Three researchers in EBTJV's network recently published Is now the time? Review of genetic rescue as a conservation tool for brook trout, in the journal Ecology and Evolution.
Jacob Rash, one of the coauthors of the study, and EBTJV's Chairman, offered: “Although genetic rescue holds promise, there is much to consider when evaluating this conservation approach. This paper reviews the strengths and weaknesses of genetic rescue, while encouraging the tool’s robust development through collaboration among those that use it.”

Also noteworthy is that the study's lead author, Shannon White, has been selected as a 2023 recipient of the American Fisheries Society Genetics Section Early Career Award. Shannon works for the USGS Eastern Ecological Research Center, where her work benefits species like Atlantic sturgeon and flathead catfish, in addition to brook trout.

Patterns, drivers, and a predictive model of dam removal cost in the United States (Duda et al. 2023). This manuscript documents the trends and patterns of dam removal cost as part of the Large Dam Removal research collection. It describes two databases that document dam removal cost -- one with 668 removed dams, their total cost, and the presence of 3 dam removal cost driver categories (deconstruction, mitigation, and restoration) and another that has detailed cost breakdowns for 15 dam removals. Regional trends are highlighted as well as a cost model that describes the main drivers of dam removal cost. Co-authors created an R Shiny app that allows users to explore dam removal costs based on dam height, stream characteristics (discharge and watershed area) and project complexity.
Chesapeake Bay rising waters workshop proceedings: This STAC workshop examined current information on drivers and effects of rising water temperatures and sought answers to a critical question: what might the CBP partnership do now–within the scope of its current goals, policies and programs–to actively prevent, mitigate or adapt to some of the adverse consequences?
Chesapeake Bay targeting: A collection of maps and applications that can be used to evaluate watershed restoration and landscape conservation initiatives relative to multiple goals and outcomes of the Chesapeake Bay Watershed Agreement.
