Download or read book Evolutionary Theory and Processes Modern Perspectives written by Solomon Wasser and published by Springer Science & Business Media. 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. The integration between the molecular
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 Savanna Woody Plants and Large Herbivores written by Peter Frank Scogings and published by John Wiley & Sons. This book was released on 2019-09-30 with total page 794 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insights on current research and recent developments in understanding global savanna systems Increasingly recognized as synonymous with tropical grassy biomes, savannas are found in tropical and sub-tropical climates as well as warm, temperate regions of North America. Savanna Woody Plants and Large Herbivores examines the interactions between woody plants and browsing mammals in global savannas—focusing primarily on the C4 grassy ecosystems with woody components that constitute the majority of global savannas—and discusses contemporary savanna management models and applications. This much-needed addition to current research examines topics including the varying behavior of browsing mammals, the response to browsing by woody species, and the factors that inhibit forage intake. Contributions from an international team of active researchers and experts compare and contrast different savanna ecosystems, offering a global perspective on savanna functioning, the roles of soil and climate in resource availability and organism interaction, and the possible impacts of climate change across global savannas. Fills a gap in literature on savanna management issues, including biodiversity conservation and animal production Applies concepts developed in other biomes to future savanna research Complements contemporary books on savanna or large herbivore ecology Focuses on the woody component of savanna ecosystems and large herbivore interactions in savannas Compares tree-mammal systems of savannas and other eco-systems of temperate and boreal regions Provides numerous case studies of plant-mammal interactions from various savanna ecosystems Savanna Woody Plants and Large Herbivores is a valuable addition to those in fields such as ecology, wildlife and conservation biology, natural resource management, and environmental science.
Download or read book Natural Enemies written by Michael J. Crawley and published by John Wiley & Sons. This book was released on 2009-07-30 with total page 592 pages. 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.

Download or read book Trophic Cascades written by John Terborgh and published by Island Press. This book was released on 2013-06-25 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trophic cascades—the top-down regulation of ecosystems by predators—are an essential aspect of ecosystem function and well-being. Trophic cascades are often drastically disrupted by human interventions—for example, when wolves and cougars are removed, allowing deer and beaver to become destructive—yet have only recently begun to be considered in the development of conservation and management strategies. Trophic Cascades is the first comprehensive presentation of the science on this subject. It brings together some of the world’s leading scientists and researchers to explain the importance of large animals in regulating ecosystems, and to relate that scientific knowledge to practical conservation. Chapters examine trophic cascades across the world’s major biomes, including intertidal habitats, coastal oceans, lakes, nearshore ecosystems, open oceans, tropical forests, boreal and temperate ecosystems, low arctic scrubland, savannas, and islands. Additional chapters consider aboveground/belowground linkages, predation and ecosystem processes, consumer control by megafauna and fire, and alternative states in ecosystems. An introductory chapter offers a concise overview of trophic cascades, while concluding chapters consider theoretical perspectives and comparative issues. Trophic Cascades provides a scientific basis and justification for the idea that large predators and top-down forcing must be considered in conservation strategies, alongside factors such as habitat preservation and invasive species. It is a groundbreaking work for scientists and managers involved with biodiversity conservation and protection.
Download or read book Predator and Prey Population Dynamics and Distribution written by Julie Lynn McKnight and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. 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 Community Food Webs written by Joel E. Cohen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food webs hold a central place in ecology. They describe which organisms feed on which others in natural habitats. This book describes recently discovered empirical regularities in real food webs: it proposes a novel theory unifying many of these regularities, as well as extensive empirical data. After a general introduction, reviewing the empirical and theoretical discoveries about food webs, the second portion of the book shows that community food webs obey several striking phenomenological regularities. Some of these unify, regardless of habitat. Others differentiate, showing that habitat significantly influences structure. The third portion of the book presents a theoretical analysis of some of the unifying empirical regularities. The fourth portion of the book presents 113 community food webs. Collected from scattered sources and carefully edited, they are the empirical basis for the results in the volume. The largest available set of data on community food webs provides a valuable foundation for future studies of community food webs. The book is intended for graduate students, teachers and researchers primarily in ecology. The theoretical portions of the book provide materials useful to teachers of applied combinatorics, in particular, random graphs. Researchers in random graphs will find here unsolved mathematical problems.
