Animals of this size face different physiological and ecological challenges than larger mammals.
4.1.1 Demographic significance Confined populations grow more rapidly than populations from which dispersal is permitted (Lidicker, 1975; Krebs, 1979; Tamarin et at., 1984), and demography in island populations where dispersal is restricted differs greatly from nearby mainland populations (Lidicker, 1973; Tamarin, 1977, 1978; Gliwicz, 1980), clearly demonstrating the demographic signi ficance of dispersal. The prevalence of dispersal in rapidly expanding populations is held to be the best evidence for presaturation dispersal. Because dispersal reduces the growth rate of source populations, it is generally believed that emigration is not balanced by immigration, and that mortality of emigrants occurs as a result of movement into a 'sink' of unfavourable habitat. If such dispersal is age- or sex-biased, the demo graphy of the population is markedly affected, as a consequence of differ ences in mortality in the dispersive sex or age class. Habitat heterogeneity consequently underlies this interpretation of dispersal and its demographic consequences, although the spatial variability of environments is rarely assessed in dispersal studies.
Environmental conditions change considerably in the course of 24 h with respect to abiotic factors and intra- and interspecific interactions. These changes result in limited time windows of opportunity for animal activities and, hence, the question of when to do what is subject to fitness maximisation. This volume gives a current overview of theoretical considerations and empirical findings of activity patterns in small mammals, a group in which the energetic and ecological constraints are particularly severe and the diversity of activity patterns is particularly high. Following a comparative ecological approach, for the first time activity timing is consequently treated in terms of behavioural and evolutionary ecology, providing the conceptual framework for chronoecology as a new subdiscipline within behavioural ecology. An extensive Appendix gives an introduction to methods of activity modelling and to tools for statistical pattern analysis.
A summary of much of the experimental work on the spatial ecology of small mammals. This field has entered an exciting stage with such new techniques as GIS and systems modeling becoming available. Leading contributors describe and analyze the most well-known case studies and provide new insights into how landscape patterns and processes have had an impact on small mammals and how small mammals have, in turn, affected landscape structure and composition.
A comprehensive and invaluable resource, Methods for Ecological Research on Terrestrial Small Mammals is a must-have for any ecologist working on small mammals.

A wild, inventive ride of a short story collection from a distinctive new American storyteller. The author of the forthcoming novel, The Afterlives. The stories in Thomas Pierce’s Hall of Small Mammals take place at the confluence of the commonplace and the cosmic, the intimate and the infinite. A fossil-hunter, a comedian, a hot- air balloon pilot, parents and children, believers and nonbelievers, the people in these stories are struggling to understand the absurdity and the magnitude of what it means to exist in a family, to exist in the world. In “Shirley Temple Three,” a mother must shoulder her son’s burden—a cloned and resurrected wooly mammoth who wreaks havoc on her house, sanity, and faith. In “The Real Alan Gass,” a physicist in search of a mysterious particle called the “daisy” spends her days with her boyfriend, Walker, and her nights with the husband who only exists in the world of her dreams, Alan Gass. Like the daisy particle itself—“forever locked in a curious state of existence and nonexistence, sliding back and forth between the two”—the stories in Thomas Pierce’s Hall of Small Mammals are exquisite, mysterious, and inextricably connected. From this enchanting primordial soup, Pierce’s voice emerges—a distinct and charming testament of the New South, melding contemporary concerns with their prehistoric roots to create a hilarious, deeply moving symphony of stories.
Blackwell's Five-Minute Veterinary Consult: Small Mammal brings together a wide range of information on diseases commonly seen in small exotic mammals into a single, accessible resource. With consistency and broad coverage unparalleled by other texts, this new edition adds sections on chinchillas, guinea pigs, and rodents to the existing rabbit and ferret topics to offer complete coverage of these popular, yet less commonly treated, species. Detailed, up-to-date information on the diagnosis and treatment options for all disorders commonly encountered in exotic companion animals is readily accessible, making this a go-to reference for any veterinarian seeing small exotic mammals, regardless of their experience level with these species. Divided into sections by species, topics are organized alphabetically, with a standardized layout that makes it easy to find information. The Second Edition includes access to customizable Client Education Handouts, which can be downloaded and used in the veterinary clinic, on a companion website at www.wiley.com/go/oglesbee. This book is an essential purchase for general practitioners treating exotic companion animals, exotic animal veterinarians, and veterinary students.
From the tiny shrew to the black bear, Pennsylvania's hills and valleys are teeming with sixty-three species of wild mammals. Many of these animals are rarely seen except when pursued by an interested biologist, mammologist, or nature photographer. Now, with the publication of this book, student, scholar, and nature lover alike will have a ready reference to distinguish between a deer mouse and a white-footed mouse, to identify raccoon tracks, and to learn about Pennsylvania's other inhabitants. An attractive backpack-size volume, written in lively prose, the Guide to the Mammals of Pennsylvania opens with a short introduction to Pennsylvania's environment and the characteristics defining a mammal. The bulk of the book consists of species accounts of the mammals grouped into families and orders. Each account includes a short list of data, a Pennsylvania range map, a North American range map, and a narrative of the physical, ecological, and behavioral characteristics of the species. Exciting photographs of each of the species in its natural habitat, 17 in color, and drawings of animal tracks are especially useful for identification, and a glossary and a bibliography provide definitions and references for the serious reader. Naturalists, whether amateur or professional, will find the book useful in the field; it will be an indispensable tool in the classroom.
This book provides a comprehensive survey of the diversity and biology of metazoan parasites affecting small mammals, of their impact on host individuals and populations, and of the management implications of these parasites for conservation biology and human welfare. Designed for a broad, multidisciplinary audience, the book is an essential resource for researchers, students, and practitioners alike.
