: Neoseiulus barkeri , Neoseiulus teke , Amblyseius swirskii , Amblyseius tamatavensis , and Paraphytoseius horrifer. These predatory phytoseiid species seemed unable to control T. evansi populations. According to farmers, abamectin was the only pesticide effective for controlling these pests. To reduce the chemical control intensity, biological control based on the introduction and dissemination of a specific predatory mite such as Phytoseiulus longipes could be considered on a national and regional scale.

The threat of multidrug-resistant microorganisms: active surveillance of key antimicrobial resistant pathogens in 2025 - a report from the INVIFAR network - Adrián Martínez-Meléndez; Elvira Garza-González; María del Rosario Vázquez-Larios; Melissa Garibaldi-Rojas; Bernardo Alfonso Martinez-Guerra; Christian Daniel Mireles-Davalos; Samuel Pavel Escalante-Armenta; José Manuel Feliciano-Guzmán; Daniel Romero-Romero; Maria del Consuelo Velazquez-Acosta; Sandra Quintana-Ponce; Shaúl Ariel Navarro-Lara; et al. (European Journal of Clinical Microbiology & Infectious Diseases, 2026)
Purpose Systematic collection and analysis of antimicrobial resistance data from key bacterial pathogens is essential to contribute to control antimicrobial resistance (AMR). The aim of this work was to survey the drug resistance on clinically relevant organisms stratified according to age, gender, clinical specimens and facilities. Methods Microbiological data were collected from 55 centers across 24 states in Mexico between January 1 and March 31, 2025. Bacterial identification and antimicrobial susceptibility testing were performed at each participating center using locally available methods. Data was processed using WHONET 2025. Isolates obtained from lower respiratory specimens, urine, blood, biopsies and abscesses were analyzed. Carbapenem non-susceptible isolates were further analyzed by PCR for common carbapenemase-encoding genes. Resistance frequencies were compared using the chi-square test. Results A total of 11,290 clinical isolates were analyzed, mostly from urine ( n = 7,149; 63.3%), followed by blood ( n = 1,370; 12.1%). The most prevalent was Escherichia coli ( n = 6,185; 54.8%), followed by Klebsiella pneumoniae ( n = 1,365; 12.1%) and Pseudomonas aeruginosa ( n = 1,110; 9.8%). Resistance to carbapenems in E. coli was higher in respiratory isolates (imipenem: 5.8%, p = 0.016; meropenem: 5.3%, p < 0.001), with 75.9% producing extended-spectrum ß-lactamases (ESBLs). K. pneumoniae had the highest resistance to ampicillin/sulbactam (52.5%, p = 0.028) and sulfamethoxazole/trimethoprim (62.1%, p = 0.014) in blood isolates, and 63.2% were ESBL-producers ( p = 0.001). In P. aeruginosa , urine isolates showed significantly higher resistance to ceftolozane-tazobactam (24.7%, p = 0.008), ceftazidime-avibactam (36.6%, p < 0.001), and meropenem (34.5%, p = 0.009) compared to other clinical specimens included. For A. baumannii , respiratory isolates had 73.6% resistance to meropenem ( p < 0.001). S. aureus from blood showed 25.7% resistance to oxacillin ( p < 0.004). The most frequent carbapenemase genes were bla OXA−48−like in E. coli (26/56, 46.4%), bla NDM for K. pneumoniae (7/17, 41.2%), bla OXA−24 in A. baumannii (79/108, 73.1%) and bla IMP for P. aeruginosa (18/108, 16.7%). Conclusion This surveillance study underscores the elevated levels of antimicrobial resistance, ESBL production, and carbapenemase activity among priority pathogens, including some Enterobacterales , P. aeruginosa , and A. baumannii . These findings emphasize the urgent need to strengthen epidemiologic surveillance programs in Mexican healthcare settings.

Sediment Chemistry Predicts Littoral Methane Emissions - Andrew J. Tanentzap; Samuel G. Woodman; Olesya Kolmakova; Yi Zhang (Ecosystems, 2026)
Methane emissions from the nearshore zones of lakes are relatively large but can vary by several orders of magnitude. This variability may reflect differences in organic matter inputs, particularly the concentration of polyphenolics that alter the electrochemical favourability for methanogenesis and microbial composition and abundance. However, the importance of these different mechanisms relative to each other and to other explanations, such as variability in temperature, remains poorly understood. Here we tested how polyphenolic concentrations and reduction–oxidation potential influenced methane emissions in a comparative study of 19 littoral sites in the UK that varied in organic matter sources and microbial composition. Using path analysis, we compared multiple predictions to explain methane fluxes from polyphenolic concentrations both directly and indirectly via changes to reduction–oxidation conditions and microbial abundance and composition. We found that the prediction that organic matter composition, namely the concentration of polyphenolics, controls methane emissions by changing electrochemical conditions was better supported than predictions involving methanogen and methanotrophic bacteria abundances, methanogen diversity, or other physicochemical conditions. Electrochemical conditions had similarly supported direct and indirect effects mediated by changes in methanogen community composition. Diffusive CH 4 fluxes were estimated to increase by 2.3–10.8 times (95% confidence interval) with increasing polyphenolic concentrations, mostly because they lower reduction–oxidation potentials. Rather than strongly inhibiting methane-producing microorganisms, our results suggest polyphenolics change reduction–oxidation potentials to favour acetoclastic and methylotrophic methanogens. These results help explain conflicting evidence about the responses of methane to organic matter inputs and can improve future predictions of aquatic carbon cycling.

We need to talk about maladaptation - Amy Waananen; Samuel P. Reed; Diele Lobo; Patrick I. Hancock; Jessica J. Hellmann (Climatic Change, 2026)
Climate adaptation actions should help, not harm. However, adaptation efforts can backfire, increasing vulnerability to climate change—a phenomenon known as maladaptation. In this essay, we argue that maladaptation dialogues—inclusive and deliberate conversations about negative consequences and failures of adaptation actions, especially among adaptation professionals—offer unique benefits for advancing climate adaptation practice. When approached deliberately, dialogue can promote shared understanding, learning, and inclusive adaptation processes, helping prevent and respond to climate adaptation gone awry. Further, by integrating conversations about maladaptation into the adaptation cycle, we can enhance adaptation efforts, leading to more innovative and resilient adaptation organizations.

Unravelling the impact of changing rainy seasons on rice production in Southeast Asia: a climate change high-resolution perspective - Mugni Hadi Hariadi; Samuel J. Sutanto; Gerard van der Schrier; Iwan Supit; Dian Nur Ratri; Gert-Jan Steeneveld; Ardhasena Sopaheluwakan; Albert Klein Tank (Climatic Change, 2026)
Southeast Asia is a major contributor to global rice production. Yet, this production is increasingly threatened by climate change, particularly by changes in the rainy season. In this study, We examine the impact of shifts in seasonal cumulative rainfall and characteristics of the rainy season on rice production across Southeast Asia. To achieve this, we utilize the framework of the High-Resolution Model Intercomparison Project (HighResMIP) in conjunction with rice production estimates from the World Food Studies (WOFOST) crop model. Our findings reveal a trend towards drier conditions during the dry season across the region. A decrease in cumulative rainfall is observed during December-January-February in mainland Southeast Asia and the Philippines, with rainfall reductions reaching up to 33% and 15% in certain areas, respectively. In Indonesia, a decrease in rainfall during the June-July-August period was observed across the majority of the region, with some areas experiencing a decrease of up to 48%. This trend is also accompanied by delays in the onset of the rainy season and a reduction in its duration across most of the region. A significant reduction in the rainy season duration, up to 27 days, was found over the southern Philippines, where delays in the onset of the season are followed by an early cessation. The changes in rainfall patterns negatively impact rainfed rice production. Increased rainfall during the second growing season (GS-2) in certain areas of Mainland Southeast Asia and the Philippines enhances rice yields, while reduced rainfall during GS-1 and GS-3 in Java reduces yields. The most substantial effects are observed during GS-3 in Java, with a substantial decrease in yield attributed to reduced rainfall and a shorter rainy season. In addition, rice irrigation simulations indicate that rising temperatures will shorten the growing season, consequently resulting in lower yields. Effective adaptation strategies are crucial to mitigate the decline in rice production. Our analysis suggests that a simple adaptation measure, such as shifting from the C3 photosynthesis type to the C4 photosynthesis crop, may not suffice. Additionally, enhancing and refining agricultural systems is needed to bridge potential yield gaps, emerging as a recommended approach.

Chordae Rupture Alters Tricuspid Valve Leaflet Biomechanics - Julia Clarin; Keyvan A. Khoiy; Samuel D. Salinas; Dipankar Biswas; Kourosh T. Asgarian; Francis Loth; Rouzbeh Amini (Cardiovascular Engineering and Technology, 2026)
Purpose Tricuspid valve chordae tendineae rupture is a valvular lesion that is often overlooked, though is postulated to be more prevalent than currently known. We examined the hemodynamics and biomechanical response of the tricuspid valve leaflets following chordae rupture to understand how acute changes in the post-rupture mechanical environment may contribute to long-term remodeling responses. Methods Porcine valve leaflet deformation was studied in an intact heart in an ex vivo setup using sonomicrometry techniques before and after chordae rupture, which was induced by severing a chordae bundle connected to the septal leaflet. Results Following chordae rupture, pulmonary artery pressure dropped approximately 5 mmHg ( $$p=0.048$$ p = 0.048 ), indicating that valvular regurgitation occurred immediately after rupture. Mean maximum principal stretch of the septal leaflet increased 12% after rupture ( $$p=0.006$$ p = 0.006 ). Conclusion The immediate changes in post-rupture septal leaflet stretches show that chordae tendineae rupture acutely alters the biomechanical environment of the tricuspid valve, which may result in chronic tissue remodeling responses. Non-technical Summary The tricuspid valve is one of the four valves in the heart. Rupture of supporting structures of the tricuspid valve leaflet, known as chordae tendineae, may be more common than previously thought. In this study, we used excised pig hearts to examine how chordae rupture affects valvular function. With our experimental beating heart system, we pumped fluid through the hearts under realistic conditions and measured changes in pressure and leaflet motion before and after chordae rupture. After rupture, we observed a change in pressures and leaflet motion, causing the valve to leak and become less efficient. These changes may influence how the valve functions over time.

Additional description and molecular characterization of Naobranchia lizae (Krøyer, 1863) and Naobranchia variabilis Brian, 1924 (Copepoda: Lernaeopodidae) from the Mexican Pacific - Gerardo Torres-Carrera; Fernando Ruiz-Escobar; Alejandro Oceguera-Figueroa; Samuel Gómez; Francisco N. Morales-Serna (Marine Biodiversity, 2026)
Members of the copepod family Lernaeopodidae are parasites of chondrichthyan and actinopterygian fishes, with the genus Naobranchia Hesse, 1863 being one of the most diverse groups parasitizing the gills of marine fishes. The genus currently comprises 21 species; however, molecular data for most species remain unavailable or poorly validated. In this study, copepod specimens were collected from the gills of Mugil cephalus Linnaeus, 1758 in Teacapán, Sinaloa, and from Aluterus monoceros Linnaeus, 1758 in Puerto Ángel, Oaxaca, along the Mexican coast of the eastern tropical Pacific. Based on morphological examination, these specimens were identified as Naobranchia lizae (Krøyer, 1863) and Naobranchia variabilis Brian, 1924, respectively. Morphological features of both species were documented through detailed drawings and photographs. In addition, a fragment of the mitochondrial cytochrome c oxidase subunit I ( cox 1) and two nuclear ribosomal DNA markers (18S and 28S) were generated for both taxa, representing the first well-documented molecular data for the genus Naobranchia . Phylogenetic analysis of cox 1 placed N . lizae and N . variabilis in the same clade with an unpublished sequence of Naobranchia vermiformis Rangnekar, 1956 (ON023684), forming a well-supported monophyletic group. The genetic distances between species of Naobranchia range from 13 to 19%, consistent with interspecific levels reported for other lernaeopodids. Our findings provide evidence supporting the presence of N . lizae and N . variabilis in the Mexican Pacific, establishing a reliable morphological and molecular reference to support future ecological, biogeographical, and systematic studies of Lernaeopodidae.

Pseudoteratosphaeria supramediana sp. nov. (Teratosphaeriaceae, Mycosphaerellales), a New Foliar Pathogen on Eucalyptus in Indonesia - Nam Q. Pham; Seonju Marincowitz; Brenda D. Wingfield; Pedro W. Crous; Samuel A. Santos; Alvaro Durán; Marthin Tarigan; Michael J. Wingfield (Australasian Plant Pathology, 2026)
The Eucalyptus plantation industry in Indonesia has expanded rapidly during the last few decades. This growth is primarily attributed to the replacement of Acacia mangium , that was severely damaged by diseases. The rapid shift to large-scale monoculture plantations of Eucalyptus has introduced new challenges, particularly the emergence of new disease and pest problems. During routine Eucalyptus disease surveys in Indonesia, symptoms of a new leaf and shoot disease were observed on a single hybrid Eucalyptus grandis × pellita clone in Riau and Kalimantan. Leaf samples were collected, and isolations were made from the disease symptoms. Isolates were identified based on their morphological characteristics and DNA sequence data for seven loci. Phylogenetic analyses of the isolates revealed a novel species of Pseudoteratosphaeria , described here as Pseudoteratosphaeria supramediana sp. nov. A greenhouse pathogenicity test resulted in symptoms similar to those found under field conditions, and the inoculated fungus was consistently reisolated from the resulting lesions. Its appearance in two geographically distinct locations of Indonesia raises the possibility of multiple independent introductions of the pathogen.

Limited human mobility during the Neolithic period in the Meuse and Mons basin in Belgium: multi-element isotopic analysis - IJk van Hattum; Marta Costas-Rodríguez; Kasper Hobin; Prudence Robert; Frank Vanhaecke; Elliot Van Maldegem; Hélène Collet; Pierre Cattelain; Michel Toussaint; Hans Vandendriessche; Samuel Bodé; Pascal Boeckx; et al. (Archaeological and Anthropological Sciences, 2026)
While the introduction of the Neolithic way of life in central Belgium around 5300 BCE is well-documented, the provenance and mobility patterns of Middle to Final Neolithic groups in southern Belgium (Wallonia) remain unclear. This work presents the first multi-element isotopic (strontium, 87 Sr/ 86 Sr; oxygen, δ 18 O; carbon, δ 13 C) data from prehistoric human dental enamel from the region. The study includes a total of 29 individuals, coming from karstic caves in the Meuse basin, the mining complex of Spiennes, and the megalithic tomb of Wéris II. The study also explores the variability of bioavailable strontium ratios in the geologically heterogeneous Meuse basin using modern plants. The analysis of multi-element isotopic data reveals high δ 18 O values and diverse 87 Sr/ 86 Sr ratios. The findings suggest that these individuals likely originated from or spent their childhood in present-day Belgium. Furthermore, the study highlights limited mobility during the Final Neolithic period, characterized by a combination of local residency and potential short-distance mobility or post-mortem movements. Overall, this study provides the first δ 18 O values from ancient human remains in the region and reshapes our understanding of human mobility during the Neolithic in present-day Belgium.

Further Description and First Genetic Characterization of Oswaldofilaria bacillaris (Nematoda: Onchocercidae) Infecting the Pantanal Caiman (Caiman yacare), with Insights into the Phylogeny of Oswaldofilaria - Glória M. C. Lacerda; Gustavo M. do Carmo; Lorena G. Ailán-Choke; Fernando Paiva; Luiz E. R. Tavares; João A. de Araújo-Filho; Samuel C. Ribeiro; Felipe B. Pereira (Acta Parasitologica, 2026)
Purpose Oswaldofilaria bacillaris is the type species of the genus, but its morphology remains little known and partially contradictory. Moreover, there are no genetic data and scanning electron microscopical observations on the species, like in most Oswaldofilaria spp. The phylogenetic relationships among Oswaldofilaria spp. are practically unknown. This study aimed to evaluate the detailed morphology of O . bacillaris , provide its first genetic characterization, and discuss the phylogenetic relationships within Oswaldofilaria . Methods Parasites infecting the body cavity of Caiman yacare in Pantanal wetlands, Mato Grosso do Sul, Brazil, were collected and processed for morphological studies using light and scanning electron microscopy. Genetic characterization was based on partial sequences of 18S and 28S rDNA. A phylogeny was reconstructed based on 28S sequences including all Oswaldofilaria available. Results Nematodes were assigned to O . bacillaris mainly based on the oral opening markedly displaced ventrally. Males had seven pairs of caudal papillae encircling the cloaca, and their two most posterior pairs were hardly visible, which is also characteristic in other congeners. Moreover, a delicate area rugosa previously unreported in the species was observed. Oswaldofilaria bacillaris formed a monophyletic assemblage with the congeners, being sister to O . chabaudi , and O . petersi was basal, these last two parasites of lizards. Conclusion The present findings strengthened the specific diagnosis of O . bacillaris and elucidated the morphological contradictions. The phylogeny reinforced the hypotheses that Oswaldofilaria emerged in lizards and colonized crocodilians by host switch, and reduction in number of caudal papillae in males is a derived feature.

Uncoiling Host–Parasite Interrelationships: Bounded Snail‐Host Flexibility Amid Conserved Trematode Morphology - Taylor M. Fiedor; Samuel N. Messinides; Kyle D. Gustafson (Molecular Ecology, 2026)
Host–parasite communities are shaped by the tension between evolutionary constraints and ecological opportunity. Digenetic trematodes, which rely on snail hosts to produce diverse larval stages, offer a powerful system to test hypotheses about evolutionary conservatism and ecological flexibility with implications for community structure. Across 120 sites spanning three ecoregions, 6.5% of 14,623 snails were infected by trematodes. Sequencing (18S and 28S) from 104 cercariae among 12 morphotypes revealed 22 trematode families concentrated in a few keystone host taxa. Model‐based analyses showed that cercaria morphotypes exhibited nearly perfect phylogenetic signal. In contrast, host use, defined by the snail lineages each trematode infects, evolves under an Ornstein–Uhlenbeck model of stabilizing selection. This asymmetry indicates that cercaria morphotypes are evolutionarily stable relative to host use, which remains flexible but bounded within an adaptive landscape. Our data elucidate complex life cycles, uncovers parasite diversity maintained by keystone host taxa and reveals recurrent ‘evolutionary reunions’, in which distantly related trematodes revisit ancestral snail associations through ecological fitting and adaptations toward common host lineages. Evolutionary reunions help resolve the long‐standing parasite paradox—how parasites remain specialized yet occasionally capture or shift hosts—by demonstrating that host–parasite evolution is not a linear process of continual novelty but a dynamic interplay of constraint, contingency and opportunity. Together, these findings provide a molecular framework linking evolutionary and ecological processes to identify general rules of symbiotic interrelationships, with implications for predicting the origins of emerging diseases, the persistence of coevolutionary networks and biodiversity responses to environmental change.

Dynamic cycling and redox transformations of dissolved organic sulfur in the surface ocean - Molly A. Crotteau; Erin L. McParland; Alexandra A. Phillips; Elizabeth B. Kujawinski; Krista Longnecker; Aaron M. Martinez; Samuel M. Webb; Morgan R. Raven (Limnology and Oceanography, 2026)
The marine dissolved organic sulfur (DOS) pool contains both labile metabolites that are rapidly cycled in the surface ocean and compounds that may persist for thousands of years in the marine environment. Here, we describe the sulfur speciation of marine solid‐phase extracted DOS (DOS SPE ) from the North Atlantic surface ocean, revealing a diversity of oxidation states that include alkyl sulfides, disulfides, aromatics, sulfonates, and sulfate esters. As dissolved organic carbon concentrations decrease with depth in the water column, relative abundances of reduced sulfur species decrease while those of oxidized sulfur species increase, indicating preferential remineralization of reduced organic sulfur (OS) compounds. Although microorganisms are considered to be the origin of a vast majority of marine DOS SPE , the DOS SPE produced by cultures of phototrophs and heterotrophic bacteria is compositionally distinct and 34 S‐enriched relative to environmental DOS SPE . Ultimately, mechanisms spanning different timescales, including microbial reworking, uptake, and photochemical oxidation transform labile DOS in the surface ocean, and may generate recalcitrant compounds that contribute to the long‐lived dissolved organic matter pool. The oxidation states of OS function as powerful tools for tracking the sources, sinks, and transformations of organic matter in complex biogeochemical systems.

Environmental Variability Shapes Life‐History Trade‐Offs Within and Between Populations of a Long‐Lived Seabird - Bertille Mohring; Jonathan R. Potts; Alastair J. Wilson; Denis Réale; Richard A. Phillips; Henri Weimerskirch; Christophe Barbraud; Ashley Bennison; Karine Delord; Andrew G. Wood; Samuel Peroteau; Etienne Rouby; et al. (Ecology Letters, 2026)
Individuals face a trade‐off between allocating resources to reproduction or self‐maintenance, yet the drivers of the existence and strength of such trade‐off have been hard to determine. Environmental conditions are thought to play a crucial role, as long‐lived species are predicted to favour more precautionary life‐history strategies in variable environments. However, empirical evidence remains limited. Using long‐term monitoring of two black‐browed albatross Thalassarche melanophris populations, we investigated variation in life‐history strategies under contrasting environmental conditions, through reproductive senescence. In more variable environments, individuals displayed generally slower life histories (i.e., slow, late‐onset senescence) and greater among‐individual variation in life‐history strategies. Interestingly, earlier and faster reproductive senescence correlated with higher lifetime reproductive success regardless of environmental variability, suggesting that either faster life histories incur higher fitness or successful reproduction accelerates reproductive senescence. These findings reveal how environmental variability shapes life‐history strategies, highlighting potential responses to increasing environmental variability in a changing world.

Fine-scale proximity to offshore wind turbine foundations increases biomass of demersal fish species - Anthony W. J. Bicknell; Samuel Gierhart; Mario Lambrette; Matthew J. Witt (Frontiers in Marine Science, 2026)
Offshore wind turbine fixed-bottom foundations provide artificial hard substrate through the water column that encourages marine flora and fauna to colonise and aggregate around the introduced structures, a well-documented phenomenon known as the ‘artificial reef effect’. The cumulative impact thousands of turbine foundations at multiple offshore sites have on local and regional marine species populations and communities is not fully understood. Knowledge of the extent and magnitude of the reefing effect at a fine scale (single turbines) is a prerequisite to making broader-scale (single or multiple wind farms) predictions of population level and ecosystem changes caused by presence of offshore wind farms. The influence of fine-scale distance (<250 m) to turbine jacket foundations on abundance, biomass and size of demersal fishes was assessed at a northern latitude wind farm. Abundance and biomass of all demersal fishes, flatfish Pleuronectiformes spp. and haddock Melanogrammus aeglefinus were found to have a significant negative relationship with increasing distance from foundations. Haddock were found to aggregate closer to the structures, yet all statistical models predicted a similar magnitude of increase for each group of between ~1.5 and 1.6 times more individuals and biomass at 30 m from the foundations compared to 240 m. The results illustrate that fine-scale proximity to offshore wind fixed foundations has considerable effects on the presence of some demersal fish species. The cumulative or wider ecosystem consequences of these effects are not known, but the further evidence for localised reefing effects can be of strategic interest for optimizing future wind farm project design, included implementation of nature-inclusive measures that could help meet future marine net gain aspirations.

Comparison of Spatial Patterns of Aridity in Argentina Based on Different Climatic Indices and Datasets - Pedro Samuel Blanco; Moira Evelina Doyle (International Journal of Climatology, 2026)
Aridity significantly affects ecosystems, agriculture and water resources. Characterising its spatial patterns is key for designing adaptation and mitigation strategies against advancing desertification, but comparative assessments of how different indices and datasets represent these patterns are still lacking. This study analyses the spatial patterns of aridity in Argentina during 1961–2020 by comparing different climatic indices and datasets. Monthly precipitation and temperature data from observations and gridded datasets—CRU, WORLDCLIM and ERA5—were used. Potential evapotranspiration (PET) was estimated using Thornthwaite, Holdridge and Hargreaves–Samani methods. Aridity indices were calculated at annual and seasonal scales, selected for their frequent use in recent literature and ability to provide complementary perspectives on aridity. The performance of the gridded data was evaluated using various statistical comparison metrics against observations. The results show that aridity indices based on mean temperature or PET, particularly those using the Thornthwaite method, are more consistent in representing climate patterns in Argentina compared to indices based on temperature ranges. On one hand, CRU and WORLDCLIM exhibited similar performance, with relatively low biases, high spatial coherence with observations, and good representation of statistical distributions, while on the other hand, ERA5 showed significant errors in representing climate categories and estimating changes in aridity, especially during summer and in areas with complex topography. These findings highlight the importance of carefully selecting the aridity index and dataset, as this decision affects the representation of aridity patterns and their changes, which are crucial for climate monitoring and decision‐making in regions vulnerable to desertification.

Chronic High-Carbohydrate And High-Fat Diet-Induced Metabolic Syndrome Leads To Adrenal Dysfunction, Altered Dendritic Morphology In Limbic Regions, And Anxiety-Like Behaviors In Male Rats - Samuel Treviño; Estefania Fuentes; Berenice Venegas; Guadalupe Muñoz-Arenas; Rubén A. Vázquez-Roque; Fabián Galindo-Ramírez; Everardo Avelino-Cruz; Gonzalo Flores; Jorge Guevara; Alfonso Díaz (Journal of Molecular Neuroscience, 2026)
Metabolic syndrome (MS) represents a major global health problem affecting a large proportion of the population. The improper management of peripheral carbohydrates and lipids leads to behavioral changes in neurons of the limbic brain. This work studied male rats that received diets high in carbohydrates, lipids, and their combination for ninety days. The study examined how peripheral metabolic changes and hypothalamic-pituitary-adrenal (HPA) axis alterations affect dendritic structure in limbic brain regions, thereby inducing anxiety-related behavioral responses. Our results show that male rats develop MS after consuming diets high in fat, carbohydrates, and their mixture for an extended period. These diets after the normal function of the HPA axis, leading to increased anxiety symptoms and reduced dendritic growth in limbic areas. This is accompanied by increased caspase-3 immunoreactivity and decreased cell viability. Therefore, it is suggested that diets high in carbohydrates or fats are a critical factor that could induce adrenal stress that damages dendrites and accelerates neurodegeneration, resulting in anxiety-related behavioral changes.
