Declines in brook trout abundance linked to atmospheric warming in Maryland, USA

Salmonid fishes provide an important indicator of climate change given their reliance on cold water. We evaluated temporal changes in the density of stream-dwelling brook trout (Salvelinus fontinalis) from surveys conducted over a 36-year period (1988–2023) by the Maryland Department of Natural Resources in Eastern North America. Nonparametric trend analyses revealed decreasing densities of adult

Brodifacoum isomer formulations with potentially lower risk to non-target wildlife

Anticoagulant rodenticides (ARs) have a long history of successful use in controlling vertebrate pest and invasive species. Despite regulatory efforts to mitigate risk, non-target wildlife may be unintentionally exposed to ARs through various trophic pathways, and depending on dose, exposure can result in adverse effects and mortality. Second-generation ARs (SGARs) are mixtures of cis- and trans-d

Parasite abundance-occupancy relationships across biogeographic regions: Joint effects of niche breadth, host availability and climate

Changing biodiversity and environmental conditions may allow multi-host pathogens to spread among host species and affect prevalence. There are several widely acknowledged theories about mechanisms that may influence variation in pathogen prevalence, including the controversially debated dilution effect and abundance-occupancy relationship hypotheses. Here, we explore such abundance-occupancy rela

Developing a Process for Listing Injurious Wildlife Species

This project will develop a transparent process for prioritizing species for listing as injurious, likely to cause damage or harm, under the Lacey Act. Building upon previously developed "horizon scan" and "watchlist" products, this process will identify potentially invasive species that present the greatest risk to lands, waters, and other assets managed by the U.S. Department of the Interior.

Passage, Migration and Critical Habitat of Atlantic (Acipenser oxyrhinchus oxyrhinchus) and Shortnose (Acipenser brevirostrum) Sturgeons in New England Waters

USGS scientists are studying the passage, migration and critical habitat of the Atlantic ( Acipenser oxyrhinchus oxyrhinchus ) and shortnose ( Acipenser brevirostrum ) sturgeon in New England waters to provide managers with population-specific details upon which effective steps can be taken to protect these endangered species.
