Book Description
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.

Book Description
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.

Book Description
Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.

Book Description
Freshwater Mycology: Perspectives of Fungal Dynamics in Freshwater Ecosystems presents chapters from expert contributors around the world. Through the contributed chapters, the contributors explore the perspectives of fungal dynamics in freshwater ecosystems, especially their diversity, distribution, functioning and role, biotransformation and bioprospecting potential, methodical advancements and metagenomic insights. Written with aquatic ecologists in mind, this book provides information on oceanic, estuarine and freshwater ecosystems not currently well understood and identifies new questions and answers about the roles of mycology in aquatic ecosystems. This topic is becoming an increasingly important area to understand due to the increasing global transports of microbes due to climate change and human actions. This is leading to a rapid loss of healthy freshwater ecosystems, the grave problem of antibiotic resistance, and the rarity of qualified mycology taxonomists and molecular systematicians. - Includes data from locations not previously or well covered from prior synthesis publications - Identifies new information on the roles of mycology in aquatic ecosystems - Provides insights into the fungal diversity of freshwater ecosystems, along with their potential roles

Book Description
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
