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: Over the last century, native trout have experienced dramatic population declines, particularly in larger river systems where habitats associated with different spawning life history forms have been lost through habitat degradation and fragmentation. The resulting decrease in life history diversity has affected the capacity of populations to respond to environmental variability and disturbance. Unfortunately, because few large rivers are intact enough to permit full expression of life history diversity, it is unclear what patterns of diversity should be a conservation target. In this study, radiotelemetry was used to identify spawning and migration patterns of Snake River Finespotted Cutthroat Trout Oncorhynchus clarkii behnkei in the upper Snake River. Individuals were implanted with radio tags in October 2007 and 2008, and monitored through October 2009. Radio-tagged cutthroat trout in the upper Snake River exhibited variation in spawning habitat type and location, migration distance, spawn timing, postspawning behavior, and susceptibility to mortality sources. Between May and July, Cutthroat Trout spawned in runoff-dominated tributaries, groundwater-dominated spring creeks, and side channels of the Snake River. Individuals migrated up to 101 km from tagging locations in the upper Snake River to access spawning habitats, indicating that the upper Snake River provided seasonal habitat for spawners originating throughout the watershed. Postspawning behavior also varied; by August each year, 28% of spring-creek spawners remained in their spawning location, compared with 0% of side-channel spawners and 7% of tributary spawners. These spawning and migration patterns reflect the connectivity, habitat diversity, and dynamic template of the Snake River. Ultimately, promoting life history diversity through restoration of complex habitats may provide the most opportunities for cutthroat trout persistence in an environment likely to experience increased variability from climate change and disturbance from invasive species.

This book was released on 2013 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life-history diversity, movement patterns, and habitat associations of cutthroat trout Oncorhynchus clarkii have been widely studied in smaller river systems and are critical components of conservation planning. However, much less is known about how the patterns observed in smaller systems may "scale up" in larger, complex river systems. In my dissertation, I evaluated the life-history variation and spatial ecology of Snake River finespotted cutthroat trout O. c. behnkei in the upper Snake River, WY and collaborated on a statistical method to characterize habitat occupancy from radio-telemetry data. For my first chapter, I identified the life-history diversity and movement patterns of cutthroat trout in a large river network using radio-telemetry. Spawning occurred from May through July throughout the upper Snake River in spring creeks, tributaries, and side channels over a spatial extent> 100 km. Postspawning movement patterns varied among spawning areas and life-history forms. Results indicated that life-history diversity in large river networks is substantially more complex than may be observed in headwater systems, reflecting increased habitat complexity and availability in larger systems. For my second chapter, I collaborated on a method to address three biases in radio-telemetry datasets: (1) data may be collected at sparse, unequal sampling intervals, (2) encountering an individual in a location does not imply occupancy, and (3) all locations between where individuals are encountered are occupied to some extent, despite the lack of observations. The resulting adaptive kernel density interpolation method treated location as a utilization distribution for each tracking interval (e.g., a week) and estimated time spent per location as a function of individual movement speed and time since last relocation. For my third chapter, I evaluated habitat occupancy and movement patterns at multiple spatiotemporal scales. Spatial variation and hierarchical structure in the physical template interacted to produce contextual variation in the availability and function of habitat attributes (e.g., wood functioning as cover or as a velocity break). Collectively, these studies provide a more complete understanding of life-history diversity in a large river network and the way in which variation in the physical template shapes habitat occupancy, and movement patterns.

This book was released on 2014 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The upper South Fork Snake River in Idaho supports one of the last remaining large- river populations of Yellowstone cutthroat trout (Oncorhynchus clarkii bouveri), which is threatened by competition and hybridization with introduced rainbow trout (O. mykiss). The Idaho Department of Fish and Game has implemented a three-pronged approach to preserving Yellowstone cutthroat trout that consists of reproductive isolation using barrier weirs, flow management, and angler harvest of rainbow/hybrid trout. This thesis presents an updated and expanded version of a model of the population dynamics of Yellowstone cutthroat trout and rainbow/hybrid trout that is used to conduct simulation experiments to predict the likely outcomes of multiple potential management scenarios and identify the management combinations most likely to result in long-term persistence of Yellowstone cutthroat trout in the study reach. A discrete-time, age-structured population model tracks same age cohorts of tributary-spawning Yellowstone cutthroat trout, river-spawning Yellowstone cutthroat trout, and rainbow/hybrid trout separately through life stages, population interactions, and mortality, including spawning and hybridization, potential peak spring flow-induced mortality of eggs and fry, age-0 competition for flow-dependent habitat during the first winter, and size-dependent angler harvest of rainbow/hybrid trout.
