This book was released on 1977 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The unconfined open-water disposal resulting from the maintenance dredging of the Jordan Point - Windmill Point channel had an acute impact on the macrobenthic community. The fluid mud produced from the disposal operation probably had both physical and physiological effects on the fauna. Responses varied by species. Insects were the most sensitive and oligochaetes the least affected. Due to the resilience and opportunistic nature of the fauna the detectable impacts lasted less than 3 months. Fluid mud produced from disposal of fine-grained dredged material has properties and effects different than natural sediments. Its low density, instability and low oxygen concentration present severe problems of support, respiration and feeding of benthic organisms. (Author).
Download or read book The Ecology of Tidal Freshwater Marshes of the United States East Coast written by William E. Odum and published by . This book was released on 1984 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is part of a series of community profiles produced by the Fish and Wildlife Service to provide up-to-date information on coastal ecological communities of the tidal freshwater marsh community along the Atlantic coast from southern New England to northern Florida. Tidal freshwater marshes occupy the uppermost portion of the estuary between the oligohaline or low salinity zone and nontidal freshwater wetlands. By combining the physical process of tidal flushing with the biota of the freshwater marsh, a dynamic, diverse, and distinct estuarine community has been created. The profile covers all structural and functional aspects of the community: its geology, hydrology, biotic components, and energy, nutrient and biomass cycling.

Download or read book The Pollution Biology of Aquatic Oligochaetes written by Pilar Rodriguez and published by Springer Science & Business Media. This book was released on 2011-08-30 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: In aquatic ecosystems, the oligochaetes are often a major component of the community. Their relevance in sediment quality assessment is largely related to their benthic and detritivorous life habit. In this book, we aim to present the state of the art of Pollution Biology using oligochaete worms in laboratory and field studies. Future research will require the combination of a variety of methodological approaches and the integration of the resulting information, avoiding fragmented and often conflicting visions of the relationships of the species with their environment. Current approaches to ecotoxicology and bioaccumulation using ecological risk assessment provide the opportunity to relate community studies with probability of effects. This book addresses three main themes: Ecological and Field Studies using the composition and structure of oligochaete communities, Toxicology and Laboratory Studies, and Bioaccumulation and Trophic Transfer Studies. Two appendices list values of toxicological parameters (LC50, EC50) and several bioaccumulation variables (bioaccumulation factors, biological half-life, toxicokinetic coefficients, and critical body residues) for different oligochaete species. Additional information is provided on Methodological Issues and on the Taxonomy of several oligochaete families, with information on the most recent taxonomic debates. Each chapter includes a critical view, based on the authors’ experience, of a number of current issues which have been raised in the literature.

This book was released on 2012-12-06 with total page 602 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of a symposium held at the College of Charleston, Charleston, South Carolina, USA, 16-20 June 1986. The seed for this symposium arose from a group of physiologists , soU scientists and biochemists that met in Leningrad, USSR in July 1975 at the 12th Botanical Conference in a Session organized by Professor B.B. Vartepetian. This group and others later conspired to contribute to a book entitled Plant Life in Anaerobic Environments (eds. D. D. Hook and R. M. M. Crawford, Ann Arbor Science, 1978). Several contributors to the book suggested in 1983 that a broad-scoped symposium on wetlands would be useful (a) in facilitating communication among the diverse research groups involved in wetlands research (b) in bringing researchers and managers together and (c) in presenting a com prehensive and balanced coverage on the status of ecology ami management of wetlands from a global perspective. With this encouragement, the senior editor organized a Plan ning Committee that encompassed expertise from many disciplines of wetland scientists and managers. This Committee, with input from their colleagues around the world, organized a symposium that addressed almost every aspect of wetland ecology and management.
Download or read book Sediment Toxicity Assessment written by G.Allen Burton and published by CRC Press. This book was released on 2018-05-04 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sediment Toxicity Assessment provides the latest information regarding how to evaluate sediment contamination and its effects on aquatic ecosystems. It presents an integrated ecosystem approach by detailing effective assessment methods, considerations, and effects to each major component of marine and freshwater systems, including the benthos, plankton, and fish communities. The approaches emphasize defining habitat conditions (physical and chemical), toxicant bioavailability, factors influencing toxicity (lab and field), biomarkers, acute and chronic toxicity, study design, collection methods, and EPA management strategies. The book also explains how to integrate the assessments. Sediment Toxicity Assessment will be useful to to all environmental managers, environmental scientists, ecotoxicologists, environmental regulators, aquatic ecologists, environmental contractors and consultants, instructors, students, conservation commissions, and environmental activist organizations.
