EESC Cooperative Science with the Atlantic States Marine Fisheries Commission
From “blue water” rivers and streams to “green water” marine environments and brackish estuaries in between, EESC and the Atlantic States Marine Fisheries Commission are collaborating to bring together local, regional, and national expertise to provide the science that modern fisheries management demands.

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

Preliminary Research Sheds Light on Proper Analysis and Sample Handling for the Tire-Derived Contaminants 6PPD and 6PPD-quinone
Tire and road wear particles have been shown to cause acute effects to sensitive aquatic animals and degrade their habitats. U.S. Geological Survey (USGS) scientists developed methods to accurately identify aquatic compounds, such as 6PPD and 6PPD-quinone, that can cause acute mortality events in coho salmon (Oncorhynchus kisutch).

New study highlights linkages among land use, water chemistry, and the health of Smallmouth Bass in the Susquehanna River watershed
Contaminants associated with agricultural and developed land uses may negatively affect SMB health and disease resistance in the Susquehanna River watershed.
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.
