This contributed book is based on the current status of biodiversity in India, issues and challenges faced by the authorities involved in conservation efforts, and the imperative role of various direct and indirect stakeholders in biodiversity conservation. The book discusses the current status of different forms of biodiversity in India, challenges faced by stakeholders, issues and reasons for biodiversity losses, and efforts by government through various laws, policies, and programs in a concise and comprehensive manner throughout its many chapters. In this way, readers can access diverse information on Indian biodiversity through this book. It is compiled by leading experts in the field of conservation. In 18 chapters, it covers biodiversity of both fauna and flora, on land and in aquatic ecosystems, legal and policy aspects, as well as innovative conservation tool and techniques. It is useful for undergraduates and graduate students and also educates policy planners, bureaucrats, foresters, and researchers in India and abroad.
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.
The present book has been designed to bind prime knowledge of climate change-induced impacts on various aspects of our environment and its biological diversity. The book also contains updated information, methods and tools for the monitoring and conservation of impacted biological diversity.

The present book reflects the present scenario of Aquatic Biodiversity in India. The book includes 22 chapters contributed by eminent scientists, researchers and teachers, who all are leading authorities in the field of aquatic biodiversity. The book covers in depth analysis of aquatic flora and fauna, their present status in India, various threats to them and their conservation measures. The book forms a useful contribution for Limnologists, Zoologists, Botanists, Microbiologists, Environmentalists, Researchers, students of PG level and for the people engaged in the field of aquatic biodiversity.
Understanding the balance of society and nature is imperative when researching ecosystems and their global influence. A method of studying the health of these ecosystems is biodiversity. The more diverse the species that live in an ecosystem, the healthier it is. As the climate continues to transform, small-scale ecosystems are affected, altering their diversity. Environmentalists need a book of research that studies the specific impacts of climate change and how it affects the future of the environment. Current State and Future Impacts of Climate Change on Biodiversity is a pivotal reference source that provides vital research on biological systems and how climate change influences their health. While highlighting topics such as genetic diversity, economic valuation, and climatic conditions, this publication explores the effects of climate change as well as the methods of sustainable management within ecosystems. This book is ideally designed for environmental scientists, environmental professionals, scientists, ecologists, conservationists, government officials, policymakers, agriculturalists, environmentalists, zoologists, botanists, entomologists, urban planners, researchers, scholars, and students seeking research on current and future developments of various ecosystems.
More than 70% of the earth's surface is covered by water, making it an ideal and abundant resource for studying species diversity, faunal communities, and ecosystems. India's massive coastline (5,044 miles) means it plays a major role in housing these faunal communities. Of the 32 animal phyla, 15 are represented in India's marine ecosystem, covering more than 15,000 species. Marine and coastal ecosystems of India provide supporting services in the form of wide range of habitats. Major ecosystems such as estuaries, mangroves, coral reefs, lagoons, seaweeds and sea grasses serve as nurseries for both inshore and offshore fishes and others, many of which are supposed to be commercially exploited. Marine Faunal Diversity in India describes different marine faunal group ranges from sponges, corals, mollusks, crabs, fishes, reptiles, birds, marine mammals, mangrove fauna and tsunami impact on marine faunal diversity. The chapters, written by reputed experts in their respective fields, illustrate diversity and distribution of marine faunal communities. Key aspects of the ecology and conservation of this important ecosystem are also discussed. Marine Faunal Diversity in India provides marine biologists and related researchers with access to the latest research and field studies from this major region. - Provides the latest field research on marine faunal diversity throughout the vast and species-rich Indian region - Brings together expertise from top marine biology researchers in the country - Covers a diverse array of aquatic environments, including coastal and island areas - Discusses conservation ecology of marine faunal groups
Insects are the most interesting and diverse group of organisms on earth, many of which are useful as pollinators of crops and wild plants while others are useful as natural enemies keeping pestiferous insects in check. It is important to conserve these insects for our survival and for this the diversity of insect species inhabiting the different ecosystems of our country must be known. The cornerstone to studies of any kind of organismal diversity is their taxonomic identity. Even after over two and half centuries of studies, so little is known of the insect wealth of our country. It has contributions from taxonomists who have been studying Indian insects for long, this book offers up to date information on many important groups of Indian insects seeking to fill the lacuna of a long felt need for a comprehensive work on the taxonomy of Indian insects. Salient features: Provides an up-to-date taxonomy of major insect groups of India Presents identification keys with illustrations of several important groups of Indian insects Gives a new insight into why insects are so abundant Addresses fundamental questions in mechanoreception and cross kingdom interactions using insects as model systems Indian Insects: Diversity and Science is a festschrift to Professor C. A. Viraktamath, an insect taxonomist par excellence. It has been designed to cater to the needs of academicians, researchers and students who wish to identify insects collected from local environments and will be an invaluable aid for those working in the areas of systematics, ecology, behaviour, diversity and the conservation of insects.
