Genomic Insights into a New Burkholderia cenocepacia Sequence Type Linked to Cepacia Syndrome in Cystic FibrosisNARA Subscribed
Burkholderia cenocepacia is an important pathogen in cystic fibrosis (CF) patients, responsible for chronic lung infections and, in severe cases, cepacia syndrome (CS), characterized by necrotizing pneumonia, bacteremia, and high mortality. Epidemic lineages, such as B. cenocepacia J2315 (ET12) and ST32, are highly transmissible and frequently associated with CS. In this study, five B. cenocepacia isolates recovered from sputu...
Coral-dwelling Caribbean gobies exhibit distinct skin microbiota compared to other sympatric speciesNARA Subscribed
Microbial communities fundamentally shape ecosystem function and biodiversity across all biological systems through complex dynamics. In coral reef ecosystems, understanding the dynamics of these microbial communities has become critical for predicting reef responses to environmental stressors. Fish skin microbiota are highly susceptible to environmental changes and may vary significantly across species and geographic location...
Structure–activity relationship of synthetic cathinones: integrated in silico, in vitro, and in vivo studies of α-PiHP analoguesNARA Subscribed
Synthetic cathinones represent the main group of emerging psychostimulants consumed worldwide. Structural modifications of these compounds have led to pyrovalerones, potent dopamine transporter (DAT) inhibitors associated with high abuse liability. Among them, α-pyrrolidinoisohexanophenone (α-PiHP) became the most seized pyrovalerone in the European Union in 2023. Novel analogues have rapidly appeared, yet their neuropharmacol...
Planktonic response to pulse or continuous inorganic nutrient inputs: temporal variations and monitoring implicationsNARA Subscribed
Coastal lagoons are dynamic systems where the mode of nutrient input, continuous or pulsed, or a combination, can significantly affect plankton community structure and function. We conducted a spring field microcosm experiment in a Mediterranean lagoon to evaluate how three nutrient delivery regimes influence planktonic dynamics, using biomass measurements and extracellular enzyme activity (EEA) as functional indicators. Conti...
Coccolithophores are important components of marine phytoplankton and are found to be useful indicators of the environmental conditions of the upper water column. In this study, we investigate coccolithophore abundance and composition in the Cretan Sea and South Cretan area (Eastern Mediterranean), and their relation to prevailing hydrodynamic conditions during late February/early March 2019. Results showed that total coccolit...
Connection over creation: hydrological connectivity drives post-restoration community assembly in coastal pondsNARA Subscribed
Evaluations of wetland restoration have often focussed on the role that dispersal, environmental filters and/or spatial features play in new habitats. Success has generally been measured by comparing new habitats with reference sites. However, in coastal ponds, hydrological connectivity can determine environmental constraints as it can influence salinity, nutrient concentration, and connectivity strength. Based on these premis...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
The role of pondscapes in supporting identitiesNARA Subscribed
This study investigates how pondscapes, networks of ponds, and their surrounding environments contribute to supporting identities across diverse cultural contexts. Supporting identities is a non-material Nature’s Contribution to People referring to people’s sense of place, belonging and connection to nature. We draw on data on landscape features from 17 pondscapes across eight countries in Europe and South America, along with...
Community response in highly dynamic ecosystems: the case of zooplankton from Mediterranean coastal pondsNARA Subscribed
The inherent nature of coastal ponds and their small size make them highly dynamic ecosystems, with great variations in their environmental conditions, such as changes in conductivity (due to sea storms or freshwater inputs), water level, or dissolved oxygen (DO) concentration. Because of these frequent fluctuations, aquatic communities are generally adapted to them, which often hinders the detection of the effects of disturba...
Phytoplankton enhances the flocculation of suspended particulate matter in a turbid estuaryNARA Subscribed
Over the past decades, improvements in water quality—particularly increased oxygen and reduced nitrogen concentrations—have led to changes in phytoplankton biomass and community composition in the Schelde estuary, a macrotidal estuary in Belgium/SW Netherlands. We argue that these changes have affected SPM dynamics by modifying floc stability and size. Seasonal and spatial variability in SPM flocculation dynamics were examined...
Inorganic nutrient input effects and severity of disturbance in zooplankton community structureNARA Subscribed
Mediterranean coastal lagoons are increasingly affected by nutrient enrichment from both natural and anthropogenic sources. While most studies focus on total nutrient loads, little is known about how the mode of nutrient delivery, pulsed or continuous, affects plankton community dynamics. This study aimed to experimentally test how different nutrient input regimes influence zooplankton community structure and plankton biomass...
