Download or read book The Alte Donau Successful Restoration and Sustainable Management written by Martin T. Dokulil and published by Springer. This book was released on 2019-01-09 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here we report on a 25-year long-term sequence of measures to return a deteriorated recreational urban lake, Alte Donau in Vienna to acceptable water quality. Metropolitan waters require focused ecosystem management plans and intensive in-lake efforts. We explored physico-chemical conditions, food web from viruses to fish and water birds, the sediments, the littoral zone and the catchment, management and urban planning, and global warming. Several restoration techniques were tested and critically evaluated. The final management plan was based on bi-stable theory. During the recovery phase, numerous surplus adjustments had to be implemented to secure sustainable achievement.
Download or read book A Complete Guide to the Birds of Malta written by Natalino Fenech and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lying in the centre of the Mediterranean, Malta is a natural staging post for migrant birds crossing from Africa to Europe in spring as well as for migrants returning from their breeding grounds in Europe to the African continent in autumn. Birds have attracted man's attention for a long time and this book shows images of birds in prehistory, art, stamps, coins, antique embroidery and so forth. It also speaks about birds in all aspects of Maltese culture, from folklore to language. It is also a photographic record of many of the birds that regularly visit the islands and features ones that are rare or have been recorded a handful of times. It also contains several unpublished records dating from 1958.

Download or read book Ecology of Shallow Lakes written by Marten Scheffer and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecology of Shallow Lakes brings together current understanding of the mechanisms that drive the diametrically opposite states of water clarity, shown by the cover paintings, found in many shallow lakes and ponds. It gives an outline of the knowledge gained from field observations, experimental work, and restoration studies, linked by a solid theoretical framework. The book focuses on shallow lakes, but the lucid treatment of plankton dynamics, resuspension, light climate and the role of vegetation is relevant to a much wider range of aquatic systems. The models that are used remain simple and most analyses are graphical rather than algebraic. The text will therefore appeal to students, scientists and policy makers in the field of ecology, fisheries, pollution studies and water management, and also to theoreticans who will benefit from the many real-world examples of topics such as predation and competition theory, bifurcation analysis and catastrophe theory. Perhaps most importantly, the book is a remarkable example of how large field experiments and simple models can catalyze our insight into complex ecosystems. Marten Scheffer wrote this book while at the Institute of Inland Water Management and Waste Treatment, RIZA, Lelystad, The Netherlands. He is currently at the Department of Water Quality Management and Aquatic Ecology of the Wageningen Agricultural University. Reviews `Much rarer are textbooks that so succinctly sum up the state-of-the-art knowledge about a subject that they become instant `bibles'. This book is one of these. It is probably one of the best biological textbooks I have read. Scheffer masterfully pulls all this information together under one cover and presents a coherent account, which will serve as a benchmark for the subject. The reader will not gain any great insight into the breeding biology of pike from this book, nor learn much about dragonflies or newts. They will, however, come to understand the essential nature of shallow lakes or, as the author puts it, `how shallow lakes work'. Overall, this book will be of great interest to practical and theoretical ecologists, students and managers in all fields of biology. All freshwater ecologists should certainly read it.' Simon Harrison in Journal of Ecology, 86 `The book by Scheffer can be seen as a milestone in the recognition of shallow lakes as a research topic in its own right. Scheffer uses three approaches concurrently to unravel the functioning of shallow lakes: 1) statistical analysis of large datasets from a variety of lakes; 2) simple abstract models made up of a few non-linear ordinary differential equations, which he calls `mini-models'; and 3) logical reasoning based on a mixture of results from fieldwork, experiments and models. What is new is that Scheffer links mathematics very nicely with what one feels is a correct description of the functioning of a shallow lake. Employing logical reasoning, Scheffer combines all these sources of knowledge into a general, coherent picture of the functioning of a shallow lake.' Wolf Mooij in Aquatic Ecology, 32

Available in PDF, EPUB and Kindle. Book excerpt: Part of the problem in dealing with public perceptions about Chesapeake Bay is that people think it will last forever. This obviously is not true. As oceanographer Jerry Schubel has noted, twenty thousand years ago there was no Chesapeake Bay. Since that time, there have been other beginnings and endings of other Chesapeake Bays. As we look to the future, however, we can see that increasingly the transformation of the Chesapeake will be more a human phenomenon than a work of nature.
Download or read book Maximum Power written by Howard Thomas Odum and published by . This book was released on 1995 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maximum Power is a synthesis of the creative genius of Howard Thomas Odum as seen through his own words and those of his students, many of whom are now applying his ideas to the world in diverse ways. Offering the holistic, system-oriented thinking of Odum, this in-depth volume examines the interrelationship of humans and nature by integrating environment, energy, and economics. Maximum Power traces the development of Odum's ideas with the objective of providing the conceptual and research history that has led to Odum's far-reaching ideas about making social decisions. The volume is organized along the chronological path that Odum himself followed, from ecology to ecological engineering to ecological economics to his controversial synthesis called "emergy analysis." The writings of fifty scientists from a wide range of disciplines are grouped into five sections: The Contributions of H.T. Odum to Subdisciplines of Ecology, Environmental Management and Engineering, H.T. Odum and Economics, Education, and Personal Memoirs.

Download or read book Closed Sea written by Kent Mountford and published by . This book was released on 2002 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Closed Sea weaves together a colorful history of whalers and pirates, Revolutionary patriots and loyalists, fishermen and loggers, iron masters and life saving crews, sportsmen and holiday makers. Filled with historical anecdote and keen observations of sea and shore, it is a compelling portrait of the Barnegat Bay region and its history. With a naturalist's eye and a sailor's experience, environmental historian Kent Mountford opens our eyes to the Shore's past, its shifting inlets, disappearing islands, dangerous tides and shoals. Moving inland, he documents the Pinelands environment and the industries it has supported over the centuries. Closed Sea tells the remarkable history of a fascinating place, a place of great beauty, danger and opportunity, a place that has cast its spell on generations of people. This book is published with support, in part, from the Ocean County Historical Society, the Barnegat Bay Estuary Program, and the Tuckerton Seaport.
Download or read book Mudflat Ecology written by Peter G. Beninger and published by Springer. This book was released on 2019-02-13 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intertidal mudflats are distinct, highly-productive marine habitats which provide important ecosystem services to the land-sea interface. In contrast to other marine habitats, and despite a large body of primary scientific literature, no comprehensive synthesis exists, such that the scattered knowledge base lacks an integrated conceptual framework. We attempt to provide this synthesis by pulling together and contextualizing the different disciplines, tools, and approaches used in the study of intertidal mudflats. The editor pays particular attention to relationships between the various components of the synthesis, both at the conceptual and the operational levels, validating these relationships through close interaction with the various authors.

This book was released on 1995 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report reviews the available information on the use, environmental fate, and toxicity of spent lead shot and lost lead fishing weights. The report begins with a summary of information on the production, import, and use of lead shot and fishing sinkers in Canada. It then discusses the fate of these products in the environment, including chemical transformation of metallic lead in the environment, lead concentrations in soils and biota, and factors affecting the environmental mobility of lead compounds. The next section assesses the toxicity of lead shot and sinkers to waterfowl and non-waterfowl species, effects of lead shot ingestion in cattle, and human health concerns about hunting with lead shot. The report ends with a discussion of options for managing the negative impacts of those products, including using alternatives to lead, restricting use of lead shot, and alternative fishing sinker products.
