Biological diversity encompasses all species of animals, plants, micro-organisms, ecosystem and ecological processes of which they are part. Biodiversity provides the basis for life on earth. The more we know about Earth's biological diversity, the better will be our capability to conserve both terrestrial and aquatic ecosystems. Expanding human population, overexploitation of natural resources, habitat loss and pollution are contributing to a great extent to the rapid degradation of environmental quality, with its irreversible loss or depletion of species diversity. The current perception is therefore to frame strategies to conserve biodiversity otherwise the future generation will blame us for robbing them for their life support systems. This book includes original research articles on various aspects of Biodiversity and its Conservation presented by eminent Scientists working within the country and abroad. Most of the concepts are new and pertinent to Indian context. This book will be of immense utility to the Researchers and Post-Graduate students engaged in varied areas of Biodiversity conservation.
