During the past 2 decades, the grizzly bear (Ursus arctos) population in the Greater Yellowstone Ecosystem (GYE) has increased in numbers and expanded in range. Understanding temporal, environmental, and spatial variables responsible for this change is useful in evaluating what likely influenced grizzly bear demographics in the GYE and where future management efforts might benefit conservation and management. We used recent data from radio-marked bears to estimate reproduction (1983-2002) and survival (1983-2001); these we combined into models to evaluate demographic vigor (lambda [k]). We explored the influence of an array of individual, temporal, and spatial covariates on demographic vigor. -- Abstract, first paragraph.

The world's first national park is constantly changing. How we understand and respond to recent events putting species under stress will determine the future of ecosystems millions of years in the making. Marshaling expertise from over 30 contributors, Yellowstone's Wildlife in Transition examines three primary challenges to the park's ecology.

Download Yellowstone Cougars Book in PDF, ePub and Kindle
Yellowstone Cougars examines the effect of wolf restoration on the cougar population in Yellowstone National Park—one of the largest national parks in the American West. No other study has ever specifically addressed the theoretical and practical aspects of competition between large carnivores in North America. The authors provide a thorough analysis of cougar ecology, how they interact with and are influenced by wolves—their main competitor—and how this knowledge informs management and conservation of both species across the West. Of practical importance, Yellowstone Cougars addresses the management and conservation of multiple carnivores in increasingly human-dominated landscapes. The authors move beyond a single-species approach to cougar management and conservation to one that considers multiple species, which was impossible to untangle before wolf reestablishment in the Yellowstone area provided biologists with this research opportunity. Yellowstone Cougars provides objective scientific data at the forefront of understanding cougars and large carnivore community structure and management issues in the Greater Yellowstone Ecosystem, as well as in other areas where wolves and cougars are reestablishing. Intended for an audience of scientists, wildlife managers, conservationists, and academics, the book also sets a theoretical precedent for writing about competition between carnivorous mammals.

Download In the Presence of Grizzlies Book in PDF, ePub and Kindle
Winner of ForeWord Magazine's 2006 Gold Award for Nature Book of the Year The most comprehensive and compelling chronicle of human–grizzly-bear interactions ever written, In the Presence of Grizzlies (formerly published as The Essential Grizzly) examines the fragile bond between ourselves and the quintessential alpha predator. Doug and Andrea Peacock contend that the conservation of big, wild, sometimes dangerous animals is essential for the survival of our own species and for the sense of humility necessary for rational thought. They explore a wide range of human-grizzly encounters through interviews with biologists, mauling victims, hunters, and photographers. To these they add unique portraits—sketches of real grizzlies from the bear’s viewpoint—and up-to-date commentary on such developments as the declassification of grizzlies as an endangered species. In the Presence of Grizzlies eclipses all existing books on bear behavior and bear attacks, providing readers with a twenty-first-century context for revisiting the original shudder of Homo sapiens—the bear in the cave of our genesis.

Download Energy Development and Wildlife Conservation in Western North America Book in PDF, ePub and Kindle
Energy Development and Wildlife Conservation in Western North America offers a road map for securing our energy future while safeguarding our heritage. Contributors show how science can help craft solutions to conflicts between wildlife and energy development by delineating core areas, identifying landscapes that support viable populations, and forecasting future development scenarios to aid in conservation design. The book frames the issue and introduces readers to major types of extraction quantifies the pace and extent of current and future energy development provides an ecological foundation for understanding cumulative impacts on wildlife species synthesizes information on the biological response of wildlife to development discusses energy infrastructure as a conduit for the spread of invasive species compares impacts of alternative energy to those of conventional development The final section calls for a shift away from site-level management that has failed to mitigate cumulative impacts on wildlife populations toward broad-scale planning and implementation of conservation in priority landscapes. The book concludes by identifying ways that decision makers can remove roadblocks to conservation, and provides a blueprint for implementing conservation plans. Energy Development and Wildlife Conservation in Western North America is a must-have volume for elected officials, industry representatives, natural resource managers, conservation groups, and the public seeking to promote energy independence while at the same time protecting wildlife.

Download Revisiting Brucellosis in the Greater Yellowstone Area Book in PDF, ePub and Kindle
Brucellosis is a nationally and internationally regulated disease of livestock with significant consequences for animal health, public health, and international trade. In cattle, the primary cause of brucellosis is Brucella abortus, a zoonotic bacterial pathogen that also affects wildlife, including bison and elk. As a result of the Brucellosis Eradication Program that began in 1934, most of the country is now free of bovine brucellosis. The Greater Yellowstone Area (GYA), where brucellosis is endemic in bison and elk, is the last known B. abortus reservoir in the United States. The GYA is home to more than 5,500 bison that are the genetic descendants of the original free-ranging bison herds that survived in the early 1900s, and home to more than 125,000 elk whose habitats are managed through interagency efforts, including the National Elk Refuge and 22 supplemental winter feedgrounds maintained in Wyoming. In 1998 the National Research Council (NRC) issued a report, Brucellosis in the Greater Yellowstone Area, that reviewed the scientific knowledge regarding B. abortus transmission among wildlifeâ€"particularly bison and elkâ€"and cattle in the GYA. Since the release of the 1998 report, brucellosis has re-emerged in domestic cattle and bison herds in that area. Given the scientific and technological advances in two decades since that first report, Revisiting Brucellosis in the Greater Yellowstone Area explores the factors associated with the increased transmission of brucellosis from wildlife to livestock, the recent apparent expansion of brucellosis in non-feedground elk, and the desire to have science inform the course of any future actions in addressing brucellosis in the GYA.
