Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.

This book offers a comprehensive account of India's four biodiversity hotspots: the Himalaya, Indo-Burma, Western Ghats and Sri Lanka and Andaman and Nicobar Islands. With a focus on tropical rainforests, it includes more than 30 chapters covering different vertebrate fauna e.g. fishes, amphibians, reptiles, birds, and mammals, as well as topics such as conservation and management aspects. Written by experts in the field of biodiversity conservation and management, it offers ample new insights into a number of subjects related to the faunal communities of tropical forest ecosystems, providing a valuable resource for conservationists and researchers in the field of flora and fauna diversity.

Biodiversity is declining at an alarming rate due to anthropogenic activities around the world. This book is the first volume in the new series Biodiversity Hotspots of the World, which highlights the 36 hotspot regions of the world, regions that were designated as reaping maximum benefit from preservation efforts. This series is our humble attempt to document these hotspots as a conservation and preservation measure. This first volume in the series focuses on the Western Ghats and Sri Lanka, construed as forming a community of species because of their shared biogeographical history. The volume explores the diversity and conservation efforts of the extraordinarily rich species found here, including plants, many of which are found nowhere else in the world; forests, which face tremendous population pressure and have been dramatically impacted by demands for timber and agricultural land; as well as the hotspot’s diverse mammals, birds, insects, and amphibian species, and more. The volumes in this series will be essential resources for researchers and practitioners in the fields of conservation biology, ecology, and evolution.

Microbial Diversity in Hotspots provides an introduction to microbial diversity and microbes in different hotspots and threatened areas. The book gives insights on extremophiles, phyllosphere and rhizosphere, covers fungal diversity, conservation and microbial association, focuses on biodiversity acts and policies, and includes cases studies. Microbes explored are from the coldest to the hottest areas of the world. Although hotspots are zones with extremely high microbiology activities, the knowledge of microbial diversity from these areas is very limited, hence this is a welcome addition to existing resources. - Provides an introduction to microbial biotechnology - Addresses novel approaches to the study of microbial diversity in hotspots - Provides the basics, along with advanced information on microbial diversity - Discusses the techniques used to examine microbial diversity with their applications and respective pros and cons for sustainability - Explores the importance of microbial genomes studies in commercial applications

On the Malabar Coast of southern India, along the Arabian Sea, lies a range of mountains known as the Western Ghats, or Sahyadris. Far more ancient than the larger and better-known Himalayas to the north, the Sahyadris harbour the most intact rainforests in peninsular India. Countless species of plants and animals live here, many of which are found nowhere else on earth, and countless of which are still being discovered. Matching this incredible biological richness is the ethnic and cultural diversity of the Western Ghats. This book takes you on a visual journey through one of the last great places on earth - a place to be cherished, a wild heritage to be preserved for generations to come.

The Living Elephants is the authoritative resource for information on both Asian and African elephants. From the ancient origins of the proboscideans to the present-day crisis of the living elephants, this volume synthesizes the behavior, ecology and conservation of elephants, while covering also the history of human interactions with elephants, all within the theoretical framework of evolutionary biology. The book begins with a survey of the 60-million year evolutionary history of the proboscideans emphasizing the role of climate and vegetation change in giving rise to a bewildering array of species, but also discussing the possible role of humans in the late Pleistocene extinction of mastodonts and mammoths. The latest information on the molecular genetics of African and Asian elephants and its taxonomic implications are then presented. The rise of the elephant culture in Asia, and its early demise in Africa are traced along with an original interpretation of this unique animal-human relationship. The book then moves on to the social life of elephants as it relates to reproductive strategies of males and females, development of behavior in young, communication, ranging patterns, and societal organization. The foraging strategies of elephants, their impact on the vegetation and landscape are then discussed. The dynamics of elephant populations in relation to hunting for ivory and their population viability are described with the aid of mathematical models. A detailed account of elephant-human interactions includes a treatment of crop depredation by elephants in relation to their natural ecology, manslaughter by elephants, habitat manipulation by humans, and a history of the ivory trade and poaching in the two continents. The ecological information is brought together in the final chapter to formulate a set of pragmatic recommendations for the long-term conservation of elephants. The broadest treatment of the subject yet undertaken, by one of the leading workers in the field, Raman Sukumar, the book promises to bring the understanding of elephants to a new level. It should be of interest not only to biologists but also a broader audience including field ecologists, wildlife administrators, historians, conservationists and all those interested in elephants and their future.

India’s phytodiversity is one of the most significant in the world. India is one of the twelve mega-biodiversity centers in the world and also an important center of origin of agrobiodiversity. It is therefore, very important to study, document and conserve the plant wealth of India and also of the world before its possible extinction. There are convincing scientific, economic and sociological reasons for giving priority to the conservation of the major centers of plant diversity throughout the world. The strategies to conserve the biodiversity include establishment of protected area network and corridors with emphasis on appropriate levels of management, reduction of anthropogenic pressure on natural populations by cultivating them elsewhere, programmes of augmentation, reintroduction and introduction of target taxa, restoration of degraded habitats, etc. The conservation strategies can be either, in-situ conservation of genetic resources within their ecosystem and natural habitat or ex-situ conservation of components of genetic material of biological diversity outside their natural habitat. The choice of conservation strategy depends upon the nature of the material to be conserved, i.e., the life cycle and mode of reproduction, size of individual population and ecological status. Ex-situ techniques include the establishment of botanical and zoological gardens, banks of pollen, seed tissue culture, DNA, etc. Establishment of forest reserves, national parks, protected areas and on farm conservation of valuable plant varieties is being promoted to facilitate their in-situ conservation.
