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.

Available in PDF, EPUB and Kindle. 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.

Book Colorado River Cutthroat Habitat Resistance and Resilience to Climate Change

Download or read book Colorado River Cutthroat Habitat Resistance and Resilience to Climate Change written by Kate Olsen and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Colorado River cutthroat trout, Oncorhyncus clarki pleuriticus, occupy less than 12% of their historic range. Restoration and conservation of this species are currently under way across the upper Colorado River basin, but guidance to inform management decisions related to the impacts of climate change on cutthroat is lacking. Shifts in the thermal distribution of freshwater fish have been documented, and will continue to occur as cold water habitat is threatened by warming water temperatures. Coupled air and water temperature data allow for an estimation of potential resistance and resilience to warming, determining the effect that local air has on stream temperature. The United States Forest Service, cooperating with federal agencies, state agencies and private landowners, placed temperature loggers in the water and two air locations at 50 sites. To select a representative subset of sites, six habitat characteristics of each Colorado River cutthroat trout core conservation population were considered. These characteristics include solar input, elevation, watershed area, riparian vegetation, groundwater input, and the 30-year mean maximum July air temperature. Results from coupled temperature loggers indicate that the relationship between air and water temperature in the upper Colorado River basin is neither linear, nor one-to-one. Using Mohseni's (2003) equation, the relationship between air and water temperature was fit to a nonlinear regression curve. Analysis shows that the median rise in daily maximum water temperature is only 0.41℗ʻC for a 1.0℗ʻC increase in the median daily maximum air temperature. Air temperature exerts the most influence over water temperature; however, these results indicate that there are other characteristics that influence stream temperature. To determine these characteristics, analysis of the six habitat characteristics used for site selection in addition to aspect, slope, and latitude were used to model multiple temperature metrics. The best model, nonlinear water to air temperature relationship, had an R2 between actual and predicted values of 0.71. It also became clear that using multi-metric analysis would provide a much more robust indicator of resistance. This work will allow managers to consider potential climate change resistance or resilience in project prioritization, by understanding potential habitat characteristics to buffer stream warming.

Book Movement and Habitat Use of Bonneville Cutthroat Trout Oncorhynchus Clarki Utah

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Movement patterns and habitat use of Bonneville cutthroat trout (Oncorhynchus clarki Utah) in tributaries of the Logan River watershed are greatly affected by habitat alterations created by North American Beaver (Castor canadensis). Evaluation of cutthroat trout habitat use in these watersheds is also complicated by biotic interactions with invasive brown trout (Salmo trutta) and brook trout (Salvelinus fontinalis). My objectives in this thesis were to 1.) Evaluate the passage of beaver dams by each trout species in the Temple Fork watershed and 2.) Evaluate the habitat use of cutthroat trout in the presence of brown trout and brook trout over a range of spatial scales. To address these objectives, 1381 trout were tagged with passive integrated transponder tags. Their locations were recorded using a combination of annual capture/recapture surveys, stationary in-stream antennas, and monthly continuous mobile antenna surveys. To address objective 1, sh were located above and below 22 beaver dams to establish whether sh passed dams and to identify downstream and upstream passage; 187 individual trout were observed making 481 passes of all 22 beaver dams. Native Bonneville cutthroat trout passed dams more frequently than both non-native brown trout and brook trout. It was determined that spawning timing affected seasonal changes in dam passage for each species. Physical characteristics of dams such as height and upstream location affected the passage of each species. Movement behaviors of each trout species were also evaluated to help ex- plain dam passage. These data suggest beaver dams are not acting as barriers to movement for cutthroat and brook trout but may be impeding the movements of invasive brown trout. To address objective 2, a hierarchical classification of stream habitat was created using the River Styles framework. The River Styles framework not only establishes a relationship between habitats at dierent scales, but also attempts to understand the processes that create and maintain those habitats. The location of each sh observation was associated with habitats at the stream, landscape unit, River Style, and geomorphic unit levels. Habitat use of each species of sh was evaluated at each spatial scale using all sh observations over the four-year study period. Hotspot locations, or locations used consistently by a species of sh consistently through time, were also evaluated across the entire study period and over each year. It was found that brook trout almost exclusively use the beaver ponds and beaver-altered habitats in Spawn Creek. Brown trout were not found in the upper- most parts of both Spawn Creek and Temple Fork. They were also found more than the other species in pools created by bedrock or man-made control features, suggesting that they select highly stable habitats. Cutthroat trout were found more than brown trout in beaver-altered habitats and lateral scour pools, suggesting that they select more dynamic, naturally occurring habitats.
