This book provides an introduction to population dynamics, exploring rules that govern change in any dynamic system and applying these general principles to populations of living organisms. Principles of Population Dynamics and their Application is aimed at applied ecologists, resource managers. and pest managers. It is also aimed at undergraduate students taking courses in forestry, fisheries, widlife and pest management.
For over sixty years, understanding the causes of multiannual cycles in animal populations has been a central issue in ecology. This book brings together ten of the leaders in this field to examine the major hypotheses and recent evidence in the field, and to establish that trophic interactions are an important factor in driving at least some of the major regular oscillations in animal populations that have long puzzled ecologists.
This unique book is concerned with the general principles and theories of population ecology, based on the idea that the rules governing the dynamics of populations are relatively simple, and that the rich behavior we observe in nature is a consequence of the structure of the system rather than of the complexity of the underlying rules. From this perspective, the dynamic behavior of single-species populations is examined and an elementary feedback model of the population system is developed. This single-species model is refined and generalized by examining the mechanisms of population regulation.
This book is intended as a general text for undergraduates studying the manage ment of forest insect pests. It is divided into four parts: insects, ecology, manage ment, and practice. Part I, Insects, contains two chapters. The first is intended to provide an overview of the general attributes of insects. Recognizing that it is impossible to adequately treat such a diverse and complex group of organisms in such a short space, I have attempted to highlight those insectan characteristics that make them difficult animals to combat. I have also tried to expose the insects' weak points, those attributes that make them vulnerable to manipulation by human actions. Even so, this first chapter will s...
Biological control is the suppression of pest populations using predators, parasitoids and pathogens. Historically, biological control has largely been on a trial-and-error basis, and has failed more often than it has succeeded. However by developing theories based upon fundamental population principles and the biological characteristics of the pest and agent, we can gain a much better understanding of when and how to use biological control. This book gathers together recent theoretical developments and provides a balanced guide to the important issues that need to be considered in applying ecological theory to biological control. It will be a source of productive and stimulating thought for all those interested in pest management, theoretical ecology and population biology.

One of the themes of the 20th International Congress of Entomology held in Florence in August 1996 was ecology and population dynamics, with papers presented on single species dynamics, population interactions, and community ecology. This text contains a selection of the papers that were presented, and gives and late-1990s picture of the developing area. It should be of interest to biometricians and general population ecolgists, as well as entomologists.
A wide-ranging, first-of-its-kind selection of Berryman’s correspondence with friends, loved ones, writers, and editors, showcasing the turbulent, fascinating life and mind of one of America’s major poets. The Selected Letters of John Berryman assembles for the first time the poet’s voluminous correspondence. Beginning with a letter to his parents in 1925 and concluding with a letter sent a few weeks before his death in 1972, Berryman tells his story in his own words. Included are more than 600 letters to almost 200 people—editors, family members, students, colleagues, and friends. The exchanges reveal the scope of Berryman’s ambitions, as well as the challenges of practicing his a...
