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.

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.

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 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.
