Book Description
At the meeting of the International Tropical Timber Organization held in Bali in 1990, ITTO adopted the target of ensuring that all tropical timber marketed internationally should, by the year 2000, come from forests that are managed sustainably. This study is an attempt to determine whether the member countries of the ITTO have a legal and administrative basis for managing their production forests in ways which will allow these forests to contribute to biological diversity conservation. It also attempts to assess the extent to which such management is already applied on the ground through member country studies. A set of guidelines on ways in which management of production forests could be improved is included.

Book Description
Although biologists have directed much attention to estimating the extent and causes of species losses, the consequences for ecosystem functioning have been little studied. This book examines the impact of biodiversity on ecosystem processes in tropical forests - one of the most species-rich and at the same time most endangered ecosystems on earth. It covers the relationships between biodiversity and primary production, secondary production, biogeochemical cycles, soil processes, plant life forms, responses to disturbance, and resistance to invasion. The analyses focus on the key ecological interfaces where the loss of keystone species is most likely to influence the rate and stability of ecosystem processes.

Book Description
During the past century, tropical rain forests have been reduced to about half of their original area, with a consequent loss of biodiversity. This book takes a close look at how this has happened and what the consequences may be, with an emphasis on those strategies that have proven successful in stemming the loss of plant and animal inhabitants. It describes the use of protected areas such as sacred groves, royal preserves, and today's national parks, which have long served to shield the delicate forest habitats for countless species. Although programs for protecting habitats are under increasing attack, this book argues that a system of protected areas must in fact be the cornerstone of all conservation strategies aimed at limiting the inevitable reduction of our planet's biodiversity. Written by leading experts with years of experience, the book integrates ecological, economic and political perspectives on how best to manage tropical forests and their inhabitants, throughout the world. In addition to conservationists, policy makers, and ecologists, the book will serve as a useful text in courses on tropical conservation.

Book Description
This important book for scientists and nonscientists alike calls attention to a most urgent global problem: the rapidly accelerating loss of plant and animal species to increasing human population pressure and the demands of economic development. Based on a major conference sponsored by the National Academy of Sciences and the Smithsonian Institution, Biodiversity creates a systematic framework for analyzing the problem and searching for possible solutions.

Book Description
Biodiversity--the variety of genes, species, and ecosystems--is the basis for long-term ecosystem health and stability. Fifty percent of the world's biodiversity is inhabited in tropical forests. The world's biodiversity is diminishing and dwindling before our eyes at an alarming rate day by day. Half of the world's wetlands have been lost in the past century; 80 percent of grasslands are suffering from soil degradation; and 20 percent of drylands are in danger of becoming deserts. Every minute of the day, 28 hectares of forest are lost the world over. Wetlands and forests are being cleared for urban and industrial development and encroached upon by local people. Because of the irreversibility of species extinction and habitat loss, this rampant depletion of our biodiversity exerts a terrible toll on both the natural and economic world, affecting both current and future generations. It is the need of the hour to preserve and conserve biological diversity of all wetlands, forests and other ecosystems of the world. Seeing the importance of this, the United Nations designated the years 2011-2020 as the -United Nations Decade on Biodiversity.- This volume, Biodiversity of Tropical Wetlands and Forests, is the compiled research of Dr. Nirmal Kumar and his team over the last couple of decades on a diverse array of impacts on the biodiversity of tropical wetlands and forests. Divided into two parts, the volume provides valuable information on spatial and temporal fluctuations of phytoplankton, zooplankton, macrophytes, birds, and seaweed biodiversity of important tropical wetlands, including pond, lakes, rivers, mangroves, and estuarine and coastal environments. It looks at their relationships and interactions with various hydro-geochemical nutrients along with limiting factors and quantification of anthropogenic pressures. The second part of this book presents an evaluation of plant and tree biodiversity in relation to soil nutrient content, concentration, nutrient dynamics, ethnobotanical, aesthetic values, resources use patterns, phenology of floral elements, biomass, net primary productivity, carbon storage and greenhouse gas emissions from tropical forests, wildlife sanctuaries, and plantations. Providing a plethora of valuable information, the book will be a rich resource for researchers and students in the forestry, life sciences, environmental science, and related areas.

Book Description
Rain forests represent the world's richest repository of terrestrial biodiversity, and play a major role in regulating the global climate. They support the livelihoods of a substantial proportion of the world's population and are the source of many internationally traded commodities. They remain (despite decades of conservation attention) increasingly vulnerable to degradation and clearance, with profound though often uncertain future costs to global society. Understanding the ecology of these diverse biomes, and peoples' dependencies on them, is fundamental to their future management and conservation. Tropical Rain Forest Ecology, Diversity, and Conservation introduces and explores what rain forests are, how they arose, what they contain, how they function, and how humans use and impact them. The book starts by introducing the variety of rain forest plants, fungi, microorganisms, and animals, emphasising the spectacular diversity that is the motivation for their conservation. The central chapters describe the origins of rain forest communities, the variety of rain forest formations, and their ecology and dynamics. The challenge of explaining the species richness of rain forest communities lies at the heart of ecological theory, and forms a common theme throughout. The book's final section considers historical and current interactions of humans and rain forests. It explores biodiversity conservation as well as livelihood security for the many communities that are dependent on rain forests - inextricable issues that represent urgent priorities for scientists, conservationists, and policy makers.
