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.

Available in PDF, EPUB and Kindle. Book excerpt: The dipteran family Chironomidae is the most widely distributed and frequently the most abundant group of insects in freshwater, with rep resentatives in both terrestrial and marine environments. A very wide range of gradients of temperature, pH, oxygen concentration, salinity, current velocity, depth, productivity, altitude and latitude have been exploited, by at least some chironomid species, and in grossly polluted environments chironomids may be the only insects present. The ability to exist in such a wide range of conditions has been achieved largely by behavioural and physiological adaptations with relatively slight morphological changes. It has been estimated that the number of species world-wide may be as high as 15000. This high species diversity has been attributed to the antiquity of the family, relatively low vagility leading to isolation, and evolutionary plasticity. In many aquatic ecosystems the number of chironomid species present may account for at least 50% of the total macroinvertebrate species recorded. This species richness, wide distribution and tolerance to adverse conditions has meant that the group is frequently recorded in ecological studies but taxonomic difficulties have in the past prevented non-specialist identification beyond family or subfamily level. Recent works, including genetic studies, have meant that the family is receiving much more attention globally.

Book Synopsis The First International Lake Ladoga Symposium by : Heikki Simola
Download or read book The First International Lake Ladoga Symposium written by Heikki Simola and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Ladoga is the largest lake in Europe and, with its surface of 17,891 km2 and volume of 837 km3, it ranks among the top fifteen of the world's freshwater bodies. The ecological condition of Lake Ladoga is of concern to several million people living in its surroundings. There is evidence of water quality degradation and gradual eutrophication of the lake during the past decades; on the other hand, pollution control measures have improved the situation in many of the most polluted sites near industrial effluent sources. The first international Lake Ladoga Symposium was held in St. Petersburg on 22-26 November, 1993. The symposium was attended by 160 scientists, and about half of the papers presented at the symposium have been edited for this book. The contributions are grouped under the following headings: Present state of Lake Ladoga; Hydrodynamics of Lake Ladoga and other large water bodies; Water quality and pollution; Ecological studies of Lake Ladoga biota; History of Lake Ladoga and rates of change in its environment; Research methods for large lakes. Besides providing up-to-date information on the state of the lake, the papers deal with studies of many other large lakes of the cold-temperature zone and the general problems and methods of large lake research. Furthermore, the book is a valuable source of reference to the voluminous Russian limnological literature.

Book Synopsis Biological Monitoring of Aquatic Systems by : Stanford, L. Loeb
Download or read book Biological Monitoring of Aquatic Systems written by Stanford, L. Loeb and published by CRC Press. This book was released on 1994-01-24 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: With regional, national, and global processes affecting both the structure and function of lakes and rivers, assessment methodology must encompass many attributes to evaluate the impact of these processes on water quality. Many of the changes in biological communities correlate to resource exploitation, nonpoint pollutant interactions, and habitat alteration - factors that can be missed by routine chemical sampling. This creates the need for ecologically-based approaches to this problem. Biological monitoring is a fundamental part of an ecologically-based approach. Biological Monitoring of Aquatic Systems brings together contributions by authors recognized as leaders in the development and utilization of biological monitoring techniques for freshwater ecosystems. It provides a conceptual framework for the use of biological monitoring to assess the environmental health of freshwater resources. Biological monitoring is an important part of any water quality assessment program. Biological Monitoring of Aquatic Systems provides you with an understanding of water resources. It includes discussions concerning historical development, ecological basis, experimental design characteristics, case studies, and future concerns. As efforts to maintain and restore the world's water resources intensify, the need to develop accurate methods to assess the health of these resources becomes critical.
Book Synopsis Global Change in the Holocene by : John Birks
Download or read book Global Change in the Holocene written by John Birks and published by Routledge. This book was released on 2014-02-24 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Holocene spans the 11,500 years since the end of the last Ice Age and has been a period of major global environmental change. However the rate of change has accelerated during the last hundred years, due largely to human impacts and this has led to a growing concern for the future of our environmental resources. Global Change in the Holocene demonstrates how reconstructing the record of past environmental change can provide us with essential knowledge about how our environment works and presents the reader with an informed viewpoint from which to project realistic future scenarios. The book brings together key techniques that are widely used in Holocene research, such as radiocarbon dating, dendrochronology and sediment analysis and offers a comprehensive analysis of various archives of environmental change including instrumental and documentary records, corals, lake sediments, glaciers and ice cores. This reference will be an informative and cutting-edge resource for all researchers in the fields of climate change, environmental science, geography, palaeoecology and archaeology.

Download or read book Paleolimnology written by J. Meriläinen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Third International Symposium on Paleolimnology was held at the beginning of September 1981 in Finland. After registration at the University of 10ensuu and the opening session and welcome reception in the Town Hall, the participants moved to a hotel at Koli, a hill famed as a landmark and for its panoramic view. Here the lecture session, lasting four days, took place. Momentarily, the mosaic of the lakeland became visible between the clouds showing the hill slopes covered by mature spruce forest and scattered old birch trees, a reminder of the last slash-and-burn phase some 130 years ago. Altogether 120 paleolimnologists participated in the meetings and most also attended one of the two post-symposium excursions to the Arctic Circle and to South Finland. The lectures covered a wide range of paleolimnological subjects. The main topics, however, included current aspects in the dating of sediments and the history of eutrophication. The symposium was advised by the international organizing committee under the presidency of Professor Edward S. Deevey. Other members present at Koli were Dr. Maj-Britt Florin, Dr. Heikki Ignatius, Prof. Heinz Lamer, Prof. Gerbert Martinson and Dr. Magdalena Ralska-lasiewiczowa. They also gave direction to a discussion on future plans for international activity in paleolimnology. Later in the autumn, after the end of the symposium, the partici pants sent special thanks to the secretaries, Mrs. Eija Merilainen, Mrs. Tuula Nylander and Mrs. Anita Toukomaa, for solving individual problems during the symposium with smooth and rapid efficiency.

Book Synopsis Insects and Pollution by : K. Heliovaara
Download or read book Insects and Pollution written by K. Heliovaara and published by CRC Press. This book was released on 2018-02-01 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects and Pollution provides a comprehensive overview of both the direct and indirect effects of pollution on insects and discusses the ecological and economic consequences of these changes. The book reviews studies on pollutant-induced changes in insects classified according to their trophic position, taxonomy, and developmental stage. These changes are considered on different spatial and temporal scales, in different climatic and vegetation zones, and in different habitats (with emphasis on coniferous forests). The book also describes the effects of a variety of pollutants on terrestrial and aquatic ecosystems. Other topics considered include the effects of pollutants on insect physiology, ecology and evolution, and updating and synthesizing data. Insects and Pollution is the first book to combine entomological and ecotoxicological perspectives to address the far-ranging effects of pollution on insects. It is essential reading for entomologists, ecotoxicologists, conservation biologists, and other professionals in the environmental sciences.
Book Synopsis Biotic Response to Global Change by : Stephen J. Culver
Download or read book Biotic Response to Global Change written by Stephen J. Culver and published by Cambridge University Press. This book was released on 2006-12-14 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concern about the effects of global change on our planet's future has driven much research into the last few thousand years of earth history. In contrast, this volume takes a much longer viewpoint to provide a historical perspective to recent and future global change. Over 40 international specialists investigate the reaction of life to global environmental changes, from Cretaceous times to the turn of the century. During this time earth's climate has changed from a very warm, 'greenhouse' phase with no significant ice sheets to today's 'ice-house' world. A wide spectrum of animal, plant and protistan life is discussed, encompassing terrestrial, shallow-marine and deep-marine realms. Each chapter considers a particular taxonomic group, looking first at the general picture and then focusing on more specialized aspects such as extinctions, diversity and biogeography. This volume will form an invaluable reference for researchers and graduate students in paleontology, geology, biology, oceanography and climatology.
Book Synopsis Contaminated Sediments by : Ulrich Förstner
Download or read book Contaminated Sediments written by Ulrich Förstner and published by Springer. This book was released on 2006-04-10 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sediments are increasingly recognized as both a carrier and a possible source of contaminants in aquatic systems, and they may also affect groundwater quality and agricultural products when disposed on land. Four aspects are covered reflecting the development of knowledge in particle-associated pollutants during the past twenty-five years: - the identification, surveillance, monitoring and control of sources and distribution of pollutants, - the evaluation of solid/solution relations of contaminants in surface waters, - the study of in-situ processes and mechanisms of pollutant transfer in various compartments of the aquatic ecosystems, - the assessment of the environmental impact of particle-bound contaminants, i.e. the development of sediment quality criteria. A final chapter focusses on practical aspects concerning contaminated sediments.

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)
