The Amazonia is the largest continuous river basin and rainforest ecosystem in the world. In all aspects it is a natural wonder, and the rainforest with its billions of trees is a vital carbon store that slows down the advance of global warming. It is home to one million indigenous people and some three million species of plants and animals. There have been many climate fluctuations during the last 55 million years of its existence, but never before have “the lungs of the world” been at greater risk than they are today due to uncontrolled fires, expanding agriculture and heavy industrial development in the forms of oil drilling, mining and large hydroelectric dams. Over twelve chapters, this book describes the anthropological, biological and industrial problems facing the Amazonia, and seeks to find new solutions.
The loss of biological diversity has become an increased concern over recent years and is now enshrined in international conventions. Most biodiversity in fact occurs in the soil. Soil organisms (especially bacteria, fungi and soil invertebrates) play a major role in the formation of soil structure and are primary agents of decomposition and are drivers of nutrient cycling, and hence agricultural production.This book reviews soil biodiversity in one of the key biodiversity hotspots of the world, i.e. the Amazon and nearby regions of Brazil. It covers both the tropical savannah and rain forests . The work reported is based on a project "Conservation and Sustainable Management of Below-Ground Biodiversity", executed by TSBF-CIAT with co-financing from the Global Environment Facility (GEF) and implementation support from the United Nations Environment Programme (UNEP). The book represents a major contribution to the literature and will interest those in biodiversity conservation, soil scienceand ecology and biodiversity conservation.
This book provides an analysis of the recent governance of the Amazon in Brazil, Peru, Bolivia and Colombia with a particular focus on deforestation processes, demonstrating that current policies and political and socioeconomic dynamics in the four countries are risking the forest’s resilience. The authors examine and compare Amazonian politics and policies under different administrations, concentrating on the main actors, policies and dynamics that have affected the region, as well as on the institutional and political environment in which deforestation processes were embedded in different periods. Essentially, the book makes an analytical contribution towards a better understanding of the political, economic and social challenges confronting conservation policy in the Amazonian countries. Climate Change and Biodiversity Governance in the Amazon: At the Edge of Ecological Collapse? is essential reading for students and researchers in the fields of environmental studies and sustainability, Latin American studies, political science and international relations, as well as for policymakers and practitioners working in conservation and development.
Few tropical ecosystems have been subjected to multi-disciplinary investigations as broad and exhaustive as those carried out on the Ilha de Maraca, a riverine island in the Brazilian Amazon. This diverse and remarkable ecological reserve, in Brazil s northernmost Amazon state of Roraima, includes environments and habitats ranging from rainforests and semi-deciduous forests to natural savannas, lakes, rivers and palm swamps. These have been subjected to an in-depth international scientific study whose primary aim was to undertake one of the most detailed ecological surveys ever conducted in Amazonia. The results of this enormous body of research, involving the collaborative fieldwork of some 200 workers, span the reserve s geology, geomorphology, botany, zoology, phenology, soils, limnology, ecology and historical human occupation. These have been carefully drawn together in this volume in such a manner as to provide not only a coherent and scholarly picture of an unique and fascinating environment, but also an important and enduring source of reference for a broad spectrum of disciplines to the Amazon environment. This book is a timely reminder of the crucial importance of our understanding of rainforest components and their interrelationships, appearing as it does at a period when there is an intense interest in this extremely endangered ecosystem.

This book offers a panorama of recent scientific achievements produced through the framework of the Large-Scale Biosphere-Atmosphere programme (LBA) and other research programmes in the Brazilian Amazon. The content is highly interdisciplinary, with an overarching aim to contribute to the understanding of the dynamic biophysical and societal/socio-economic structure and functioning of Amazonia as a regional entity and its regional and global climatic teleconnections. The target readership includes advanced undergraduate and post-graduate students and researchers seeking to untangle the gamut of interactions that the Amazon’s complex biophysical and social system represent.
The Amazon is a land of superlatives. The complex ecosystem covers an area about the size of the continental U.S. The Amazon River discharges 57 million gallons of water per second--in two hours, this would be enough to supply all of New York City's 7.5 million residents with water for a year. Its flora and fauna are abundant. Approximately one of every four flowering plant species on earth resides in the Amazon. A single Amazonian river may contain more fish species than all the rivers in Europe combined. It is home to the world's largest anteater, armadillo, freshwater turtle, and spider, as well as the largest rodent (which weighs over 200 lbs.), catfish (250 lbs.), and alligator (more than half a ton). The rainforest, which contains approximately 390 billion trees, plays a vital role in stabilizing the global climate by absorbing massive amounts of carbon dioxide--or releasing it into the atmosphere if the trees are destroyed. Severe droughts in both Brazil and Southeast Asia have been linked to Amazonian deforestation, as have changing rainfall patterns in the U.S., Europe, and China. The Amazon also serves as home to millions of people. Approximately seventy tribes of isolated and uncontacted people are concentrated in the western Amazon, completely dependent on the land and river. These isolated groups have been described as the most marginalized peoples in the western hemisphere, with no voice in the decisions made about their futures and the fate of their forests. In this addition to the What Everyone Needs to Know® series, ecologist and conservation expert, Mark J. Plotkin, who has spent 40 years studying Amazonia, its peoples, flora, and fauna. The Amazon offers an engaging overview of this irreplaceable ecosystem and the challenges it faces.
The Amazon Basin contains the largest and most diverse tropical rainforest in the world. Besides the Andes and the Atlantic Ocean, the rainforest is bounded to the north by the Guiana crystalline shield and to the south by the Brazilian crystalline shield, marked at their edges by cataracts in the rivers and often dominated by grasslands. This book is motivated not just by the Amazon's scientific interest but also by its role in many ecosystem functions critical to life on Earth. These ecosystems are characterized both by their complexity and their interactive, higher-order linkages among both abiotic and biotic components. Within Amazonia, the Western Amazon (west of 65° latitude) is the most pristine and, perhaps, the most complex within the Amazon Basin. This Western Amazon may be broadly divided into non-flooded forests (e.g. terra firme, white sand, palm) and forests flooded with white water (generally referred to as várzea) and with black water (generally referred to as igapó). Here, for the first time, is a book devoted entirely to Western Amazonia, containing chapters by scientists at the forefront of their own areas of expertise. It should be a valuable resource for all future researchers and scholars who venture into Western Amazonia, as it continues to be one of the most beautiful, mysterious, remote and important ecosystems on Earth.
"Rainforests occupy a special place in the imagination. Literary, historical and cinematic depictions range from a ghastly Green Hell to an idyllic Garden of Eden. In terms of fiction, they fired the already fervent imaginations of storytellers as diverse as Sir Arthur Conan Doyle, Edgar Rice Burroughs, Rudyard Kipling and even George Lucas and Steven Spielberg in whose books and films they are inhabited by dinosaurs, trod by Indiana Jones, prowled by Mowgli the Jungle Boy and swung through by Tarzan of the Apes. But rainforest fact is no less fascinating than rainforest fiction. Brimming with mystery and intrigue, these forests still harbor lost cities, uncontacted tribes, ancient shamans, and powerful plants than can kill - and cure. The rainforest bestiary extends far beyond the requisite lions, tigers and bears. Flying foxes and winged lizards, arboreal anteaters, rainforest giraffes, cross-dressing spiders that disguise themselves as ants and bats the size of a bumblebees all flourish in these most fabulous of forests along with other zoological denizens that are equally bizarre and spectacular. And no scientist immersed in these ecosystems believes that all the wonders have been found or revealed. Tropical rainforests merit their moniker. They flourish in the tropics - the more than 3000 mile-wide equatorial band between the Tropic of Cancer and the Tropic of Capricorn. And these forests are hot, humid and wet, receiving in the Amazon, on average from 60 to 120 inches of rain per year - as compared to a mere 25 inches in London or 45 inches in Manhattan. However, several sites in the rainforests of northeastern India, of west Africa and western Colombia are drenched by over 400 inches of precipitation per annum. To a large degree, rainfall in the tropics is determined by the so-called "Intertropical Convergence Zone" (ICZ), a band of clouds around the equator created by the meeting of the northeast and southeast trade winds. Also referred to as the "Monsoon Trough," and known to - and dreaded by - sailors over the centuries as the "Doldrums," since the extended periods of calm that sometimes manifested there could strand a sailing vessel for weeks. The constant cloud cover due to the ICZ, the ferocious heat, and the abundant rainfall combine to produce high humidity, sometimes close to 95 per cent in the Amazon, a challenge for visitors unused to such torpor. According to Rhett Butler of Mongabay: "Each canopy tree transpires 200 gallons of water annually, translating roughly into 20,000 gallons transpired into the atmosphere for every acre of canopy trees. Large rainforests (and their humidity) contribute to the formation of rain clouds, and generate as much as 75 per cent of their own rain and are therefore responsible for creating as much as 50 per cent of their own precipitation.""--
