Balkan Biodiversity

This is the first attempt to synthesize current understanding of biodiversity in the great European hot spot. A diverse group of international researchers offers perspective on biodiversity at the level of the gene, species and ecosystem, including contributions on temporal change. Biological groups include plants, mammals, spiders and humans, cave-dwelling organisms, fish, aquatic invertebrates and algae.

The small water bodies such as headwater streams, springs, ditches, small lakes, and ponds are critical to maintaining freshwater biodiversity. This is especially true for Dinaric karst, where they are often the only water bodies present. However, despite their importance, they remain widely overlooked and excluded from government policies like the EU Water Framework Directive. This book includes information on different aspects of these essential but still neglected habitats. This book intends to be of interest to a wide range of audiences, from researchers and conservationists to the public and decision-makers.

This volume addresses recent and ongoing ethnobotanical studies in the Balkans. The book focuses on elaborating the relevance of such studies for future initiatives in this region, both in terms of sustainable and peaceful (trans-regional, trans-cultural) rural development. A multi-disciplinary viewpoint is utilized, with an incorporation of historical, ethnographic, linguistic, biological, nutritional and medical perspectives. The book is also authored by recognized scholars, who in the last decade have extensively researched the Balkan traditional knowledge systems as they pertain to perceptions of the natural world and especially plants. Ethnobotany and Biocultural Diversities in the Balkans is the first ethnobotany book on one of the most biologically and culturally diverse regions of the world and is a valuable resource for both scholars and students interested in the field of ethnobotany.

Environmental protection is one of the areas where the Balkan countries still face a big challenge to catch up with their western neighbors. After the 1990s conflicts and the breakup of Yugoslavia, six new Balkan states emerged. Apart from integrating environmental concerns into the new policies, a major challenge is environmental management across new borders. What used to be six international river basins in the Balkans have now evolved into 13 internationally shared river basins and four transboundary lake basins. The situation is similar for areas of high ecological value, many of which are often located in mountainous border areas. To ensure effective protection, entire ecosystems have to be addressed regardless of the political borders that are dividing them on a map. Transboundary cooperation between countries sharing one or more natural resources is therefore indispensable for creating common frameworks that promote their sustainable use while offering an opportunity for confidence-building between cooperating countries.

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.

From single-celled organisms in Black Sea sand to endemic cave crustaceans, from mountain glacial relict insects to the most diverse bird fauna in Europe, the fauna of Bulgaria has been a subject of study for more than a century. This is the first English language survey of all vertebrate and many key invertebrate groups of Bulgaria, their faunistics, origin, geographical and ecological distribution, and conservation issues.
