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.

What makes a mammal a mammal? How is a lion different from a dolphin? What is a primate? Classifying Living Things investigates how and why we group animals. Each book focuses on a particular class of living things, looking at the key characteristics that set its members apart from those of other classes. Discover how classes of living things have evolved, and how species have adapted to suit their environments. Find out why certain animals may show some characteristics of a particular class, but actually belong to another. 'Classifying Mammals' looks at the amazing class of furry, milk-drinking animals. Find out how mammals are grouped into orders and how each one is different from the rest. From aardvarks to zebras, from giant elephants to tiny shrews, discover what makes mammals so special.
