Book Description
Wild Mammals of Wyoming and Yellowstone National Park provides the scholar, conservationist, and interested lay reader with information on the state's 117 wild mammalian species from grizzly bears to pygmy shrews. It describes the history of mammalogy in Wyoming, the zoogeography of Wyoming mammals, and the prehistoric mammals of Wyoming. It also characterizes the habitats of Wyoming mammals and addresses the conservation and management of mammals in the region. Expanding beyond the traditional field guide, Steven W. Buskirk emphasizes taxonomic classification, geographic range, and conservation status for mammalian species. Introductory sections are provided for each order and family, and individual species accounts organize a wealth of data ranging from habitat associations to field measurements in an easy-to-use format. Featuring color species photos, continental and state-scale distribution maps, and a comprehensive bibliography with nearly 1,000 references, Wild Mammals of Wyoming and Yellowstone National Park is an indispensable resource for wildlife and conservation biologists and mammalogists working in this region.

Book Description
"The introduction of exotic lake trout (Salvelinus namaycush) to Yellowstone Lake in Yellowstone National Park has contributed to a significant decline in the heretofore healthy population of Yellowstone cutthroat trout (Oncorhynchus clarki bouvieri). There is great concern not only regarding the persistence of this genetically pure cutthroat subspecies, but also for the potential impacts their disappearance will have on the fish-eating predators of Yellowstone Lake and the surrounding community. Nearby Lewis Lake has no cutthroat trout, but is home to a well-established population of non-native lake trout, brown trout (Salmo trutta), and Utah chub (Gila atraria). We examined the contents of 179 river otter (Lontra canadensis) scats collected along the shores of Yellowstone (n=101) and Lewis Lakes (n=78) in Yellowstone National Park to compare otter dietary habits, especially with regard to the mustelid's utilization of native vs. non-native fish species. We also assessed diets using stable isotopes analysis ... on otters and represenatative prey from both lakes. In addition, we analyzed the isotopic signatures of fur taken from Yellowstone Lake otter specimens collected in the early part of the 20th century before exotic trout were introduced. Fecal analysis indicated that trout were consumed much more frequently by contemporary Yellowstone Lake otters (57% annually) than by otters occupying Lewis Lake (12% annually). The predominant fish found in Lewis Lake otter feces were minnows, presumably Utah chub. Stable isotopes analysis, however, identified longnose suckers (Catostomus catostomus) as the primary fish prey for Yellowstone Lake otters (56% contribution to otter diet), while indicating that otters there are generally preying on neither cutthroat trout nor introduced lake trout. Analysis of stable isotopes also indicated that contemporary Yellowstone Lake otters forage at a lower trophic level ... than their historic counterparts ... Isotopic data from Lewis Lake revealed that brown trout (60% contribution to otter diet) contribute more to otter diets there than local lake trout and Utah chub together (40% combined contribution). This study establishes the importance of alternative prey species to otters foraging on both lakes and supplements the growing body of research demonstrating that lake trout will not constitute a major food source for Yellowstone river otters."--Abstract.

Book Description
Visitors to Yellowstone National Park are drawn to the spectacular scenery, unique thermal features, and the large numbers of wild animals easily observed in their natural habitat. The thoughtful visitor to the park cannot help but be captivated by the unparalleled breadth of scientific knowledge needed to understand the intricate interrelationships that make up the yellowstone landscape. Knowing Yellowstone explores how scientists discover what they know about America's first national park and the surrounding lands. The chapter authors are scientists who represent the best of their fields of study. The science they describe is leading the way to our understanding of complex ecosystems worldwide.

Book Description
The loss and fragmentation of natural habitats is one of the major issues in wildlife management and conservation. Habitat "corridors" are sometimes proposed as an important element within a conservation strategy. Examples are given of corridors both as pathways and as habitats in their own right. Includes detailed reviews of principles relevant to the design and management of corridors, their place in regional approaches to conservation planning, and recommendations for research and management.

Book Description
Scientists have been warning for years that human activity is heating up the planet and climate change is under way. We are only just beginning to acknowledge the serious effects this will have on all life on Earth. The federal government is crafting broad-scale strategies to protect wildland ecosystems from the worst effects of climate change. One of the greatest challenges is to get the latest science into the hands of resource managers entrusted with vulnerable wildland ecosystems. This book examines climate and land-use changes in montane environments, assesses the vulnerability of species and ecosystems to these changes, and provides resource managers with collaborative management approaches to mitigate expected impacts. Climate Change in Wildlands proposes a new kind of collaboration between scientists and managers--a science-derived framework and common-sense approaches for keeping parks and protected areas healthy on a rapidly changing planet.

Book Description
The world's climate is changing, and it will continue to change throughout the 21st century and beyond. Rising temperatures, new precipitation patterns, and other changes are already affecting many aspects of human society and the natural world. In this book, the National Research Council provides a broad overview of the ecological impacts of climate change, and a series of examples of impacts of different kinds. The book was written as a basis for a forthcoming illustrated booklet, designed to provide the public with accurate scientific information on this important subject.
