Surveying an area dense with conflicting observations and ideas, this volume vividly depicts the current state of knowledge as well as the great diversity of opinion in the field of population ecology. Ten papers by outstanding authorities focus on three main issues-the effects of environment and population density on population dynamics, the influence of animal behavior on population growth, and the possibilities of genetic feedback or short-term evolutionary change on control of animal populations. An incisive introduction by the editor establishes a frame of reference and supplies succinct resolutions of some of the important controversies dealt with in these pages.

Animal Population Ecology focuses on the interaction between the various factors that affect an animal population. Population ecology is the study of the factors that determine the abundance of species and is concerned with the identification and mode of action of those environmental factors that cause fluctuations in population size and of those which determine the extent of these fluctuations. Organized into 11 chapters, the book initially examines some of the basic ideas about animal populations and defines many of the terms used by population ecologists. Then, it describes the action of the most important factors affecting population size. The interaction between these factors is demonstrated in chapters 8 and 9, wherein the results from studies of a few selected species are presented in detail. Finally, chapters 10 and 11 cover the development of generalized theories of population dynamics and their application to practical problems. With a strong focus on intensive study of animal populations in the field, rather than elaborate theories, the book will be helpful to population ecologists, animal researchers, teachers, and students.

Animal population densities are thought to be "regulated" by density-dependent processes (Haldane, 1953; Royama, 1977: Berryman, 1991). The perceived importance of these processes to biologists is evident from the vast amount of research dedicated to this idea (Inchausti, 1994). Most of this research addresses the problem(s) of detecting the effect of density-dependent regulatory processes using time series data. However, the question of the relative importance of density-dependent factors upon rates of change of population abundances is rarely addressed. In this thesis, I quantify the importance of density-dependent factors in 303 natural animal populations. I found that, on average, only $\approx$19% of the temporal variability in per capita growth rate could be statistically related to population density. Yet research effort concentrates overwhelmingly on density-dependent processes. I conclude that the effects of density-dependent processes within natural animal populations are generally weak and disproportionately studied.
