"Abstract: In more than 150 years of research in the waters surrounding the Azores, several publications on the fauna of echinoderms of the archipelago have been produced, in the form of papers, notes, reports, reviews, and monographs. This work attempts to summarize the present knowledge on this marine group in the Azorean exclusive economic zone (i.e., waters within 200 nautical miles of the archipelago's shores). A short review of the history of the species' taxonomy is given, with key references, geographical distribution, ecology, additional notes and, when possible, figures. We herein report 172 species of echinoderms (6 crinoids, 55 ophiuroids, 45 asteroids, 36 holothurians, and 30 echinoids) from the Azores Archipelago, most of them inhabiting deep waters (>200 m). Only 29 shallow-water species were recorded locally (≤50 m depth). In general, the echinoderm species present in the Azores are characterized by a wide geographical distribution in the Atlantic Ocean. Only nine taxa (all deep-water species, >840 m) appear to be restricted to the Azorean waters. Overall, the knowledge of the echinoderm fauna of the Azores is out-dated, with many species last collected in the archipelago over 100 years ago. A recent interest in the Azorean Mid-Atlantic waters has brought oceanographic cruises back to the archipelago, thus providing new opportunities for the renewal of 150 years of echinoderm studies in the area.

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.

This bilingual publication results from a four-day symposium aimed at capturing the general directions and analytical issues that characterize approaches to sustainable use in Africa. The papers included in this work are organized under four major headings: modes of use, devolution, scale issues and external issues. Authors explore these themes through the use of case studies and the description of specific regional experiences. External issues are further explored in a series of commissioned policy papers which have also been included.

Can we unlock resilience to climate stress by better understanding linkages between the environment and biological systems? Agroclimatology allows us to explore how different processes determine plant response to climate and how climate drives the distribution of crops and their productivity. Editors Jerry L. Hatfield, Mannava V.K. Sivakumar, and John H. Prueger have taken a comprehensive view of agroclimatology to assist and challenge researchers in this important area of study. Major themes include: principles of energy exchange and climatology, understanding climate change and agriculture, linkages of specific biological systems to climatology, the context of pests and diseases, methods of agroclimatology, and the application of agroclimatic principles to problem-solving in agriculture.

Conflicts between foreign investment law and environmental law are becoming increasingly frequent. On the one hand, the rise of environmental regulation poses significant challenges to foreign investors in several industries. On the other, the surge in investment arbitration proceedings is making States aware of the important litigation risks that may result from the adoption of environmental regulation. This study of the relationship between these two areas of law adopts both a policy and a practical perspective. It identifies the major challenges facing States, foreign investors and their legal advisers as a result of the potential friction between investment law and environmental law and provides a detailed analysis of all the major legal issues on the basis of a comprehensive study of the jurisprudence from investment tribunals, human rights courts and bodies, the ICJ, the WTO, the ITLOS, the CJEU and other adjudication mechanisms.

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.

This new reexamined and corrected fauna displays an up to date account of knowledge on the systematics of the fresh and brackish water fishes of West Africa. Its aim is to help ichthyologists with the identification of the species they collect. It is made practical and didactic by paying special attention to iconography and as far as possibly by giving priority to the simplest and easiest observable criteria. West Africa, from the Senegal River basin in the North West to the Chad basin in the North East and the Cross River in the South, includes the majority of the Sahelo-Sudan basins, except for the Nile, and the Western Guinea area, covering the Atlantic Coastal Basins from Guinea to Western Cote d'Ivoire. Specialists of each group or family were called to write the chapters. To facilitate the access of this fauna, an English translation is provided for all text. Summary tables, comparing morphological characters and measures for the different species, complement the identification keys. Distribution maps are provided for freshwater species. At present, 64 families are described, including 192 genera and 584 valid species. A reduced paper version is presented in two volumes; the integral CD-ROM version is inserted on the back cover of the second volume.

In the forests of Madagascar, about nine-tenths of the plant and animal species are unique to the island. Their natural habitats range from true rainforest to the lunar landscape of the spiny desert, and the natural rock-gardens of the mountain tops. Madagascar is no oceanic island, but a fragment of continent a thousand miles long, wrenched loose from the side of Africa. In this Lost World, plants and animals have become a living museum of evolution. Aepornis, the largest bird which ever lived, became extinct on Madagascar in the last few hundred years. Many more Malagasy species are now following Aerpornis into extinction. This volume introduces Madagascar's unique fauna and flora to general readers - the first such handbook available in English, and the first book to combine articles by Malagasy, French, English and American scientists, writing in their own fields of expertise.
