Population Structure and History of Steelhead Trout in California

  author={John Carlos Garza and Libby Gilbert-Horvath and Joe M. Anderson and Thomas D. Williams and Brian C. Spence and Heidi E. Fish},
Steelhead trout (Oncorhynchus mykiss) are the most widespread of the anadromous salmonids. In the western continental United States, 14 Evolutionarily Significant Units (ESUs) have been delineated on the basis of genetic, geographic and ecological variation. Of these 14 western ESUs, 11 have been listed as protected under the US Endangered Species Act (ESA). In California, there are six ESUs, 5 on the coast and 1 in the Central Valley. All but the Klamath Mountain Province ESU is listed, with… 

Figures and Tables from this paper

Population genetics of steelhead (Oncorhynchus mykiss) in the Klamath River
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.
Population genetic structure and ancestry of Oncorhynchus mykiss populations above and below dams in south-central California
No genetic basis was found for the division of populations from this region into two distinct biological groups, contrary to current classification under the US and California Endangered Species Acts.
Over the falls? Rapid evolution of ecotypic differentiation in steelhead/rainbow trout (Oncorhynchus mykiss).
It is concluded that the resident population above one barrier, Big Creek Falls, is the result of a recent anthropogenic introduction from the anadromous population of O. mykiss below the falls, supporting a hypothesis of rapid evolution of a purely resident life history in the above-barrier population in response to strong selection against downstream movement.
Population structure and genetic diversity of trout (Oncorhynchus mykiss) above and below natural and man-made barriers in the Russian River, California
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.
Subpopulation structure of steelhead trout (Oncorhynchus mykiss) in the Middle Fork Eel River as determined by microsatellite DNA polymorphisms
Kinship and family structure, as estimated by the relatedness coefficient (rxy), effectively explained observed genetic disequilibrium, suggesting that the summer life-history phenotype has a heritable component.
Disruption of historical patterns of isolation by distance in coastal steelhead
It is suggested that current relationships among modern steelhead populations are no longer reflective of natural migratory pathways, demonstrating the critical role of migration in maintaining population relationships of threatened species and highlighting the importance of natural history museums in providing historical baseline information.
Contrasts in Habitat Characteristics and Life History Patterns of Oncorhynchus mykiss in California's Central Coast and Central Valley
Fish growth rates of CV fish were up to 10 times faster than those of fish on the coast and had the opposite seasonal pattern, in which growth in summer–fall was faster than that in winter–spring.
Population Structure and Genetic Divergence of Coastal Rainbow and Redband Trout in the Upper Klamath Basin
Abstract Freshwater-resident coastal rainbow trout Oncorhynchus mykiss irideus and the anadromous form of the subspecies, coastal steelhead (summer and winter runs), are present throughout the lower
A comparison of variability and population structure for major histocompatibility complex and microsatellite loci in California coastal steelhead (Oncorhynchus mykiss Walbaum)
The results indicate that, at the scale studied here, drift and migration play a major role in the observed geographical variability of MHC genes in steelhead, and that contemporary selection is relatively weak and difficult to detect.
Discovery and characterization of a large number of diagnostic markers to discriminate Oncorhynchus mykiss and O. clarkii
The availability of a large number of genetic markers for distinguishing genomic regions originating in these sister species will allow the detection of both recent and more distant hybridization events, facilitate the study of the evolutionary dynamics of hybridization and provide a powerful set of tools for the conservation and management of both species.


This paper shows how suitable evolutionary models can be constructed and applied objectively and how the type of data will affect both the method of treatment and the validity of the results.
Detection of reduction in population size using data from microsatellite loci
It is demonstrated that the mean ratio of the number of alleles to the range in allele size, which is calculated from a population sample of microsatellite loci, can be used to detect reductions in population size and that the value of M consistently predicts the reported demographic history for these populations.
