Download or read book Avian Biology written by Donald Farner and published by Elsevier. This book was released on 2012-12-02 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: Avian Biology,Volume VIII assesses selected aspects of avian biology. It is generally the conceptual descendant of Marshall's earlier treatise,"Biology and Comparative Physiology of Birds, but is more than simply a revision of it. This volume consists of two relatively lengthy, diverse chapters that focus on adaptive significance of coloniality in birds and fossil records of birds. In particular, this volume looks into group phenomena related to central place systems, that is, systems in which one or more individuals move to and from a centrally located place in the course of daily activities. It also addresses selective factors that have been suggested to explain why individuals should form colonies rather than disperse within the available foraging space. This book will be useful as a reference material for advanced students and instructors in this field of interest.

Download or read book Behavior of Marine Animals written by Joanna Burger and published by Springer Science & Business Media. This book was released on 2013-11-21 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: The maJonty of the chapters in this volume are structured to include a balance between literature review, original data, and synthesis. The research approaches taken by the authors are generallyof two kinds. One centers on the long-term, in-depth study of a single species in which many aspects of its natural history are examined in detail. The other is a comparative one which involves investigating particular questions by examining species or by comparing groups of species that may include taxonomic andjor ecological affinities. Most of the chapters concern obvious aspects of breeding behavior including habitat selection, the effects of age on breeding, communication, mating systems, synchrony of breeding activities, development of behavior, prefledging parental care, and postfledging parental care. Of these topics, many relate directly to the advantages and disadvantages of coloniality-a conspicuous behavior pattern in marine birds. As such, they provide para.picuou for the further study of coloniality and the social behaviorof many other animals. Other important areas of marine bird breeding behavior (such as courtship behavior, antipredator behavior, information transfer) have not been included because of space limitations. Since man's encroachment on the seashore and continental shelf poses certain threats to marine birds, a volume elucidating various aspects of their biology has multiple uses. As weil as being of value to ornithologists, the volume should be useful to managers involved with coastal planning.
Download or read book Geographic Variation Speciation and Clines MPB 10 Volume 10 written by John A. Endler and published by Princeton University Press. This book was released on 2020-03-31 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geographic Variation, Speciation and Clines explores the origins and development of geographic variation, divergence, and speciation. In particular it is concerned with genetic divergence as it is usually found on continents, among groups of populations isolated only by distance. Although earlier writers on this topic considered the effects of geography and dispersal, intense geographic differentiation and speciation were thought to require complete isolation. Professor Endler shows how geographic differentiation and speciation may develop in spite of continuous gene flow. Following a review of the diverse and scattered literature on gene flow and population differentiation, the author discusses the relationships among gene flow, dispersal, and migration. He then summarizes the factors which limit the geographic extent of gene flow, and those which allow steep clines to develop in the absence of barriers to gene flow. His analysis draws on examples from the field, experiments, and single- and multiple-locus models. The mechanism and conditions for parapatric speciation are presented: steepening clines, development into hybrid zones, and the evolution of sexual isolation. In the final chapter the author considers the interpretation of natural clines and the associated geographic patterns of subspecies and species.
Download or read book Avian Biology written by Donald S. Farner and published by Elsevier. This book was released on 2013-09-25 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: Avian Biology is a collection of papers that deals with biological aspects of birds such as their classification and habitat behavior. One paper reviews how birds are classified through practical systematics, study of fossils, and some of the problems encountered in the arrangement of major groups. Another paper discusses the origin and evolution of birds from their reptilian predecessors to their current evolutionary rates. Evolutionary rates vary depending on access to new habitats; if the environment is static, evolutionary rates can also slow down. One author discusses the inter-relations of sea birds with their marine environment, including coastal areas and the biological properties of the surface water. Another author describes the biology of desert birds relating to nomadism behavior and physical adaptations especially to the arid environment. The author also describes the cooling mechanism of these desert birds. Another paper evaluates the ecological aspect of behavior that includes foraging, habitat selection, mating, and flocking cohesion. Avian biologists, zoologists, and readers who have a general interest in birds will find this book useful.
Download or read book Current Ornithology written by Richard Johnston and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: If it is still true that more than 80% of the ornithologists in North America are primarily interested or engaged in ecological studies on birds (J. R. King and W. J. Bock, Final Report of the Workshop on a National Plan For Ornithology, 1978), then Volume 3 of Current Orni thology is preadapted for their consideration. All but one article in this volume are somehow concerned with the ecological aspects of the bi ology of birds. Variation in the scope of topical coverage is relatively broad, and includes conservation, reproduction, behavior, community structure, and evolutionary ecology. Three reviews concern the pervasive effects of man and industry on various bird populations of the world. Risebrough provides a de tailed description of the relationships between pesticides and bird pop ulations. Morrison ass es ses aspects of bird population numbers as in dicators of environmental change, and Temple outlines current research on endangered species. The broad spectrum of reproductive ecology of birds is variously treated in this volume. Jehl and Murray explore sexual selection and some of the resulting complexities in the evolution of sexual size di morphism, primarily in shorebirds. Lawton and Lawton are concerned with the relationships between social behavior and breeding systems in which variation is found in the age at which reproduction is first undertaken. Oring examines the wide-ranging variation in polyandrous breeding systems in birds, while Rohwer is concerned with adoption versus infanticide in birds, and their relationships to reproductive fit ness.
