Abstract.— Cutthroat Trout Oncorhynchus clarkii of the Yellowstone River, Snake River, and Bonneville Basin exhibit tremendous diversity in the habitats and landscapes in which they are found, diversity in the life-history strategies they employ, and diversity in the coloration and spotting patterns they display. This chapter reviews substantial research conducted over the past 35 years that has described this diversity and the historical and more recent anthropogenic processes that have shaped it and highlights key findings that should be considered during taxonomic reassessments and the writing of conservation management plans.
