Book Description
ON THE FUTURE OF PERSPECTIVES When Patrick Bateson and Peter Klopfer offered me the editorship of Perspectives in 1992, the world of academic publishing was in one of its periodic upheavals. Subscriptions to series-even distinguished series such as Perspec tives-had been declining and individual volume prices had been rising, a trend that if continued could only result in the series pricing itself out of the market. In the course of the negotiations around the change of editors, the publishers offered a cost-cutting solution: change the production pattern to "camera ready" and elimi nate the costs of indexing and proofreading. While I could see the sense in this proposal, I was reluctant to accept it. Part of what I had always liked about the volumes in this series was that they were real books, intelligently proofread, nicely laid out, and provided with proper indexes. Thus, I in return offered a "Devil's bargain": the publisher should maintain the present quality of the series for two more volumes and make a renewed effort to advertise the series to our ethological and sociobiological colleagues, while I as the new series editor committed myself to a renewed effort to make Perspectives the publication of choice for writers who are trying to get their message out to the world intact and readers who are seeking clear, coherent, comprehensive and untrammeled presentations of authors' ideas and research programs.

Book Description
The first comprehensive treatment of North American rodents of conservation concern. This action plan summarizes the rodent fauna of North America and provides available information on every rodent taxon that has been considered to be of conservation concern by state, provincial and private conservation agencies and regional experts. It is hoped that the survey provided in this action plan will serve as a common ground for all these parties in drawing up conservation strategies for rodents.

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
Animal Vigilance builds on the author's previous publication with Academic Press (Social Predation: How Group Living Benefits Predators and Prey) by developing several other themes including the development and mechanisms underlying vigilance, as well as developing more fully the evolution and function of vigilance. Animal vigilance has been at the forefront of research on animal behavior for many years, but no comprehensive review of this topic has existed. Students of animal behavior have focused on many aspects of animal vigilance, from models of its adaptive value to empirical research in the laboratory and in the field. The vast literature on vigilance is widely dispersed with often little contact between models and empirical work and between researchers focusing on different taxa such as birds and mammals. Animal Vigilance fills this gap in the available material. - Tackles vigilance from all angles, theoretical and empirical, while including the broadest range of species to underscore unifying themes - Discusses several newer developments in the area, such as vigilance copying and effect of food density - Highlights recent challenges to assumptions of traditional models of vigilance, such as the assumption that vigilance is independent among group members, which is reviewed during discussion of synchronization and coordination of vigilance in a group - Written by a top expert in animal vigilance
