Evidence for the Genetic Basis and Epistatic Interactions Underlying Ocean- and River-maturing Ecotypes of Pacific Lamprey (Entosphenus tridentatus) Returning to the Klamath River, California
Surveys of genomic variation have improved our understanding of the relationship between fitness-related phenotypes and their underlying genetic basis. In some cases single large-effect genes have been found to underlie important traits; however, complex traits are expected to be under polygenic...

Relating Spatial Patterns of Stream Metabolism to Distributions of Juveniles Salmonids at the River Network Scale
Understanding the factors that drive spatial patterns in stream ecosystem processes and the distribution of aquatic biota is important to effective management of these systems and the conservation of biota at the network scale. In this study, we conducted field surveys throughout an extensive river...

Maintaining a Wild Phenotype in a Conservation Hatchery Program for Chinook Salmon: The Effect of Managed Breeding on Early Male Maturation
In many salmonid species, age and size at maturation is plastic and influenced by the interaction between genetic and environmental factors. Hatchery reared salmon often mature at an earlier age and smaller size than wild fish. Modern salmon conservation efforts have focused on managing the level of...

Upstream Migration Timing of Columbia Basin Chinook and Sockeye Salmon and Steelhead in 2017
Between April 19 and October 18, 2017, we sampled Chinook (Oncorhynchus tshawytscha) and Sockeye (Oncorhynchus nerka) salmon as well as steelhead (Oncorhynchus mykiss) at the Bonneville Dam Adult Fish Facility (AFF). Fish were measured for fork length, scales were...
