Genomics‐informed management of ex situ populations

Conservation Biology, EarlyView.
Abstract The European Association of Zoos and Aquariums (EAZA) manages insurance populations for hundreds of species through its EAZA ex situ programs (EEPs). EEPs help safeguard against extinction in the wild and provide source populations for genetic rescue programs.

Prospects of multipurpose biomonitoring for fisheries assessment based on environmental nucleic acids

Journal of Fish Biology, EarlyView.
Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.

Predictive evolutionary genomics: principles, validation, and practice

New Phytologist, EarlyView.
Summary Climate change and habitat loss are driving rapid evolutionary responses in populations world‐wide, which creates an urgent need for evolutionary forecasting in conservation and agriculture. Such forecasting can be categorized into three time scales: trait‐based models that use multivariate quantitative genetic equations to project correlated ...

Ecology of reintroduced Rocky Mountain bighorn sheep in Dinosaur National Monument La Ecología de Borrego Cimarron de las Montañas Rocosas Reintroducido en el Monumento Nacional de Dinosaurio

Wildlife Monographs, Volume 223, Issue 1, August 2026.
We synthesized GPS telemetry, genetic, and pathogen data to evaluate metapopulation processes in a reintroduced Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population in Dinosaur National Monument. We estimated subpopulation‐specific abundances and found 4 small subpopulations with high genetic diversity, partial connectivity, and ...

Conservation implications of low contemporary connectivity along the Mid‐Atlantic Ridge in hydrothermal vent gastropods

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract 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.
