The Central Andean Altiplane represents a unique extreme environment due to its high altitude, closed basins that modulate the salt pans and saline wetlands surrounded by deserts, as well as the considerable influence of volcanic activity. UV radiation, arsenic content, high salinity, alkalinity and low dissolved oxygen levels, together with extreme daily temperature fluctuations and oligotrophic conditions, shape an environment that resembles the early Earth and, even more, extraterrestrial conditions. By developing simple biofilms stratified microbial mats or complex microbialites, extreme microbial ecosystems, colonize and thrived in different environments like salt flats, wetlands, lakes volcano vents, geysers and deserts. This book presents our current understanding of these amazing ecosystems, providing a basis for their protection and sustainable utilization. The main audience for this book included researchers and graduate students as well as professionals working in the government, mining industry and similar activities.

This volume discusses the challenges of Latin America in global environmental geopolitics. Written by leading experts, this book brings together Latin American research on global environmental change. They cover a range of topics such as climate change, water, forest and biodiversity conservation connected with science policies, public opinion, priorities of international funds, and international politics of Latin American countries. The book describes the discrepancy between the international priorities and the regional needs or country interests. It includes several case studies and analyses the cooperation in multilateral negotiations on climate change. It also offers a synthesis of debates around global environmental changes and Latin American politics, which the authors have previously promoted in different academic events in South America, including in Santiago de Chile in Chile, and Buenos Aires and Ushuaia in Argentina. This book assesses the environmental problems from different perspectives, highlights the scientific development in the environmental changes affecting Latin America and offers a new view on geopolitics to help face those issues. Specialist readers in international relations, political sciences, environmental sciences, geography and geopolitics will appreciate this up-to-date examination of Latin America and the global environmental change.

Life began in the sea, and even today most of the deep diversity of the planet is marine. This is often forgotten, especially in tropical countries like Costa Rica, renowned for their rain forests and the multitude of life forms found therein. Thus this book focusing on marine diversity of Costa Rica is particularly welcome. How many marine species are there in Costa Rica? The authors report a total of 6,777 species, or 3. 5% of the world’s total. Yet the vast majority of marine species have yet to be formally described. Recent estimates of the numbers of species on coral reefs range from 1–9 million, so that the true number of marine species in Costa Rica is certainly far higher. In some groups the numbers are likely to be vastly higher because to date they have been so little studied. Only one species of nematode is reported, despite the fact that it has been said that nematodes are the most diverse of all marine groups. In better studied groups such as mollusks and crustaceans, reported numbers are in the thousands, but even in these groups many species remain to be described. Indeed the task of describing marine species is daunting – if there really are about 9 million marine species and Costa Rica has 3. 5% of them, then the total number would be over 300,000. Clearly, so much remains to be done that new approaches are needed. Genetic methods have en- mous promise in this regard.

Scientific research in the service of economic and social development is supported by most governments and many kinds of organizations, but decisions about the determination of priorities and the allocation of resources are always difficult. This volume, first published in 1979, contains a comprehensive and meticulous study of the factors, human as well as material, related to scientists' effectiveness in meeting research goals. An international research team, co-ordinated by Unesco, surveyed members of more than 1,200 different research groups working in a variety of disciplines in universities, government and private research institutes and industry. Systematic samples from six European countries - Austria, Belgium, Finland, Hungary, Poland and Sweden - are represented in the data. The authors' innovative conceptual approaches and techniques will be of great interest to organizational psychologists and sociologists; their substantive findings, which challenge conventional wisdom about strategies for maximizing scientific productivity, will have important implications for all those concerned with science policy planning.

This series presents studies that have used the paradigm of landscape ecology. Other approaches, both to landscape and landscape ecology are common, but in the last decade landscape ecology has become distinct from its predecessors and its contemporaries. Landscape ecology addresses the relationships among spatial patterns, temporal patterns and ecological processes. The effect of spatial configurations on ecological processes is fundamental. When human activity is an important variable affecting those relationships, landscape ecology includes it. Spatial and temporal scales are as large as needed for comprehension of system processes and the mosaic included may be very heterogeneous. Intellec tual utility and applicability of results are valued equally. The Inter national Association for Landscape Ecology sponsors this series of studies in order to introduce and disseminate some of the new knowledge that is being produced by this exciting new environmental science. Gray Merriam Ottawa, Canada Foreword This is a book about real nature, or as close to real as we know - a nature of heterogeneous landscapes, wild and humanized, fine-grained and coarse-grained, wet and dry, hilly and flat, temperate and not so temper ate. Real nature is never uniform. At whatever spatial scale we examine nature, we encounter patchiness. If we were to look down from high above at a landscape of millions of hectares, using a zoom lens to move in and out from broad overview to detailed inspection of a square meter we would see that patterns visible at different scales overlay one another.

This book provides readers with in-depth insights into the changes in the Pantanal wetland from its formation to the actual and likely future states. It reveals that today’s Pantanal is an evolutionary consequence of geological, ecological and, more recently, man-made events taking place at distinct space-time intervals. Topics include geotectonics and sun-earth interactions, which largely dictate the rate of drastic changes that eventually disrupt ecological stability and radically rebuild the regional landscape. Furthermore, the biota-climate system is discussed as a major driver reshaping the ecohydrology functioning of the landscape on an intermediate timescale. Also covered are major changes in the landscape ecohydrology and biodiversity due to recent land-use and climate changes induced by humankind in the Anthropocene. The ability to recognize how those temporal scales impact the Pantanal wetland provides the opportunity for wise management approaches and the sustainable development of the region.
