Type Studies of Five Phylloporus (Boletaceae) SpeciesNARA Subscribed
Despite notable progress in the systematics of Phylloporus achieved over the past decade, reexamination of type specimens remains essential for further support in the circumscription of the species, improved identification, robust phylogenetic inferences, and a clearer understanding of species diversity and distribution. Here, we present an updated microscopic morphoanatomical analysis of the type specimens of Phylloporus bell...
Contrasting Heatwave Regimes in Dry and Humid Subtropical Mexico: A Station‐Based Probabilistic AssessmentNARA Subscribed
Heatwaves have intensified across many regions due to ongoing warming, leading to significant environmental and societal impacts. The present study characterizes heatwave regimes across two contrasting subtropical regions of Mexico: the arid‐to‐semiarid northwest and the humid tropical Yucatán Peninsula. Using a station‐based percentile framework that enables consistent inter‐regional comparison, we identify marked differences...
Astrocaryum aculeatum fixed oil is effective against dactylogyrideans without compromising gill structure in Colossoma macropomumNARA Subscribed
Dactylogyrideans infect the gills of Colossoma macropomum (tambaqui), causing parasitosis that requires therapeutic intervention. Phytotherapeutics may provide an alternative to chemotherapeutants, which have limited efficacy.This study evaluated the anti-dactylogyridean efficacy of Astrocaryum aculeatum fixed oil on tambaqui, as well as the effects of bath treatments on hematological parameters and gill histopathology. The fi...
Fire frequency differentially affects carbon pools and pyrogenic organic matter in a South African montane grasslandNARA Subscribed
Aims Grasslands are globally important for biodiversity and ecosystem services, including carbon storage, and have coevolved with disturbances such as fire. However, the effects of fire on soil carbon storage in southern African grasslands remain poorly understood. We investigated how fire frequency (annual, biennial, quinquennial, and infrequent) influences the distribution of soil organic carbon (SOC) pools in a 40-year burn...
Human‐induced high densities of large wild herbivores may pose a threat to natural ecosystems, modifying biodiversity and ecosystem functioning. Although the negative impacts on individual taxa and processes are well documented, a comprehensive understanding of how ecosystem integrity responds to high herbivore densities remains limited. This study addresses this gap through an extensive herbivore‐density manipulation experime...
The novelty of this study lies in the integration of fermentation in a magnetically stabilized fluidized bed bioreactor with S. cerevisiae supported on calcium alginate with magnetic particles and using levoglucosan, a pyrolytic sugar from sugarcane bagasse, as a substrate for bioethanol production. Sugarcane bagasse was pretreated with acetic acid to remove alkali/alkaline earth metals (AAEMs) aiming to intensify levoglucosan...
Interpretable deep learning reveals spatiotemporal MRI features of brain aging that align with neurodegenerationNARA Subscribed
Cortical thinning and atrophy are hallmarks of brain aging that have been characterized using magnetic resonance imaging (MRI). Brain aging involves many neuroanatomic features whose effects on brain structure remain unexplored. To address this challenge, we trained interpretable deep neural networks (DNNs) to estimate brain age (BA) from T 1 -weighted ( T 1 w) MRI. By identifying MRI features unapparent to humans, DNNs can fi...
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...
Diagnosing scaling bottlenecks in 10 community conservation initiatives in southern and eastern AfricaNARA Subscribed
Scaling area‐based conservation, including initiatives led or comanaged by Indigenous Peoples and local communities, is a flagship goal of the Kunming‐Montreal Global Biodiversity Framework. Conservationists often aspire to scale initiatives, but this is rarely achieved in practice. Identifying and addressing factors that limit initiative adoption (i.e., bottlenecks) could improve scaling strategies. We used insightsfrom 84 ex...
Alzheimer’s disease (AD) disproportionately affects women and carriers of the apolipoprotein E ε4 allele (APOE4), yet little is known about how sex and APOE interact to influence white matter (WM) integrity during disease progression. We integrated diffusion MRI and matched blood transcriptomic data to investigate these interactions and their underlying biological mechanisms. WM microstructure was quantified using diffusion te...
The initial development of the digestive system and the expression of the genes that codify the proteolytic enzymes – pepsin and trypsin – and the peptide transporter – pept1 – were investigated in the larvae of the tambaqui, Colossoma macropomum . The larvae were raised in recirculating aquaculture system (27.99 ± 0.05°C) until 36 Days After Hatching (DAH), being then fed on Artemia nauplii up to 21 DAH, when pelleted feed (5...
