Biogeographic Patterns Of South American Anurans

This book analyzes different facets of anuran amphibian distribution in South America. We integrate alternative biological metrics employing cutting-edge methods to understand the dynamic processes underlying species distribution patterns. By using the modern biogeographic toolbox, we explore how richness gradients, phylogenetic diversity, functional diversity, and range size/endemism distribution of amphibians vary along the continent. Moreover, we present a robust proposal for priority areas for conservation of anurans in South America that maximizes representativeness of distinct biodiversity facets.

Natural Molecules in Neuroprotection and Neurotoxicity brings together research in the area of natural compounds and their dual effects of neuroprotection and neurotoxicity when interacting with brain cells. This book is organized into four sections that address molecular mechanism underlying neuroprotection and neurotoxicity, neuroprotection mediated by natural molecules, neurotoxicity induced by natural compounds and nanotechnology-related strategies utilized in neuroprotection. Written by well-known researchers all over the world, chapters provide an in-depth analysis of numerous molecules, such as algae, plant and fungus-derived molecules, and comprehensively discuss their mechanisms of action and possible clinical applications. This book provides an essential reference for researchers and clinical scientists interested in the effects of natural compounds on the human health and disease. Covers both neuroprotective and neurotoxic outcomes resulted from the exposure of brain cells to natural molecules Analyzes numerous natural compounds, including animal, vegetal, fungal, bacterial, and marine-derived molecules Discusses the effects of the metabolism of microbiota on the biotransformation of natural molecules and the consequences of these processes on brain cells Contains a section focused on the nanotechnology-related strategies utilized to enhance the bioavailability of natural molecules to brain cells

The Physical Geography of South America, the eighth volume in the Oxford Regional Environments series, presents an enduring statement on the physical and biogeographic conditions of this remarkable continent and their relationships to human activity. It fills a void in recent environmental literature by assembling a team of specialists from within and beyond South America in order to provide an integrated, cross-disciplinary body of knowledge about this mostly tropical continent, together with its high mountains and temperate southern cone. The authors systematically cover the main components of the South American environment - tectonism, climate, glaciation, natural landscape changes, rivers, vegetation, animals, and soils. The book then presents more specific treatments of regions with special attributes from the tropical forests of the Amazon basin to the Atacama Desert and Patagonian steppe, and from the Atlantic, Caribbean, and Pacific coasts to the high Andes. Additionally, the continents environments are given a human face by evaluating the roles played by people over time, from pre-European and European colonial impacts to the effects of modern agriculture and urbanization, and from interactions with El Niño events to prognoses for the future environments of the continent.

This book significantly expands the coverage of this subject given by its predecessor Biogeography and Plate Tectonics (1987). Global Biogeography traces global changes in geography and biology from the Precambrian to the Recent (with worldwide coverage in chronological order); examines the evolutionary effects of the major extinctions, and discusses contemporary biogeographic regions within the context of their historic origins. It is now apparent that the biotas of the various biogeographical regions have had, and still maintain, a dynamic relationship with one another; much more than was previously thought. This is shown to be true for all three of the earth's primary habitats; marine, terrestrial and freshwater (as is clearly demonstrated in this volume). The book is splendidly illustrated with 122 text figures, an extensive bibliography, index, together with a set of biogeographic maps illustrating continental and terrain outlines from the mid-Cambrian to the Recent. University students (both advanced undergraduate and graduate level) will find it an excellent text book. For professionals in Biogeography this is a convenient reference work.

This book provides a comprehensive overview of the patterns of biodiversity in various neotropical ecosystems, as well as a discussion on their historical biogeographies and underlying diversification processes. All chapters were written by prominent researchers in the fields of tropical biology, molecular ecology, climatology, paleoecology, and geography, producing an outstanding collection of essays, synthetic analyses, and novel investigations that describe and improve our understanding of the biodiversity of this unique region. With chapters on the Amazon and Caribbean forests, the Atlantic rainforests, the Andes, the Cerrado savannahs, the Caatinga drylands, the Chaco, and Mesoamerica – along with broad taxonomic coverage – this book summarizes a wide range of hypotheses, views, and methods concerning the processes and mechanisms of neotropical diversification. The range of perspectives presented makes the book a truly comprehensive, state-of-the-art publication on the topic, which will fascinate both scientists and general readers alike.
