Book excerpt: The landscape in which common weasels ('Mustela nivalis vulgaris '), and field voles ('Microtus agrestis') live and weasel dispersal ability affect population dynamics in Kielder Forest, Northern England. Grassed clear-cuts (the primary habitat for voles and weasels) within Kielder are not 'islands' but in fact habitat patches that are highly connected by linear features. It is possible that the mobility of common weasels in Kielder Forest may cause decreased amplitude of the vole population cycle. Small mustelids should not experience increased energetic cost and/or mortality when dispersing to exploitable patches because they are not moving through unsuitable, non-prey habitat. My findings suggest that connectivity between suitable habitat patches and specialist predator dispersal ability are important variables that require consideration when researching the impact of predators on small rodent dynamics. A bait station database was used to identify carnivore associations in the Cape Breton Highlands, NovaScotia. Carnivore abundance and distribution may be influenced by interference and resource competition. Species association patterns were used to infer interspecific interactions. Red fox (' Vulpes vulpes') were absent from bait stations with either coyotes ('Canis latrans') or lynx ('Felis lynx'). It may be that red foxes were not present in these areas due to different habitat preferences, active avoidance of areas where lynx or coyote are abundant, or high predation of foxes. A positive species association was found for red fox and short-tailed weasel ('Mustela erminea'). This positive association may be the result of high niche overlap between foxes and weasels. It is likely that interspecific interactions, especially interference competition, shape the carnivore community of the Cape Breton Highlands. Further research is required for red foxes, as they may be severely affected by competition.

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

Available in PDF, EPUB and Kindle. Book excerpt: When assuming the task of preparing a book such as this, one inevitably wonders why anyone would want to read it. I have always sympathized with Charles Elton's trenchant observation in his 1927 book that 'we have to face the fact that while ecological work is fascinating to do, it is unbearably dull to read about . . . ' And yet several good reasons do exist for producing a small volume on predation. The subject is interesting in its own right; no ecologist can deny that predation is one of the basic processes in the natural world. And the logical roots for much currently published reasoning about predation are remarkably well hidden; if one must do research on the subject, it helps not to be forced to start from first principles. A student facing predator-prey interactions for the first time is confronted with an amazingly diverse and sometimes inaccessible literature, with a ratio of wheat to chaff not exceeding 1: 5. A guide to the perplexed in this field does not exist at present, and I hope the book will serve that function. But apart from these more-or-Iess academic reasons for writing the book, I am forced to it by my conviction that predators are important in the ecological scheme. They playa critical role in the biological control of insects and other pests and are therefore of immediate economic concern.

Available in PDF, EPUB and Kindle. Book excerpt: This book is about disease and death. It is an ecologist's view of Darwin's vivid evocation of Nature, red in tooth and claw. An international team of authors examines broad patterns in the population biology of natural enemies, and addresses general questions about the role of natural enemies in the population dynamics and evolution of their prey. For instance, how do large natural enemies like wolves differ from small natural enemies like bacterial diseases in their effects on prey abundance? Is it better to chase after prey, or sit and wait for it to come to you? How should prey behave in order to minimize the risk of being eaten? The answers are all in this fascinating senior undergraduate/postgraduate text.

This book was released on 2012-12-06 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: A book blending evolution and trophic dynamics, taking into account recent advances in both behavioral and population ecology, is long overdue. A central objective of this book is to consider whether adaptive behavioral decisions on the individual organism level might tend to stabilize trophic interactions. A second major goal of the book is to explore the implications of presumably adaptive behaviors on trophic dynamics and the implications of trophic dynamics for the evolution of adaptive behaviors. All evolutionary biologists, ecologists, and behavioral ecologists should find this exciting volume essential reading.

Book excerpt: Animal Vigilance builds on the author's previous publication with Academic Press (Social Predation: How Group Living Benefits Predators and Prey) by developing several other themes including the development and mechanisms underlying vigilance, as well as developing more fully the evolution and function of vigilance. Animal vigilance has been at the forefront of research on animal behavior for many years, but no comprehensive review of this topic has existed. Students of animal behavior have focused on many aspects of animal vigilance, from models of its adaptive value to empirical research in the laboratory and in the field. The vast literature on vigilance is widely dispersed with often little contact between models and empirical work and between researchers focusing on different taxa such as birds and mammals. Animal Vigilance fills this gap in the available material. - Tackles vigilance from all angles, theoretical and empirical, while including the broadest range of species to underscore unifying themes - Discusses several newer developments in the area, such as vigilance copying and effect of food density - Highlights recent challenges to assumptions of traditional models of vigilance, such as the assumption that vigilance is independent among group members, which is reviewed during discussion of synchronization and coordination of vigilance in a group - Written by a top expert in animal vigilance

This book was released on 2020-03-31 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1998-12-31 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents some of the most recent dramatic results of molecular, genomic, and organismal evolutionary processes. It represents analyses, experiments, observations, reviews, discussions and forecasts of evolutionary theory comprising both novel methods and results, reanalyzed and reviewed data sets based on comparative, experimental, and theoretical studies utilizing model organisms across phylogeny, including bacteria, fungi, plants, animals and humans. It elucidates the revolution in molecular biology that ushered in our understanding of the evolutionary process over time and space. The topics discussed include major problems of evolutionary theory concerning origins, phylogeny, relative importance of evolutionary forces, structure and function, adaptation and speciation in space and time in changing and stressful environments. A major emerging generalization is the nonrandomness of genome structure highlighting the importance of natural selection as a major organizing evolutionaryforce not only at the phenotypic level, but most importantly at the interlinked genotypic molecular level.

Download or read book The Ecology of Predation at the Microscale written by Edouard Jurkevitch and published by Springer Nature. This book was released on 2020-06-29 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book will provide an update on our understanding of predator-prey through the prism of ecology, physiology, molecular biology, and mathematical modelling. The integration of these different perspectives while focusing on the microbial realm will highlight the importance of scale in ecological interactions, and their importance in applications. This book should thereby contribute to theoretical as well as to applied ecologists and microbiologists. Furthermore, the detailed but amenable chapters could serve as the basis of teaching advanced courses in (microbial) ecology and environmental microbiology.This work is a collection of articles that discuss microbial predation from a variety of perspectives. It provides the readers a concise resource describing factors that are critical for several different predatory microbes, including Myxobacterium spp. and Bdellovibrio-and-like organisms (BALOs), including the mechanisms involved, ecological conditions that adversely impact it and potential applications in aquaculture and bioproduction. The first half of this collection focuses more on ecological aspects of predation, with in-depth discussions on “wolf pack” predators, the presence and activities of predators in waste-water treatment plants and the role of intraguild predatory relationships, i.e., when two different predators are competing for a single prey but also interact with one another. The reader will gain a deeper understanding of the predatory mechanisms involved and their ecological roles. In the latter half, emphasis is given more to the application and limitations of predators. In addition to discussing secondary metabolite production within different microbial predators, the readers will also learn how predators are being used to purify secondary metabolites from prey. This section also discusses the expanding and promising role of predation in aquaculture, focusing on the application of predators to reduce pathogenic populations, but includes some important caveats for young researchers to consider and follow when working with Bdellovibrio. This work is written for both experienced researchers already in the field and for young scientists who are captivated by the thought of predation at the microscale and its growing importance within a wide-array of fields.
