Available in PDF, EPUB and Kindle. Book excerpt: Squirrels of the World, written by scientists with more than 100 years of collective experience studying these popular mammals, is the first comprehensive examination of all 285 species of squirrels worldwide. The authors reveal virtually every detail of the family Sciuridae, which includes ground squirrels, tree squirrels, flying squirrels, prairie dogs, and chipmunks. Each species—from the familiar gray squirrel of American backyards to the exotic and endangered woolly flying squirrel of Pakistan—is described in a detailed account that includes distinguishing characteristics, ecology, natural history, conservation status, and current threats to its existence. Squirrels of the World includes • stunning color photographs that document rare and unusual squirrels as well as common varieties• evolution, morphology, ecology, and conservation status• colorful range maps marking species distribution• images of the skull of each genus of squirrel• extensive references -- Lawrence Heaney, Curator and Head of the Division of Mammals, The Field Museum (Chicago)

Download or read book Rodent Societies written by Jerry O. Wolff and published by University of Chicago Press. This book was released on 2008-09-15 with total page 627 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rodent Societies synthesizes and integrates the current state of knowledge about the social behavior of rodents, providing ecological and evolutionary contexts for understanding their societies and highlighting emerging conservation and management strategies to preserve them. It begins with a summary of the evolution, phylogeny, and biogeography of social and nonsocial rodents, providing a historical basis for comparative analyses. Subsequent sections focus on group-living rodents and characterize their reproductive behaviors, life histories and population ecology, genetics, neuroendocrine mechanisms, behavioral development, cognitive processes, communication mechanisms, cooperative and uncooperative behaviors, antipredator strategies, comparative socioecology, diseases, and conservation. Using the highly diverse and well-studied Rodentia as model systems to integrate a variety of research approaches and evolutionary theory into a unifying framework, Rodent Societies will appeal to a wide range of disciplines, both as a compendium of current research and as a stimulus for future collaborative and interdisciplinary investigations.
Download or read book Sexual Selection written by Malte Andersson and published by Princeton University Press. This book was released on 2019-12-31 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Bright colors, enlarged fins, feather plumes, song, horns, antlers, and tusks are often highly sex dimorphic. Why have males in many animals evolved more conspicuous ornaments, signals, and weapons than females? How can such traits evolve although they may reduce male survival? Such questions prompted Darwin's perhaps most scientifically controversial idea--the theory of sexual selection. It still challenges researchers today as they try to understand how competition for mates can favor the variety of sex-dimorphic traits. Reviewing theoretical and empirical work in this very active field, Malte Andersson, a leading contributor himself, provides a major up-to-date synthesis of sexual selection. The author describes the theory and its recent development; examines models, methods, and empirical tests; and identifies many unsolved problems. Among the topics discussed are the selection and evolution of mating preferences; relations between sexual selection and speciation; constraints on sexual selection; and sex differences in signals, body size, and weapons. The rapidly growing study of sexual selection in plants is also reviewed. This volume will interest students, teachers, and researchers in behavioral ecology and evolutionary biology.

Download or read book Mammals of Mexico written by Gerardo Ceballos and published by JHU Press. This book was released on 2014-01-15 with total page 976 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most comprehensive reference on Mexico's diverse mammalian fauna. Mammals of Mexico is the first reference book in English on the more than 500 types of mammal species found in the diverse Mexican habitats, which range from the Sonoran Desert to the Chiapas cloud forests. The authoritative species accounts are written by a Who’s Who of experts compiled by famed mammalogist and conservationist Gerardo Ceballos. Ten years in the making, Mammals of Mexico covers everything from obscure rodents to whales, bats, primates, and wolves. It is thoroughly illustrated with color photographs and meticulous artistic renderings, as well as range maps for each species. Introductory chapters discuss biogeography, conservation, and evolution. The final section of the book illustrates the skulls, jaws, and tracks of Mexico’s mammals. This unparalleled collection of scientific information on, and photographs of, Mexican wildlife belongs on the shelf of every mammalogist, in public and academic libraries, and in the hands of anyone curious about Mexico and its wildlife.
Download or read book The Evolution of Senescence in the Tree of Life written by Richard P. Shefferson and published by Cambridge University Press. This book was released on 2017-02-23 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: The existing theories on the evolution of senescence assume that senescence is inevitable in all organisms. However, recent studies have shown that this is not necessarily true. A better understanding of senescence and its underlying mechanisms could have far-reaching consequences for conservation and eco-evolutionary research. This book is the first to offer interdisciplinary perspectives on the evolution of senescence in many species, setting the stage for further developments. It brings together new insights from a wide range of scientific fields and cutting-edge research done on a multitude of different animals (including humans), plants and microbes, giving the reader a complete overview of recent developments and of the controversies currently surrounding the topic. Written by specialists from a variety of disciplines, this book is a valuable source of information for students and researchers interested in ageing and life history traits and populations.

Download or read book Animal Vigilance written by Guy Beauchamp and published by Academic Press. This book was released on 2015-06-29 with total page 267 pages. Available in PDF, EPUB and Kindle. 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
