El departamento del Guaviare es una zona de confluencia de elementos de la Amazonía, Orinoquía y escudo guayanés, condición que se refleja en la diversidad de anfibios y reptiles. Esta obra, que incluye algunas de las especies de este grupo faunístico registradas en el municipio de San José del Guaviare, nace del interés de la Universidad Nacional de Colombia y de la financiación de la "Dirección Nacional de Extensión, Innovación y Propiedad Intelectual", por apoyar proyectos sociales de turismo naturaleza en la región.
In 1712, English naturalist Mark Catesby (1683–1749) crossed the Atlantic to Virginia. After a seven-year stay, he returned to England with paintings of plants and animals he had studied. They sufficiently impressed other naturalists that in 1722 several Fellows of the Royal Society sponsored his return to North America. There Catesby cataloged the flora and fauna of the Carolinas and the Bahamas by gathering seeds and specimens, compiling notes, and making watercolor sketches. Going home to England after five years, he began the twenty-year task of writing, etching, and publishing his monumental The Natural History of Carolina, Florida, and the Bahama Islands. Mark Catesby was a man of exceptional courage and determination combined with insatiable curiosity and multiple talents. Nevertheless no portrait of him is known. The international contributors to this volume review Catesby’s biography alongside the historical and scientific significance of his work. Ultimately, this lavishly illustrated volume advances knowledge of Catesby’s explorations, collections, artwork, and publications in order to reassess his importance within the pantheon of early naturalists.

The conventional approach to river protection has focused on water quality and maintaining some "minimum" flow that was thought necessary to ensure the viability of a river. In recent years, however, scientific research has underscored the idea that the ecological health of a river system depends not on a minimum amount of water at any one time but on the naturally variable quantity and timing of flows throughout the year. In Rivers for Life, leading water experts Sandra Postel and Brian Richter explain why restoring and preserving more natural river flows are key to sustaining freshwater biodiversity and healthy river systems, and describe innovative policies, scientific approaches, and management reforms for achieving those goals. Sandra Postel and Brian Richter: explain the value of healthy rivers to human and ecosystem health; describe the ecological processes that support river ecosystems and how they have been disrupted by dams, diversions, and other alterations; consider the scientific basis for determining how much water a river needs; examine new management paradigms focused on restoring flow patterns and sustaining ecological health; assess the policy options available for managing rivers and other freshwater systems; explore building blocks for better river governance. Sandra Postel and Brian Richter offer case studies of river management from the United States (the San Pedro, Green, and Missouri), Australia (the Brisbane), and South Africa (the Sabie), along with numerous examples of new and innovative policy approaches that are being implemented in those and other countries. Rivers for Life presents a global perspective on the challenges of managing water for people and nature, with a concise yet comprehensive overview of the relevant science, policy, and management issues. It presents exciting and inspirational information for anyone concerned with water policy, planning and management, river conservation, freshwater biodiversity, or related topics.

"The first approach can be called vertical since what is explored here is the human body's relationship to the divine, to the bestial and to the machines that imitate or simulate it. The second approach covers the various junctures between the body's "outside" and "inside": it can therefore be called a "psychosomatic" approach, studying the manifestation - or production - of soul and the expression of emotions through the body's attitudes, and, on another level, the speculations inspired by cenesthesia, pain and death. Finally, the third approach ... brings into play the classical opposition between organ and function by showing how a certain organ or bodily substance can be used to justify or challenge the way human society functions ..." - foreword Part 3.

The 1994 IUCN Red List of Threatened Animals was a major advance on its predecessors in clarity of layout and amount of information presented. This is taken further in the 1996 edition, which is also the first global compilation to use the complete new IUCN Red List category system.
