Download or read book Ecology and Evolution of the Freshwater Mussels Unionoida written by G. Bauer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: All those who think that bivalves are boring are in the best company. Karl von Frisch is reported to have turned the pages more quickly in texts where bivalves were treated because, according to him, they literally lack any behaviour. The fact that they can filtrate huge amounts of water, burrow into the sedi ment, actively swim, drill holes into rocks and boats or detect shadows with the aid of pretty blue eyes located on the rim of their mantle obviously left v. Frisch unimpressed. Why, then, a book on the large freshwater mussels (Naiads or Unionoida), which on first sight are much less spectacular than the marine ones? The main reason is that they are keepers of secrets which they reveal only on close and careful inspection. This is not only true for the pearls some species produce and which over centuries have contributed to the treasures of bishops and kings, but particularly for their ecology: their life cycles are linked with those of fishes, some can occur in incredible densities and some can live for more than 100 years. Thus, the presence or absence of naiads in a lake or stream has manifold implications.

Available in PDF, EPUB and Kindle. Book excerpt: Environmental Chemistry is a relatively young science. Interest in this subject, however, is growing very rapidly and, although no agreement has been reached as yet about the exact content and limits of this interdisciplinary discipline, there appears to be increasing interest in seeing environmental topics which are based on chemistry embodied in this subject. One of the first objectives of Environ mental Chemistry must be the study of the environment and of natural chemical processes which occur in the environment. A major purpose of this series on Environmental Chemistry, therefore, is to present a reasonably uniform view of various aspects of the chemistry of the environment and chemical reactions occurring in the environment. The industrial activities of man have given a new dimension to Environ mental Chemistry. We have now synthesized and described over five million chemical compounds and chemical industry produces about hundred and fifty million tons of synthetic chemicals annually. We ship billions of tons of oil per year and through mining operations and other geophysical modifications, large quantities of inorganic and organic materials are released from their natural deposits. Cities and metropolitan areas of up to 15 million inhabitants produce large quantities of waste in relatively small and confined areas. Much of the chemical products and waste products of modern society are released into the environment either during production, storage, transport, use or ultimate disposal. These released materials participate in natural cycles and reactions and frequently lead to interference and disturbance of natural systems.

Available in PDF, EPUB and Kindle. Book excerpt: Voices for the Watershed is a unique look at the singular and ecologically inter-connected region of the Great Lakes-St Lawrence watershed, including the headwater and upland regions. With contributions from experts from the United States, Quebec, and Ontario, this book offers an accessible introduction to the issues affecting the quality of our most essential and precious of natural resources - clean, fresh water - from headwater regions downstream to the Great lakes, the St Lawrence river, and ultimately the watershed's outflow to the sea. With thoughtful words and evocative photography, Voices for the Watershed promotes understanding and examines ecological problems, describing positive environmental actions and projects as well as ongoing concerns over the effects of pollution on wildlife and human health. The underlying themes throughout are that the drainage basins and ecosystems are under siege - from reckless land use decisions, soil erosion, acid rain, and massive habitat destruction - but that the situation is not hopeless. The authors feel strongly that education about the environmental threats - in the classroom and public forums - is essential to effecting positive change, and that conservation actions by citizen groups and individuals can be a driving force in effecting substantial reforms regarding environmental legislation and practices. Voices for the Watershed is an eye-opening look at not only the problems but possible solutions to help protect and preserve this resilient natural resource on which so many depend.

Download or read book Quagga and Zebra Mussels written by Thomas F. Nalepa and published by CRC Press. This book was released on 2013-10-25 with total page 820 pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction and rapid spread of two Eurasian mussel species, Dreissena polymorpha (zebra mussel) and Dreissena rostriformis bugensis (quagga mussel), in waters of North America has caused great concern among industrial and recreational water users. These invasive species can create substantial problems for raw water users such as water treatment facilities and power plants, and they can have other negative impacts by altering aquatic environments. In the 20 years since the first edition of this book was published, zebra mussels have continued to spread, and quagga mussels have become the greater threat in the Great Lakes, in deep regions of large lakes, and in the southwestern Unites States. Quagga mussels have also expanded greatly in eastern and western Europe since the first book edition was published. Quagga and Zebra Mussels: Biology, Impacts, and Control, Second Edition provides a broad view of the zebra/quagga mussel issue, offering a historic perspective and up-to-date information on mussel research. Comprising 48 chapters, this second edition includes reviews of mussel morphology, physiology, and behavior. It details mussel distribution and spread in Europe and across North America, and examines policy and regulatory responses, management strategies, and mitigation efforts. In addition, this book provides extensive coverage of the impact of invasive mussel species on freshwater ecosystems, including effects on water clarity, phytoplankton, water quality, food web changes, and consequences to other aquatic fauna. It also reviews and offers new insights on how zebra and quagga mussels respond and adapt to varying environmental conditions. This new edition includes seven video clips that complement chapter text and, through visual documentation, provide a greater understanding of mussel behavior and distribution.

Download or read book The Adélie Penguin written by David Ainley and published by Columbia University Press. This book was released on 2002-10-01 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Adélie penguin is one of the best-studied birds in the world and is the subject of research programs from a dozen nations interested in monitoring changes in the environment and the food webs of the Southern Ocean. This species' population has been changing dramatically over the past few decades coincident with a general warming of the maritime portion of Antarctica. When the sea-ice is seen to decline so does the population of Adélie penguins. Further south, however, the population is increasing. This book summarizes our present ecological knowledge of this polar seabird. In so doing, David Ainley describes the ecological factors important to its life history and details the mechanisms by which it is responding to climate change. The author also chronicles the history of research on Adélie penguins, beginning with the heroic expeditions at the beginning of the twentieth century. Weaving together history, ecology, natural history, and written accounts from the earliest Antarctic naturalists into a fascinating account of this charismatic bird, The Adélie Penguin provides a foundation upon which future ornithological research and environmental monitoring can be based. It is a model for investigations into the effect of climate change on a particular species. The book also contains many fine illustrations from the accomplished illustrator Lucia deLeiris and photographs by the author.

Available in PDF, EPUB and Kindle. Book excerpt: Today′s chemists need to know how hazardous the chemicals they work with are, and they want to understand the relationship between chemical and structural properties and toxicity. At the same time, modern society requires that chemists have this kowledge, as legislation makes the producers/users of chemicals responsible for any adverse effects. The book deals with the effects on both man and ecosystems. It stresses especially on the relationship between chemical structure and chemical properties/toxic effects and metabolic conversions. This is not just another book on toxicology. What makes this book special is that it is written from a chemical point of view. This textbook applies the basic principles of reactivity and reaction possibilities of organic compounds to metabolic reactions and living systems.
