This book presents a compendium of molecular biology applications for the study of aquatic community ecology. The collection presents the diversity of approaches that have been used, and provides future directions for the study of `molecular ecology' of aquatic communities, from viruses to fish, and in aquatic systems ranging from freshwater streams and lakes to estuaries and oceans. This collection of papers will provide a useful text and resource for upper-level undergraduate and graduate students in ecology, as well as for the researcher and educator.

Aquatic microbial ecology, a growing interdisciplinary field, has become increasingly compartmentalized in recent years. The aim of this volume is to propose a framework for biochemical and molecular approaches, which are employed ever more widely in studies of aquatic microbial communities and ecosystem functioning. The book presents state of the art applications of modern molecular research techniques to a range of topics in ectoenzymes microbial carbon metabolism bacterial population dynamics RNA chemotaxonomy of microbial communities plasmids and adaptation to environmental conditions. Written for limnologists, marine biologists, and all researchers interested in environmental microbiology and molecular aspects of ecology, this volume will provide a stimulating introduction to this emerging field.

A NATO ASI on "Molecular Ecology of Aquatic Microbes" was held at II Ciocco, Lucca, Italy from 28 August - 9 September 1994. The aims of the ASI were to evaluate the potential for molecular biology to solve some important questions in aquatic microbiology, particularly in relation to biogeochemical cycling and microbial physiology. Techniques developed by molecular biologists have now been adopted by a wide range of scientific disciplines. In the last 5 years, aquatic microbial ecologists have begun to incorporate these methods into their research and, as a result, are developing a much clearer understanding of phylogenetic diversity, the molecular basis of physiological acclimations and the transduction of environmental signals and organism responses. The aim of this ASI was to assess progress in this new field of research, to compare and describe techniques and experimental approaches, and to foster communication between disciplines. The ASI offered an excellent opportunity to bring together aquatic ecologists with molecular biologists and to encourage efficient technology transfer. The meeting of information on the status provided a forum for detailed and broad exchange and trends of aquatic molecular ecology and to assess how emerging molecular techniques might solve some important problems in ecology which have prove intractable because of lack of appropriate methodologies.

The cyanobacteria inhabit every illuminated environment on Earth, from polar lakes to desert crusts and through their phototrophic metabolism play essential roles in global geochemical cycles. With the discovery of marine Synechococcus and Prochlorococcus almost 30 years ago, cyanobacteria have now earned their place as dominant primary producers contributing over 25 percent of global photosynthesis. Their global abundance is now explained from the coexistence of ecotypes that occupy different niches along spatial and temporal gradients. New ecotypes of Synechococcus have been identified as abundant components of microbial communities in freshwater environments and marginal seas. Extensive comparative genomics of marine and freshwater picocyanobacteria have begun to unmask adaptations to light and nutrient (N, P, Fe) limitation that these diverse environments present. Novel types of cyanobacterial diazotrophy input new N and structure microbial communities in the open sea. Current challenges include the understanding of the interactions between marine cyanobacteria and other microbes in their immediate community. In contrast, mesotrophic and eutrophic environments such as the Laurentian Great Lakes have been increasingly affected by nuisance and toxic cyanobacterial blooms that have yielded severe declines in water quality. Factors promoting bloom formation and the functional roles of toxins are important issues being addressed today.

In its statutory authority (National Science Foundation Act of 1950, as amended), the NSF is directed to both initiate and support basic scientific research. In its Ecology Program, one mode of initiating research is to en courage the development of new ideas through advisory workshops. The NSF is specifically directed to strengthen our nation's research potential. In addition, stimulating new approaches to research will continue to be prominent in the coming years as federal attention is given to increasing the innovativeness and competitiveness of the U. S. in science and engineering. A decision to initiate a workshop does not arise de novo in the Ecology Program. Rather, it emerges from panel discussions, conversations with in vestigators at meetings or on the phone, and from discussions between pro gram officers in the Division of Biotic Systems and Resources. This workshop was developed to provide advice to the NSF and the lim nological community. Some NSF perceptions on future funding for ecolog ical research on lake communities are presented here. Researchers often mentioned a paucity of innovative lake ecology at the community level. This perception was accompanied by a certain frustration since lakes probably have the best empirical data base of any natural environment and should continue to lead in the development of ecological concepts. Members of NSF advisory panels sometimes expressed similar concerns during consid eration of proposals for lake research.

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.

Freshwater Ecology, Second Edition, is a broad, up-to-date treatment of everything from the basic chemical and physical properties of water to advanced unifying concepts of the community ecology and ecosystem relationships as found in continental waters. With 40% new and expanded coverage, this text covers applied and basic aspects of limnology, now with more emphasis on wetlands and reservoirs than in the previous edition. It features 80 new and updated figures, including a section of color plates, and 500 new and updated references. The authors take a synthetic approach to ecological problems, teaching students how to handle the challenges faced by contemporary aquatic scientists. This text is designed for undergraduate students taking courses in Freshwater Ecology and Limnology; and introductory graduate students taking courses in Freshwater Ecology and Limnology. Expanded revision of Dodds' successful text. New boxed sections provide more advanced material within the introductory, modular format of the first edition. Basic scientific concepts and environmental applications featured throughout. Added coverage of climate change, ecosystem function, hypertrophic habitats and secondary production. Expanded coverage of physical limnology, groundwater and wetland habitats. Expanded coverage of the toxic effects of pharmaceuticals and endocrine disrupters as freshwater pollutants More on aquatic invertebrates, with more images and pictures of a broader range of organisms Expanded coverage of the functional roles of filterer feeding, scraping, and shredding organisms, and a new section on omnivores. Expanded appendix on standard statistical techniques. Supporting website with figures and tables - http://www.elsevierdirect.com/companion.jsp?ISBN=9780123747242
