Sudbury, Ontario is one of the world's most polluted areas. A century of industrial activities has resulted in thousands of acidified lakes and vast areas of denuded land. This book describes, in a manner accessible to a wide audience, the damage and the efforts at environmental restoration at Sudbury which resulted in its winning a United Nations award in 1992 for land reclamation. The book has been written by a distinguished group of contributors, ranging from experts in acid rain and land reclamation to environmental engineers and toxicologists.

Coastal Wetlands, Second Edition: An Integrated and Ecosystem Approach provides an understanding of the functioning of coastal ecosystems and the ecological services that they provide. As coastal wetlands are under a great deal of pressure from the dual forces of rising sea levels and the intervention of human populations, both along the estuary and in the river catchment, this book covers important issues, such as the destruction or degradation of wetlands from land reclamation and infrastructures, impacts from the discharge of pollutants, changes in river flows and sediment supplies, land clearing, and dam operations. - Covers climate change and its influence on coastal wetland form and function - Provides a fully updated and expanded resource, including new chapters on modeling, management and the impact of climate change - Contains full-color figures of wetlands and estuaries in different parts of the world

The arctic region is predicted to experience the earliest and most pronounced global warming response to human-induced climatic change. This book synthesizes information on the physiological ecology of arctic plants, discusses how physiological processes influence ecosystem processes, and explores how climate warming will affect arctic plants, plant communities, and ecosystem processes. - Reviews the physiological ecology of arctic plants - Explores biotic controls over community and ecosystems processes - Provides physiological bases for predicting how the Arctic will respond to global climate change

R.E. Newell President, International Commission on Climate International Association of Meteorology and Atmospheric Physics Water is the active ingredient in the global climatic system, its physical properties ensuring that it plays a major role. Its high thermal capacity provides a mechanism for moderating mid latitude winter temperatures; solar energy is absorbed by the surface layers of the middle latitude oceans in summer and is released to the atmosphere in winter as the ocean cools. The variation of saturation vapour pressure with temperature is the factor which causes oceanic surface temperatures at low latitudes to be limited by evaporation to values near 29°C, thereby limiting tropical marine air temperatures to about the same value. The substantial amount of energy involved in phase changes - the latent heat - governs the passage of solar energy to the atmo sphere; visible solar radiation is absorbed at the Earth's surface, energy is supplied to evaporate water and the latent heat is released to the atmosphere when and where condensation occurs, which is often a considerable distance from the source of the moisture. The infrared radiative characteristics of water vapour, namely the broad vibration-rotation bands typical of a triatomic molecule, permit it to act as the principal agent of energy loss from the atmosphere, throu?,h infrared radiation to space.

Although, as W.D. Billings notes in his chapter in this book. the development of physiological ecology can be traced back to the very beginnings of the study of ecology it is clear that the modern development of this field in North America is due in the large part to the efforts of Billings alone. The foundation that Billings laid in the late 1950s came from his own studies on deserts and subsequently arctic and alpine plants, and also from his enormous success in instilling enthusiasm for the field in the numerous students attracted to the plant ecology program at Duke University. Billings' own studies provided the model for subsequent work in this field. Physiological techniques. normally confined to the laboratory. were brought into the field to examine processes under natural environmental conditions. These field studies were accompanied by experiments under controlled conditions where the relative impact of various factors could be assessed and further where genetic as opposed to environmental influences could be separated. This blending of field and laboratory approaches promoted the design of experiments which were of direct relevance to understanding the distribution and abundance of plants in nature. Physiological mechanisms were studied and assessed in the context of the functioning of plants under natural conditions rather than as an end in itself.

The Proceedings of the Seventh International Rotifer Symposium, Rotifera VII, spans subjects from community ecology through biochemistry, from the most basic science through the most clearly applied technology. Some papers report exceptional progress in our knowledge of rotifer anatomy and biochemistry, as well as rotifer molecular biology, evolution and life histories. The book also contains an interesting article describing a hundred years of Polish contributions to rotiferology as well as papers discussing both general patterns of rotifer biogeography and rotifer distribution in different habitats, together with many aspects of the ecology of rotifer species, populations and communities. Audience: This update on rotifer taxonomy, biology and ecology will be of great interest to zoologists, especially hydrobiologists studying the structure and function of freshwater zooplankton.

Bill Streever, author of Bringing Back the Wetlands and numerous technical articles about wetland restoration and creation, worked for two years to bring together this collection of papers. Authors ranging from private landowners to government managers to scientists present regional overviews, case studies, and discussions of various issues. Regional overviews cover areas as small as the Commonwealth of the Northern Mariana Islands to areas as large as Australia and Africa. Case studies range from relatively small projects, such as rehabilitation of damage caused by wheel ruts in the high arctic, to much larger projects, such as attempts to rehabilitate thousands of hectares of Northern Territory wetlands in Australia. Seedbank ecology, economics, remote sensing, community involvement, the role of the wetland consulting industry, and other issues are discussed. In an effort to synthesize information from around the world, Joy Zedler presents a model that allows comparison of projects and may lead to better predictability of project outcomes. In An International Perspective on Wetland Rehabilitation, authors describe planting, engineered structures, prescribed flooding, excavation, and other rehabilitation methods, from Israel to New Zealand to the Netherlands and elsewhere. For the first time, one volume offers an impression of the magnitude and diversity of the field of wetland rehabilitation around the globe.
