Description: The book is a reflection on patterns of thought, theoretical positions, and research methods in population ecology. It advocates an approach which refrains from attempts at general mechanistic theory building, but which instead tries to explain population phenomena by life history characteristics, physiological and behavioural processes of organisms and to combine these facts in explanatory models. As far as possible the difference between individuals in morphology, physiology and behaviour should be taken into account, so that the connection of population ecology with the science of Neo-Darwinian evolution can be redressed again.

Description: This book examines the effects of environmental heterogeneity, or patchiness, on populations of plants and animals. The factors explored include variations in space, time, climactic conditions, food and other resources, and exposure to predators and parasites. In contrast to the once-prevailing view that environmental variation can be averaged-out without losing essential dynamics, the contributors to this volume find such heterogeneities often play a significant role in structuring large populations, especially in lessening the risk of extinction. Topics include the ways animals choose between patches that will expose them to different probabilities of starvation and predation, conservation in a variable environment and the optimal size of reserves, sex determination and sex ratios, patchiness and community structure, and extinctions of populations in correlated environments. The book will be of interest to ecologists, entomologists, environmental scientists, population geneticists, and biologists specializing in evolution, population, or conservation.

Description: In a work that will interest researchers in ecology, genetics, botany, entomology, and parasitology, Warren Abrahamson and Arthur Weis present the results of more than twenty-five years of studying plant-insect interactions. Their study centers on the ecology and evolution of interactions among a host plant, the parasitic insect that attacks it, and the suite of insects and birds that are the natural enemies of the parasite. Because this system provides a model that can be subjected to experimental manipulations, it has allowed the authors to address specific theories and concepts that have guided biological research for more than two decades and to engage general problems in evolutionary biology. The specific subjects of research are the host plant goldenrod (Solidago), the parasitic insect Eurosta solidaginis (Diptera: Tephritidae) that induces a gall on the plant stem, and a number of natural enemies of the gallfly. By presenting their detailed empirical studies of the Solidago-Eurosta natural enemy system, the authors demonstrate the complexities of specialized enemy-victim interactions and, thereby, the complex interactive relationships among species more broadly. By utilizing a diverse array of field, laboratory, behavioral, genetic, chemical, and statistical techniques, Abrahamson and Weis present the most thorough study to date of a single system of interacting species. Their interest in the evolutionary ecology of plant-insect interactions leads them to insights on the evolution of species interactions in general. This major work will interest anyone involved in studying the ways in which interdependent species interact.

Description: Population biology has been investigated quantitatively for many decades, resulting in a rich body of scientific literature. Ecologists often avoid this literature, put off by its apparently formidable mathematics. This textbook provides an introduction to the biology and ecology of populations by emphasizing the roles of simple mathematical models in explaining the growth and behavior of populations. This new edition has three significant extras compared to the successful first edition: first, it includes more problems and many of these now include answers. Second, it includes a series of spreadsheets written in Microsoft Excel to illustrate most of the models in the book. Third, the number of biological examples has been increased. The author assumes acquaintance with only elementary calculus, and provides tutorial explanations where needed to enhance the book's value to students in classes ranging from population biology and population ecology to mathematical biology and mathematical ecology.

Description: ~~A common tendency in the field of population ecology has been to overlook individual differences by treating populations as homogeneous units; conversely, in behavioral ecology the tendency has been to concentrate on how individual behavior is shaped by evolutionary forces, but not on how this behavior affects population dynamics. Adam Lomnicki and others aim to remedy this one-sidedness by showing that the overall dynamical behavior of populations must ultimately be understood in terms of the behavior of individuals. Professor Lomnicki's wide-ranging presentation of this approach includes simple mathematical models aimed at describing both the origin and consequences of individual variation among plants and animals. The author contends that further progress in population ecology will require taking into account individual differences other than sex, age, and taxonomic affiliation--unequal access to resources, for instance. Population ecologists who adopt this viewpoint may discover new answers to classical questions of population ecology. Partly because it uses a variety of examples from many taxonomic groups, this work will appeal not only to population ecologists but to ecologists in general.

Description: This book is a cohesive guide to the available methods that can be used in population viability analysis. It is therefore extremely valuable to both the practitioner of conservation biology and the theoretical population biologist.
