Download Humic Substances in Terrestrial Ecosystems Book in PDF, ePub and Kindle
This book highlights the increasing importance of humic substances in the different scientific fields related to terrestrial ecology, soil quality conservation, and environmental chemistry. It shows that modern humic substances research is not only directed to unravel their yet ill-defined chemical structure but is successfully exploring the interconnected chemical, biological, and physical processes that maintain the ecological equilibrium of soil and ensure a sustainable agricultural production. The book will primarily be of interest to soil scientists and to ecological and environmental scientists. People in the fields of forest science, agronomy, analytical and environmental chemistry, water science, environmental engineering, and coal science will also find this publication worthy of their attention.

Download Ecology of Humic Substances in Freshwaters Book in PDF, ePub and Kindle
Humic Substances color all waters more or less brown. Their concentrations exceed all carbon of living organisms by at least one order of magnitude. Opposite to former paradigms, they participate in almost any metabolic pathway. They protect against UV-irradation, enable indirect photolysis and, thus, purify hazardous chemicals, they provide inorganic and organic nutrients, may form cryptic genes with DNA and dampen metabolic fluctuations. More recently they can increase adverse effects of hazardous chemicals and they can directly interfere with organisms. The book tries to relate effects to structural features.

Download Aquatic Humic Substances Book in PDF, ePub and Kindle
Humic substances occur in all kinds of aquatic systems, but are particularly important in northern, coniferous areas. They strongly modify the aquatic ecosystems and also constitute a major problem in the drinking water supply. This volume covers all aspects of aquatic humic substances, from their origin and chemical properties, their effects on light and nutrient regimes and biogeochemical cycling, to their role regarding organisms, productivity and food web organization from bacteria to fish. Special emphasis is paid to carbon cycling and food web organization in humic lakes, but aspects of marine carbon cycling related to humus are treated as well.

Download Detritus and Decomposition in Ecosystems Book in PDF, ePub and Kindle
The present book is a detailed assessment of the pools and fluxes of detritus in aquatic and terrestrial ecosystems. Besides presenting a comprehensive analysis of the process of detritus decomposition, the book gives an exhaustive account of the biotic and abiotic factors affecting the rate of detritus decomposition. Portrayal of the role of decomposition in nutrient cycling and delineation of the contemporary concepts of humus biosynthesis are the noteworthy features of this book. The book would be serve the needs of post-graduate students having Ecology as one of their major subject and researchers engaged in soil biology and biochemistry, soil sciences and ecosystem structure and function. The present book attempts to bring together the enormous but fragmented information and fill this lacuna. It has been designed to outline the basic and fundamental aspects of detritus and its decomposition to be understood in their right perspective and envisages to put forward a clear understanding of the current concepts of this fundamental aspect of ecology and its widening horizons.

Download Effects of Acid Precipitation on Terrestrial Ecosystems Book in PDF, ePub and Kindle
This volume contains papers presented at a NATO Advanced Research Institute, sponsored by their Eco-Sciences Panel, on "The effects of acid precipitation on vegetation and soils," held at Toronto, Canada from May 22-26, 1978. The organizing expenses and greater part of the expenses of the speakers and chair~en were provided by N.A.T.O. The scientific programme was planned by T. C. Hutchinson together with an international planning committee of G. Abrahamsen (Norway), G. Likens (U.S.A.), F.E. Last (U.K.), C.O. Tamm (Sweden) and B. Ulrich (W. Germany). Many of the dimensions of the 'acid rain' problem are common to countries of northern Europe and North America. The developing awareness over the past ten years of the international nature of the acid rain phenomenon has lead to studies documenting damaging effects on susceptible freshwater bodies. Large areas of the Canadian Pre-Cambrian Shield, with its extension into the United States, and the granitic areas of southern Norwayand Sweden contain lakes which are in the process of acidification. The biological resources of these affected areas are of considerable national concern. However, while clearly damaging effects of acidification on freshwater systems have been well documented, the impact of acid precipitation on terrestrial systems has not been so well understood.

Download Humic Matter in Soil and the Environment Book in PDF, ePub and Kindle
The field of humic matter research has undergone drastic changes in concepts and principles since the first edition of Humic Matter in Soil and the Environment: Principles and Controversies was published more than a decade ago. Still the only book of its kind specifically addressing humic acid principles and controversies, the Second Edition presents the newest advances in humic acid science. Eleven new and rewritten chapters replace the original nine, with updated material representing modern humic acid chemistry. This includes the delineation of organic matter, humus, and humic matter. The book begins by considering organic matter as a whole, describing terrestrial and aquatic organic matter. It examines humus as a mixture of humified and nonhumified organic matter, focusing also on the importance of the nonhumified fraction—plant biopolymers in their original or slightly decomposed forms—as raw materials for formation of the humic fraction. The book then presents concepts of humic matter, referred to as humic acid, covering a range of ideas from traditional views of biopolymers to the latest concepts based on micellar, supramolecular, and nanotube chemistry. The author presents the major pathways of humification and discusses humification theories. He also examines the extraction, isolation, and fractionation of humic matter. The book reviews the chemical composition and model structures of humic acids, the chemical and spectroscopic characterization of humic substances, and the electrochemical properties of humic matter. It also addresses the agronomic, environmental, and industrial (including pharmaceutical) importance of humic matter. This revised and updated edition continues the tradition of providing comprehensive coverage of the genesis, extraction, properties, and impacts of humic matter.
