Day-to-day variability and method agreement of sweat sodium concentration during pilocarpine iontophoresis and exerciseNARA Subscribed
Purpose Sweat sodium testing is increasingly used to estimate electrolyte losses during exercise; however, the reliability of sweat sodium assessment and the influence of methodological factors remain unclear. We evaluated the day-to-day variability and agreement between common sweat induction, collection, and analytical approaches, including pilocarpine iontophoresis and exercise-induced sweating. Methods Twenty physically ac...
An experimental approach to assess the combined effects of multiple stressors on a large vertebrate speciesNARA Subscribed
The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure. The population of bottlenose dolphins in Barataria Bay, Louisiana, experienced long...
Microplastics have been identified in hundreds of species, with evidence of trophic transfer via contaminated prey. Sarasota Bay common bottlenose dolphins ( Tursiops truncatus ) serve as sentinels of coastal pollution, including plastics and chemical plasticizers. Previous research confirmed microplastic ingestion in these dolphins (100.0%, n = 7) and extensive contamination in 11 common prey species (96.5%, n = 86). This stu...
Whole genome resequencing data provide high-resolution conservation insights into population structure and life historyNARA Subscribed
Whole genome resequencing can be a powerful tool for uncovering biological insights and quantifying population genomic metrics relevant to conservation. These insights have the potential to be most profound in secretive or elusive species that are understudied but whose populations may be waning. The western chicken turtle ( Deirochelys reticularia miaria ) is one such example where conservationists are concerned about reporte...
Literature reviews have become increasingly prominent in scientific discourse; however, few have critically examined the geographic distribution of research, particularly in the field of biometeorology, where studies remain disproportionately concentrated in the Global North. Building on previous regional reviews and special issues, this paper critically examines geographic disparities in publication trends, authorship, and me...
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...
IND-enabling preclinical studies of [11C]COU, a trapped metabolite PET radiotracer for monoamine oxidase-BNARA Subscribed
[ 11 C]COU is a trapped metabolite radiotracer for in vivo analysis of Monoamine Oxidase B activity using positron emission tomography (PET) imaging. [ 11 C]COU has the potential to quantify astrocytosis in the early stages of Alzheimer’s disease, providing an earlier marker of disease than currently available for staging disease progression. Prior preclinical studies have demonstrated the efficacy of this radiotracer in precl...
Muscle fat infiltration (i.e., myosteatosis) is an important index of muscle health and pathology in disease states, such as chronic liver disease (CLD). However, it is unknown whether myosteatosis differs due to anatomical location. Further, the mechanistic implications of divergent intermuscular adipose tissue (IMAT) deposition remain unknown in patients with CLD. Thirty-three patients with CLD (55.0 ± 10.5 years) and 17 hea...
The Greatest Extinction Event in 66 Million Years? Contextualising Anthropogenic ExtinctionsNARA Subscribed
Biological communities are changing rapidly in response to human activities, with the high rate of vertebrate species extinction leading many to propose that we are in the midst of a sixth mass extinction event. Five past mass extinction events have commonly been identified across the Phanerozoic, with the last occurring at the end of the Cretaceous, 66 million years ago (Ma). However, life on Earth has always changed and evol...
Several legal acts mandate that management agencies regularly assess biological populations. For species with distinct markings, these assessments can be conducted noninvasively via capture‐recapture and photographic identification (photo‐ID), which involves processing considerable quantities of photographic data. To ease this burden, agencies increasingly rely on automated identification (ID) algorithms. Identification algori...
Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic accuracy of the records, as well as the metadata. Moreover, we now provide an R packag...
Remotely Sensed Fire Heterogeneity and Biomass Recovery Predicts Empirical Biodiversity ResponsesNARA Subscribed
Aim To compare field‐based evidence of plant and animal responses to fire with remotely sensed signals of fire heterogeneity and post‐fire biomass recovery. Location South‐eastern Australia; New South Wales. Time Period 2019–2022. Major Taxa Studied A total of 982 species of plants and animals, in eight taxonomic groups: amphibians, birds, fish, insects, mammals, molluscs, plants and reptiles. Methods We collated 545,223 plant...
Evaluating the relationship between heat-related illness and cooling center location in VirginiaNARA Subscribed
Extreme heat contributes to adverse health outcomes and public cooling centers are often used as both a heat-health mitigation and management strategy to protect public health during extreme heat events. While the presence of a cooling center should theoretically improve heat-health outcomes in the surrounding community, there are no quantitative studies evaluating this relationship. Using heat-related emergency department and...
