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.

Available in PDF, EPUB and Kindle. Book excerpt: The ten currently recognized species of grouse in North America have played an important role in America's history, from the famous but ill-fated heath hen, a primary source of meat for the earliest New England immigrants, to the ruffed grouse, currently one of the most abundant and soughtafter upland game birds in more than 40 states and provinces. This book summarizes the ecology, reproductive biology, and social behavior of all ten of the extant North American grouse species. It also describes the current status of grouse populations, some of which are perilously close to extinction. The social behavior of grouse is of special biological interest because among these ten species there is a complete mating system spectrum, from seasonally monogamous pair-bonding to highly promiscuous mating patterns. The latter group illustrates the strong structural and behavioral effects of sexual selection resulting from nonmonogamous mating. These influences reach a peak in the development by some grouse species of engaging in mating "leks," arena-like competitions performed by males while attempting to attract fertile females, and also provide opportunities for females to select optimum mating partners. These sexual competitions also promote strong differences evolving in sexual signaling behaviors ("displays") among closely related species. Nevertheless, a relatively high incidence of mating errors and resulting hybridization often occurs in spite of these marked behavioral differences. In addition to a text of 101,000 words, the book includes 16 range maps, 37 line drawings, and 38 photographs by the author, as well as nearly 1,400 literature citations.

Available in PDF, EPUB and Kindle. Book excerpt: We have written this book as a guide to the design and analysis of field studies of resource selection, concentrating primarily on statistical aspects of the comparison of the use and availability of resources of different types. Our intended audience is field ecologists in general and, in particular, wildlife and fisheries biologists who are attempting to measure the extent to which real animal populations are selective in their choice of food and habitat. As such, we have made no attempt to address those aspects of theoretical ecology that are concerned with how animals might choose their resources if they acted in an optimal manner. The book is based on the concept of a resource selection function (RSF), where this is a function of characteristics measured on resourceunits such that its value for a unit is proportional to the probability of that unit being used. We argue that this concept leads to a unified theory for the analysis and interpretation of data on resource selection and can replace many ad hoc statistical methods that have been used in the past.

Download or read book Grouse written by Ilse Storch and published by World Conservation Union. This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grouse have long attracted and fascinated people. Their display behavior, and their traditional communal mating grounds or "leks", have inspired poetry and folklore as well as scientific theories on sexual selection and mating systems. In many parts of their range, hunting plays a major role in the culture, economy, and subsistence of local communities. Although from a global perspective their status is not critical, grouse are far from being safe, and on a local scale, many local populations of grouse are declining and threatened with extinction. This plan provides a guide to the distribution, status, and threats to all grouse species; its major objective is to identify conservation priorities from a global perspective.

Book excerpt: That is what this book is about. It is a framework for planning, in which habitat is the key to managing wildlife and making forest managers accountable for their actions. This book is based on the collective knowledge of one group of resource professionals and their understanding about how wildlife relate to forest habitats. And it provides a longoverdue system for considering the impacts of changes in forest structure on all resident wildlife.
