Altered hippocampal lipid profile underlies anxiety-like behavior secondary to mild traumatic brain injuryNARA Subscribed
Traumatic brain injury (TBI) remains a major cause of neurological morbidity worldwide, and mild TBI (mTBI) is frequently associated with emotional disturbances, including anxiety-like behavior. Although classical mechanisms of secondary injury have been extensively characterized, metabolic alterations, particularly those involving cerebral lipid homeostasis, remain incompletely defined. Given the structural and regulatory rol...
A practical guide to investigating biomolecular condensates: a comment from the plant communityNARA Subscribed
Biomolecular condensates formed through phase separation have emerged as a central principle of cellular organization, enabling the dynamic regulation of gene expression, signaling, metabolism, and stress responses. While early conceptual advances in condensate biology have largely originated from animal and in vitro systems, plant cells present a unique set of biological and technical challenges, including rigid cell walls, t...
Aim We investigate the distribution of dispersal modes — endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and dispersal agents (e.g., the main vectors moving seeds). We expected climate to be the mai...
Ageing in Honeybees: Telomere Length Is Driven by Climate and Resource Availability Rather Than Urbanisation or PollutionNARA Subscribed
Understanding how biodiversity responds to human‐caused environmental change represents a major scientific challenge. Among the biological processes underlying these responses, ageing plays a critical role by shaping individual life histories and, ultimately, demographic dynamics. Telomeres, the repetitive nucleotide sequences at the ends of linear chromosomes, are widely used biomarkers of ageing, as their length can be shape...
Large brown algae known as kelp cover extensive areas of Arctic coastlines and can form underwater forests that support diverse faunal communities. In many ice-scoured environments, where shallow subtidal habitats are structurally simplified, kelp may act as the primary foundation species, yet their ecological role across Arctic seascapes remains poorly resolved. Using baited cameras, diver surveys, habitat mapping, and satell...
Influence of maternal or neonatal Vitamin A injection on calf performance and muscle transcriptomics in the cow-calf phaseNARA Subscribed
This study investigated the effects of vitamin A (VA) injection on growth performance, muscle development, and skeletal muscle transcriptomics in calves during the cow-calf phase. Pregnant cows at 250 days of gestation were randomly assigned to one of three treatments: control (CON; no VA injection), VA injection in cows at 250 d of gestation (VAcow), or VA injections in calves at birth and 60 days of age (VAcalf). Calves were...
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
Characterisation of the Exceptional Heatwave Conditions Observed in Brazil During the Record‐Hot Years of 2024 and 2025NARA Subscribed
The intense heatwaves of 2024 and the summer of 2025 underscored Brazil's vulnerability to climate change and extreme weather events. Our results show that 2024 recorded a higher number of hot spells, particularly in subtropical Brazil, while in 2023 the intensity of heatwaves was greater. During the summer of 2025, air temperatures in large parts of southern Brazil exceeded 40°C, reflecting the extreme heatwave conditions in...
Local and Landscape‐Level Environmental Conditions Drive Habitat Selection Across Terrestrial Mammal SpeciesNARA Subscribed
Aim Animal movements are a fundamental process affecting communities and ecosystems. Quantifying habitat selection across species and habitats is key for understanding how animals respond to environmental change. Currently, we lack comparative studies that examine how habitat selection varies across species traits and landscapes. We aim to quantify global patterns of habitat selection to help understand the fundamental drivers...
