Behavioral, ecological, and fitness consequences of hybridization between native westslope cutthroat trout (Oncorhynchus clarkii lewis) and nonnative rainbow trout (O. mykiss): Author: Muhlfeld, Clint Cain; Date: 2008-12-15; Program: Fish and Wildlife Biology; Abstract: Anthropogenic hybridization is one of the greatest threats to global biodiversity. Hybridization and introgression may lead to a loss of locally adapted gene complexes and ecological adaptations in native populations, yet these potential consequences have not been fully evaluated in nature. I investigated factors influencing the spread of hybridization between native westslope cutthroat trout (Oncorhynchus clarkii lewisi) and nonnative rainbow trout (O. mykiss) in the upper Flathead River system, Montana (USA) and British Columbia (Canada). The fundamental questions of my dissertation were: wh...; Download File | View full details
