The United Nations Conference on the Environment and Development (UNCED), held in Rio de Janeiro in 1992, spawned a multitude of pro grammes aimed at assessing, managing and conserving the earth's biological diversity. One important issue addressed at the conference was the mountain environment. A specific feature of high mountains is the so-called alpine zone, i. e. the treeless regions at the uppermost reaches. Though covering only a very small proportion of the land surface, the alpine zone contains a rela tively large number of plants, animals, fungi and microbes which are specifi cally adapted to cold environments. This zone contributes fundamentally to the planet's biodiversity and provides many resources for mountain dwelling as well as lowland people. However, rapid and largely man-made changes are affecting mountain ecosystems, such as soil erosion, losses of habitat and genetic diversity, and climate change, all of which have to be addressed. As stated in the European Community Biodiversity Strategy, "the global scale of biodiversity reduction or losses and the interdependence of different species and ecosystems across national borders demands concerted international action". Managing biodiversity in a rational and sustainable way needs basic knowledge on its qualitative and quantitative aspects at local, regional and global scales. This is particularly true for mountains, which are distributed throughout the world and are indeed hot spots of biodiversity in absolute terms as well as relative to the surrounding lowlands.

Originally published in 2002, Mountain Biodiversity deals with the biological richness, function and change of mountain environments. The book was birthed from the first global conference on mountain biodiversity and was a contribution to the International Year of Mountains in 2002. The book examines biological diversity as essential for the integrity of mountain ecosystems and argues that this dependency is likely to increase as environmental climates and social conditions change. This book seeks to examine the biological riches of all major mountain ranges, from around the world and using existing knowledge on mountain biodiversity, examines a broad range of research in diversity, including that of plants, animals, human and bacterial diversity. The book also examines climate change and mountain biodiversity as well as land use and conservation.

Part of the worldwide biodiversity program DIVERSITAS, the Global Mountain Biodiversity Assessment (GMBA) assesses the biological richness of high-elevation biota. GMBA's focus includes the uppermost forest regions or their substitute rangeland vegetation, the treeline ecotone, and the alpine and nival belts. Providing more than description, the GM

As human populations expand and have increasing access to technol ogy, two general environmental concerns have arisen. First, human pop ulations are having increasing impact on the earth system, such that we are altering the biospheric carbon pools, basic processes of elemental cycling and the climate system of the earth. Because of time lags and feedbacks, these processes are not easily reversed. These alterations are occurring now more rapidly than at any time in the last several million years. Secondly, human activities are causing changes in the earth's biota that lead to species extinctions at a rate and magnitude rivaling those of past geologic extinction events. Although environmental change is potentially reversible at some time scales, the loss of species is irrevo cable. Changes in diversity at other scales are also cause for concern. Habitat fragmentation and declines in population sizes alter genetic di versity. Loss or introduction of new functional groups, such as nitro gen fixers or rodents onto islands can strongly alter ecosystem processes. Changes in landscape diversity through habitat modification and frag mentation alter the nature of processes within and among vegetation patches. Although both ecological changes altering the earth system and the loss of biotic diversity have been major sources of concern in recent years, these concerns have been largely independent, with little concern for the environmental causes the ecosystem consequences of changes in biodiversity. These two processes are clearly interrelated. Changes in ecological systems cause changes in diversity.

It is in the best interest of all concerned that tourism become sustainable and environmentally compatible. This need for "sustainable development" is and more by the responsible parties. Moreover, in the being recognised more search for solution strategies the realisation is gaining ground that tourism must be viewed as a worldwide phenomenon whose development must be co-ordinated in a co-operative effort spanning regions and continents. That the preservation of biological diversity also requires global co operation has been confirmed by over 170 countries which have already acceded to the "Convention on Biological Diversity". It is thus an important task to provide the foundations for joint action. Germany, one of the largest source countries of international tourism, must feel particularly obligated in this regard. The report published here is the result of a research project com missioned by the German Federal Agency for Nature Conservation. The study pursued and examined the thesis that the Convention on Biological Diversity be used as a central instrument for arriving at international principles and regulations for combining nature conservation and tourism which could lead to a sustainable development of tourism. To further the discussion, the authors brought the study to a logical conclusion by working out a proposal for a "tourism protocol" additional to the existing Convention on Biodiversity. Such a protocol additional to the Convention would entail the stipulation of internationally binding implementation and regulations for achieving sustainable tourism.

This present volume focuses on biogeographic dimensions, biodiversity conservation, and sustainable use of its components in socio-economic development. A holistic perspective of biodiversity conservation includes biogeo monitoring and indicators, climate change, tourism, and invasive and alien species. Special attention has been given on mountain, coastal, and marine biodiversity, as well as ecodevelopment in protected areas, local knowledge, technology transfer, education, and public awareness. Biogeography and Biodiversity contains 26 chapters relating to conceptual and empirical case studies from developed and developing countries. The book also combines science and policy perspectives to biogeography and biodiversity. It will be of interest to students, researchers, and teachers in geography, environmental studies, biosciences, ecology, and policy science.

Reviewed here is the current state of knowledge concerning the relationship between global change and biodiversity of temperate ecosystems. The aim is to improve the ability to conserve biodiversity under conditions of global change. The book focuses on: - The threats posed by global change to biodiversity in temperate ecosystems; - Levels and spatial patterns of diversity in temperate ecosystems; - The impact of global change on genetic diversity; - The effects of disturbance (natural and anthropogenic) on temperate ecosystems; - Existing research priorities and programmes.

Tourism is a way to use global biodiversity, and it may have impacts on it. As tourism activities concentrate on coastal areas, the purpose of the present study is twofold: first, to analyse where and to what extent conflicts exist, or may be expected to arise, between conservation of biological diversity and development of tourism; secondly, to work out approaches and concepts which may be used to avoid and settle such conflicts. The global level is considered first; a discussion of the European context and case studies from various regions follow. The last part of the study concerns aspects of international law with regard to sustainable tourism.
