This book provides an opportunity to understand the cause-effect relation between water resources development interventions and brackish water ecosystems in a developing country like Bangladesh. Because of the increasing water development interventions in Bangladesh, brackish water ecosystems have become a great concern at the present time. Being located in the south-eastern coastal area of Bangladesh, the Bakkhali River faces such type of threat. Due to the rubber dam construction across the river, the brackish water zone has been cut-off by establishing a distinct fresh and saline water zone affecting livelihoods of the brackish water dependent groups. The study reveals low availability of the indicator species in the zone. Finally, the study also argues that the impact on indicator species is due not only to the rubber dam construction across the river but also increased fisher folks and indiscriminate fishing practice considerably.

This classroom resource provides clear, concise scientific information in an understandable and enjoyable way about water and aquatic life. Spanning the hydrologic cycle from rain to watersheds, aquifers to springs, rivers to estuaries, ample illustrations promote understanding of important concepts and clarify major ideas. Aquatic science is covered comprehensively, with relevant principles of chemistry, physics, geology, geography, ecology, and biology included throughout the text. Emphasizing water sustainability and conservation, the book tells us what we can do personally to conserve for the future and presents job and volunteer opportunities in the hope that some students will pursue careers in aquatic science. Texas Aquatic Science, originally developed as part of a multi-faceted education project for middle and high school students, can also be used at the college level for non-science majors, in the home-school environment, and by anyone who educates kids about nature and water.

A knowledge, which is as accurate as possible of microbial ecology is indispensible for ecosystem research and environmental protection. This is particularly true for coastal waters, whereby brackish water areas occupy a special position. After several years of preliminary studies on the composition and distribution of the micro flora -algae, fungi, and bacteria -a comprehensive investigation on the primary production, bacterial development and microbial uptake and decom position of substances in the Kie1 Bight was carried out, during which ten scientists from the Institut fUr Meereskunde ofKiel University participated. Here forthe first time numerous hydrographical, chemical and microbiological parameters could be measured on the same water samples. The aim of this joint project was to gain an insight into the manifold functions of the microorganisms in the uptake and degradation of organic substances and in the connections between pollution, production, and remineralization. The results ofthe investigations led not only to new knowledge of the role ofthe microorganisms in the brackish water ecosystem, but also to a revision of earlier conceptions, especially on the influence of wastes on the micro flora and its role in the self-purification of coastal waters. Such a time-limited investigation, however, cannot clarify all the questions on the complex relationships between the microorganisms and their biotope. Therefore, the present volume should also be understood as a stimulus for new and further-reaching research on the microbial ecology of coastal waters. Thereby the most important methods are described, as well as the practical experience obtained.

Rather than a marginal part of protected area management, this book shows that freshwater conservation is central to sustaining biodiversity. It focuses on better practices for conserving inland aquatic ecosystems in protected areas (PAs), including rivers, wetlands, swamps, other brackish and freshwater ecosystems, and coastal estuaries.
