Book excerpt: Biology and Control of Aquatic Plants: A Best Management Practices Handbook is the fourth edition of a handbook produced by the not for profit Aquatic Ecosystem Restoration Foundation (AERF). The mission of the AERF is to support research and development which provides strategies and techniques for the environmentally and scientifically sound management, conservation and restoration of aquatic ecosystems. One way the Foundation accomplishes this mission is by producing this handbook to provide information to the public regarding the benefits of aquatic ecosystem conservation and aquatic plant management. The first, second and third editions of this handbook became some of the most widely consulted references in the aquatic plant management community. This fourth edition has been specifically designed with water resource managers, water management associations, homeowners and customers and operators of aquatic plant management companies and districts in mind. Our goal in preparing this handbook is to provide basic, scientifically sound information to assist decision-makers with their water management questions.

Download or read book Quaternary Glaciation of the Great Lakes Region written by Alan Kehew and published by Geological Society of America. This book was released on 2018 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Taking advantage of new technological advances in Quaternary geology and geomorphology, this volume showcases new developments in glacial geology. Honoring the legacy of Frank Leverett and F.B. Taylor's 1915 USGS monograph of the region, this book includes 12 chapters that cover diverse topics ranging from hydrogeology, near-surface geophysics, geotectonics, and vertebrate paleontology to glacial geomorphology and glacial history. Several papers make use of detailed but nuanced shaded relief maps of digital elevation models of LiDAR data; these advances are brought into historical perspective by visiting the history of geologic mapping of Michigan. Looking forward, interpretations of the shaded relief maps evoke novel processes, such as regional evolution of subglacial and supraglacial drainage systems of receding glacial margins. The volume also includes assessment of chronological issues in light of greater accuracy and precision of radiocarbon dating of plant fossils using accelerator mass spectrometry versus older techniques.

Download or read book A Handbook of Global Freshwater Invasive Species written by Robert A. Francis and published by Routledge. This book was released on 2017-08-11 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

Download or read book Water Quality: Monitoring and Assessment written by Stephanie Fraser and published by . This book was released on 2020-09-08 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: The biological, radiological, chemical and physical traits of water are known as water quality. It is a measure of the water condition related to the requirements of biotic species and to human need. The health of ecosystems, safety of human contact, and drinking water are the most common standards used to measure water quality. Water quality parameters can be categorized into human consumption, environmental water quality, and industrial and domestic use. The measurement of water quality includes the process of sample collection, chemical analysis, real-time monitoring and testing in response to natural disasters. Various environmental indicators such as physical, chemical and biological indicators are also observed and used for the monitoring of water quality. This book explores all the important aspects of water quality in the present day scenario. It elucidates new techniques and their applications in a multidisciplinary manner. It will prove to be immensely beneficial to students and researchers in this field.

Download or read book A Canoe Voyage Up the Minnay Sotor written by George William Featherstonhaugh and published by St. Paul : Minnesota Historical Society. This book was released on 1970 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: This detailed travelogue, the concluding part of a two-volume work written primarily for a British readership, discusses the United States' geological resources and offers critical observations about the manners and customs of its different peoples. It was written over a decade after the author explored St. Peter's River--the "Minnay Sotor" of the book's title--in 1835, and draws upon the journals he kept along the way. A Canoe Voyage (volume 2) deals with Featherstonhaugh's return journey to the east coast. His route, interrupted by many detours and excursions through what is now the state of Wisconsin, took him from Fort Snelling and Galena to St. Louis and its environs. Traveling by steamer along the Mississippi and Ohio Rivers to Paducah, Kentucky, Featherstonhaugh then journeyed down the Tennessee River to Tuscumbia, where he caught a train to Decatur. From this point, he journeyed by steamer, stage, and dugout canoe, to areas described as "Cherokee country," then onward to Georgia, the Carolinas,Virginia, and Washington, D.C, his ultimate destination. In this volume, Featherstonhaugh inveighs against fraudulent land speculators, slavery, the treatment of the Cherokee, and the bad manners of fellow travelers. He found much to admire in the beauty of the Southern Appalachians and the hospitality of John C. Calhoun, the celebrated Southern statesman.
