Baleen Whale Occurrence in the Waters Off Virginia and North Carolina, U.S.A. From 2001 to 2019NARA Subscribed
Eighteen years of visual survey and strandings data were used to describe baleen whale occurrence along the continental shelf of Virginia and North Carolina, U.S.A. This region experiences heavy anthropogenic use, which poses risks for mortality and injury to baleen whales. Between 2001 and 2019, six species of baleen whales were recorded, and whales occurred year‐round. The total number of (on‐ and off‐effort) sightings and s...
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...
Endocannabinoid response to social stress in chronic non-medical prescription opioid usersNARA Subscribed
Rationale The ongoing global opioid crisis underscores the need to better understand the neurobiological mechanisms underlying opioid use disorder (OUD). Stress is a key risk factor for developing and maintaining OUD. While animal models report that the endocannabinoid system (ECS) plays a modulatory role in stress response, alterations of ECS stress reactivity in individuals with OUD have yet to be studied. Objectives Here, w...
Geologic History Explains Freshwater Fish Species Richness Across the Conterminous USANARA Subscribed
Aim Freshwater fishes comprise over 20% of vertebrate biodiversity despite occupying Time Period 2008–2019. Location Conterminous United States (USA). Major Taxa Freshwater fishes. Methods We analysed native species richness from a spatially representative survey of 5321 fish assemblages at 3609 sites. Geologic history was determined from surrogates of tectonic activity, glaciation, sea levels and river capture over the last 6...
Aim The urgency for remote, reliable and scalable biodiversity monitoring amidst mounting human pressures on ecosystems has sparked worldwide interest in Passive Acoustic Monitoring (PAM), which can track life underwater and on land. However, we lack a unified methodology to report this sampling effort and a comprehensive overview of PAM coverage to gauge its potential as a global research and monitoring tool. To address this...
Migratory Birds Advance Spring Arrival and Egg‐Laying in the Arctic, Mostly by Travelling FasterNARA Subscribed
In the current warming climate, many organisms in seasonal environments advance their timing of reproduction to benefit from resource peaks earlier in spring. For migrants, the potential to advance reproduction may be constrained by their migration strategies, notably their ability to advance arrival at the breeding grounds. Recent studies show various changes in migration strategies, including wintering closer to the breeding...
Animals within social groups respond to costs and benefits of sociality by adjusting the proportion of time they spend in close proximity to other individuals in the group (cohesion). Variation in cohesion between individuals, in turn, shapes important group‐level processes such as subgroup formation and fission–fusion dynamics. Although critical to animal sociality, a comprehensive understanding of the factors influencing coh...
Dominance and rarity in tree communities across the globe: Patterns, predictors and threatsNARA Subscribed
Aim Ecological and anthropogenic factors shift the abundances of dominant and rare tree species within local forest communities, thus affecting species composition and ecosystem functioning. To inform forest and conservation management it is important to understand the drivers of dominance and rarity in local tree communities. We answer the following research questions: (1) What are the patterns of dominance and rarity in tree...
