Predator-Prey Interactions in the Fossil Record by Patricia H. Kelley,Michal Kowalewski,Thor A. Hansen Summary

From the Foreword: "Predator-prey interactions are among the most significant of all organism-organism interactions....It will only be by compiling and evaluating data on predator-prey relations as they are recorded in the fossil record that we can hope to tease apart their role in the tangled web of evolutionary interaction over time. This volume, compiled by a group of expert specialists on the evidence of predator-prey interactions in the fossil record, is a pioneering effort to collate the information now accumulating in this important field. It will be a standard reference on which future study of one of the central dynamics of ecology as seen in the fossil record will be built." (Richard K. Bambach, Professor Emeritus, Virginia Tech, Associate of the Botanical Museum, Harvard University)

Group Selection in Predator-prey Communities by Michael E. Gilpin Summary

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.

The Dynamics of Arthropod Predator-prey Systems by Michael Patrick Hassell Summary

In this study of arthropod predador-prey systems Michael Hassell shows how many of the components of predation may be simply modeled in order to reveal their effects on the overall dynamics of the interacting populations. Arthropods, particularly insects, make ideal subjects for such a study because their generation times are characteristically short and many have relatively discrete generations, inviting the use of difference equation models to describe population changes. Using analytical models framed in difference equations, Dr. Hassell is able to show how the detailed biological processes of insect predator-prey (including host-parasitoid) interactions may be understood. Emphasizing the development and subsequent stability analysis of general models, the author considers in detail several crucial components of predator-prey models: the prey's rate of increase as a function of density, non-random search, mutual interference, and the predator's rate of increase as a function of predator survival and fecundity. Drawing on the correspondence between the models and field and laboratory data, Dr. Hassell then discusses the practical implications for biological pest control and suggests how such models may help to formulate a theoretical basis for biological control practices.

Predator-Prey Dynamics by Michael R. Conover Summary

Humans, being visually oriented, are well versed in camouflage and how animals hide from predators that use vision to locate prey. However, many predators do not hunt by sight; they hunt by scent. This raises the question: do survival mechanisms and behaviors exist which allow animals to hide from these olfactory predators? If so, what are they, and how do they work? Predator-Prey Dynamics: The Role of Olfaction examines environmental as well as biological and behavioral elements of both predators and prey to answer gaps in our current knowledge of the survival dynamics of species. Beginning with a thorough look at the mechanics of olfaction, the author explains how predators detect, locate, and track their prey using odor trails on the ground or odor plumes in the air. Understanding the physics of airflow is the next step to understanding the potential for manipulating and masking scent. While a bush may conceal an animal visually from a predator, it will not protect an animal from a predator using olfaction. To hide from the latter, an animal needs to hide in locations where turbulence and updrafts will disperse its scent. The book addresses tradeoffs that animals must make given their dual needs to hide from predators and to procure food and water. Studies of mammalian and avian behavior provide examples on the actual use and efficacy of olfactory camouflage tactics. The book concludes with a redefinition of ecological terms based on the physics of airflow and a summary of the theory and implications of olfactory predator--prey dynamics. Introducing the mechanics of olfaction and its influence on the behavior of both predators and prey, Predator-Prey Dynamics: The Role of Olfaction presents a new perception of the world and enables us to understand and more effectively manage the delicate survival dynamics of animals in the wild.

From an Antagonistic to a Synergistic Predator Prey Perspective by Tore Johannessen Summary

From an Antagonistic to a Synergistic Predator Prey Perspective: Bifurcations in Marine Ecosystems is a groundbreaking reference that challenges the widespread perception that predators generally have a negative impact on the abundance of their prey, and it proposes a novel paradigm — Predator-prey Synergism — in which both predator and prey enhance abundance by their co-existence. Using this model, the text explains a number of issues that appear paradoxical in the case of a negative predator-prey relationship, including observed ecosystem bifurcations (regime shifts), ecosystem resilience, red tides in apparently nutrient depleted water, and the dominance of grazed phytoplankton over non-grazed species under high grazing pressure. This novel paradigm can also be used to predict the potential impact of global warming on marine ecosystems, identify how marine ecosystem may respond to gradual environmental changes, and develop possible measures to mitigate the negative impact of increasing temperature in marine ecosystems. This book approaches the long-standing question of what generates recruitment variability in marine fishes and invertebrates in an engaging and unique way that students and researchers in marine ecosystems will understand. Introduces a new paradigm, Predator-prey Synergism, as a building block on which to construct new ecological theories. It suggests that Predator-prey Synergism is important in some terrestrial ecosystems and is in agreement with the punctuated equilibria theory of evolution (i.e., stepwise evolution). Suggests a general solution to the recruitment puzzle in marine organisms Proposes a holistic hypothesis for marine spring blooming ecosystems by considering variability enhancing and variability dampening processes Asserts that fisheries will induce variability in marine ecosystems and alter the energy flow patterns in predictable ways

Analysis of vertebrate predator-prey community by Vadim Sidorovich Summary

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.

Predator: Prey to the Heavens by John Arcudi Summary

The world's attention is focused painfully on a brutal third-world civil war, a merciless sectarian conflict sparing neither soldier nor civilian, grandmother nor child. But amidst the terror and carnage, where great nations and powerful interests jockey for position and advantage, another blood feud rages in the shadows, one no more humane but decidedly less human. Two warring tribes from the stars have chosen Earth's killing fields as their arena, with each clan sworn to eradicate the other... and all who stand between them. Each is the other's prey, each the other's Predator. The hunt resumes as Dark Horse Books unleashes Predator once again into the graphic-fiction jungle. Features the creative team of writer John Arcudi (Aliens, B.P.R.D., Doom Patrol) and artist Javier Saltares (Aliens vs. Predator, Ghost Rider). * Collects the hit 2009 Predator miniseries.

Chimpanzee and Red Colobus by Craig Britton Stanford,Professor of Biological Sciences and Anthropology and Co-Director Jane Goodall Research Center Craig B Stanford,Richard W. Wrangham Summary

Our closest living relatives, the chimpanzees, are familiar enough--bright and ornery and promiscuous. But they also kill and eat their kin, in this case the red colobus monkey, which may say something about primate--even hominid--evolution. This book, the first long-term field study of a predator-prey relationship involving two wild primates, documents a six-year investigation into how the risk of predation molds primate society. Taking us to Gombe National Park in Tanzania, a place made famous by Jane Goodall's studies, the book offers a close look at how predation by wild chimpanzees--observable in the park as nowhere else--has influenced the behavior, ecology, and demography of a population of red colobus monkeys. As he explores the effects of chimpanzees' hunting, Craig Stanford also asks why these creatures prey on the red colobus. Because chimpanzees are often used as models of how early humans may have lived, Stanford's findings offer insight into the possible role of early hominids as predators, a little understood aspect of human evolution. The first book-length study in a newly emerging genre of primate field study, Chimpanzee and Red Colobus expands our understanding of not just these two primate societies, but also the evolutionary ecology of predators and prey in general.

Metapopulation Dynamics: Empirical and Theoretical Investigations by Michael Gilpin Summary

Metapopulation Dynamics: Empirical and Theoretical Investigations covers the 1989 proceedings of a metapopulation dynamics workshop held at Lammi Biological Station, Helsinki, Finland. It is divided into 18 chapters that cover various approaches to spatially structured population and community dynamics. After briefly discussing the history of metapopulation ideas and the major conceptual links, the book covers types of studies that have been conducted on single-species and multispecies metapopulations. Then, it examines the relationships between metapopulation dynamics, the equilibrium theory of island biogeography, and the dynamics of populations living in patchy environments. It further tackles practical issues and the links between metapopulation dynamics and landscape ecology, and between metapopulation dynamics and conservation biology. Chapters 4 and 5 present structured models describing changes in the number of individuals within patches and an empirical evaluation of local extinction in metapopulation studies. The subsequent chapters discuss several aspects of metapopulation, including dispersal and connectivity, colonization, conspecific attraction, extinction and isolation, and forest fragmentation. The latter chapters describe the concept of habitat fragmentation, the diversity and competition in metapopulations, the community collapse, and the effects of metapopulation studies in predator-prey systems.

Population Ecology by John H. Vandermeer,Deborah Esther Goldberg Summary

How can the future number of deer, agricultural pests, or cod be calculated based on the present number of individuals and their age distribution? How long will it take for a viral outbreak in a particular city to reach another city five hundred miles away? In addressing such basic questions, ecologists today are as likely to turn to complicated differential equations as to life histories--a dramatic change from thirty years ago. Population ecology is the mathematical backbone of ecology. Here, two leading experts provide the underlying quantitative concepts that all modern-day ecologists need. John Vandermeer and Deborah Goldberg show that populations are more than simply collections of individuals. Complex variables such as the size distribution of individuals and allotted territory for expanding groups come into play when mathematical models are applied. The authors build these models from the ground up, from first principles, using a much broader range of empirical examples--from plants to animals, from viruses to humans--than do standard texts. And they address several complicating issues such as age-structured populations, spatially distributed populations, and metapopulations. Beginning with a review of elementary principles, the book goes on to consider theoretical issues involving life histories, complications in the application of the core principles, statistical descriptions of spatial aggregation of individuals and populations as well as population dynamic models incorporating spatial information, and introductions to two-species interactions. Complemented by superb illustrations that further clarify the links between the mathematical models and biology, Population Ecology is the most straightforward and authoritative overview of the field to date. It will have broad appeal among undergraduates, graduate students, and practicing ecologists.
