In August of 2005, scientists conducted a rapid inventory in Sierra del Divisor, a mountain range that rises up dramatically from the lowlands of central Amazonian Peru. This assessment, presented here in English and Spanish, collects their research on the plants and animals of the region as well as the social and cultural assets of local villages and their use and management of natural resources. The report includes recommendations for conservation and management, including steps to safeguard the voluntarily isolated indigenous people living in the region. Corine Vriesendorp is a...

La obra trata de los fundamentos de Química Orgánica necesarios para poder seguir estudios de química, ingeniería química, farmacia y biología. Como en la mayor parte de libros introductorios, por cuestiones pedagógicas se presenta la química orgánica por grupos funcionales. Concebida para que se entienda la reactividad y las causas que originan los cambios químicos y no para dar un conocimiento enciclopédico de las reacciones, la obra pretende dejar claros una serie de principios fundamentales a partir de los cuales el alumno pueda abordar situaciones más complejas. Otras...

In previous volumes in this series, Advances in Metal and Semiconductor Clusters, the focus has been on atomic clusters of metals, semiconductors and carbon. Fundamental gas phase studies have been surveyed, and most recently scientists have explored new materials which can be produced from clusters or cluster precursors. In this latest volume, the focus shifts to clusters composed primarily of non-metal molecules or atoms which have one or more metal atoms seeded into the cluster as an impurity. These clusters provide model systems for metal ion solvation processes and metal-ligand...

Charles Darwin spent the majority of his 1832-1833 voyage around the world in southern South America, and his early experiences in the Cape Horn region may have triggered his first ideas on human evolution. Darwin was not only a field naturalist, but also a scholar of the observations of the European explorers who preceded him. This book illuminates the foundations of Cape Horn’s natural history records as they oriented Darwin’s own explorations and his ideas on natural selection. Richly illustrated with maps and color photographs, this book also offers a guide to the sites visited by...
