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

Book Description
There is more to biological rhythms than circadian clocks. This book aims at promoting the exciting potential of a deeper understanding of circannual, circatidal, and circalunar clocks. It highlights new developments, summarizes existing knowledge, and integrates different perspectives with the tools and ideas of diverse fields of current biology. For predominantly pragmatic reasons, research in recent decades was mostly concerned with circadian clocks. Clocks on other timescales, however, have been largely neglected and therefore still appear "enigmatic". Thanks to the rapid development of methods in molecular biology as well as in ecology, we are now able to re-approach these clocks. Laboratories around the world are showing fresh interest and substantial progress is being made in many independent projects. The book's two sections address the moon-derived circatidal, circasemilunar, and lunar cycles on the one hand (10 chapters), and the sun-derived circannual cycles on the other (6 chapters). This work brings together authors with an expansive array of expertise and study systems, ranging from tidal cycles of marine invertebrates to annual cycles of birds and mammals, and from behavioral to genetic and epigenetic backgrounds. While great challenges remain to be mastered, the book aims at conveying the excitement of unraveling, broadly, the rhythms of life.

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.

Book Description
This volume reviews the ecological effects of road, rail, marine and air transport. The focus ranges from identification of threats and repair of damaging effects to design of future transport systems that minimize environmental degradation. The scope of coverage extends from small ecosystems to the planet as a whole. Experts from a variety of disciplines address the topic, expressing views across the spectrum from deep pessimism to cautious optimism.
