Human impacts driving loss of spring-run Chinook

Analysis of changes in Chinook genetic structure over time indicates that human impacts on watersheds have induced a shift in the relative frequency of spring-run and fall-run alleles at a single locus, with negative implications for Chinook phenotypic variation and adaptive potential…

Demographic structure of Chinook populations is shifting

The demographic structure of anadromous salmon populations is controlled by complex interactions among numerous biotic and abiotic factors, including ocean and climatic conditions, predator–prey dynamics, interspecific competition, hatchery production, and fisheries practices…
