Book Synopsis In Search of Arctic Birds by : Richard Vaughan
Download or read book In Search of Arctic Birds written by Richard Vaughan and published by A&C Black. This book was released on 2010-10-30 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arctic birds have long held a fascination for Richard Vaughan, whose trips to the region, watching and photographing birds, have provided the raw material for a number of previous publications. Here, he focuses on the historical aspects of Arctic ornithology, bringing to life not only the birds but the activities of those who have lived with them, or explored in search of them. A general introduction to the Arctic and the forces that shape its bird populations and their biology is followed by sections on native peoples, whaling and discovery ships, and the famous ornithologists who have investigated these often inhospitable habitats. Conservation, both of individual species and of habitats, is discussed against the background of threats to the Arctic environment. Since half the Arctic lies in Russia, detailed consideration is naturally given to Arctic bird studies in that country, as well as in North America and Greenland. Purely ornithological interludes look in detail at the Gyrfalcon, Knots, Ross's Gull, geese, divers, Snowy Owls and many more. The book includes practical advice on how to visit the Arctic and where and when to go. Richard Vaughan's own photographs and the drawings of Swedish artist Gunnar Brusewitz do real justice to the beauty of both the environment and its birds.
Book Synopsis Arctic and Alpine Environments by : Jack D. Ives
Download or read book Arctic and Alpine Environments written by Jack D. Ives and published by Routledge. This book was released on 2019-10-08 with total page 1202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1974, Arctic and Alpine Environments examines, the relatively simple ecosystems of arctic and alpine lands that still occupy extensive areas little disturbed by modern technology. The book argues that there is a necessity for carefully controlled development of the resources of these regions and suggests that there is a risk of irreversible disturbance without full understanding of these regions. This book provides a detailed documentation of cold-stressed arctic and alpine terrestrial environments and systematically deals with the present and past physical environment – climate, hydrology and glaciology; biota – treeline, vegetation, vertebrate zoology, and historical biogeography; abiotic processes – geomorphological and pedological and the role of man – bioclimatology, archaeology and technological impact, including radioecology. The book will appeal to academics and students of environmental and biological science, as well as providing a significant source for conservationists’, government agencies and industrial organizations.

Download or read book Avian Biology written by Donald S. Farner and published by Academic Press. This book was released on 2013-09-17 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: Avian Biology, Volume V is a collection of papers that deals with the biology of birds concerning their mechanics of flight and migration. The first paper describes the mechanics of bird flights such as gliding, soaring, and the energy requirements of this activity. Other papers investigate the control and metabolic physiology of migration, including flight restlessness and fat metabolism. Other topics cover migratory orientation research involving topographical, meteorological, inertial, magnetic, and celestial cues. Upon migration to different environments, birds have to adapt as their circadian and circannual rhythms are affected. One paper discusses the works of Wynne-Edwards, Aschoff and Wever, and Leopold and Eynon regarding their observations of bird migration cues. One author describes the vocal behavior in birds, including the dual sound theory where two sound sources can occur in each bronchus. Of interest to many in this paper is the description of the different stages in song development. Other papers discuss the incubation behavior of birds as well as the energetics involved. This book is suitable for zoologists, bird enthusiasts, and avian biologists.
Download or read book The Common Eider written by Chris Waltho and published by Bloomsbury Publishing. This book was released on 2015-01-15 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: A monograph of the Common Eider, a large and familiar duck with a long and fascinating cultural history. A common sight around the more northerly shores of the British Isles, the Common Eider is the largest duck in the northern hemisphere. The eider is particularly well adapted to cold-water environments; the insulating properties of eider down are iconic. The species is taxonomically interesting, with a range of well-marked subspecies reflecting the patterns of ice coverage during ancient glaciations, and these ducks have also provided the focus for a number of important behavioural studies, especially on feeding ecology and energy budgets. Eiders have a long association with humans, and have deep cultural significance in many societies. However, modern lifestyles are exposing these ducks to a wide range of new pressures. This monograph provides a comprehensive portrait of the Common Eider; authors Chris Waltho and John Coulson bring together an extensive and diverse international literature, with sections on taxonomy, habitats, breeding biology, population dynamics, diet and foraging, dispersal and migration, and conservation.
Book Synopsis The North American Swans: Their Biology and Conservation by : Paul Johnsgard
Download or read book The North American Swans: Their Biology and Conservation written by Paul Johnsgard and published by Lulu.com. This book was released on 2020-03-23 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among birds, swans are relatively long-lived species and are also among the most strongly monogamous, having prolonged pair and family bonds that strongly influence their reproductive and general social behavior, which, in combination with their beauty and elegance, contribute to the overall high degree of worldwide human interest in them. This volume of more than 59,000 words describes the distributions, ecology, social behavior, and breeding biologies of the four species of swans that breed or have historically bred in North America, including the native trumpeter and tundra swans, the introduced mute swan, and the marginally occurring whooper swan. Also included are 5 distribution maps, 15 drawings, 27 photographs by the author, and a reference section of nearly 1,000 literature citations.
