This book was released on 1993 with total page 1036 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the appearance of the second edition of Sydney A. Asdell's widely used Patterns of Mammalian Reproduction in 1964, the field of reproductive physiology has expanded dramatically. Accordingly, this revision adopts a different structure from previous editions, substituting empirical delineations for physiological interpretations. With the emphases now on a presentation of the published facts of mammalian reproduction, it provides a thorough compilation of what is known about the basic reproductive biology of each of the 4300 mammalian species.To gather information, the authors examined more than 20,000 publications, dating up to 1992. They used primary sources as much as possible, supplementing them with English translations of Russian, Finnish, Chinese, and Japanese journals. The data are presented in taxonomic order. Each familial account summarizes the pattern of reproduction for the family and provides lists of citations arranged by topic of the literature on the endocrinology, reproductive anatomy, and reproductive physiology of the family. Following each account is a tabular listing of species-specific data for neonatal mass and size, weaning mass and size, litter size, age at sexual maturity, estrous cycle length, gestation length, lactation length, number of litters per year, and seasonality of reproduction. For each of these reproductive variables, the range of data gleaned from the literature is given, together with the source of each value listed.Virginia Hayssen is Assistant Professor of Biology at Smith College. Ari Van Tienhoven is Professor of Animal Physiology, Emeritus, at Cornell University. Ans Van Tienhoven assisted in the compilation of data for the book.

Available in PDF, EPUB and Kindle. Book excerpt: The George River caribou herd increased from 15,000 animals in 1958 to 700,000 in 1988 - the largest herd in the world at the time. The authors trace the fluctuations in this caribou population back to the 1700s, detail how the herd escaped extinction in the 1950s, and consider current environmental threats to its survival. In an examination of the life history and population biology of the herd, The Return of Caribou to Ungava offers a synthesis of the basic biological traits of the caribou, a new hypothesis about why they migrate, and a comparison to herd populations in North America, Scandinavia, and Russia. The authors conclude that the old maxim, "Nobody knows the way of the caribou," is no longer valid. Based on a study in which the caribou were tracked by satellite across Ungava, they find that caribou are able to navigate, even in unfamiliar habitats, and to return to their calving ground, movement that is central to the caribou's cyclical migration. The Return of Caribou to Ungava also examines whether the herd can adapt to global warming and other changing environmental realities.

This book was released on 2012-12-06 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: This third volume of articles dealing with advances in animal welfare science and philosophy covers a wide variety of topics. Major areas of discussion include the ethics and use of animals in biomedical research, farm animal behavior and welfare, and wildlife conservation. Three articles dealing with aspects of equine behavior and welfare cover new ground for this companion species. An in-depth study of the destruction of Latin America's tropical rain forests links the need for conservation and wildlife protection with the devastating impact of the international beef (hamburger) industry, and also highlights serious welfare problems in the husbandry of cattle in the tropics. Papers from a recent symposium at Moorhead State University, Animals and Humans: Ethical Perspectives have been included in this volume. Many of these are "benchmark" papers presenting the most up-to-date and documented evidence in support of animal welfare and rights. Articles oppos ing these position papers are included since they were part of the symposium, and because they provide the reader with a deeper understanding of the arguments given in support of various forms of animal exploitation. While there is no intent to endorse these views by publishing them, it should be acknowledged that without an open and scholarly exchange of opposing of constructive exchange and conflict resolution will views, the possibility remain remote.
