The theme of the symposium was Shallow Lakes in a Changing World, and it dealt with water-quality issues, such as changes in lake limnology, especially those driven by eutrophication and pollution, increased nutrient loading and productivity, perennial blooms of cyanobacteria and loss of biodiversity.

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

Download or read book Structure and Function of World Shallow Lakes written by Mariana Meerhoff and published by Springer. This book was released on 2012-12-14 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on a selection of articles presented during the 6th International Shallow Lakes Congress, held in Punta del Este, Uruguay, in November 2008. Both the congress and the articles included in this volume raise a number of key issues. The expansion of research on shallow lakes around the world poses questions on the general validity of the theoretical framework developed in cool and cold temperate shallow lakes. In particular, comparisons along latitudinal gradients in Europe and America have shown that the functioning of lakes differs with the predominant climate and with their sensitivity to water level changes. This may have profound practical consequences for lake management and rehabilitation strategies. The results of controlled experiments and space-for-time (including latitudinal gradient) studies suggest that eutrophication symptoms likely become worse with an increase in mean temperature caused by climate warming. Consequently, the vulnerability of these ecosystems to external impacts such as changes in water level, arrival or introduction of exotic species, increase in nutrient loading and agrochemicals, will likely increase. It thus seems clear that nutrient inputs should be lowered to a much greater extent than previously thought in order to keep lakes’ diversity and conservation value, as well as to increase the chances of maintaining the still pristine lakes in a clear-water, high-biodiversity state.

Download or read book Large Asian Lakes in a Changing World written by Steffen Mischke and published by Springer Nature. This book was released on 2020-05-11 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describing the natural state of eight important lakes in Asia and the human impact on these lake ecosystems, this book offers a valuable reference guide. Over the past several decades the Aral Sea, Dead Sea, Lake Balkhash and other major lakes in Asia have undergone significant changes with regard to their size, water level, chemical composition, and flora and fauna. Most of these changes resulted from the loss of water from tributaries (now used for irrigation farming) or increasing consumption in local industries and households. However, significant human impacts may have begun as early as 2000 years ago. In addition to the three lakes mentioned above, Lake Sevan (Armenia), the Caspian Sea (Azerbaijan, Iran, Kazakhstan, Russia, Turkmenistan), Lake Issyk-Kul (Kyrgyzstan), and Lake Lop Nur (China) are discussed as the most prominent examples of changing lake ecosystems. In contrast, an example of an almost pristine lake ecosystem is included with the report on Lake Uvs Nuur (Mongolia). For each lake, the book summarizes its origin and early geological history, and reconstructs its natural state and variability on the basis of proxy records from drilled or exposed lake sediments that have accumulated since the last ice age. The frequently observed reductions in lake level and size during most recent decades led often to significant environmental impacts in the respective lake catchments including vegetation deterioration, soil erosion and badland formation, soil salinization or the formation of sinkholes.

This book was released on 2012-12-06 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the late 1970s. the adverse effects of man-made eutrophication became manifest in many countries. which explains. perhaps. why there was such a broad interest when the former Resources and Environment Area of the International Institute for Applied Systems Analysis (IIASA) organized a workshop on the subject. There was such an enthusiasm among the partici pants that two further workshops were quickly organized. one on deep and the other on shallow lake eutrophication problems. The organization of these meetings was extremely stimulating. and the round table discussions among scientists from both West and East remain thought provoking for those who took part. The general feeling emerged that the complexity and multifaceted nature of the problem, even though perhaps not fully recognized at that time. clearly demanded a systems analysis approach. No wonder. then. that the request made by the Hungarian Member Organization of nASA to adopt Lake Balaton as a "real life laboratory" for an nASA case study fell on fertile ground. the more so since it appeared that shallow lake eutrophication had received less attention and was less well understood than that of deep lakes. And so the nASA Lake Balaton Case Study began. with the appointment of Gerrit van Straten as the first leader of the project.

Download or read book Managing Wildlife in a Changing World written by Jafari R. Kideghesho and published by BoD – Books on Demand. This book was released on 2021-12-08 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The declining trends of wildlife habitats and species populations are obvious consequences of the socio-economic, political, ecological, and technological changes occurring globally. Along with human population growth, there is a growing wave of wildlife diseases, invasive alien species, human-wildlife conflicts, climate change, poaching, infrastructure development, and economic options that are ecologically damaging. These changes have implications on the management of wildlife resources. Managing Wildlife in a Changing World draws experiences from different parts of the world on status, challenges, and efforts of reversing the current negative trends on wildlife habitats and species in the face of these changes. This book is useful for academicians, researchers, policy makers, conservation practitioners, students, and other interested readers.

Download or read book Eco Hydrodynamic Modelling of Primary Production in Coastal Waters and Lakes Using BLOOM written by F.J. Los and published by IOS Press. This book was released on 2009-03-03 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many areas nutrient loadings to aquatic ecosystems have increased considerably as a result of population growth, industrial development and urbanisation. This has resulted in enhanced growth of phytoplankton, shifts in composition of the plankton community and changes in the structure of ecosystems, which are often considered to be objectionable. To help understanding these processes and to predict future conditions, a mathematical model, BLOOM, has been developed and applied since 1977. It simulates the biomass and composition of phytoplankton and macro algae in relation to the amount of nutrients, the under water light climate and grazing. It can be applied as a relatively simple screening tool, but also as part of advanced integrated modelling systems including additional hydrodynamic, suspended matter and habitat components. The model has been extensively validated, which means that its credibility was demonstrated systematically for certain types of applications. It has been applied as a supporting management tool to a very large number of aquatic systems worldwide: lakes, channel systems, estuaries, lagoons and coastal seas, using generic coefficients (one set for fresh water, one set for marine simulations) as much as possible. The principles of the model, its validation and a number of representative applications are described in Eco-Hydrodynamic Modelling of Primary Production in Coastal Waters and Lakes Using BLOOM.

Available in PDF, EPUB and Kindle. Book excerpt: The third in Sven Hedin's Central Asia trilogy, The Wandering Lake is arguably his most famous work and a rare account of a now-vanished world. The lake of Lop Nur, the 'heart of the heart of Asia', is one of the world's strangest phenomena. Situated in the wild Chinese province of Xinjiang, Lop Nur - 'the wandering lake'- has for millennia been in a perpetual state of flux, drifting north to south, often tens of kilometres in as many years. It was once the lifeblood of the great Silk Road kingdom of Loulan, which flourished in this otherwise barren region 2,000 years ago, and its peculiar movements confused even Ptolemy, who marked the lake twice on his map of Asia. Following 'the pulse-beats of Lop Nur as a doctor examines a patient's heart', Sven Hedin became captivated by its peripatetic movements and for forty years his destiny was inextricably linked with that of this mysterious lake and the region surrounding it. His last journey to Lop Nur was in 1934, just days after he was released as a prisoner of General Ma Chung-yin (the rebel leader of Xinjiang). Travelling the length of the Konche-daria and Kum-daria rivers by canoe, Hedin embarked on his last Central Asian expedition and proved what he had always suspected - that Lop Nur did indeed shift position - and why. When he camped on its vast banks at night, Lop Nur was deep and full. Today, this once great lake - a mighty reservoir in the desert - is nothing but windblown sand and salty marsh. A gripping story of adventure and discovery, The Wandering Lake is a masterpiece by one of history's last great explorers.

Download or read book Shallow Lakes 98 written by Norbert Walz and published by Springer. This book was released on 2011-01-28 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume combines articles on shallow lakes from leading European scientists in limnology. It covers aspects of the dynamics of macrophytes, phytoplankton, zooplankton and benthos, nutrient loading, littoral-pelagic interactions, and sediment-water interactions, as well as lake management. The object was not to separate theory (e.g. modelling) and management in order to generate new theories for the understanding of shallow lake ecosystems. The volume provides a comprehensive overview of the ecology of shallow lakes, a lake type which differs in prominent ways from deeper lakes. The broad spectrum of issues may also reflect the spectrum of interested readers such as limnologists, water engineers, hydrobiologists, who will be informed on a high level about new developments.

Download or read book Ecology of Freshwaters written by Brian R. Moss and published by John Wiley & Sons. This book was released on 2018-06-11 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: The new edition of this established textbook, now with full colour illustration, has been extensively revised and continues to provide a comprehensive, stimulating, readable and authoritative coverage of freshwater habitats, their communities and their functioning, the world over. The work will be of great value to undergraduate and graduate students, fellow researchers and water managers, and the plain language and lack of jargon should make it accessible to anyone interested in the functioning and current state of lakes and rivers. Having taught and researched over fifty years and six continents, Professor Brian Moss makes here extensive use of his personal experience as well as the huge literature now available on freshwaters. This is the fifth edition of his textbook, which, since the first edition in 1980, has steadily evolved to reflect a rapidly changing science and environment. It places increasing emphasis on the role of people in damaging and managing freshwaters as we move into the Anthropocene epoch and face unprecedented levels of climate and other changes, whilst rejoicing in the fascination of what are left of near pristine freshwater ecosystems. Professor Moss retired from the University of Liverpool following a career in Africa, the USA and the UK. He was awarded medals by the International Society for Limnology, of which he was President from 2007 to 2013, and The Institute of Ecology and Environmental Management. He was given The Ecology Institute's Excellence in Ecology Prize in 2009 and the book written for that prize, Liberation Ecology, was awarded the British Ecological Society's best ecology book prize in 2013.

Download or read book Water for Food in a Changing World written by Alberto Garrido and published by Routledge. This book was released on 2011-04-12 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is not enough water globally for all the things humans need and want water to do for us. Water supply bubbles are bursting in China, the Middle East and India with potentially serious implications for the global economy and for political stability. Even the United States is depleting groundwater on average 25% faster than it is being replenished. Our thirst for water grows with our population, but the amount of fresh water available on Earth is fixed. If we assume "business as usual" by 2050 about 40% of the projected global population of 9.4 billion is expected to be facing water stress or scarcity. With increasing climate variability being predicted by global climate models, we are likely also to have more people without adequate water more of the time, even in water-rich regions. Irrigation productivity rose dramatically over the past 40 years as a result of the Green Revolution. However, even if we disregard the environmental impacts caused by that revolution, we are no nearer to achieving global food security than we were 40 years ago, as every time we come close to filling the food production gap population growth and ecosystem decline associated with water diversions to human purposes set us back. Our natural and agricultural ecosystems are trying to tell us something. This book pursues these overarching themes connecting to water and food production at global and regional scales. The collection offers a comprehensive discussion of all relevant issues, and offers a wide-ranging discussion with the aim of contributing to the global debate about water and food crises.
