Book Description
This book presents the state of art in the field of microbial zoonoses and sapronoses. It could be used as a textbook or manual in microbiology and medical zoology for students of human and veterinary medicine, including Ph.D. students, and for biomedicine scientists and medical practitioners and specialists as well. Surprisingly, severe zoonoses and sapronoses still appear that are either entirely new (e.g., SARS), newly recognized (Lyme borreliosis), resurging (West Nile fever in Europe), increasing in incidence (campylobacterosis), spatially expanding (West Nile fever in the Americas), with a changing range of hosts and/or vectors, with changing clinical manifestations or acquiring antibiotic resistance. The collective term for those diseases is (re)emerging infections, and most of them represent zoonoses and sapronoses (the rest are anthroponoses). The number of known zoonotic and sapronotic pathogens of humans is continually growing − over 800 today. In the introductory part, short characteristics are given of infectious and epidemic process, including the role of environmental factors, possibilities of their epidemiological surveillance, and control. Much emphasis is laid on ecological aspects of these diseases (haematophagous vectors and their life history; vertebrate hosts of zoonoses; habitats of the agents and their geographic distribution; natural focality of diseases). Particular zoonoses and sapronoses are then characterized in the following brief paragraphs: source of human infection; animal disease; transmission mode; human disease; epidemiology; diagnostics; therapy; geographic distribution.

Book Description
A large number of comprehensive publications has been devoted to the Antarctic, to its plant and animal life. It is therefore relatively easy to familiarize oneself with the current state of Antarctic research. Nothing comparable is available for the Arctic. The heterogeneity and richness of the northern polar regions seem to have discouraged any attempt at a synthethic approach. This book has evolved from an attempt to summarize the results of 15 years of ecological and physiological research work in the Arctic - mostly on Spitsbergen. The necessity of comparing our results and the ecological conditions of Spitsbergen with other arctic regions grew into a full-sized book on arctic animal ecology. It is not meant as an exhaustive survey ofthe relevant literature. Instead I have tried to show how closely the various fields of research are interwoven, how many questions can be solved if only notice is taken of fellow scientists and their results, and how much arctic animals have in common. This book would not have been possible without the helpfulness of many colleagues. Above all I should like to mention Professor Ronning and Professor Solem of Trondheim University (Norway), Professor Arnthor Gardasson of Reykjavik University (Iceland), Dr. NettIeship, Dr. Oliver and Dr. Ryder of Canada and Professor West of Fairbanks University (Alaska, USA).

Book Description
Peter Stiling, co-author of Biology by Brooker et al., has introduced a new ecology text to the market. The main goal of this latest ecology text is to show how ecology is important in understanding global change. The book's main objective is to teach the basic principles of ecology and to relate these principles to many of the Earth's ecological problems. Users who purchase Connect Plus receive access to the full online ebook version of the textbook.

Book Description
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.

Book Description
Most protected areas (e.g.national parks and nature reserves) have been created to protect wildlife and land- and seascape values. They currently cover over 13% of the world's land surface, around 12% of marine coastal areas and 4% of the marine shelf. Retaining and expanding these areas in the future will depend on showing their wider benefits for society. This book provides a concise and persuasive overview of the values of protected areas. Contributing authors from over fifty countries examine a wide range of values that are maintained in protected areas, including food, water and materials; health; tourism; cultural and spiritual values; and buffering capacity against climate change and natural disasters. The book also considers the role of protected areas in poverty reduction strategies, their relationship with traditional and indigenous people and in fostering conflict resolution through peace parks initiatives. The chapters draw on a series of authoritative reports published by WWF over recent years under the 'Arguments for Protection' banner, in association with various partners, and on additional research carried out especially for the volume. It analyses the opportunities and limitations of protected areas for supplying the various values along with practical advice for planners and managers about maximising benefits. It provides an important contribution to the debate about the role of protected areas in conservation and other aspects of natural resource management and human livelihoods. Published with WWF

Book Description
Owls in Australia are difficult to find and study, so comparatively little is known about their biology. Even less is known about the status, taxonomy, and biology of those species and sub-species living in tropical and subtropical environments and on islands. Many island species and subspecies are at risk, some have already been lost. Ecology and Conservation of Owls includes sections on population ecology, distribution, habitat and diet, conservation and management, and voice structure and taxonomy. It contains a number of review chapters that bring together findings from a wide range of previous research, including recent developments in owl taxonomy and systematics, and studies of population limitation in northern hemisphere owls. The chapters in this book derive from papers presented at the Owls 2000 conference held in Canberra, Australia, which was third in a series of international meetings on owls.
