Genetic analyses of coastal Oncorhynchus mykiss, commonly known as steelhead/rainbow trout, at the southern extreme of their geographic range in California are used to evaluate ancestry and genetic relationships of populations both above and below large dams. Juvenile fish from 20 locations and strains of rainbow trout commonly planted in reservoirs in the five study basins were evaluated at 24 microsatellite loci. Phylogeographic trees and analysis of molecular variance demonstrated that… 
Population genetic structure and ancestry of steelhead/rainbow trout (Oncorhynchus mykiss) at the extreme southern edge of their range in North America
TLDR
This study elucidates the geographic distribution of native trout populations in this region, and serves as a baseline for evaluating the impacts of hatchery trout on native O. mykiss populations and the success of steelhead conservation and recovery efforts.
Population Structure of Steelhead in Coastal California
AbstractSteelhead Oncorhynchus mykiss are the most widespread of the Pacific salmonids Oncorhynchus spp. and are found in nearly all basins within their native range around the northern Pacific Rim.
Genetic Structure of Pacific Trout at the Extreme Southern End of Their Native Range
Salmonid fishes are cold water piscivores with a native distribution spanning nearly the entire temperate and subarctic northern hemisphere. Trout in the genus Oncorhynchus are the most widespread
Landscape factors affect the genetic population structure of Oncorhynchus mykiss populations in Hood Canal, Washington
TLDR
It was found that samples from within a river system were more genetically similar to each other regardless of life history type or sampling location than they were to similar types from other rivers.
Influences of Habitat and Hybridization on the Genetic Structure of Redband Trout in the Upper Snake River Basin, Idaho
TLDR
The genetic structure of redband trout Oncorhynchus mykiss gairdnerii in the upper Snake River basin was investigated at various scales using 13 microsatellite loci, finding a significant inverse relationship between the degree of genetic differentiation and the level of allelic diversity.
Parallel evolution of the summer steelhead ecotype in multiple populations from Oregon and Northern California
TLDR
Patterns support the hypothesis that the summer-run steelhead ecotype has repeatedly evolved through parallel evolution in multiple river basins, and inform management efforts for these ecotypes and improve the understanding of the role of adaptive genetic variation in conservation.
Dam trout: Genetic variability in Oncorhynchus mykiss above and below barriers in three Columbia River systems prior to restoring migrational access
Restoration of access to lost habitat for threatened and endangered fishes above currently impassable dams represents a major undertaking. Biological monitoring is critical to understand the dynamics
You Can't Unscramble an Egg: Population Genetic Structure of Oncorhynchus mykiss in the California Central Valley Inferred from Combined Microsatellite and Single Nucleotide Polymorphism Data
TLDR
The results demonstrate that the ancestral population genetic structure that existed among Central Valley tributaries has been significantly altered in contemporary populations, and future conservation, restoration, and mitigation efforts should take this into account when working to meet recovery planning goals.
Genetic Characterization of Oncorhynchus mykiss Prior to Dam Removal with Implications for Recolonization of the Elwha River Watershed, Washington
TLDR
Collection of resident Rainbow Trout from the upper portion of the basin were distinguished by lower estimates of genetic varia...
Ancestry and adaptive evolution of anadromous, resident, and adfluvial rainbow trout (Oncorhynchus mykiss) in the San Francisco bay area: application of adaptive genomic variation to conservation in a highly impacted landscape
TLDR
The evolutionary relationships of San Francisco Bay Area steelhead/rainbow trout (Oncorhynchus mykiss) populations are determined and it is demonstrated that ecological conditions in novel habitats above barriers to anadromy influence life‐history evolution.

Population structure and genetic diversity of trout (Oncorhynchus mykiss) above and below natural and man-made barriers in the Russian River, California
TLDR
Genetic variation of trout in the species Oncorhynchus mykiss is examined at 22 microsatellite loci from 20 sites in the Russian River basin in central California to assess relative patterns of genetic structure and variation in fish from above and below both natural and man-made barriers.
Population genetics of steelhead (Oncorhynchus mykiss) in the Klamath River
TLDR
Populations in the lower Klamath region, below the confluence with the Trinity River, consistently clustered together in phylogeographic analyses and had patterns of genetic diversity that suggest reduced gene flow between these sites and sites above the confluent.

Discriminating coho salmon (Oncorhynchus kisutch) populations within the Fraser River, British Columbia, using microsatellite DNA markers
TLDR
Three microsatellite DNA loci were used to examine genetic variation among 16 coho salmon populations within the Fraser River drainage system, in British Columbia, Canada, and show promise as technically simple and highly informative genetic markers for coho Salmon population management.
Gene Flow and Genetic Differentiation among California Coastal Rainbow Trout Populations
TLDR
Present levels of genetic variability and estimates of historical rates of gene flow were obtained by analyses of allele frequency data from 31 California coastal rainbow trout populations, indicating higher than seen in most salmonid species and a weak relationship between geographic proximity of populations and genetic identity.

TLDR
The authors describe the isolation, the polymerase chain reaction conditions, and characterize the cross-species amplification of 17 microsatellite loci in six species of salmonids, finding 14 of these loci are polymorphic in fall-run chinook from the San Joaquin River drainage.
LANDSCAPE STRUCTURE AND HIERARCHICAL GENETIC DIVERSITY IN THE BROOK CHARR, SALVELINUS FONTINALIS
TLDR
Evidence is provided for the role of contemporary landscape features in shaping the observed pattern of genetic diversity at smaller geographic scales (within and among populations within river drainage) and for the increasing evidence for nonequilibrium conditions between drift and migration in a wide array of animal taxa.
