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.

Available in PDF, EPUB and Kindle. Book excerpt: Reflecting the recent surge of activity in food web research fueled by new empirical data, this authoritative volume successfully spans and integrates the areas of theory, basic empirical research, applications, and resource problems. Written by recognized leaders from various branches of ecological research, this work provides an in-depth treatment of the most recent advances in the field and examines the complexity and variability of food webs through reviews, new research, and syntheses of the major issues in food web research. Food Webs features material on the role of nutrients, detritus and microbes in food webs, indirect effects in food webs, the interaction of productivity and consumption, linking cause and effect in food webs, temporal and spatial scales of food web dynamics, applications of food webs to pest management, fisheries, and ecosystem stress. Three comprehensive chapters synthesize important information on the role of indirect effects, productivity and consumer regulation, and temporal, spatial and life history influences on food webs. In addition, numerous tables, figures, and mathematical equations found nowhere else in related literature are presented in this outstanding work. Food Webs offers researchers and graduate students in various branches of ecology an extensive examination of the subject. Ecologists interested in food webs or community ecology will also find this book an invaluable tool for understanding the current state of knowledge of food web research.

This book was released on 2012-12-06 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Limnology is increasingly concerned with water supply and the relation of man to aquatic environments. Without the continued availability of pure water, all progress in technology and other fields of human life will be to no avail. The global problems concerning clear water are already extremely pressing. More limnology knowledge is needed to solve these problems. The responsibility of man to save water and to take more intensive care of the environment is raised in many of the papers, in this book. This emphasizes the necessary and unquestionable relevance of limnology to human society. Too often the abuse of water usage reflects the neglect of scientific results. Limnologists have a responsibility to ensure that administrators understand what is going on. The coverage of the book is wide, including papers on microbiology to engineering sciences. The biology of waters is handled at both species and ecosystem levels. The geographical distribution of topics ranges from the tropics to northern temperate areas. In fact, limnology is increasingly becoming a science which is, rightly, relevant to everyday life, not just an academic subject.

Download or read book Large Lakes written by Max M. Tilzer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 699 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vast majority of the world's lakes are small in size and short lived in geological terms. Only 253 of the thousands of lakes on this planet have surface areas larger than 500 square kilometers. At first sight, this statistic would seem to indicate that large lakes are relatively unimportant on a global scale; in fact, however, large lakes contain the bulk of the liquid surface freshwater of the earth. Just Lake Baikal and the Laurentian Great Lakes alone contain more than 38% of the world's total liquid freshwater. Thus, the large lakes of the world accentuate an important feature of the earth's freshwater reserves-its extremely irregular distribution. The energy crisis of the 1970s and 1980s made us aware of the fact that we live on a spaceship with finite, that is, exhaustible resources. On the other hand, the energy crisis led to an overemphasis on all the issues concerning energy supply and all the problems connected with producing new energy. The energy crisis also led us to ignore strong evidence suggesting that water of appropriate quality to be used as a resouce will be used up more quickly than energy will. Although in principle water is a "renewable resource," the world's water reserves are diminishing in two fashions, the effects of which are multiplicative: enhanced consumption and accelerated degradation of quality.

Download or read book The Uses of Ecology written by W. T. Edmondson and published by University of Washington Press. This book was released on 2011-11-15 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: “ W. T. Edmondson has spent his career answering questions about the ecological impacts of human experiments on lakes in Washington State. In this volume, he recounts these studies and captures from his experiences a larger view of the nature of our environmental problems. . . . While the commentary is wide ranging, the foundation is a personal account of one ecologist’s lifetime experience on the dual points of research and public application of that research.”—Research and Exploration“W. T. Edmondson, a zoologist, extracts enduring lessons from his more than 50 years of experience in persuading political powers to make use of scientific knowledge when they set about drawing up laws for managing human interventions in the environment. Any scientist who follows in Edmondson’s footsteps should benefit from reading this sensitive recounting of political battles.”—Garrett Hardin, Pacific Northwest Quarterly
Download or read book Biodegradation and Persistence written by B. Beek and published by Springer. This book was released on 2005-09-06 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biodegradation is a key phenomen among environmental processes. Low degradation rates lead to the persistence of chemicals in the environment and, as a consequence, to delayed or long-term effects, which may be even unknown by now. In this volume the editor has pulled together the newest results of research in biodegradation and persistence of potential environmentally harmful substances and the complex process involved. The main focus is on the microbial degradation, the evolution and predictability of the respective pathways and their impact on bioremediation. Additional chapters deal with sewage treatment plants, the impact of toxicants on impaired biodegradation, and with the need of a more realistic view on fate and behaviour of chemicals in the environment.
Download or read book Scaling Relations in Experimental Ecology written by R. H. Gardner and published by Columbia University Press. This book was released on 2001 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the impact of recent advances in the theory of "scaling relationships" and identifies critical issues that must be considered if experimental results are used to understand the temporal and spatial scales of actual ecosystems. The complexity of ecosystems complicates experimental design. How, for example, does a scientist draw boundaries when studying species effects and interactions? Once these boundaries are drawn, how does one treat factors external to that study? Will the failure to consider external factors affect one's ability to extrapolate information across temporal and spatial scales? This volume provides a compilation from a broad range of ecologists with extensive experimental research experience that addresses these and other questions of scaling relations.
