Book Description
Eight species of hamster are found in Europe. The Common hamster (Cricetus cricetus) and the Golden hamster (Mesocricetus auratus) are popular pets but the others occur solely in eastern Europe living in agricultural or steppe-like habitats. The increase of agricultural production has led to an increase in their distribution. Some species are in decline but some species in some parts of Europe are regarded as pests. This study aims to give a summary of the status of hamsters in Europe. It summarises the biology, distribution and conservation status and analyses the causes of decline of the Common hamster and the state of the Romanian hamster. Ways of dealing with the conservation or management of the species are proposed

The Common Hamster (Cricetus Cricetus)
Author: Eva Millesi
Publisher:
ISBN:
Category : Nature
Languages : en
Pages : 132
Book Description
The Common Hamster is a fascinating species that differs from other hibernating small mammals in several aspects. Females have up to three litters per season and under favourable conditions both males and females are sexually mature in their first year. The ability to cache food changes the need for fattening prior to hibernation and consequently can alter the pattern of reproductive activity. The Common Hamster has lived in agricultural areas in close association with humans for centuries. During the last few decades, the loss of suitable habitats and modern agriculture technology have brought the species close to extinction in many areas. It has thus been listed as a highly threatened species in several European countries. Preventative measures require detailed knowledge about the biology of the species and a "hamster-friendly" management scheme in agricultural areas. In this volume, contributions made at the 13th Meeting of the International Hamster Workgroup have been summarized. Studies investigating burrow architecture, population dynamics, predation pressure, life span and reproductive activity underline the environmental flexibility of the species. The results of conservation programs are presented and discussed. Reports of breeding regimes with selected light-dark-cycles that can be used to optimize reproductive output and may benefit reintroduction projects have also been included. Generally the presented results should help broaden our knowledge about the Common Hamster and promote international networks to plan, implement, coordinate and evaluate management programs.

Asdell's Patterns of Mammalian Reproduction
Author: Virginia Douglass Hayssen
Publisher: Cornell University Press
ISBN: 9780801417535
Category : Nature
Languages : en
Pages : 1036
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.
