Book Description
From their largely descriptive beginnings about a half century ago, studies on the ecology of small mammals have mushroomed in number, scope, content and complexity. Yet strangely, or perhaps not so strangely if one considers the extent and complexity of ecological interactions, the main problems for which the early workers sought answers still defy complete analysis, and basic hypotheses remain untested if not even untestable. The same holds true for so many branches of animal ecology that it seems to be the complexity of the concepts that frustrates efforts rather than the subject species. Like all branches of science, small mammal ecology has been subject to a series of fashionable approaches, one following another as tech nology penetrates previously impregnable regions. Doubtless the future development of our science will be punctuated by wave upon wave of new endeavour in whole fields that are perhaps even yet unidentified. Answers to the complex questions which ecologists ask do not come easily. Increasingly though, they arise in direct proportion to the efforts expended upon their elucidation. Many studies have achieved such a high level of elegance, in terms of manpower and apparatus, that there is a feeling that questions asked when such resources are unavailable are not worth asking. Nothing could be further from the truth. Many a complex model has failed fully to explain the phenomenon for which it was construc ted because of a lack of basic field data on the species' natural h~story.

Book Description
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.

Book Description
All the information researchers, students, and practitioners need to conducted innovative, state-of-the-art research on small mammals. Rodents and insectivores constitute the vast majority of mammals on our planet, yet we often overlook the importance of this group. As seed dispersers, prey species, and disease regulators, these animals are critical to the functioning of our ecological systems. While considerable material exists that describes these species, there has been no dedicated guide explaining how to effectively research them—until now. Methods for Ecological Research on Terrestrial Small Mammals is a one-stop resource compiling all the information readers need to conduct state-of-the-art research on small terrestrial mammals across the globe. The authors cover the full spectrum of issues, from capture, handling, identification, reproduction, demography, and taxonomy to behavior, diet, evolution, diseases, movements, morphometrics, and more. They also: • highlight the latest techniques while carefully explaining the tried-and-tested methods needed to conduct rigorous scientific inquiries; • provide step-by-step examples and case studies, demonstrating how the methods discussed can be used in actual research projects; • compare and contrast methodologies, analytical techniques, and software packages, helping researchers determine which pathways and tools will yield the best results for their studies. A comprehensive and invaluable resource, Methods for Ecological Research on Terrestrial Small Mammals is a must-have for any ecologist working on small mammals.

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
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.
