Download or read book Geographic Variation in Behavior written by Susan A. Foster and published by Oxford University Press. This book was released on 1999-03-04 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies of animal behavior often assume that all members of a species exhibit the same behavior. Geographic Variation in Behavior shows that, on the contrary, there is substantional variation within species across a wide range of taxa. Including work from pioneers in the field, this volume provides a balanced overview of research on behavioral characteristics that vary geographically. The authors explore the mechanisms by which behavioral differences evolve and examine related methodological issues. Taken together, the work collected here demonstrates that genetically based geographic variation may be far more widespread than previously suspected. The book also shows how variation in behavior can illuminate both behavioral evolution and general evolutionary patterns. Unique among books on behavior in its emphasis on geographic variation, this volume is a valuable new resource for students and researchers in animal behavior and evolutionary biology.
Download or read book Peterson Reference Guide to Sparrows of North America written by Rick Wright and published by Peterson Reference Guides. This book was released on 2019-03-19 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sparrows are as complicated as they are common. This is an essential guide to identifying 76 kinds, along with a fascinating history of human interactions with them. What, exactly, is a sparrow? All birders (and many non‑birders) have essentially the same mental image of a pelican, a duck, or a flamingo, and a guide dedicated to waxwings or kingfishers would need nothing more than a sketch and a single sentence to satisfactorily identify its subject. Sparrows are harder to pin down. This book covers one family (Passerellidae), which includes towhees and juncos, and 76 members of the sparrow clan. Birds have a human history, too, beginning with their significance to native cultures and continuing through their discovery by science, their taxonomic fortunes and misfortunes, and their prospects for survival in a world with ever less space for wild creatures. This book includes not just facts and measurements, but stories--of how birds got their names and how they were discovered--of their entanglement with human history.

This beautiful and authoritative book is a must for the library of all keen birders living in and visiting North America. Species accounts include discussions of species': * Identification * Measurements * Voice * Habitat * Ecology * Nesting biology * Distribution * Taxonomy * Geographic variations * Historical and present status
Download or read book Animal Cognition in Nature written by Russell P. Balda and published by Academic Press. This book was released on 1998-09-09 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, the editors bring together results from studies on all kinds of animals to show how thinking on many behaviors as truly cognitive processes can help us to understand the biology involved. Taking ideas and observations from the while range of research into animal behavior leads to unexpected and stimulating ideas. A space is created where the work of field ecologists, evolutionary ecologists and experimental psychologists can interact and contribute to a greater understanding of complex animal behavior, and to the development of a new and coherent field of study.
Download or read book Current Ornithology written by Richard Johnston and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is not often that a century of scholarly activity breaks conveniently into halves, but ornithology of the first half of the 20th century is clearly different from that of the second half. The break actually can be marked in 1949, with the appearance of Meyer and Schuz's Ornithologie ais Biologische Wissenschaft. Prior to this, ornithologists had tended to speak mostly to other ornithologists, experiments (the testing of hy potheses) were uncommon, and a concern for birds as birds was the dominant thread in our thinking. Subsequent to 1949, ornithologists have tended to become ever more professional in their pursuits and to incorporate protocols of experimental biology into their work; more importantly perhaps, they have begun to show a concern for birds as agencies for the study of biology. Many of the most satisfying of recent ornithological studies have come from reductionist research ap proaches, and have been accomplished by specialists in such areas as biochemistry, ethology, genetics, and ecology. A great many studies routinely rely on statistical hypothesis testing, allowing us to come to conclusions unmarred by wishful thinking. Some of us are ready to tell the world that we are a "hard" science, and perhaps that time is not so very far off for most of us. Volume 2 examines several solid examples of late 20th-century ornithology.
Download or read book Acoustic Communication in Birds written by Kroodsma and published by Elsevier. This book was released on 1983-05-10 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acoustic Communication in Birds, Volume 2: Song Learning and Its Consequences investigates acoustic communication in birds, with emphasis on song learning and its consequences. Some issues in the study of bird sounds are discussed, with particular reference to evolutionary considerations. The ontogeny of acoustic behavior in birds is also considered, along with sound production, neural control of song, and auditory perception. Comprised of nine chapters, this volume begins with an introduction to the nature, extent, and evolution of vocal learning in birds. Several well-documented examples in which vocal development appears to proceed independently of audition (and therefore independently of vocal learning) are presented, together with aspects of selective vocal learning; the timing of vocal learning; and selective forces that may have promoted the evolution of vocal learning in birds. Subsequent chapters explore the role of subsong and plastic song in the vocal learning process; the function and evolution of avian vocal mimicry; the ecological and social significance of duetting in birds; and microgeographic and macrogeographic variation in the acquired vocalizations of birds. The book also examines genetic population structure and vocal dialects in Zonotrichia (Emberizidae). This monograph will be of interest to ornithologists, evolutionary biologists, and zoologists, as well as to students of communication and bioacoustics.
Download or read book Avian Genetics written by F. Cooke and published by Academic Press. This book was released on 2013-09-24 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: Avian Genetics: A Population and Ecological Approach is a collection of papers that deals with the study of birds in relation to the synthetic theory of evolution. This book studies the ecology, demography, behavior, and geographical distribution of birds; the text also discusses quantitative, chromosomal, biochemical, and population genetics. Part I reviews the various genetic interactions, including an analysis of DNA sequence variation. The different and newer techniques are compared such as the works of Sibley, Quinn, and White. Part II describes the molding genetic variation and covers topics such as inbreeding; gene flow and the genetic structure of populations; non-random mating; and the process of selection in natural populations of birds. Part III covers actual genetic case histories, including quantitative ecological genetics of great tits; genetic evolution of house sparrows; and presentation of evidence for sexual selection by female choice in the Arctic Skua. This book also presents future research in subjects such as the neutrality-selection controversy or genetics and conservation. This text can be beneficial for ecologists, ornithologists, animal conservationists, and population biologists studying birds.

Download or read book Neurohistological Studies of the Hypothalamo Hypophysial System of Zonotrichia leucophrys gambelii Aves Passeriformes written by A. Oksche and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: The anatomical description of the hypothalamo-hypophysial system of the White-crowned Sparrow, Zonotrichia leucophrys gambelii, as presented in this treatise, is by no means of definitive nature. Research in this area, in our own laboratories and elsewhere, continues at such a pace and is sufficiently in flux as to preclude the possibility of definitive morphological and functional conclu sions at this time. Nevertheless, we do believe that there is now some genuinely heuristic value in a presentation of our neuroanatomical material. Most of this material is derived from the above-mentioned species which has received primary attention in our experimental investigations. In the course of our studies, it has become clear that the hypothalamo hypophysial system of birds has attained morphological differentiation and spe cialization as extensive as that of mammals. In order not to lose sight of the basic pattern of the system, comparative aspects must be brought into con sideration. With this in mind we emphasize the fundamental contributions of Huber and Crosby, Kuhlenbeck, Benoit, Assenmacher and vVingstrand. The ana tomical nomenclature of the avian hypothalamus has been critically examined and rationalized, to the extent possible, from a comparative view-point. In recent years this nomenclature has developed in such an independent and isolated manner that the confusion created can no longer be ignored. 'Ve dedicate our treatise to the memory of Professor Ernst Scharrer who originally stimulated our investigations.

Download or read book Birds New to Science written by David Brewer and published by Bloomsbury Publishing. This book was released on 2018-01-26 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amazing as it might sound, ornithologists are still discovering several bird species each year that are completely new to science. These aren't all obscure brown birds on tiny islands – witness the bizarre Bare-faced Bulbul from Laos (2009), spectacular Araripe Manakin from Brazil (1998), or gaudy Bugun Liocichla from north-east India (2006). Birds New to Science documents more than half a century of these remarkable discoveries, covering around 300 species. Each account includes the story of discovery, a brief description of the bird (many with accompanying photographs), and details of what is known about its biology, range and conservation status. Written in an engaging style, this is a rich reference to an incredible era of adventure in ornithology.
