Download or read book Complex Interactions in Lake Communities written by Stephen R. Carpenter and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Texas Aquatic Science written by Rudolph A. Rosen and published by Texas A&M University Press. This book was released on 2014-11-19 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Freshwater Biodiversity written by David Dudgeon and published by Cambridge University Press. This book was released on 2020-05-21 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Laboratory Procedure for Estimating Residue Dynamics of Xenobiotic Contaminants in a Freshwater Food Chain written by Byron Thomas Johnson and published by . This book was released on 1980 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: A laboratory method of measuring the accumulation, transfer, elimination, and degradation of xenobiotic contaminants is described for organisms in a freshwater food chain (microorganisms, filter-feeder, and fish). A flow-through diluter-syste, C14-labeled contaminants, gas and thin-layer chromatography, autoradiography, and liquid scintillation spectrometry are used in making residue determinations. Accumulation factors and various index values are developed for measuring and estimating potential accumulation of xenobiotic contaminants by aquatic organisms. The laboratory procedure is economical, simple, reproducible, and ecologically relevant.

Download or read book Freshwater Mycology written by Suhaib A. Bandh and published by Elsevier. This book was released on 2022-05-27 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
