Aquatic Ecosystems Interactivity Of Dissolved Organic Matter

Overviews of the source, supply and variability of DOM, surveys of the processes that mediate inputs to microbial food webs, and syntheses consolidating research findings provide a comprehensive review of what is known of DOM in freshwater. This book will be important to anyone interested in understanding the fundamental factors associated with DOM that control aquatic ecosystems."--BOOK JACKET.

The Biology of Particles in Aquatic Systems, Second Edition presents the latest information on particulate and dissolved matter found in aquatic habitats ranging from small streams to oceans. Only by studying this matter can we gain an understanding of the functioning of aquatic ecosystems and thus be able to predict changes that may occur as these systems become stressed. Updated and extensively revised, this new edition covers such topics as classification of particulate and dissolved matter, origin and formation of particles aquatic systems, factors affecting particle aggregation, methods for capturing particles by benthic and planktonic animals, and the use of particulate and dissolved organic matter as food.

Organic Acids in Aquatic Ecosystems E. M. Perdue E. T. Gjessing Editors This volume consists of background papers and reports on discussions focused on identifying major processes that cause spatial and temporal variability in properties and concentrations of organic acids in aquatic ecosystems. Scientists in aquatic chemistry, environmental chemistry, soil chemistry, organic geochemistry, water treatment technology, forest ecology, and stream ecology collectively address four major questions: What is the composition of organic acids and how are they characterized? How are acid-base properties of "DOC" measured and modeled and how do they affect aquatic ecosystems? How do organic acids interact with solutes, surfaces, and organisms? What are the temporal and spatial variations of organic acids at the ecosystem level? This volume provides an up-to-date assessment of the state of knowledge of organic acids in aquatic ecosystems and identifies promising areas of new research that deserve the attention of all scientists who study chemical and biological processes in natural waters, where the importance of organic acids in such processes is not yet fully recognized.
