Admired for its elaborate breeding displays and treasured as a game bird, the Greater Sage-Grouse is a charismatic symbol of the broad open spaces in western North America. Unfortunately these birds have declined across much of their range—which stretches across 11 western states and reaches into Canada—mostly due to loss of critical sagebrush habitat. Today the Greater Sage-Grouse is at the center of a complex conservation challenge. This multifaceted volume, an important foundation for developing conservation strategies and actions, provides a comprehensive synthesis of scientific information on the biology and ecology of the Greater Sage-Grouse. Bringing together the experience of thirty-eight researchers, it describes the bird’s population trends, its sagebrush habitat, and potential limitations to conservation, including the effects of rangeland fire, climate change, invasive plants, disease, and land uses such as energy development, grazing, and agriculture.
Richly illustrated with photographs by award-winning nature photographer Noppadol Paothong, and accompanied by the text of accomplished natural history writer Kathy Love, this book tells the story of the sage-grouse, its habitat in the vast Sagebrush Sea of the Intermountain West, and the threats faced by both. Although the sage-grouse once flourished in many Western US states and provinces of Canada, in the past century its populations have diminished drastically. Today, fewer than 400,000 sage-grouse remain, and conservative legislation challenging the preservation of public wild lands increasingly threatens the sage- grouse. This book is designed not only to build awareness on the issues threatening the sage-grouse, but to stimulate and inspire readers to join the fight for environmental conservation and wilderness preservation. Bird lovers, nature enthusiasts, and residents of the American West will delight in viewing the beauty of the sage-grouse and emerge with a deeper sense of the many interests affecting the sagebrush ecosystem and the conservation efforts being implemented. This book is one of the most visually stunning and comprehensive documentations of one of the most iconic species of the United States, great for Bird lovers, nature enthusiasts, students, and residents of the American West.
"Summarizing current knowledge of grouse biology, this volume is organized in four sections--spatial ecology, habitat relationships, population biology, and conservation and management--and offers insights into spatial requirements, movements, and demography of grouse. Much of the research employs emerging tools in ecology that span biogeochemistry, molecular genetics, endocrinology, radio-telemetry, and remote sensing".--Adapted from publisher descrip tion on back cover
Integrated Population Models: Theory and Ecological Applications with R and JAGS is the first book on integrated population models, which constitute a powerful framework for combining multiple data sets from the population and the individual levels to estimate demographic parameters, and population size and trends. These models identify drivers of population dynamics and forecast the composition and trajectory of a population. Written by two population ecologists with expertise on integrated population modeling, this book provides a comprehensive synthesis of the relevant theory of integrated population models with an extensive overview of practical applications, using Bayesian methods by means of case studies. The book contains fully-documented, complete code for fitting all models in the free software, R and JAGS. It also includes all required code for pre- and post-model-fitting analysis. Integrated Population Models is an invaluable reference for researchers and practitioners involved in population analysis, and for graduate-level students in ecology, conservation biology, wildlife management, and related fields. The text is ideal for self-study and advanced graduate-level courses. - Offers practical and accessible ecological applications of IPMs (integrated population models) - Provides full documentation of analyzed code in the Bayesian framework - Written and structured for an easy approach to the subject, especially for non-statisticians

"Adaptive Strategies and Population Ecology of Northern Grouse" was first published in 1988. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. This book is at once a major reference to the species of grouse that inhabit North America and the Holarctic and a synthesis of all the available data on their ecology, sociobiology, population dynamics, and management. The book undertakes to answer two long-standing questions in population ecology: what actually regulates the numbers within a population, and what are the breeding and survival strategies evolved in this northern environment? For Volume I, editors Arthur T. Bergerud and Michael W. Gratson have drawn together their own work and that of colleagues in North America, Iceland, and Norway--in all, eleven research studies, averaging six years' duration, on eight species of grouse. These studies deal with the blue and ruffed grouse of the forest habitat; the sharp-tailed grouse, prairie chicken, and sage grouse of the prairie or steppe; and the white-tailed, rick, and willow ptarmigan found in alpine and arctic tundras. The authors describe the rich repertoire of behavior patterns developed by the hen and the cock to achieve their two primary objectives--first, to stay alive, and then to breed. Volume II, primarily the work of Bergerud, synthesizes the evidence in Volume I and in the grouse research literature from a theoretical perspective. Several potentially controversial sociobiological hypotheses are advanced to account for flocking behavior, migration, dispersal, roosting and feeding behavior, mate choice and mating systems. The demographic analysis provides new insights into cycles of abundance, the limitation of numbers, and the demographic factors that determine densities. The contributors, besides Bergerud and Gratson: R.C. Davies, A. Gardarson, J.E. Hartzler, R.A. Huempfner, D.A. Jenni, D.H. Mossop, S. Myrberget, R.E. Page, R.K. Schmidt, W.D. Svedarsky, and J.R. Tester.
"This Technical Note is primarily a review of literature on the fundamental habitat requirements of sage grouse and habitat management methods that may be used to perpetuate the species. It does not reiterate the life history, past distribution, species characteristics, and population dynamics"--Page 1.
Population genomics is revolutionizing wildlife biology, conservation, and management by providing key and novel insights into genetic, population and landscape-level processes in wildlife, with unprecedented power and accuracy. This pioneering book presents the advances and potential of population genomics in wildlife, outlining key population genomics concepts and questions in wildlife biology, population genomics approaches that are specifically applicable to wildlife, and application of population genomics in wildlife population and evolutionary biology, ecology, adaptation and conservation and management. It is important for students, researchers, and wildlife professionals to understand the growing set of population genomics tools that can address issues from delineation of wildlife populations to assessing their capacity to adapt to environmental change. This book brings together leading experts in wildlife population genomics to discuss the key areas of the field, as well as challenges, opportunities and future prospects of wildlife population genomics.
- Reveals an little-known yet iconic Western region that supports virtually all western wildlife species - A conservation priority area for Audubon, World Wildlife Fund, and the National Wildlife Federation, among others Located on the eastern side of the Rocky Mountains and stretching from Greater Yellowstone to Telluride, Colorado, the region known as the Sagebrush Sea is a unique wildlife habitat with an abundance of natural resources. For this reason it is treasured by conservationists, private land owners, and energy developers alike. The loss of this habitat would be catastrophic for important species like the Greater and Gunnison's Sage-grouse. Greater Sage-grouse were once found across thirteen western states, but due to energy development and conversion of land for agriculture, they now inhabit only half of their historic range. In addition, the gradual disappearance of sagebrush habitat in the West is having a profound effect on other wildlife species such as Brewer's sparrow, sage sparrow, sage thrasher, pygmy rabbit, mule deer, pronghorn, and more. Sage Spirit features each of these species and the threats they face. Photographer and writer Dave Showalter has documented the seasonal changes, animal behaviors, and migrations within the Sagebrush Sea. He is working with conservation leaders, government agencies, Native communities, and private landowners to tell the complete story of the ecosystem and the way humans are using the landscape. Through images and essays, Sage Spirit explains why responsible management of this fragile habitat is so vital.
