There is a long research history addressing olfactory imprinting, natal homing, and non-natal
straying by anadromous salmon and trout (Salmonidae). In undisturbed populations, adult …

Chemical analysis of calcified structures continues to flourish, as analytical and
technological advances enable researchers to tap into trace elements and isotopes taken up …

Chemical constituents in otoliths have become a valuable tool for fish ecologists seeking to
reconstruct migratory patterns and life‐history diversity in a wide range of species …

Otolith chemistry is often useful for tracking provenance of fishes, as well as examining
migration histories. Whereas elements such as strontium and barium correlate well with …

Selective mortality during early life history stages can have significant population-level
consequences, yet critical periods when selective mortality occurs, the strength of selection …

Assessing the role of local populations in a landscape context has become increasingly
important in the fields of conservation biology and ecology. A growing number of studies …

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

The loss of genetic and life history diversity has been documented across many taxonomic
groups, and is considered a leading cause of increased extinction risk. Juvenile salmon …

The California Central Valley contains the southernmost native populations of Chinook
Salmon Oncorhynchus tshawytscha, which inhabit a highly variable, anthropogenically …

Here we ask whether straying differs among species, life history types, and populations of
adult hatchery-produced Pacific salmon (Oncorhynchus spp.) and steelhead (Oncorhynchus …
