This book was released on 2004 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: The greenback cutthroat trout (Oncorhynchus clarki stomias) is classified as a threatened subspecies under the U.S. Endangered Species Act. Non-native brook trout (Salvelinus fontinalis) displace greenback cutthroat trout in montane streams, but the mechanisms for displacement are not understood. In this study, data on population dynamics, body condition, and feeding ecology of greenback cutthroat and brook trout were used in investigating competition for food and predation as potential mechanisms for displacement of greenback cutthroat trout by brook trout. During 2000 and 2001, trout populations and physical habitat were surveyed at 10 stream reaches in the South Platte and Arkansas River drainages in Colorado. Study areas included sites with (1) cutthroat trout only, (2) brook trout only, (3) both species, and (4) both species with experimental removal of brook trout. Complementary techniques, including analysis of stomach contents, stomach fullness, body condition, and stable isotopes of C and N, were used to describe the trophic niche of each species across the 10 sites.

Available in PDF, EPUB and Kindle. Book excerpt: This document focuses on the current status, distribution and range for five subspecies of cutthroat trout Oncorhynchus clarki, which are found largely on national forest system lands and ecosystems in the Rocky Mountain and Intermountain West within the U.S. from the Canadian to the Mexican border. The 5 subspecies -- Westslope, Yellowstone, Bonneville, Rio Grande, and Colorado River cutthroat trout -- are designated either species of special concern or sensitive. These subspecies are presently restricted to a fragment of their former range. Includes assessment methods, and origins and taxonomic theory. Illustrated.

This book was released on 2006 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Native salmonid populations in the inland West are often restricted to small isolated habitats at risk from invasion by nonnative salmonids. However, further isolating these populations using barriers to prevent invasions can increase their extinction risk. This monograph reviews the state of knowledge about this tradeoff between invasion and isolation. We present a conceptual framework to guide analysis, focusing on four main questions concerning conservation value, vulnerability to invasion, persistence given isolation, and priorities when conserving multiple populations. Two examples illustrate use of the framework, and a final section discusses opportunities for making strategic decisions when faced with the invasion-isolation tradeoff.
