Book excerpt: Cutthroat tells the full story of the genuine native trout of the American West. This new edition, thoroughly revised and updated after 20 years, synthesizes what is currently known about one of our most interesting and colorful fishes, includes much new information on its biology and ecology, asks how it has fared in the last century, and looks toward its future. In a passionate and accessibly written narrative, Patrick Trotter, fly fisher, environmental advocate, and science consultant, details the evolution, natural history, and conservation of each of the cutthroat's races and incorporates more personal reflections on the ecology and environmental history of the West's river ecosystems. The bibliography now includes what may be the most comprehensive and complete set of references available anywhere on the cutthroat trout. Written for anglers, nature lovers, environmentalists, and students, and featuring vibrant original illustrations by Joseph Tomelleri, this is an essential reference for anyone who wants to learn more about this remarkable, beautiful, and fragile western native.

Book excerpt: Background For wide-ranging species, intraspecific variation can occur as a result of reproductive isolation from local adaptive differences or from physical barriers to movement. Cutthroat trout (Oncorhynchus clarkii), a widely distributed fish species from North America, has been divided into numerous putative subspecies largely based on its isolation in different watersheds. In this study, we examined mtDNA sequence variation of cutthroat trout to determine the major phylogenetic lineages of this polytypic species. We use these data as a means of testing whether geographic isolation by watershed boundaries can be a primary factor organizing intraspecific diversification. Results We collected cutthroat trout from locations spanning almost the entire geographic range of this species and included samples from all major subspecies of cutthroat trout. Based on our analyses, we reveal eight major lineages of cutthroat trout, six of which correspond to subspecific taxonomy commonly used to describe intraspecific variation in this species. The Bonneville cutthroat trout (O. c. utah) and Yellowstone cutthroat trout (O. c. bouvieri) did not form separate monophyletic lineages, but instead formed an intermixed clade. We also document the geographic distribution of a Great Basin lineage of cutthroat trout; a group typically defined as Bonneville cutthroat trout, but it appears more closely related to the Colorado River lineage of cutthroat trout. Conclusion Our study indicates that watershed boundaries can be an organizing factor isolating genetic diversity in fishes; however, historical connections between watersheds can also influence the template of isolation. Widely distributed species, like cutthroat trout, offer an opportunity to assess where historic watershed connections may have existed, and help explain the current distribution of biological diversity across a landscape.

Available in PDF, EPUB and Kindle. Book excerpt: One important goal of fisheries managers is the preservation of the breeding populations of native species. The cutthroat trout, Salmo clarki, is the trout species native to the Rocky Mountains and is found in several independent drainage systems on both sides of the Continental Divide. The cutthroat trout in Yellowstone and Grand Teton National Parks are among the last representatives of a gene pool which had become well adapted over thousands of years to the environmental conditions prevalent in this area. Non-native trout species, however, have been introduced into this aream in the past with which the native cutthroat trout might hybridize. For the past few years we have been employing both biochemical and cytogenetic techniques to evaluate the taxonomic status and assess the purity of cutthroat trout populations in Yellowstone and Grand Teton National Parks. The objectives of the cytogenetic portion of this research project were : to compare cytogenetically the cutthroat trout populations present in Yellowstone National Park ; to determine the extent of within individual and between individual variation in the chromosomal constitution of cutthroat trout ; to assess the purity of the existing cutthroat trout populations in Yellowstone National Park by looking for cytogentic evidence of introgression between cutthroat and non-native rainbow trout ; and to evaluate the taxonomic status of the Colorado River cutthroat trout. The report describes the results of the cytogenetic portion of our studies. The results of the electrophoretic studies will be submitted separately by Dr. Loudenslager.
