Reviews of United Kingdom Statistical Sources are comprehensive and authoritative surveys of the economic and social statistics for the United Kingdom. They are indispensable to anyone who needs to gain a thorough understanding of the sources for the study of the area under consideration. This volume is concerned with the key area of investment in research and development activity. It considers the approaches adopted to the measurement of the level and nature of R&D. The real levels of commitment to R&D form strategic information for business enterprise and governments who are increasingly concerned about quality competition. In particular it reviews expenditure and manpowere measures of R&D activity. The detailed listings are preceded by definitions of R&D related to the sciope and limitations of the data collected. All those working on technological change and industrial economics will need this book.

Here is the first systematic handbook treatment of quantitative modeling natural resource problems, their allocated efficient use, and societal and economic impact. Andrés Weintraub is the very top person in Natural Resource research. He has selected co-editors who are at the top of the sub-fields in natural resources: agriculture, fisheries, forestry, and mining. The book covers these areas with contributions from researchers on, among others, modeling natural research problems, quantifying data, and developing algorithms.

Atlantic Salmon is a cultural icon throughout its North Atlantic range; it is the focus of probably the World’s highest profile recreational fishery and is the basis for one of the World’s largest aquaculture industries. Despite this, many wild stocks of salmon are in decline and underpinning this is a dearth of information on the nature and extent of population structuring and adaptive population differentiation, and its implications for species conservation. This important new book will go a long way to rectify this situation by providing a thorough review of the genetics of Atlantic salmon. Sponsored by the European Union and the Atlantic Salmon Trust, this book comprises the work of an international team of scientists, carefully integrated and edited to provide a landmark book of vital interest to all those working with Atlantic salmon.

Explore the multiple issues that surround species declines and conservation efforts through the only reference source to examine the conflicting conservation issues of 49 endangered species. While the causes of endangerment are relatively easy to understand, the ultimate or underlying factors are often far more complex and difficult to address. An introduction to these issues and how to resolve them is provided in this unique collection of case studies of animal species that have been pushed to the brink of extinction. Each case study provides the following information: - Common name - Scientific name - Order - Family - Status - Threats - Habitat - Distribution - Natural history - Conflicting Issues - Future and Prognosis. Conservationists are increasingly recognizing that the ultimate causes of extinction are primarily socio-economic and political, yet biological approaches to recovery continue to dominate. More inclusive, interdisciplinary conservation programs are explored here to offer better prospects for managing problems and conflicts. In addition to the case studies, trends and common themes are explored to provide a comprehensive, interdisciplinary approach to conservation. Students and teachers can explore a wide variety of endangered species programs and the conflicting issues common to recovery efforts, which will enable them to evaluate conservation practice and to draw their own conclusions for improvement.

The Cairngorms area is arguably the most significant for nature conservation in the British Isles and contains its largest National Park. In this book, 35 authors, drawing on published and unpublished sources, present an up-to-date review of the area's natural features, including plants, animals, habitats, geology and landforms. The review falls into three parts. The first and largest part describes the area's rich diversity of nature, with each chapter summarising recent research findings, trends and conservation issues for a different landform, habitat or species group. The second part considers deer management, recreation and projected climate change impacts. Part three focuses on rare and threatened species, and identifies areas and habitats rich in species for which the Cairngorms are nationally and internationally important.
