Asdell S Patterns Of Mammalian Reproduction

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.

A fascinating look at the diverse reproductive strategies of numerous female mammals, from hyenas to goats, kangaroos to whales. Newborn mammals can weigh as little as a dime or as much as a motorcycle. Some receive milk for only a few days, whereas others nurse for years. Humans typically have only one baby at a time following nine months of pregnancy, but other mammals have twenty or more young after only a few weeks in utero. What causes this incredible reproductive diversity? In Reproduction in Mammals, Virginia Hayssen and Teri J. Orr present readers with a fascinating examination of the varied reproductive strategies of a broad spectrum of mammals, from marsupials to whales. This unique book's comprehensive coverage gathers stories from many taxa into a single, cohesive perspective that centers on the reproductive lives of females. The authors shed light on a number of intriguing questions, including • do bigger moms have bigger babies? • do primates have longer pregnancies than other groups? • does habitat influence animals' reproductive patterns? • do carnivores typically produce larger litters than prey species? The book opens with the authors' definition of what constitutes a female perspective and an examination of the evolution of reproduction in mammals. It then outlines the typical individual mammalian female: her genetics, anatomy, and physiology. Taking a nuanced approach, Hayssen and Orr describe the female reproductive cycle and explore female mammals' interactions with males and offspring. Readers will come away from this thought-provoking book with an understanding of not only how reproduction fits into the lives of female mammals but also how biology has affected the enormously diverse reproductive patterns of the phenotypes we observe today.

To many, the contents of this conference may not seem appropriate at a time when the minds are preoccupied with a "population explosion." To the participants and guests of this conference, however, this was a week of fascinating discussions. While quantitative aspects of reproduc tion were touched upon, it was mostly a search for an understanding of the qualitative aspects of reproduction and its failure. Only when we understand these more completely will it be possible to render optimum care and have the foundations for meaningful population control. The conference was conceived in discussions at the Committee on Pathology of the National Academy of Sciences, W"ashington, in 1965. It was felt that investigators in medicine and the veterinary fields would profit greatly from a closer liaison. All too frequently, we work relatively isolated in our respective fields and, with the burgeoning information filling our journals, we have not enough time and leisure to stand back and attempt a comparative look at the subject of study. Often we are not familiar with the techniques other disciplines use, and which we could well employ to great advantage. ,,yhile this applies to many aspects of medicine, a comparative approach to the study of reproductive failure seemed most advantageous at this time.

The Deer and the Tiger is Schaller's detailed account of the ecology and behavior of Bengal tigers and four species of the hoofed mammals on which they prey, based on his observations in India's Kanha National Park. "This book is a treasure house of biological information and it is also a delight to read. . . . Excellent phoographs accompany the text."—Robert K. Enders, American Scientist "The one book that has been my greatest source of inspiration is The Deer and the Tiger by George Schaller, based on the first ever scientific field study of the tiger. . . . This book is written by a scientist, but speaks from the heart. . . . It reveals startling information on feeding habitats, territorial behaviour, and the nuances that make up the language of the forest; you become totally immersed in the world of the tiger. . . . For all of us who work in tiger conservation, this book is the bible."—Valmik Thapar, BBC Wildlife

Over 110 species of mammals roamed the forests, mountains, and deserts of this ancient "Land of Canaan"--Jordan, Israel, Syria, Lebanon, Palestine. Their impact on humans can be seen in cave drawings made by the Neanderthal inhabitants of northern Palestine some 200,000 years ago and gleaned from the writings of all Near Eastern civilizations. In recent centuries, encroachment by an increasing human population has resulted in the extinction of several species--aurochs (wild ox), red deer, onagers, Syrian wild asses roebucks (roe deer), fallow deer, Syrian brown bears, and cheetahs. Currently at risk are such large mammals as the leopard, wolf, wild cat, caracal, ibex, and dessert gazelles as well as may small mammals especially small carnivores, insectivores, and bats. Mammals of the Holy Land, summarizes the information that is known about the mammals that inhabit this historic land. with keys to identification, a glossary of terms, a basic introduction to the study of mammals, and a discussion of the impact these mammals have had on humans, a well as taxonomic and natural history information for each species, this book will be useful to both the professional and non-professional.

Acclaimed and coveted by both naturalists and lovers of wildlife illustration, Jonathan Kingdon's seven-volume East African Mammals has become a classic of modern natural history. This paperback edition makes Kingdon's remarkable artistic and scientific achievement—his hundreds of drawings and perceptive study of all the mammals in East Africa's species-rich fauna—available to the wide audience it deserves. Volume IIIA documents the carnivores of East Africa—lions, cheetahs, jackals, otters, civets, genets, mongooses, hyenas, and such lesser-known species as the zorilla and the aardwolf. The beauty of the animals, so vivid in these incomparable drawings, is made more poignant by the acknowledgment of their increasingly endangered status. Kingdon discusses the inevitable problems posed by large mammal communities in a developing continent and includes numerous maps indicating their declining ranges and populations.
