Book Description
Microtine history indicates mosaic evolution and complex dispersal patterns around the Northern Hemisphere ; by reflecting this history and evaluating stage of population evolution, microtine biochronology can discriminate time periods as brief as 5,000 years.

Book Description
From the polar bear and the gray wolf to the walrus and river otter, there are 115 species of mammals in Alaska that have never been fully catalogued until now. Biologists Joseph A. Cook and Stephen O. MacDonald have compiled here the first comprehensive guide to all of Alaska’s mammals, big and small, endearing and ferocious. Through extensive fieldwork and research the authors have produced a unique and authoritative reference. Detailed entries for each species include distribution and taxonomic information, status, habitat, and fossil history. Appendices include quick reference listings of mammal distribution by region, specimen locations, conservation status, and the incidence of Pleistocene mammals. The guide is generously illustrated with line drawings by Alaskan artist W. D. Berry and includes several maps indicating populations and locations of species. Mammals of Alaska will be an accessible, easy to use source for scholars and hobbyists alike.

Book Description
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.
