Book Description
Aquatic ecosystems are diverse habitats, endowed with physical, chemical, and geographical variations in the world, where the gradation from highly productive organisms to highly specialized organisms exists. The Mother Planet (Earth) is the only one in our solar system, characterized and shaped by abundant liquid; water - a necessity for life. Although water characterizes this planet, majority of it is saline in nature (97.2%) and contained in the world's ocean. Only 2.8% is fresh water, including 2.05% frozen in glaciers, 0.68% as groundwater, and only a tiny fraction (0.011%) of our water resources is contained in freshwater i.e. ponds, rivers and lakes. This water is available first in the form of surface water through rivers and lakes. The river is a prime example of lotic ecosystem. It is a wide, natural stream of fresh water that flows into an ocean, and is usually fed by smaller streams, called tributaries that enter it along its course. A river and its tributaries form a drainage basin or watershed that collects the run-off throughout the region and channels along with erosional sediments toward the river. Rivers are described by unidirectional flow, continuous state of physical change, high degree of spatial and temporal heterogeneity including biotic (aquatic plant, organisms and plankton) as well as abiotic (physical and chemical) interactions. There are 14 major rivers, 44 medium rivers and 53 small rivers in India. Major rivers have been proved to be the seat for the setup of big cities and their educational, political and regional developments. The state of Gujarat has been profusely endowed with number of perennial rivers such as Narmada, Tapi, Mahi and Sabarmati. The book Trophodynamics, Biodiversity and Conservation of Rivers of Gujarat focuses on environmental, ecological, and biological studies of two major rivers viz. Banas and Meshwo, Western Gujarat, India, covering abiotic and biotic components, eutrophication, hydrochemistry, geochemistry, phytoplankton, zooplankton, and streamers (macroinvertebrates). The book highlights an in-depth study of surface water and bottom sediment quality, diversity, density, abundance, commonness, rarity of plankton including qualitative and quantitative characters, diversity indices, population dynamics of streamers, and correlation between abiotic and biotic components. The book would unquestionably be the need of an hour for wetland managers, riverine conservationists, and policy makers or decision authorities to prevent the unrestrained exploitation of stream biodiversity, destruction of potential riverine habitats, and uncontrolled interactions of man and technology with lotic ecosystems of the world.

Book Description
Wetlands occur expansively all over the world in all the climatic zones and are appraised to harbour nearly 6.4% of the Earth’s surface, of which India domiciles about 18.4% of global wetlands and Gujarat 36% of country wetlands. As per Millennium Ecosystem Assessment (MEA), wetlands deliver 45% of the world’s natural productivity and ecosystem services of which the benefits are estimated at $20 trillion a year. Thus, wetlands exhibit enormous diversity according to their genesis, geographical location, water regime and chemistry, dominant plants and soil or sediment characteristics. Wetlands directly and indirectly support millions of people in providing services such as food, fibre and raw materials, storm and flood control, clean water supply, scenic beauty and educational and recreational benefits. Apart from beneficiary contribution of wetlands to the ecosystem, biotic and abiotic components, and human inhabitants, the very subsistence of these unique natural resources is under intimidation due to developmental activities, population pressure, and anthropogenic stress. Globally, the areal extent of wetland ecosystems ranges from 917 million hectares (m ha) to more than 1275 m ha with an estimated economic value of about USD 15 trillion a year. Overall, 1052 Sites in Europe; 289 Sites in Asia; 359 Sites in Africa; 175 Sites in South America; 211 Sites in North America; and 79 Sites in Oceania region have been recognized as per international recognition for designation to be handled under protected areas. It gives us an immense pleasure in presenting this comprehensive book on Ecosystem Analysis of Two Tropical Community Reservoirs of India. This book covers an extensive research on two significant wetlands of national importance of Central Gujarat, India, listed in ‘Asian Directory of Wetlands’, highlighting point and non-point sources of pollution, nutrient budget and recycling of nutrients in surface water and bottom sediments, planktons as indicators and markers of pollution, macrophytes as indicators of quality of wetlands, suitability of habitat for waterfowl conservation, and conservation and site-specific management strategies for sustainable use of biotic resources with recommendations and mitigating measures. We hope that this book will be of a great help to students, teachers, scientists, wetland conservationists, policy makers and government authorities, in enhancing their knowledge in the field of wetland ecology, biodiversity, conservation, restoration, and management for sustaining prevailing abiotic and biotic resources for better future.

Book Description
Estuaries are among the most complex and complicated ecosystems in the biosphere because they are at the interface of terrestrial, freshwater, and marine systems. Estuaries and the lands surrounding them are places of transition from land to sea and from fresh to salt water. Although influenced by the tides, estuaries are protected from the full force of ocean waves, winds, and storms by the reefs, barrier island or fingers of land, mud or sand that define an estuary's seaward boundary. In India, estuaries have been a focal point of activities for human settlement, for development of port and harbors. The health status and the biological diversity of the Indian estuarine ecosystem are deteriorating day-by-day through man-made activities and dumping of enormous quantities of sewage and industrial effluent. Estuaries are ecologically very important because it provides vital habitats for thousands of marine species. They are "nurseries of the sea", as it is an ideal location for fish, shellfish, and other marine animals to reproduce in protected environment and availability of abundant food. Besides, estuaries are important for the health of the oceans as it can filter sediment and pollutants from the water before it flows into the oceans. Estuaries are vulnerable to excessive loading of nutrients by runoff containing fertilizer and other pollutants. In recent decades, population growth and related activities (agricultural practices, wastewater treatment plants, urban run-off, and the burning of fossil fuels) have increased nutrient inputs by many folds than the levels that occur naturally. The present book Eutrophic Status of Narmada and Tapi Tropical Estuaries of Gujarat, India point-out an intensive study at two major estuaries (Narmada, Tapi) of Gujarat, India. The authors have investigated hydrochemistry, geochemistry, phytoplankton, zooplankton, and benthic community, along with site-specific problems and their suggestions in both the estuarine environs. This book will certainly be a ready reference guide to the students, researchers, academicians, scientists, and riverine and marine authorities of Gujarat and India, to enrich their knowledge in cutting edge of research in the field of estuarine ecology, biodiversity, conservation, restoration, and management.

The Gujarat State is profusely endowed with a number of perennial rivers such as Narmada, Tapi, Mahi and Sabarmati. The book Pollution Studies of Sabarmati River and Kharicut Canal, Ahmedabad, Gujarat focuses on environmental, ecological, and biological studies of two rivers viz. Sabarmati (River Front) and Kharicut Canal (Industrial River), Central Gujarat, India, covering abiotic (hydrochemical characteristics, geochemical characters), nutrient budget, recycling of nutrients, biotic components (microbial analysis: Total Coliform, Faecal Coliform; phytoplankton, zooplankton), eutrophic status, and heavy metals in surface water and bottom sediment. The book also highlights an in-depth study of surface water and bottom sediment quality, diversity, density, abundance, commonness, rarity of plankton (phytoplankton, zooplankton) including qualitative and quantitative characters, diversity indices, population dynamics, and correlation between abiotic and biotic components. The book would indubitably be a standard reference guide for riverine conservationists, river managers, policy makers, and decision makers to prevent the unrestrained exploitation of stream biodiversity, destruction of potential riverine habitats, and uncontrolled interactions of man and technology with lotic ecosystems of the world.
