Role of Demographic, Genetic, and Environmental Factors Influencing the Spread of Hybridization Between Native Westslope Cutthroat and Non-Native Rainbow Trout

This research project examines dispersal and several components of fitness between hybrids and non-hybridized fish. Further, scientists will examine the relationship between environmental factors and genetic and demographic characteristics of hybrid populations. The specific objectives are: (1) to compare the spawning dynamics and dispersal More...

Genetics of Alaskan Fishes

Genetics of Alaska Fishes Projects studies include comparing molecular genetics for rainbow trout throughout their range in Alaska and use microsatellite analyses to look at hatchery and wild populations of steelhead in the Snake River (Phylogeographic analysis of rainbow trout in Alaska). Research also looks at genetic population structure of More...
