The thirtieth volume of Geographers: Biobibliographical Studies adds significantly to the corpus of scholarship on geography's multiple histories and biographies with nine essays on figures from Britain, France, the USA and Spain. Each was distinguished in his or her own scholarship and made distinctive contributions in specific fields -- as historical, political or population geographers, and, in one case, as a hydrologist-geomorphologist. The subjects also shared a commitment to the educational benefits of geography and of geographical research that was rooted in a vision of geography as socially illuminating and individually life-changing. Here is further rich testimony of the importance of geographers' lives to the lived experience of geography in practice.
Groundwater resources naturally contain high levels of arsenic in many parts of the world. Over the last two decades, the As-containing groundwater in South-East Asia has received much attention, but the situation is just as crucial in Latin America, where the number of studies is still relatively low, and the extent and severity of As-exposure in the populations has yet to be fully evaluated. This book aims to promote knowledge of the occurrence and genesis of As-rich groundwater in Latin America. It deals with constraints on the mobility of As in groundwater, As-uptake from soil and water by plants, As-propagation through the food chain, human health impacts, and As-removal technologies. Case studies are presented from Argentina, Bolivia, Chile, Ecuador, El Salvador, Mexico, Nicaragua and Peru, amongst others, and are viewed against the background of experience from other world regions. The book is a state-of-art overview of arsenic research in Latin America. It aims to create interest within the Latin American countries affected by the presence of arseniferous aquifers and to increase awareness among administrators, policy makers and company executives. It will also serve to inform the international scientific community, and improve international cooperation on arsenic in groundwater.

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
