This book was released on 2019-01-09 with total page 407 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.

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 It also contains several unpublished records dating from 1958.

Available in PDF, EPUB and Kindle. Book excerpt: Long-term population monitoring is an important tool in our investigations of the role waterbirds play in their environment. This book is international in scope and presents information on species as diverse as the Common Loon, Harlequin Duck, and Semi-Palmated Sandpiper, and habitat in locations ranging from Iceland to Japan. Papers presented in this volume further our understanding of the important role that limnology plays in determining habitat suitability for waterbirds.

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
