Download or read book Acute But Not Chronic Effects of Predator Presence on Song Sparrow Melospiza Melodia Singing Behaviour written by Anne Margaret Ellison and published by . This book was released on 2015 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North American Breeding Bird Survey (BBS) indicates long term declines for many songbird species. As surveys are based partially on auditory cues, a change in the song rate could affect survey numbers. Here I test the hypothesis that the danger posed by raptor presence affects songbird singing behaviour. I measured the singing behaviour of song sparrows (Melospiza melodia) in relation to both chronic (active Cooper's hawk Accipiter cooperii nest nearby) and acute (playback of hawk calls) predator exposure. I found no evidence for a chronic effect, but song sparrows reduced their singing rate by 37.5% in the minutes after acute exposure. There was no reduction in response to control playbacks. My results suggest that the BBS census declines of songbirds could potentially be partially accounted for by a reduction in song as raptor populations recovered after the 1973 ban on DDT.

Download or read book The Effects of Habituation on Boldness of Urban and Rural Song Sparrows Melospiza Melodia written by Taylor Elaine Fossett and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: As urban development continues to dominate landscapes across the United States, wildlife species are changing their behavior in many ways. Urban animals are often bolder, or less fearful of new stimuli, than rural animals. While natural selection and adaptation can drive behavioral changes in urban animals, other factors, such as learning or habituation, can also lead to behavioral modifications. Habituation may play an important role, if urban individuals learn through repeated exposure that humans do not represent a threat. To determine how repeated human exposure affects song sparrow (Melospiza melodia) populations in an urban and rural habitat, I measured boldness as flight initiation distance (FID), after repeated exposure to a nonthreatening human subject. FID measures the distance between human and bird, at which the bird flies away in fear of disturbance or predation. I collected FID data on male song sparrows in an urban and rural environment over 5 consecutive days. I found that after 5 days of successive trials, FID was individually repeatable in both urban and rural populations. Urban birds had consistently lower FID than their rural counterparts. I also found that FID went down over 5 days of repeated trials in the rural populations, but not the urban. These results suggest that habituation can occur quickly in rural birds and account for the greater boldness we typically see in urban populations.

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 an abundant recent literature will benefit from synthesis and organization, or (2) newly emerging fields that are gaining recognition as the result of recent discoveries or shifts in perspective, or (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 Avian Immunology written by Bernd Kaspers and published by Academic Press. This book was released on 2012-12-02 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of Avian Immunology provides an up-to-date overview of the current knowledge of avian immunology. From the ontogeny of the avian immune system to practical application in vaccinology, the book encompasses all aspects of innate and adaptive immunity in chickens. In addition, chapters are devoted to the immunology of other commercially important species such as turkeys and ducks, and to ecoimmunology summarizing the knowledge of immune responses in free-living birds often in relation to reproductive success. The book contains a detailed description of the avian innate immune system, encompassing the mucosal, enteric, respiratory and reproductive systems. The diseases and disorders it covers include immunodepressive diseases and immune evasion, autoimmune diseases, and tumors of the immune system. Practical aspects of vaccination are examined as well. Extensive appendices summarize resources for scientists including cell lines, inbred chicken lines, cytokines, chemokines, and monoclonal antibodies. The world-wide importance of poultry protein for the human diet, as well as the threat of avian influenza pandemics like H5N1 and heavy reliance on vaccination to protect commercial flocks makes this book a vital resource. This book provides crucial information not only for poultry health professionals and avian biologists, but also for comparative and veterinary immunologists, graduate students and veterinary students with an interest in avian immunology. With contributions from 33 of the foremost international experts in the field, this book provides the most up-to-date review of avian immunology so far Contains a detailed description of the avian innate immune system reviewing constitutive barriers, chemical and cellular responses; it includes a comprehensive review of avian Toll-like receptors Contains a wide-ranging review of the "ecoimmunology" of free-living avian species, as applied to studies of population dynamics, and reviews methods and resources available for carrying out such research

Download or read book Feeding in Vertebrates written by Vincent Bels and published by Springer. This book was released on 2019-04-23 with total page 865 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides students and researchers with reviews of biological questions related to the evolution of feeding by vertebrates in aquatic and terrestrial environments. Based on recent technical developments and novel conceptual approaches, the book covers functional questions on trophic behavior in nearly all vertebrate groups including jawless fishes. The book describes mechanisms and theories for understanding the relationships between feeding structure and feeding behavior. Finally, the book demonstrates the importance of adopting an integrative approach to the trophic system in order to understand evolutionary mechanisms across the biodiversity of vertebrates.

Download or read book Evolutionary Quantitative Genetics written by Derek A. Roff and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impetus for this book arose out of my previous book, The Evolution of Life Histories (Roff, 1992). In that book I presented a single chapter on quanti tative genetic theory. However, as the book was concerned with the evolution of life histories and traits connected to this, the presence of quantitative genetic variation was an underlying theme throughout. Much of the focus was placed on optimality theory, for it is this approach that has proven to be extremely successful in the analysis of life history variation. But quantitative genetics cannot be ig nored, because there are some questions for which optimality approaches are inappropriate; for example, although optimality modeling can address the ques tion of the maintenance of phenotypic variation, it cannot say anything about genetic variation, on which further evolution clearly depends. The present book is, thus, a natural extension of the first. I have approached the problem not from the point of view of an animal or plant breeder but from that of one interested in understanding the evolution of quantitative traits in wild populations. The subject is large with a considerable body of theory: I generally present the assumptions underlying the analysis and the results, giving the relevant references for those interested in the intervening mathematics. My interest is in what quantitative genetics tells me about evolutionary processes; therefore, I have concentrated on areas of research most relevant to field studies.

Download or read book Avian Energetics and Nutritional Ecology written by C. Carey and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: A symposium held in 1973 chaired and organized by William R. Dawson was the first major attempt to summarize and synthesize the existing information in the then emerging field of avian energetics. The symposium featured papers by James R. King, William A. Calder III, Vance A. Tucker, and Robert E. Ricklefs and com mentaries by George A. Bartholomew, S. Charles Kendeigh, and Eugene P. Odum. The proceedings of the symposium, Avian Energetics (Paynter 1974), played a critical role in stimulating interest and research in the field of avian energetics. Some twenty-odd years later, we are making another attempt to summarize the information in the field of avian energetics. Some obvious differences exist be tween its predecessor and this volume. Numerous improvements in methodology, such as the use of doubly labeled water to estimate metabolism in free-living birds, now allow researchers to ask questions that could not be addressed previ ously. Second, consideration of nutrition is now inseparable from that of energet ics. This merger is necessary not only because food intake is the source of both en ergy and nutrients but also because one or more nutrients, rather than energy, can be limiting for a given species in a particular instance. Finally, the study of ener getics and nutritional ecology, particularly in birds and mammals, has grown so dramatically that a single volume can now only partially cover the range of possi ble topics and can catalogue only a sampling of all the studies on the subject.

Download or read book Predator Recognition in Birds written by Roman Fuchs and published by Springer. This book was released on 2019-03-27 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SpringerBrief answers the question on how birds recognize their predators using multidisciplinary approaches and outlines paths of the future research of predator recognition. A special focus is put on the role of key features to discriminate against predators and non-predators. The first part of the book provides a comprehensive review of the mechanisms of predator recognition based on classical ethological studies in untrained birds. The second part introduces a new view on the topic treating theories of cognitive ethology. This approach involves examination of conditioned domestic pigeons and highlights the actual abilities of birds to recognize and categorize.
