▼a Rainbow trout (Oncorhynchus mykiss) is a salmonid species, native to Pacific Ocean drainages in North America and eastern Russia, which exhibits fluvial (stream-resident), adfluvial (lake-migrant), and anadromous (ocean-migrant) ecotypes. The differentiation of fluvial and anadromous individuals in sympatry is well-studied, whereas comparatively little research has focused on the adfluvial form and its distinction from fluvial individuals in sympatry. Thus, the purpose of this dissertation was to investigate the ecological, genetic, and phenotypic diversity of nonanadromous rainbow trout in a natural stream-lake system to better understand the differentiation of fluvial and adfluvial individuals in sympatry, the basis of residency versus migration in this species, and the role of lakes in salmonid diversification. Rainbow trout were sampled in the lake (thus, by definition, adfluvial) and in several tributary streams (where adfluvial and fluvial individuals may co-occur), and were examined for a variety of features to develop a holistic understanding of the behavior, ecology, and evolution of these life history pathways.Stomach contents and stable isotopes revealed disparate trophic ecology among rainbow trout in connected stream and lake habitats, suggesting both an ontogenetic shift in the diet of adfluvial fish as well as divergence in diet between adfluvial and fluvial ecotypes. Rainbow trout in streams fed primarily on aquatic insects, while those in the lake largely consumed snails and amphipods |
