A comprehensive monograph of the beautiful Snowy Owl, famed for its elegant, all-white plumage. The Snowy Owl needs little introduction. This massive white owl breeds throughout the Arctic, wherever there are voles or lemmings to hunt, from Scandinavia through northern Russia to Canada and Greenland. Southerly movements in winter see North American birds travel as far south as the northern United States, while infrequent vagrants on the Shetlands and other northern isles are a magnet for birders. The Snowy Owl gives this popular bird the full Poyser treatment, with sections on morphology, distribution, palaeontology and evolution, habitat, breeding, diet, population dynamics, movements, interspecific relationships and conservation, supported by some fabulous photography. The award-winning author team also had access to Russian research literature, which is generally out of reach for Western scientists.

The purpose of this report is "to summarize ... the information required to assess the state of the Arctic's natural environment today ... ; to provide a useful reference to a wide audience of policy makers, Arctic residents, researchers, and others active in the conservation of Arctic flora and fauna; to point the way to improving our collective understanding and facilitating the international cooperative action required to conserve the Arctic's natural environment."--Page 11.
Temperature and other climate variables are currently changing at a dramatic rate. As observations have shown, these climatic changes have serious consequences for all organisms and their ability to adapt to changing environmental conditions. Birds are excellent model organisms, with a very active metabolism, they are highly sensitive to environmental changes and as highly mobile creatures they are also extremely reactive. Birds and Climate Change discusses our current knowledge of observed changes and provides guidelines for studies in the years to come so we can document and understand how patterns of changing weather conditions may affect birds. - Provides reviews of long-term datasets - Incorporates meta-analyses of studies about climate change effects on birds - Includes guidelines and suggestions for further studies
An updated edition of the only book dedicated to the terrestrial ecology of the East Asian tropics, authored by a world-renowned tropical ecologist
The Migration Ecology of Birds, Second Edition covers all aspects of this absorbing subject, including migratory processes, problems of navigation and vagrancy, timing and physiological control of migration, large-scale movement patterns, the effects of recent climate change, the problems that migrants face, and the factors that limit their populations. This book provides a thorough and in-depth review of the state of the science, with the text supplemented by abundant tables, maps and diagrams. Written by a world-renowned avian ecology and migration researcher, this book reveals the extraordinary adaptability of birds to the variable and changing conditions across the globe. This book represents the most updated and detailed review of bird migration, its evolution, ecology and bird physiology. Written in a clear and readable style, it will appeal not only to migration researchers in the field and ornithologists, but to anyone with an interest in this fascinating subject. - Features updated and trending ecological aspects, including various types of bird movements, dispersal and nomadism, and how they relate to food supplies and other external conditions - Contains numerous tables, maps, diagrams, a glossary, and a bibliography of more than 3,000 up-to-date references - Written by an active researcher with a distinguished career in avian ecology, including migration research
The field of marine mammal science has made enormous strides in the last ten years as well as attracting a large amount of interest, due no doubt to the public appeal of whales, dolphins, and seals, which are never out of media attention. The purpose of this book is to review key topics through chapters on the major disciplines from invited authorities around the world. Subjects covered include evolution and genetics, life histories, ecology, physiology, behaviour, medicine (diseases, parasitology), survey methodology, and all the main conservation issues (pollution, fisheries interactions, and sound disturbance). The book has an ecological and conservation emphasis since these are subject areas calling for the most attention in the modern world, but other areas such as evolution, physiology, and medicine are also given in-depth treatment. The book is written at the level of the undergraduate or above, although its style should appeal to anyone with a serious interest in marine mammal science.
Bushmeat has always provided a source of nutrition and traditional medicine for local people throughout Asia; this important resource is becoming increasingly under pressure due to loss of forest and overharvesting because of rising demand from growing human populations and trade (legal and illegal). For this reason, the conservation of forests and sustainable use of wildlife are both imperative for improving rural livelihoods and poverty alleviation. A comprehensive literature review yielded 236 papers relevant to this topic, with the greatest number of papers discussing Southeast Asia (61%) followed by South Asia (22%) and East Asia (16%). Potential solutions that emerged from the review include the use of: measures of harvest to better gauge sustainable offtake levels, protected areas and recovery zones; improved governance; and the implementation of co-management partnerships. Potential solutions for the traditional medicine trade include urban demand reduction campaigns, introduction of synthetic alternatives, increased efforts to reduce illegal trade, and implementation of certification schemes for wildlife products. In all of these cases, a myriad of social implications, such as the importance and spiritual significance of bushmeat in different cultures, the preferences for bushmeat over farmed alternatives and the tradition of wildlife-derived medicines, must be considered. Areas for further research include: the study of climate change on bushmeat and food security; the traditional medicine supply chain; consumer reaction to synthetic alternatives; the use of bushmeat particularly for medicinal purposes in urban societies; and the negative effects of the growing wildlife trade on local livelihoods.
