Download or read book The Diatoms written by John P. Smol and published by Cambridge University Press. This book was released on 2010-09-30 with total page 687 pages. Available in PDF, EPUB and Kindle. Book excerpt: This much revised and expanded edition provides a valuable and detailed summary of the many uses of diatoms in a wide range of applications in the environmental and earth sciences. Particular emphasis is placed on the use of diatoms in analysing ecological problems related to climate change, acidification, eutrophication, and other pollution issues. The chapters are divided into sections for easy reference, with separate sections covering indicators in different aquatic environments. A final section explores diatom use in other fields of study such as forensics, oil and gas exploration, nanotechnology, and archaeology. Sixteen new chapters have been added since the first edition, including introductory chapters on diatom biology and the numerical approaches used by diatomists. The extensive glossary has also been expanded and now includes over 1,000 detailed entries, which will help non-specialists to use the book effectively.
Download or read book Paleolimnology written by Andrew S. Cohen and published by Oxford University Press. This book was released on 2003-05-29 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text, written by a leading researcher in the field, describes the origin and formation of lakes in order to give context to the question of how lacustrine deposits form. It explains the process of sedimentation in lakes and the chemistry of those deposits and describes how the age of lake deposits are determined. Additionally, this book shows how different groups of fossils are used in interpreting the paleontological record of lakes. In order to illustrate the more synthetic approaches to interpreting the history of lakes, the author also discusses such special topics as lake-level history, lake evolution, and the impact of environmental change on lakes.

Download or read book The Peace Athabasca Delta written by Kevin P. Timoney and published by University of Alberta. This book was released on 2013-09-15 with total page 610 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In the delta, water is boss, change is the only constant, and creation and destruction exist side by side." The Peace-Athabasca Delta in northern Alberta is a globally significant wetland that lies within one of the largest unfragmented landscapes in North America. Arguably the world's largest boreal inland delta, it is renowned for its biological productivity and is a central feature of a UNESCO World Heritage Site. Yet the delta and its indigenous cultures lie downstream of Alberta's bitumen sands, whose exploitation comprises one of the largest industrial projects in the world. Kevin Timoney provides an authoritative synthesis of the science and history of the delta, describing its ecology, unraveling its millennia-long history, and addressing its uncertain future. Scientists, students, leaders in the energy sector, government officials and policy makers, and conscientious citizens everywhere should read this lively work.

Download or read book Breaking the Ice Briser la Glace written by Association of Canadian Universities for Northern Studies and published by Canadian Circumpolar Institute. This book was released on 2004 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Topics range from fossil remnants on Axel Heiberg Island to collaborative tourism planning in the Yukon; from the influence of sea-ice and ocean circulation on arctic climate, to the differences between Inuit healing and western medicine. Yet, there is a common thread that links all of these papers. It is a place. It is the North. The importance of such a perspective is often lost in an academic world that rewards specialization by emphasizing expertise in a narrow field. But the boundaries between disciplines are becoming more and more artificial in an increasingly complex and interconnected world. An interdisciplinary approach built on 'place' provided a platform from which researchers could transcend these boundaries. The ACUNS conference, and by extension, these proceedings, helps 'break the ice'. Includes papers by Marni Amirault, Donna L. Atkinson, Johanna Bergé, Nilgun Cetin, Paul G. Myers, Suzanne de la Barre, Vasiliki Douglas, Audrey R. Giles, Sarah Giles, Brenda Guernsey, Joanna Kafarowski, Gita J. Laidler, Francis Levesque, Patrick T. Maher, Andrew C. L. Postnikoff, James F.

Download or read book Restoration of Aquatic Ecosystems written by National Research Council and published by National Academies Press. This book was released on 1992-01-01 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Available in PDF, EPUB and Kindle. Book excerpt: Now in its second edition, Pollution of Lakes and Rivers provides essential insights into present-day water quality problems from an international perspective. Explains simply and effectively how lake sediments can be used to reconstruct pollution history Includes over 200 additional references and a new chapter on recent climatic change and its effects on water quality and quantity Tackles present-day water quality problems from an international perspective Previously published by Hodder Arnold PowerPoint slides of the artwork from the book are available from: http://post.queensu.ca/~pearl/textbook.htm Reviews: "This is a very well-written and wide-ranging volume that is both instructive and topical. It is likely to prove useful as an introduction to the general area, a reference source and for teaching purposes." (The Holocene, November 2008) "If you thought that paleolimnology was just mud, pollen, and diatoms then you will likely be both struck by the complexity of this field of research and grateful that John Smol, FRSC, has described it so clearly and broadly. Simply put, the second edition is an excellent book." ( Journal of Phycology, 2008) “This is a useful text. It provides a good level of detail so that the beginner in this area can appreciate what palaeolimnology can (and cannot) achieve. It goes beyond the simple introduction to provide a detailed understanding of how techniques can be applied ... This is a different take on the usual pollution text and would be of great use to those wishing to understand more from sedimentary records.” Taken from the British Ecological Society’s Teaching Ecology website "John Smol has extensive experience in this field of paleoenvironmental research which he combines well with his excellent written communication skills to produce a text that is easy to read but also thought provoking." (Quaternary Science Reviews, 2009) “The breadth of coverage in this text is impressive.” (Lake and Reservoir Management, 2009) “If I could speak with fluidity and clarity in my lectures as consistently as John Smol writes my students would be very grateful.” (Journal of Paleolimnology, 2009)
