R5,226 Discovery Miles 52 260 Ships in 10 - 15 working days

Shortlisted for the 2018 TWS Wildlife Publication Awards in the edited book category Lesser Prairie-Chickens have experienced substantial declines in terms of population and the extent of area that they occupy. While they are an elusive species, making it difficult at times to monitor them, current evidence indicates that they have been persistently decreasing in number since the Dust Bowl of the 1930s dramatically affected their core range. In May of 2014, the United States Fish and Wildlife Service listed Lesser Prairie-Chickens as a threatened species, granting them federal protection under the Endangered Species Act, which included a special rule recognizing significant conservation planning efforts made by state and federal wildlife agencies within the geographical range of the species. Although the listing was vacated by judicial ruling in September 2015, concern for persistence of the species persists. These actions illustrate the uncertain legal status and future conservation challenges for Lesser Prairie-Chickens. Ecology and Conservation of Lesser Prairie-Chickens provides a compendium of data, analytical results, and synthesis generated among expert wildlife biologists, conservation biologists, and ornithologists. It thoroughly reviews the life history, genetics, and ecology of the species, and is ultimately directed toward developing and establishing appropriate conservation management strategies. It presents a detailed analysis of the issues and risks relative to conservation as well as an overview of potential conservation tools. It also addresses the challenges that natural resource managers continue to face in their current conservation efforts. While dealing with immediate and short-term issues in Lesser Prairie-Chicken conservation, this book is also a useful starting point for guiding future research, management, and conservation of the species. Published in collaboration with and on behalf of The American Ornithological Society, this volume in the highly-regarded Studies in Avian Biology series provides a definitive reference for researchers, managers, and policy makers as well as those with interests in environmental science, avian biology, game bird management, or Great Plains ecology.

Audubon was not the father of American ornithology. That honorific belongs to Alexander Wilson, whose encyclopedic American Ornithology established a distinctive approach that emphasized the observation of live birds. In the first full-length study to reproduce all of Wilson's unpublished drawings for the nine-volume Ornithology, Edward Burtt and William Davis illustrate Wilson's pioneering and, today, underappreciated achievement as the first ornithologist to describe the birds of the North American wilderness. Abandoning early ambitions to become a poet in the mold of his countryman Robert Burns, Wilson emigrated from Scotland to settle near Philadelphia, where the botanist William Bartram encouraged his proclivity for art and natural history. Wilson traveled 12,000 miles on foot, on horseback, in a rowboat, and by stage and ship, establishing a network of observers along the way. He wrote hundreds of accounts of indigenous birds, discovered many new species, and sketched the behavior and ecology of each species he encountered. Drawing on their expertise in both science and art, Burtt and Davis show how Wilson defied eighteenth-century conventions of biological illustration by striving for realistic depiction of birds in their native habitats. He drew them in poses meant to facilitate identification, making his work the model for modern field guides and an inspiration for Audubon, Spencer Fullerton Baird, and other naturalists who followed. On the bicentennial of his death, this beautifully illustrated volume is a fitting tribute to Alexander Wilson and his unique contributions to ornithology, ecology, and the study of animal behavior.

R4,317 Discovery Miles 43 170 Ships in 10 - 15 working days

Vocal signals are central for social communication across a wide range of vertebrate species; consequently, it is critical to understand the mechanisms underlying the learning, control, and evolution of vocal communication. Songbirds are at the forefront of research into such neural mechanisms. Indeed, songbirds provide a particularly important model system for this endeavor because of the many parallels between birdsong and human speech. Specifically, (1) songbirds are one of the few vertebrate species that, like humans, learn their vocal signals during development, (2) the processes of song learning and control in songbirds shares many parallels with the process of speech acquisition in humans, and (3) there exist deep homologies between the circuits for the learning, control, and processing of vocal signals across songbirds and humans. In addition, because of the diversity of songbirds and song learning strategies, songbirds offer a powerful model system to use the comparative method to reveal mechanisms underlying the evolution of song learning and production. Taken together, research on songbirds can not only reveal general principles underlying vertebrate vocal communication but can also provide insight into potential mechanisms underlying the learning, control, and processing of speech. This volume will cover a range of topics in birdsong spanning multiple level of analysis. Chapters will be authored by the world's leading experts on birdsong and will provide comprehensive reviews of the processes underlying song learning, of the neural circuits for song learning and control as well as for the extraction and processing of song information, of the selection pressures underlying song evolution, and of genetic and molecular mechanisms underlying the learning and evolution of song. The primary goals of this volume are to provide comprehensive, integrative, and comparative perspectives on birdsong and to underscore the importance of birdsong to biomedical research, evolutionary biology, and behavioral, systems, and computational neuroscience.The target audience of this volume will be graduate students, postdoctoral fellows, and established academics and neuroscientists who are interested in mechanisms of communication from an integrative and comparative perspective. The volume is intended to function as a high-profile and contemporary reference on current work related to the learning, control, processing, and evolution of birdsong. This volume will have broad appeal to comparative and sensory biologists, neurophysiologists, and behavioral, systems, and cognitive neuroscientists who attend meetings such as the Society for Neuroscience, the International Society for Neuroethology, and the Society for Integrative and Comparative Biology. Because of the relevance of birdsong research to understanding human speech, it is likely that the volume will also be of interest to speech researchers and clinicians researching communication, motor, and sensory processing disorders.

Bird migration is a well-researched phenological event. However, few studies in North America have investigated the effects of climate change and extreme weather on the relationships of migratory avian species and their seasonal resources. This is a critical gap in knowledge that limits our ability to prioritize management and conservation applications throughout the annual cycle. Phenological Synchrony and Bird Migration: Changing Climate and Seasonal Resources in North America explores critical linkages between migratory birds, their seasonal resources, and shifts in climate change and weather events. Gathered from projects conducted during spring or fall migration, the book covers topics such as: Conservation and management considerations for migratory birds throughout the United States with respect to climate change The relation of climate on the wintering grounds to spring migration of short- and long-distance migratory birds The relationships of migratory birds and their seasonal resources, and the nature of these relationships in the face of climate change and extreme weather events at stopover habitats in both spring and fall migration With contributions from over 40 researchers, the book will help readers understand the effects of climate change on migratory birds and will provide a solid basis for further inquiry and research in this area.

Avian Urban Ecology (Hardcover): Diego Gil, Henrik Brumm Avian Urban Ecology (Hardcover)
Diego Gil, Henrik Brumm
R4,566 Discovery Miles 45 660 Ships in 10 - 15 working days

As natural habitat continues to be lost and the world steadily becomes more urbanized, biologists are increasingly studying the effect this has on wildlife. Birds are particularly good model systems since their life history, behaviour, and physiology are especially influenced by directly measurable environmental factors such as light and sound pollution. It is therefore relatively easy to compare urban individuals and populations with their rural counterparts. This accessible text focuses on the behavioural and physiological mechanisms which facilitate adaptation and on the evolutionary process that ensues. It discusses topics such as acoustics, reproductive cues, disease, and artificial feeding, and includes a series of case studies illustrating cutting edge research on these areas. Avian Urban Ecology is suitable for professional avian biologists and ornithologists as well as graduate students of avian ecology, evolution, and conservation. It will also be of relevance and use to a more general audience of urban ecologists and conservation biologists.

Swifts live almost entirely in the air. They eat, drink, sleep, mate and gather their nesting materials on the wing, fly thousands of miles across the world, navigating their way around storms, never lighting on tree, cliff or ground, until they return home with the summer. Sarah Gibson has written a fascinating story of discovery, exploring what is known about these mysterious birds, their ancient ancestry and how they have been regarded through history. But the swifts are in real danger: often unintentionally, we are sealing our homes against wildlife of any kind. Cracks, gaps and crevices which for thousands of years have offered nesting space in buildings, are being closed off, while new housing rarely offers entry holes for nesting birds. Loss of breeding places is considered to be a significant factor in the steep decline of these birds over the last twenty years. Thankfully, there are people in the UK and across Europe striving to ensure a future for swifts. Their actions and stories are woven into the narrative, demonstrating how change is brought about by passionate, determined individuals, whose actions show that everyone can do something to keep these superb birds screaming through our skies.

The Corncrake - An Ecology of an Enigma (Paperback): Frank Rennie The Corncrake - An Ecology of an Enigma (Paperback)
Frank Rennie
R545 Discovery Miles 5 450 Ships in 9 - 17 working days

Changes in farmland management throughout the twentieth century, including agricultural intensification and increasing mechanisation, have resulted in the loss of habitat for many species. The Corncrake is one such species that has faced multiple challenges to its survival. Although it was once a common bird throughout northern Europe, the breeding areas of Corncrakes have been steadily reduced to a fraction of what they once were, and in many areas their continuation as a regularly breeding bird is in serious doubt. In addition, the behaviour of the Corncrake, nesting under the cover of tall grass and undertaking annual long-distance migrations, means that for most of the last hundred years, its detailed ecology has remained mysterious and little understood. Although there have been millions of words written about the Corncrake in scientific papers, until now there has been no full-length book that attempts to capture all the aspects of its ecology, and to present this information to non-specialists. As a result, until very recently, many important facts about its lifestyle and behaviour have not been widely known, even among ornithologists. Although scarcely seen in its natural habitat, the Corncrake is well-known in many rural areas due to its characteristic (and persistent) night-time calling, but new discoveries with the aid of acoustic science have proved surprising, and may offer new ways of improving the location, identification, and management options to protect and enable the population of this iconic species to recover, even to thrive in our countryside. A new appreciation of the requirements of this species and the ways in which our sensitive management of the whole landscape, both in its potential breeding areas across Europe and Asia and in the seasonal quarters in regions of Africa, offer new hope for the future of this fascinating bird.

Interspecific Competition in Birds (Paperback): Andre A. Dhondt Interspecific Competition in Birds (Paperback)
Andre A. Dhondt
R2,164 Discovery Miles 21 640 Ships in 10 - 15 working days

In nature there exist three main types of biotic interactions between individuals of different species: competition, predation, and mutualism. All three exert powerful selection pressures, and all three shape communities. However, the question of how important interspecific competition in nature really is remains controversial and unresolved. This book provides a critical and exhaustive review of the topic. Although the examples are limited mostly to birds (interspecific competition and community structure have been exhaustively studied in this animal group, and a lot of experimental data are available), the conclusions reached have a far broader relevance to population ecologists in general. The book reasons that the coexistence of species is the result of both past and presently on-going interspecific competition. Furthermore, understanding the importance of interspecific competition in natural systems will be increasingly important when modelling the effects of climate change on populations.

Birds have colonized almost every terrestrial habitat on the planet - from the poles to the tropics, and from deserts to high mountain tops. Ecological and Environmental Physiology of Birds focuses on our current understanding of the unique physiological characteristics of birds that are of particular interest to ornithologists, but also have a wider biological relevance. An introductory chapter covers the basic avian body plan and their still-enigmatic evolutionary history. The focus then shifts to a consideration of the essential components of that most fundamental of avian attributes: the ability to fly. The emphasis here is on feather evolution and development, flight energetics and aerodynamics, migration, and as a counterpoint, the curious secondary evolution of flightlessness that has occurred in several lineages. This sets the stage for subsequent chapters, which present specific physiological topics within a strongly ecological and environmental framework. These include gas exchange, thermal and osmotic balance, 'classical' life history parameters (male and female reproductive costs, parental care and investment in offspring, and fecundity versus longevity tradeoffs), feeding and digestive physiology, adaptations to challenging environments (high altitude, deserts, marine habitats, cold), and neural specializations (notably those important in foraging, long-distance navigation, and song production). Throughout the book classical studies are integrated with the latest research findings. Numerous important and intriguing questions await further work, and the book concludes with a discussion of methods (emphasizing cutting-edge technology), approaches, and future research directions.

Biological invaders represent one of the primary threats to the maintenance of global biodiversity, human health, and the success of human economic enterprises. The continuing globalization of our society ensures that the need to understand the process of biological invasion will only increase in the future. There is also a growing recognition that the study of biological invaders provides a unique insight into basic questions in ecology and evolution.
The study of exotic birds has had a particularly long history and has come to represent a fascinating intersection between the study of biological invasions, avian conservation biology, and basic principles of ecology and evolution. Avian Invasions summarizes and synthesizes this unique historical record and unravels the insights that the study of exotic birds brings to all three of these research strands. It includes chapters on the well-known contributions of exotic bird study to ecological science, and on the post-establishment evolution of introduced bird populations. The result is the most comprehensive picture yet of the invasion process.
Avian Invasions is aimed at professional avian biologists and ornithologists as well as graduate students of avian ecology, evolution and conservation. It also appeals to a more general audience of invasion ecologists.

The Mute Swan is not so much a bird, as a national treasure: the avian equivalent of Sir David Attenborough or the Queen. These huge and stately creatures are part of our urban and rural landscapes, a constant presence on lakes, rivers and ponds throughout Britain. Yet despite their familiarity, they are often misunderstood; and while many people love swans, others fear them. Swans also feature in myths and legends, art and literature, dance and music, not just in Britain but all around the world. Stephen Moss delves into the facts and fiction about these charismatic birds, describes their seasonal life cycle and examines their central role in our history and culture. He also includes stories about 'wild swans' - Whooper and Bewicks - that visit us in winter; and the Black Swan of Australia. 'A superb naturalist and writer' Chris Packham 'Moss has carved out an enviable niche as a chronicler of the natural world' Daily Mail
