Discovery of Out-of-basin Introgression in Pettit Lake Sockeye Salmon: Management Implications for Native Genetics

Population level biodiversity is critical for preventing extinction in endangered populations. Oncorhynchus nerka in the Snake River Basin have exhibited diversity losses as populations have become extirpated and federally listed as endangered. Efforts to restore O. nerka in the...

Whose Kids Did You Eat? Genetic Identification of Species and Parents of Larval Lampreys in Fish Predator Guts

The Pacific Lamprey Entosphenus tridentatus is an important species both ecologically and culturally, but their population numbers and range have declined severely in the past several decades in the Columbia Basin. In freshwater ecosystems, larval lampreys are candidate prey species for...

Distribution of Genetic Variation Underlying Adult Migration Timing in Steelhead of the Columbia River Basin

Fish migrations are energetically costly, especially when moving between freshwater and saltwater, but are a viable strategy for Pacific salmon and trout (Oncorhynchus spp.) due to the advantageous resources available at various life stages. Anadromous steelhead (O. mykiss) migrate...
