Book Description
This monograph is about predation in vertebrate animal community. The studies were done in the seminatural terrains with transitional mixed forest within the European forest zone in Belarus. The result part was organised as a top-down flow: First, the community characteristics related to predators were estimated. I presented data on predator species richness, population density and biomass with special attention paid to the changes in predator species diversity occurred during the last two centuries and particularly in connection with the American mink and raccoon dog naturalization. Then, the main features of predator food niches were given, and the structure of various predator guilds and size structure in predators were analysed. The next part of the monograph was devoted to examining of community-important factors acting in semi-natural terrains. Such factors affected either the whole community or its marked fragment. The last quite a large part of the monograph consisted of many chapters which present more or less essential results on different predator species, and stresses hot questions of their population ecology.

Book Description
Predation, one of the most dramatic interactions in animals' lives, has long fascinated ecologists. This volume presents carnivores, raptors and their prey in the complicated net of interrelationships, and shows them against the background of their biotic and abiotic settings. It is based on long-term research conducted in the best preserved woodland of Europe's temperate zone. The role of predation, whether limiting or regulating prey (ungulate, rodent, shrew, bird, and amphibian) populations, is quantified and compared to parts played by other factors: climate, food resources for prey, and availability of other potential resources for predators.

Book Description
This book addresses the fundamental issues of predator-prey interactions, with an emphasis on predation among arthropods, which have been better studied, and for which the database is more extensive than for the large and rare vertebrate predators. The book should appeal to ecologists interested in the broad issue of predation effects on communities.

Book Description
At last both ecology and evolution are covered in this study on the dynamics of size-structured populations. How does natural selection shape growth patterns and life cycles of individuals, and hence the size-structure of populations? This book will stimulate biologists to look into some important and interesting biological problems from a new angle of approach, concerning: - life history evolution, - intraspecific competition and niche theory, - structure and dynamics of ecological communities.

Book Description
Many animals regulate their population density by patterns of behavior that would be easy to explain if the forces of natural selection acted to optimize group properties. But Darwinian selection acts on individuals, not groups, and most simple theories have shown group selection to be too slow ever to oppose individual selection successfully. In this book Michael Gilpin presents a model, based on predator-prey dynamics, wherein nonlinear effects are important, so that small advantages to the selfish individual are nonlinearly amplified into disaster for his group. The result is that group selection can be rapid and powerful. Of course many instances of apparent group selection can be explained by kin selection; in other cases, close examination reveals that seemingly altruistic behavior directly benefits the individual genotype as well as the group. The value of the monograph is that it provides a robust model in which group selection, pure and unadulterated, can be seen to work.

Book Description
The chimpanzees are the closest living evolutionary relatives to our own species, Homo sapiens. As such, they have long exerted a fascination over those with an interest in human evolution, and what makes humans unique. Chrisophe Boesch and Hedwige Boesch-Acherman undertook an incredible observational study of a group of wild chimpanzees of the Tai forest in Cote D'Ivoire, spending some fifteen years in the West African jungle with them. This fascinating book is the result of these years of painstaking research among the chimps. Chimpanzee behavior is documented here in all its impressive diversity and variety. Aggression, territoriality, social structure and relationships, reproductive strategies, hunting, tool use - each of these is given its own chapter, along with topics such as chimp intelligence, life histories, and demography. The authors take care to place their observations within the broader context of research in behavioral ecology, and to compare and contrast their findings with other important work on chimpanzee groups, such as that by Jane Goodall. The book concludes with a summary chapter relating the chimpanzee findings to our understanding of human evolution. Combining careful scientific observation with a store of entertaining anecdotes, this is a lively and readable book. It also succeeds in shedding light on some of the central questions around the evolutionary relationships between the primates, and in particular the affinity between chimpanzees and humans. 'This is a major contribution to the study of the great apes, and a significant addition to debates about human/ape evolution. It has all the makings of a classic monograph.

Book Description
These charismatic mammals, which include dogs, cats, hyenas, weasels, mongooses, seals, sea lions and bears, have always held special importance to humans throughout history and continue to do so today. In recent decades, the emergence of new technologies has completely transformed our knowledge of how carnivorans interact with their environments and consequently reshaped our view of carnivoran ecology. This unique synthesis uses examples from a diverse and expanding carnivoran literature, drawing from all carnivoran families and spanning the world's oceans and continents, to produce a clearly written and richly illustrated book that reviews our current state of knowledge of carnivoran ecology. It addresses all levels of biological organization and function, from genes to enzymes, organisms, populations, and ecosystems. Special attention is given to how carnivoran species interact with their prey, each other, and humans. There is an emphasis on community interactions and their importance in carnivoran evolution, showing how evolutionary constraints (morphological, physiological, and behavioral) structure communities today. The book's approach is strongly comparative, contrasting herbivores with carnivores, predators with scavengers, and cats with dogs. Carnivorans play important roles in many high-profile conservation cases, either as species of concern or agents of endangerment, and their importance is demonstrated in both contexts. Carnivoran Ecology is an accessible advanced textbook aimed principally at senior undergraduate and graduate students taking courses in carnivore ecology, as well as a broad audience of professional academics (especially carnivore and mammalian biologists), researchers, and practitioners working in both governmental and non-governmental organizations. A significant secondary market will exist amongst the large amateur naturalist community including those wishing to explore the ecological and evolutionary links between domestic carnivorans (dogs, cats, ferrets etc.) and their wild counterparts.

Novel Aspects of Insect-Plant Interactions Edited by Pedro Barbosa and Deborah Letourneau This volume represents the forefront of two rapidly advancing areas of ecology: three-trophic-level interactions and the interdisciplinary field of chemical ecology The book focuses on the role of microorganisms as mediators of interactions between insects and plants, providing critical appraisal of studies and suggesting ways to integrate competing hypotheses of insect-plant dynamics. 1988 (0 471-83276-6) 362 pp. Arthropod Biological Control Agents and Pesticides Brian A. Croft Examining the effects of pesticides on predators and parasites and exploring methods for reducing negative impacts of pesticide use, this book focuses on the interaction of pesticides with entomophagous arthropods. It surveys the history of research in the field and discusses susceptibility assessment, lethal, sublethal, and ecological effects of pesticides, and selectivity, resistance, and resistance management. 1990 (0 471-81975-1) 723 pp. Lepidopteran Anatomy, John Eaton This single-source treatment on the anatomy of Lepidoptera provides a detailed exposition of its anatomy plus all its life stages, including the larva and adult forms of the exoskeleton, musculature, organ systems, and specialized structures.
