Genetic stock identification (GSI) estimates stock proportions and individual assignments
through comparison of genetic markers with reference populations. It is used widely in …

Over the last few decades, measurements of light stable isotope ratios have been
increasingly used to answer questions across physiology, biology, ecology, and …

Species that migrate long distances or between distinct habitats—for example, anadromous
or catadromous fish—experience the consequences of climate change in each habitat and …

Protecting habitats for imperiled species is central to conservation efforts. However, for
migratory species, identifying juvenile habitats that confer success requires tracking …

Accurate taxonomic identification is foundational for effective species monitoring and
management. When visual identifications are infeasible or inaccurate, genetic approaches …

Biocomplexity contributes to asynchronous population dynamics, buffering stock complexes
in temporally variable environments, a phenomenon referred to as a “portfolio effect”. We …

Fisheries bycatch is a global problem, and the ability to avoid incidental catch of non-target
species is important to fishermen, managers, and conservationists. In areas with sufficient …

Ocean fisheries often target and catch aggregations comprising multiple populations or
groups of a given species. Chinook salmon (Oncorhynchus tshawytscha) originating from …

Global loss of biodiversity has placed new urgency on the need to understand factors
regulating species response to rapid environmental change. While specialists are often less …

Fish face many anthropogenic stressors. Authorities in marine, estuarine, and freshwater
realms often share interdependent fisheries management goals, but address singular …
