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 Shallow Lakes 98 written by Norbert Walz and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume combines articles on shallow lakes from leading European scientists in limnology. It covers aspects of the dynamics of macrophytes, phytoplankton, zooplankton and benthos, nutrient loading, littoral-pelagic interactions, and sediment-water interactions, as well as lake management. The object was not to separate theory (e.g. modelling) and management in order to generate new theories for the understanding of shallow lake ecosystems. The volume provides a comprehensive overview of the ecology of shallow lakes, a lake type which differs in prominent ways from deeper lakes. The broad spectrum of issues may also reflect the spectrum of interested readers such as limnologists, water engineers, hydrobiologists, who will be informed on a high level about new developments.

This book was released on 2018-01-18 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the context of freshwater fisheries changing their strategies from the regulation of harvest and the enhancement of populations, to the creation and protection of habitats and the management of ecosystems, moves toward establishing an aquatic habitat classification system. Eight papers, from the February 1988 Symposium on the Classification and Inventory of Great Lakes Aquatic Habitats (the last in a series of Great Lakes Symposia), propose various classification approaches, most using a limited number of physical, chemical, and/or biological variables to produce some form of index. They also include overviews and summaries of the classification process.

This book was released on 2013 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: North temperate lakes are undergoing diverse physical, chemical, and biological changes, including warming water temperatures, shifts in lake trophic states, and introductions of non-native species. These ecosystem perturbations rarely occur in isolation, making it difficult to evaluate the impacts of concurrent perturbations on population and community dynamics. Here, I use Oneida Lake, New York, USA, to study interactions among multiple ecological changes and their combined effects on age-0 and juvenile yellow perch (Perca flavescens). These ecological changes included diversification of the predator and prey communities, shifts in lake trophic state from eutrophic to mesotrophic, and an expansion of littoral habitats. Multiple long-term limnological and fisheries datasets were integrated with short-term diet studies of age-0 yellow perch and their predators from nearshore and offshore habitats to develop a multi-habitat understanding of lake-wide responses to ecosystem perturbations. Walleye (Sander vitreus) were still the most important predator on age-0 and juvenile yellow perch, though the importance of alternative predators, such as white perch (Morone americana), smallmouth bass (Micropterus dolomieu), and largemouth bass (Micropterus salmoides), was also high and has likely increased. Consumption of age-0 yellow perch was dominated by walleye and white perch in offshore habitats during early summer, but transitioned to walleye, smallmouth bass, and largemouth bass in nearshore habitats during the fall and second year of life. As ecological conditions within the lake changed, age-0 yellow perch population dynamics became increasingly driven by littoral habitats and the population-level reliance on benthic energy pathways increased from 10-20% in the 1960s to 30-70% in the 2000s. These results illustrate the importance of both nearshore and offshore habitats to age-0 and juvenile yellow perch population dynamics and highlight the complexity of population- and community-level responses to ecosystem perturbations.

Download or read book Kansas Fishes written by Kansas Fishes Committee and published by University Press of Kansas. This book was released on 2014-07-15 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: A guide and a first-rate reference for the angler, scientist, and amateur naturalist alike, this comprehensive volume profiles each of the 144 fish species inhabiting the waterways of Kansas--as well as 27 others that might make their way to the state from nearby river basins. With 121 maps and 184 full-color drawings by Joseph Tomelleri, arguably the best illustrator of North American fishes, Kansas Fishes is an incomparable resource. For each species, the authors, an all-star cast of regional biologists, provide information about fundamental natural history, anatomy, and physiology, along with in-state distributions, habitats, characteristics, and pertinent issues of conservation and ecology. With these experts authoring detailed accounts of the species they know best, this is a uniquely authoritative account of the region's fishes. As such, it will prove useful to students and professionals while providing the passionate amateur and the simply curious an entry into the fascinating world of the fishes of Kansas and nearby states. The Kansas Fishes Committee members represent each of the six state universities (Emporia State, Fort Hays State, Kansas State, Pittsburg State, and Wichita State Universities, and the University of Kansas), as well as the Kansas Biological Survey, the Kansas Department of Health and Environment, and the Kansas Department of Wildlife, Parks and Tourism--the people responsible for studying, protecting, and educating people about the fishes and waters of Kansas. In addition to the committee, nearly 50 biologists from the United States and Canada volunteered to contribute species accounts to the book based on their expertise with those species in Kansas and nearby states. These individuals work for a variety of universities, federal and state agencies, and private companies, making this book a broad collaboration of experts on the fish species of Kansas.

Download or read book Centrarchid Fishes written by Steven Cooke and published by John Wiley & Sons. This book was released on 2009-09-08 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: Centrarchid fishes, also known as freshwater sunfishes, include such prominent species as the Largemouth Bass, Smallmouth Bass and Bluegill. They are endemic to Eastern North America where they form part of a multi-million dollar sports fishing industry, but they have also been widely introduced around the globe by recreational anglers, in aquaculture programs and by government fisheries agencies. Centrarchid Fishes provides comprehensive coverage of all major aspects of this ecologically and commercially important group of fishes. Coverage includes diversity, ecomorphology, phylogeny and genetics, hybridization, reproduction, early life history and recruitment, feeding and growth, ecology, migrations, bioenergetics, physiology, diseases, aquaculture, fisheries management and conservation. Chapters have been written by well-known and respected scientists and the whole has been drawn together by Professors Cooke and Philipp, themselves extremely well respected in the area of fisheries management and conservation. Centrarchid Fishes is an essential purchase for all fish biologists, ecologists, fisheries managers and fish farm personnel who work with centrarchid species across the globe.
