This book was released on 2018-10-05 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: Certain types of pesticides are widely used in agriculture in all parts of the world due to their relatively low cost, broad spectrum of activity, and high efficiency. These pollutants contaminate not only the surrounding soils and water but, in many cases, also enter into the drinking water. The Handbook of Research on the Adverse Effects of Pesticide Pollution in Aquatic Ecosystems provides emerging research exploring the theoretical and practical aspects of the prevention of accumulation of toxic pollutants such as agrochemicals and organochlorine pesticides in aquatic ecosystems and applications within ecology and agriculture. Featuring coverage on a broad range of topics such as pesticide monitoring, metabolites, and risk assessment, this book is ideally designed for scientists, researchers, engineers, policymakers, agricultural specialists, industrialists, academicians, and students seeking current research on the risks of water contaminants in small ecosystems.

Download or read book Biology and Management of Coregonid Fishes 2005 written by Małgorzata Jankun and published by . This book was released on 2007 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coregonids (whitefish, vendace, cisco, etc.) are cold-water adapted fishes common throughout the Holarctic in North America, Europe and Asia. They have evolved into a myriad of forms, subspecies and species during and after the Pleistocene glaciations. They are therefore rich subjects for the study of evolutionary problems. Coregonids support important commercial, subsistence and recreational fisheries and are the subject of significant aquaculture operations around the world. Although coregonids are generally considered to be fairly adaptable to the pressures of exploitation, they do appear to be sensitive to changing environmental conditions such as eutrophication and a number of populations and species have been extirpated, usually by deteriorating environments coupled with the introduction of exotic species and by commercial exploitation. This sizeable volume contains 40 peer-reviewed contributions on current topics of coregonid research presented at the Ninth International Symposium on the Biology and Management of Coregonid Fishes, held in August 2005, in Olsztyn, Poland. They cover all aspects of coregonid life and managment. The contributions can be grouped into of five subject areas: genetics and evolution; biology, life history and population dynamics; invasive species; fisheries in Europe and fisheries in North America
Download or read book Taxonomic Studies of the Subgenus Amphora Cleve of the Genus Amphora Bacillariophyceae in Japan written by Tamotsu Nagumo and published by . This book was released on 2003 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genus Amphora is one of the larger genera belonging to the family Naviculaceae and includes about 350 taxa. It is a widespread genus with a few species occurring in freshwater and brackish water, and many species in marine habitats. Members of the genus are clearly distinguished from related genera. The characteristic, strongly dorsiventral frustule has raphe systems which lie close to the ventral margins of the valve. There is no taxonomic revision and clear definition of the genus Amphora based modern taxonomic criteria covering both freshwater to marine species. This study deal with the taxonomy the subgenus Amphora, for freshwater and marine species in Japan. In addition to the characters observable by light microscopy, characters revealed mainly by scanning and transmission electron microscopy, such as raphe system and the shape of dorsal marginal costa, were employed to establish the taxonomy of the taxa considerd herein. Eighteen taxa are recognized in this work. First, each taxon was observed in detail using SEM to expand current knowledge of its fine structure. Taxonomic identification was then confirmed with reference to type material or other historic collections. Among the taxa investigated here, four are new to science, one is a new combination and one is a new name. Ten of the taxa investigated here (Amphora barrowiana (Patr. et Freese) Nagumo comb. nov., A. copulata (Kützing) Schoeman et Archibald, A. hiromuii Nagumo sp. nov., A. inariensis Krammer, A. liriope Nagumo sp. nov., A. macedoniensis Nagumo sp. nov., A. ovalis Kützing., A. pediculus (Kützing) Grun., A. rotunda Skv., A. sibirica Skv. et Meyer) are from freshwaters habitats. Three (A. arenicola (Grun.) Cleve, A. javanica Schmidt, A. libyca Ehr.) are from brackish-water habitats and five (A. gigantea Grun., A. immarginata Nagumo sp. nov., A. marina W. Smith, A. plativalvata Nagumo nom. et stat. nov., A. schmidtii Grun.) are from marine habitats.

Available in PDF, EPUB and Kindle. Book excerpt: The biological sciences cover a broad array of literature types, from younger fields like molecular biology with its reliance on recent journal articles, genomic databases, and protocol manuals to classic fields such as taxonomy with its scattered literature found in monographs and journals from the past three centuries. Using the Biological Literature: A Practical Guide, Fourth Edition is an annotated guide to selected resources in the biological sciences, presenting a wide-ranging list of important sources. This completely revised edition contains numerous new resources and descriptions of all entries including textbooks. The guide emphasizes current materials in the English language and includes retrospective references for historical perspective and to provide access to the taxonomic literature. It covers both print and electronic resources including monographs, journals, databases, indexes and abstracting tools, websites, and associations—providing users with listings of authoritative informational resources of both classical and recently published works. With chapters devoted to each of the main fields in the basic biological sciences, this book offers a guide to the best and most up-to-date resources in biology. It is appropriate for anyone interested in searching the biological literature, from undergraduate students to faculty, researchers, and librarians. The guide includes a supplementary website dedicated to keeping URLs of electronic and web-based resources up to date, a popular feature continued from the third edition.

Download or read book River Futures written by Gary J. Brierley and published by Island Press. This book was released on 2012-09-26 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Across much of the industrialized world, rivers that were physically transformed and ecologically ruined to facilitate industrial and agricultural development are now the focus of restoration and rehabilitation efforts. River Futures discusses the emergence of this new era of river repair and documents a comprehensive biophysical framework for river science and management. The book considers what can be done to maximize prospects for improving river health while maintaining or enhancing the provision of ecosystem services over the next fifty to one-hundred years. It provides a holistic overview of considerations that underpin the use of science in river management, emphasizing cross-disciplinary understanding that builds on a landscape template. The book frames the development of integrative river science and its application to river rehabilitation programs develops a coherent set of guiding principles with which to approach integrative river science considers the application of cross-disciplinary thinking in river rehabilitation experiences from around the world examines the crossover between science and management, outlining issues that must be addressed to promote healthier river futures Case studies explore practical applications in different parts of the world, highlighting approaches to the use of integrative river science, measures of success, and steps that could be taken to improve performance in future efforts. River Futures offers a positive, practical, and constructive focus that directly addresses the major challenge of a new era of river conservation and rehabilitation—that of bringing together the diverse and typically discipline-bound sets of knowledge and practices that are involved in repairing rivers. It is a valuable resource for anyone involved in river restoration and management, including restorationists, scientists, managers, and policymakers, as well as undergraduate and graduate students.
