Download or read book Coloniality in the Cliff Swallow written by Charles R. Brown and published by University of Chicago Press. This book was released on 1996-07 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many animal species live and breed in colonies. Although biologists have documented numerous costs and benefits of group living, such as increased competition for limited resources and more pairs of eyes to watch for predators, they often still do not agree on why coloniality evolved in the first place. Drawing on their twelve-year study of a population of cliff swallows in Nebraska, the Browns investigate twenty-six social and ecological costs and benefits of coloniality, many never before addressed in a systematic way for any species. They explore how these costs and benefits are reflected in reproductive success and survivorship, and speculate on the evolution of cliff swallow coloniality. This work, the most comprehensive and detailed study of vertebrate coloniality to date, will be of interest to all who study social animals, including behavioral ecologists, population biologists, ornithologists, and parasitologists. Its focus on the evolution of coloniality will also appeal to evolutionary biologists and to psychologists studying decision making in animals.
Download or read book This Fragile Land written by Paul A. Johnsgard and published by U of Nebraska Press. This book was released on 1995-01-01 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Nebraska Sandhills is the largest area of sand dunes in the western hemisphere, covering an area about as large as Vermont, New Hampshire, and Rhode Island combined. Unlike most dunes, the Sandhills region supports an astonishing variety of wildlife. Sixty million years ago the area lay submerged in a vast inland sea. As the land lifted and the waters receded, the sandhills were formed, built upon a sandy floor above a sandy basement. Paul A. Johnsgard's appreciation for the region includes its evolution, a process that continues today making a very special place, patiently shaped by water, wind, and time. Sometimes 450 feet higher than their sloping valleys, the hills themselves are almost entirely covered with plants that manage to survive on an unstable substrate and in a climate of merciless heat and cold. They provide homes and resting places for rare species and sustain the livelihoods of a remarkable variety of people. Though firmly established in science, this book is an extended love letter to the Sandhills region and its people, plants, and animals. Johnsgard is now in his third decade of research in the Sandhills. This Fragile Land lets others see what he sees, a land with a fascinating range of geological, biological, and ecological vistas. Paul A. Johnsgard is Foundation Professor of the School of Biological Sciences at the University of Nebraska-Lincoln. Widely published throughout the English-speaking world, he has become a foremost authority on ornithology and bird behavior. His thirty-three books include Birds of the Great Plains, The Platte, Birds of the Rocky Mountains, Those of the Gray Wind, and Diving Birds of North America, all available from the University ofNebraska Press.

Download or read book Current Ornithology written by Val Nolan Jr. and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current Ornithology publishes authoritative, up-to-date, scholarly reviews of topics selected from the full range of current research in avian biology. Topics cover the spectrum from the molecular level of organization to population biology and community ecology. The series seeks especially to review 1) fields in which abundant recent literature will benefit from synthesis and organization, 2) newly emerging fields that are gaining recognition as the result of recent discoveries or shifts in perspective, and 3) fields in which students of vertebrates may benefit from comparisons of birds with other classes. All chapters are invited, and authors are chosen for their leadership in the subjects under review.
Download or read book The Ecology of Social Behavior written by C. N. Slobodchikoff and published by Elsevier. This book was released on 2013-10-22 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ecology of Social Behavior explores the relationships between ecology and the origins and maintenance of social behavior. The chapters in this book suggest that a consideration of ecological factors is necessary to any paradigm that tries to explain the origins and maintenance of social behavior. Most also suggest that there are some trade-offs between ecology, genetics, and phylogeny in the development and persistence of specific social systems. The book is organized into five parts. Part I provides an overview of the main themes covered in the present volume. Part II contains papers on ecological interactions, including variation in group sizes of forest primates, group foraging, and the origin of monogamy in mammals and fishes. Part III examines the ecology of social mammals. These include the ecological conditions for philopatry and the relationship of habitat variability to sociality in yellow-bellied marmots. Part IV focuses on the ecology of social birds while Part V deals with the ecology of social arthropods.
Download or read book An Introduction to Behavioural Ecology written by Nicholas B. Davies and published by John Wiley & Sons. This book was released on 2009-07-17 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: The third edition of this successful textbook looks again at the influence of natural selection on behavior - an animal's struggle to survive by exploiting resources, avoiding predators, and maximizing reproductive success. In this edition, new examples are introduced throughout, many illustrated with full color photographs. In addition, important new topics are added including the latest techniques of comparative analysis, the theory and application of DNA fingerprinting techniques, extensive new discussion on brood parasite/host coevolution, the latest ideas on sexual selection in relation to disease resistance, and a new section on the intentionality of communication. Written in the lucid style for which these two authors are renowned, the text is enhanced by boxed sections illustrating important concepts and new marginal notes that guide the reader through the text. This book will be essential reading for students taking courses in behavioral ecology. The leading introductory text from the two most prominent workers in the field. Second colour in the text. New section of four colour plates. Boxed sections to ilustrate difficult and important points. New larger format with marginal notes to guide the reader through the text. Selected further reading at the end of each chapter.

Download or read book Cooperation Among Animals written by Lee Alan Dugatkin and published by Oxford University Press, USA. This book was released on 1997 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the depiction of nature "red in tooth and claw," cooperation is actually widespread in the animal kingdom. Various types of cooperative behaviors have been documented in everything from insects to primates, and in every imaginable ecological scenario. Yet why animals cooperate is still a hotly contested question in literature on evolution and animal behavior. This book examines the history surrounding the study of cooperation, and proceeds to examine the conceptual, theoretical and empirical work on this fascinating subject. Early on, it outlines the four different categories of cooperation -- reciprocal altruism, kinship, group-selected cooperation and byproduct mutualism -- and ties these categories together in a single framework called the Cooperator's Dilemma. Hundreds of studies on cooperation in insects, fish, birds and mammals are reviewed. Cooperation in this wide array of taxa includes, but is not limited to, cooperative hunting, anti-predator behavior, foraging, sexual coalitions, grooming, helpers-at-the nest, territoriality, 'policing' behavior and group thermoregulation. Each example outlined is tied back to the theoretical framework developed early on, whenever the data allows. Future experiments designed to further elucidate a particular type of cooperation are provided throughout the book.

Download or read book A Handbook to the Swallows and Martins of the World written by Angela Turner and published by A&C Black. This book was released on 2010-06-30 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: This reference guide gives general details about the swallows and martins of the world. These include appearance, the basic coloration and differences between the sexes and immatures and the function of other areas of colouring. Several species within the same geographical area are often segregated by feeding in different habitats or at different heights or by eating different size-classes of insects. The two sub-families, one being the two river martins, the other containing about 72 species mainly in the genus hirundo, are dealt with, including their distribution and migration patterns. Feeding, courtship and breeding habits are considered, together with details of nesting sites, clutch size, incubation and life-span. Finally, the population sizes of the various species are examined, noting that whilst many have expanded their range by using man-made structures, forest species probably remain small and one species, the Red Sea swallow is known from only one specimen. The book follows the same approach, style and presentation as The Herons Handbook published in 1985. It is illustrated by the winner of the prestigious British Birds Illustrator of the Year Award and the author has contributed to many scientific papers and journals including BBC's Wildlife Magazine.
