Download or read book Social Predation written by Guy Beauchamp and published by Elsevier. This book was released on 2013-12-07 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: The classic literature on predation dealt almost exclusively with solitary predators and their prey. Going back to Lotka-Volterra and optimal foraging theory, the theory about predation, including predator-prey population dynamics, was developed for solitary species. Various consequences of sociality for predators have been considered only recently. Similarly, while it was long recognized that prey species can benefit from living in groups, research on the adaptive value of sociality for prey species mostly emerged in the 1970s. The main theme of this book is the various ways that predators and prey may benefit from living in groups. The first part focusses on predators and explores how group membership influences predation success rate, from searching to subduing prey. The second part focusses on how prey in groups can detect and escape predators. The final section explores group size and composition and how individuals respond over evolutionary times to the challenges posed by chasing or being chased by animals in groups. This book will help the reader understand current issues in social predation theory and provide a synthesis of the literature across a broad range of animal taxa. - Includes the whole taxonomical range rather than limiting it to a select few - Features in-depth analysis that allows a better understanding of many subtleties surrounding the issues related to social predation - Presents both models and empirical results while covering the extensive predator and prey literature - Contains extensive illustrations and separate boxes that cover more technical features, i.e., to present models and review results

Download or read book Game Theory and Animal Behavior written by Lee Alan Dugatkin and published by Oxford University Press. This book was released on 2000-03-23 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Game theory has revolutionized the study of animal behavior. The fundamental principle of evolutionary game theory--that the strategy adopted by one individual depends on the strategies exhibited by others--has proven a powerful tool in uncovering the forces shaping otherwise mysterious behaviors. In this volume, the first since 1982 devoted to evolutionary game theory, leading researchers describe applications of the theory to diverse types of behavior, providing an overview of recent discoveries and a synthesis of current research. The volume begins with a clear introduction to game theory and its explanatory scope. This is followed by a series of chapters on the use of game theory to understand a range of behaviors: social foraging, cooperation, animal contests, communication, reproductive skew and nepotism within groups, sibling rivalry, alternative life-histories, habitat selection, trophic-level interactions, learning, and human social behavior. In addition, the volume includes a discussion of the relations among game theory, optimality, and quantitative genetics, and an assessment of the overall utility of game theory to the study of social behavior. Presented in a manner accessible to anyone interested in animal behavior but not necessarily trained in the mathematics of game theory, the book is intended for a wide audience of undergraduates, graduate students, and professional biologists pursuing the evolutionary analysis of animal behavior.

Download or read book The New Ecology written by Oswald J. Schmitz and published by Princeton University Press. This book was released on 2018-12-18 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our species has transitioned from being one among millions on Earth to the species that is single-handedly transforming the entire planet to suit its own needs. In order to meet the daunting challenges of environmental sustainability in this epoch of human domination--known as the Anthropocene--ecologists have begun to think differently about the interdependencies between humans and the natural world. This concise and accessible book provides the best available introduction to what this new ecology is all about--and why it matters more than ever before. Oswald Schmitz describes how the science of ecology is evolving to provide a better understanding of how human agency is shaping the natural world, often in never-before-seen ways. The new ecology emphasizes the importance of conserving species diversity, because it can offer a portfolio of options to keep our ecosystems resilient in the face of environmental change. It envisions humans taking on new roles as thoughtful stewards of the environment to ensure that ecosystems have the enduring capacity to supply the environmental services on which our economic well-being--and our very existence--depend. It offers the ecological know-how to maintain and enhance our planet's environmental performance and ecosystem production for the benefit of current and future generations. Informative and engaging, The New Ecology shows how today's ecology can provide the insights we need to appreciate the crucial role we play in this era of unprecedented global environmental transition. -- Provided by publisher.

Download or read book Noninvasive Survey Methods for Carnivores written by Robert A. Long and published by Island Press. This book was released on 2012-09-26 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: The status of many carnivore populations is of growing concern to scientists and conservationists, making the need for data pertaining to carnivore distribution, abundance, and habitat use ever more pressing. Recent developments in “noninvasive” research techniques—those that minimize disturbance to the animal being studied—have resulted in a greatly expanded toolbox for the wildlife practitioner. Presented in a straightforward and readable style, Noninvasive Survey Methods for Carnivores is a comprehensive guide for wildlife researchers who seek to conduct carnivore surveys using the most up-to-date scientific approaches. Twenty-five experts from throughout North America discuss strategies for implementing surveys across a broad range of habitats, providing input on survey design, sample collection, DNA and endocrine analyses, and data analysis. Photographs from the field, line drawings, and detailed case studies further illustrate on-the-ground application of the survey methods discussed. Coupled with cutting-edge laboratory and statistical techniques, which are also described in the book, noninvasive survey methods are effi cient and effective tools for sampling carnivore populations. Noninvasive Survey Methods for Carnivores allows practitioners to carefully evaluate a diversity of detection methods and to develop protocols specific to their survey objectives, study area, and species of interest. It is an essential resource for anyone interested in the study of carnivores, from scientists engaged in primary research to agencies or organizations requiring carnivore detection data to develop management or conservation plans.

Download or read book Wildlife Conservation by Sustainable Use written by Herbert Prins and published by The Rosen Publishing Group. This book was released on 2000-08-31 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the major challenges of sustainable development is the interdisciplinary nature of the issues involved. To this end, a team of conservation biologists, hunters, tourist operators, ranchers, wildlife and land managers, ecologists, veterinarians and economists was convened to discuss whether wildlife outside protected areas in Africa can be conserved in the face of agricultural expansion and human population growth. They reached the unequivocal - if controversial - conclusion that wildlife can be an economic asset, especially in the African savannas, if this wildlife can be sustainably utilized through safari hunting and tourism. Using the African savannas as an example, Wildlife Conservation by Sustainable Use shows that in many instances sustainable wildlife utilization comprises an even better form of land use than livestock keeping. Even when population pressure is high, as in agricultural areas or in humid zones, and wild animal species can pose a serious cost to agriculture, these costs are mainly caused by small species with a low potential for safari hunting. Although ranching has a very low rate of return and is hardly ever profitable, the biggest obstacle to the model of sustainable wildlife use outlined in Wildlife Conservation by Sustainable Use is from unfair competition from the agricultural sector, such as subsidies and lack of taxation, resulting in market distortion for wildlife utilization. This book thus gives valuable evidence for a different way of working, providing arguments for removing such distortions and thereby facilitating financially sound land use and making it a rationally sound choice to conserve wildlife outside protected areas. The expert team of authors, most of whom came together at a workshop to thrash out the ideas that were then developed into the various chapters, has written a superb account of recent research on this complex subject, resulting in a book that is a major contribution to our understanding of sustainable use of land. The important conclusion is that wildlife conservation can be possible for landholders and local communities if they have a financial interest in protecting wildlife on their lands.

Download or read book The Ecology and Evolution of Inducible Defenses written by Ralph Tollrian and published by Princeton University Press. This book was released on 1999-01-17 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inducible defenses--those often dramatic phenotypic shifts in prey activated by biological agents ranging from predators to pathogens--are widespread in the natural world. Yet research on the inducible defenses used by vertebrates, invertebrates, and plants in terrestrial, marine, and freshwater habitats has largely developed along independent lines. Tollrian and Harvell bring together leading researchers from all fields to review common themes and explore emerging ideas. Contributors examine organisms as different as unicellular algae and higher vertebrates, and consider defenses ranging from immune systems to protective changes in morphology, behavior, chemistry, and life history.

Download or read book Biological Invasions in Marine Ecosystems written by Gil Rilov and published by Springer Science & Business Media. This book was released on 2008-11-12 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological invasions are considered to be one of the greatest threats to the integrity of most ecosystems on earth. This volume explores the current state of marine bioinvasions, which have been growing at an exponential rate over recent decades. Focusing on the ecological aspects of biological invasions, it elucidates the different stages of an invasion process, starting with uptake and transport, through inoculation, establishment and finally integration into new ecosystems. Basic ecological concepts - all in the context of bioinvasions - are covered, such as propagule pressure, species interactions, phenotypic plasticity, and the importance of biodiversity. The authors approach bioinvasions as hazards to the integrity of natural communities, but also as a tool for better understanding fundamental ecological processes. Important aspects of managing marine bioinvasions are also discussed, as are many informative case studies from around the world.

Download or read book A New Bio inspired Optimization Algorithm Based on the Self defense Mechanism of Plants in Nature written by Camilo Caraveo and published by Springer. This book was released on 2018-12-30 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a new meta-heuristic algorithm, inspired by the self-defense mechanisms of plants in nature. Numerous published works have demonstrated the various self-defense mechanisms (survival strategies) plants use to protect themselves against predatory organisms, such as herbivorous insects. The proposed algorithm is based on the predator–prey mathematical model originally proposed by Lotka and Volterra, consisting of two nonlinear first-order differential equations, which allow the growth of two interacting populations (prey and predator) to be modeled. The proposed meta-heuristic is able to produce excellent results in several sets of benchmark optimization problems. Further, fuzzy logic is used for dynamic parameter adaptation in the algorithm.

Download or read book Foraging written by David W. Stephens and published by University of Chicago Press. This book was released on 2008-09-15 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foraging is fundamental to animal survival and reproduction, yet it is much more than a simple matter of finding food; it is a biological imperative. Animals must find and consume resources to succeed, and they make extraordinary efforts to do so. For instance, pythons rarely eat, but when they do, their meals are large—as much as 60 percent larger than their own bodies. The snake’s digestive system is normally dormant, but during digestion metabolic rates can increase fortyfold. A python digesting quietly on the forest floor has the metabolic rate of thoroughbred in a dead heat. This and related foraging processes have broad applications in ecology, cognitive science, anthropology, and conservation biology—and they can be further extrapolated in economics, neurobiology, and computer science. Foraging is the first comprehensive review of the topic in more than twenty years. A monumental undertaking, this volume brings together twenty-two experts from throughout the field to offer the latest on the mechanics of foraging, modern foraging theory, and foraging ecology. The fourteen essays cover all the relevant issues, including cognition, individual behavior, caching behavior, parental behavior, antipredator behavior, social behavior, population and community ecology, herbivory, and conservation. Considering a wide range of taxa, from birds to mammals to amphibians, Foraging will be the definitive guide to the field.

Download or read book Predator and Prey written by Christopher Golden and published by Simon and Schuster. This book was released on 2002-11-15 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: they're real, and they're here.... Prowlers Jack Dwyer can see dead people, and they can see him. In fact, he has made a regular practice of communicating with his dead friend Artie from the Ghostlands, where Artie's spirit wanders. Artie helps keep Jack apprised of Prowler activity, and Jack, along with his sister, Courtney, and their friends, tracks these violent killers down and stops them. Artie's latest piece of information is startling: a vicious beast known as the Ravenous is stalking the Ghostlands. It's Jack's turn to help the endangered spirits -- without endangering himself. He's got some help from a woman who is not quite as young as she seems -- but the Ravenous has got his scent. Meanwhile Jasmine, pack leader and dangerous hunter, has issued a hit on Jack and his friends. But if he consults his allies in the Ghostlands for help, Jack will attract the Ravenous. It's a double-edged sword -- and Jack's not sure he can avoid being cut....

Download or read book Escaping From Predators written by William E. Cooper, Jr and published by Cambridge University Press. This book was released on 2015-05-28 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: When a predator attacks, prey are faced with a series of 'if', 'when' and 'how' escape decisions – these critical questions are the foci of this book. Cooper and Blumstein bring together a balance of theory and empirical research to summarise over fifty years of scattered research and benchmark current thinking in the rapidly expanding literature on the behavioural ecology of escaping. The book consolidates current and new behaviour models with taxonomically divided empirical chapters that demonstrate the application of escape theory to different groups. The chapters integrate behaviour with physiology, genetics and evolution to lead the reader through the complex decisions faced by prey during a predator attack, examining how these decisions interact with life history and individual variation. The chapter on best practice field methodology and the ideas for future research presented throughout, ensure this volume is practical as well as informative.
