Conservation implications of low contemporary connectivity along the Mid‐Atlantic Ridge in hydrothermal vent gastropodsNARA Subscribed
Polymetallic sulfide deposits produced at hydrothermal vent fields are targets for mining exploitation along the Mid‐Atlantic Ridge, threatening the functioning and resilience of vent ecosystems that provide multiple ecosystem services. Knowledge about connectivity between vents will inform conservation practices. The present‐day genetic structure and demographic history of the two vent‐dwelling gastropod species, Lepetodrilus...
Disseminated Salmonella enterica infections represent a severe form of non-typhoidal salmonellosis increasingly complicated by antimicrobial resistance. We describe a case of disseminated non-typhoidal Salmonella in a man presenting with septic shock concerning for a thoracoabdominal endovascular graft infection with involvement of the urinary and respiratory tracts and thoracic skeleton. Hybrid whole-genome sequencing identif...
A Global Review of Bycatch Reduction Technology Assessments: Revealing Gaps in Fisher‐Focused MetricsNARA Subscribed
Global fisheries support livelihoods, food security and economies, but the incidental capture of non‐target species—termed bycatch—remains a key conservation challenge. We compiled peer‐reviewed published studies to assess metrics used to evaluate the effectiveness of bycatch reduction technologies and gear modifications (BRTs) for reducing air‐breathing marine megafauna bycatch in global passive fisheries. We assessed 196 stu...
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...
An Equatorial Hemispheric Barrier Shapes the Diversification of Migratory Belenois ButterfliesNARA Subscribed
Biogeographic barriers are typically considered prominent geographic features that block or severely restrict dispersal and gene flow. However, mating barriers can also emerge within continuous suitable habitats, driven by ecological or behavioural constraints. Migratory insects show an extraordinary capacity to traverse vast geographic ranges, as well as notable landscape features like mountains, deserts and oceans. Yet, thei...
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...
Alternating self-administration sessions of cocaine and heroin impact drug-related motivation and vocalisations in ratsNARA Subscribed
Rationale Animal models of addiction often study changes in motivation after repeated self-administration of a single drug. However, human users frequently consume multiple drugs, potentially altering their motivation and affective response. Objectives This study investigated how individual rats differentially self-administer cocaine and heroin, and whether motivation to take each drug was associated with affective states, as...
Application of fin tissue for nonlethal stable isotope analysis of small-bodied fishesNARA Subscribed
Stable isotopes are commonly used to characterize food web structure and resource use by aquatic organisms. White muscle is generally preferred for stable isotope analysis of fishes. However, obtaining white muscle tissue typically requires lethal take or invasive sampling techniques, which are undesirable for small-bodied species or those of conservation concern. We assessed the use of fish fin as a nonlethal alternative to m...
We formally describe the association of fishes and anthozoans in epipelagic waters, extending this relationship to beyond the benthos. In situ observations and photographs of Aluterus schoepfii , Ariomma regulus , Caranx cf. latus and Brama spp. swimming alongside or holding larval tube anemones (Cerianthidae and Arachnactidae) and larval zoanthids (Sphenopidae) were made during blackwater SCUBA dives off Palm Beach, Florida,...
Teamwork makes the dream work: combining community science and expert-led surveys to study urban plant richness and compositionNARA Subscribed
Maintaining diverse plant communities in cities is critical to meeting conservation goals and supporting human well-being. However, gaps persist in our understanding of the various factors that interact in urban environments to modulate plant richness, composition, and persistence. Elucidating these gaps would inform successful conservation efforts but requires extensive data to capture the many factors that impact ecological...
