Conserving Genetic Diversity in Rainbow Trout (in Proc. Conference Biology & Management of Species and Habitats at Risk) Parkinson, Eric
1999

Abstract: Conserving genetic diversity is a major concern for north temperate fauna which are species poor but rich in 0genetic diversity. The problem is believed to be especially serious for freshwater fish where populations are isolated by barriers to migration. Isolation and low species diversity have been hypothesized to be the key ingredients in an adaptive radiation that has taken place in British Columbia fish since the last glaciation. Our work documents this variation and produces a within-species taxonomy of rainbow trout as a template for other species. Our work also incorporates both molecular data (presumably selectively neutral) as well as morphological and life history data (presumably adaptive). Molecular data are being used to identify ancient subdivisions within the species and patterns of gene flow among interconnected populations. Morphological and life history data will be used to group isolated populations into common adaptive ecotypes...
