This book was released on with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aquatic ecosystem is a major subdivision of the biosphere, and covers almost 71% of the earth’s surface area. Coastal ecosystems mainly include estuaries, deltas, lagoons, mangrove forests, mudflats, salt marshes, salt pans, other coastal wetlands, ports and marinas, aquaculture beds, sea grass beds, coral reefs, and soft bottom environments above the continental shelf. Although coastal ecosystems represent only a small area of the world’s oceans, they are of great ecological and economic importance. Now-a-days, many of the coastal ecosystems of the world are being exploited for various development projects, resulting in deterioration of habitats and resources. Therefore, the present study focuses on two of such important coastal ecosystems such as estuary and mangrove. Estuary is a dynamic area with varying physical and topographical conditions, with neritic province, river delta, lagoon, backwater, mangroves, mudflat, and salt marsh, all being part of this vital area. Estuaries are important areas of human use for fisheries, transportation, aquaculture, and recreational pursuits. Thus, by virtue of their natural location and easy accessibility, estuaries are more amenable to anthropogenic influences. Mangroves are specialized ecosystems developed along estuarine seacoasts and river mouths in tropical and subtropical regions of the world, mainly in the intertidal zone. Hence, the mangrove ecosystem and its biological components are under the influence of both marine and freshwater conditions and have developed a set of physiological adaptations to overcome problems of anoxia, salinity and frequent tidal inundations. This has led to the assemblage of a wide variety of plant and animal species of special adaptations suited to the ecosystem. The book Pollution Status of Coastal Environment of Gulf of Khambhat, India covers an extensive study at Mahi Estuary and Vamleshwar Mangroves (Gulf of Khambhat), Gujarat, India. The authors have explored hydrochemistry, geochemistry, phytoplankton, zooplankton, and benthic community, along with site-specific conservation and their management strategies in both the marine environs. The book will be a ready reference to academicians, scientists, students, researchers, and marine authorities of the State as well as the Country, to enhance the knowledge in the field of mangroves and estuarine ecology, biodiversity, conservation, restoration, and management.

This book was released on with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 book will certainly be useful to students, researchers, academicians, scientists, and marine authorities of Gujarat as well as India, to enrich their knowledge in the field of ecology, biodiversity, conservation, restoration, and management of estuarine and gulf environs.

Available in PDF, EPUB and Kindle. Book excerpt: About the turn of the century the Apicomplexa plus some other groups were called Sporozoa. With the advent of the electron microscope, it was realized that most "Sporozoa" have an apical complex; those which do not (the Microspora, Myxozoa, and Ascetospora) were removed and the name Apicomplexa was put forward by Dr. Levine in 1970. Most of the important Apicomplexa fall into five main groups: the gregarines, haemogregarines (about which there is relatively little known), coccidia, haemosporids, and piroplasms. These two volumes classify, list (with synonyms and hosts) and give references to descriptions of the approximately 4600 species of Apicomplexa that have been named so far. Volume I contains an 8-page introduction and covers the gregarines and coccidia (including the haemogregarines). In volume II are the Sarcocystidae (the predator-prey coccidia) the haemosporids (the malaria and related parasites), the piroplasms, and some parasites of uncertain affinities. The Apicomplexa are divided into over 300 genera and more than 60 families, but this division is deceiving. Most of these groups contain only one or a few species. There are fewer than 50 genera with 10 or more named species, and only 8 with 100 or more. These 8 genera (Eimeria, Haemogregarina, Gregarina, Isospora, Haemoproteus, Plasmodium, Sarcocystis, and Babesia) comprise more than half of the species.

Available in PDF, EPUB and Kindle. Book excerpt: The growing number of published works dedicated to global environmental change leads to the realization that protection of the natural environment has become an urgent problem. The question of working out principles of co evolution of man and nature is being posed with ever-increasing persistence. Scientists in many countries are attempting to find ways of formulating laws governing human processes acting on the environment. Numerous national and international programs regarding biosphere and climate studies contribute to the quest for means of resolving the conflict between human society and nature. However, attempts to find efficient methods of regulating human activity on a global scale encounter principal difficulties. The major difficulty is the lack of an adequate knowledge base pertaining to climatic and biospheric processes as wen as the largely incomplete state of the databases concerning global processes occurring in the atmosphere, in the ocean, and on land. Another difficulty is the inability of modern science to formulate the requirements which must be met by the global databases necessary for reliable evaluation of the state of the environ ment and fore casting its development for sufficiently long time intervals.
