This book was released on 2013-10-22 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Principles and Methods for Determining Ecological Criteria on Hydrobiocenoses is a collection of papers presented at the 1975 European Scientific Colloquium on Principles and Methods for Determining Ecological Criteria on Hydrobiocenoses, held in Luxembourg. This Colloquium aims to define a scientific basis for assessing the results of pollution on aquatic fauna and flora, as well as the biological methods to be used in assessing the extent of such pollution. This book is organized into four parts encompassing 29 chapters. After a brief overview of a series of parameters for the specific uses of different water classifications and regional evaluation of water pollution, this book goes on examining the ecological consequences of water pollution establishment of criteria and the ecological variable and their effect on aquatic fauna. These topics are followed by a discussion of the value of aquatic plants in water quality characterization, as well as the principles of the methods used. The succeeding parts highlight the concepts and practical methods used in the biological monitoring of surface waters. These parts particularly consider the benefits of using bioindicators and laboratory bioassays. The concluding discusses a comparative study of biological-ecological water assessment methods of water quality. This book will be of value to environmental scientists, engineers, and researchers.

Book excerpt: Research into ecotoxicology can be classified into three fundamental concerns: abiotic factors, which characterize the physicochemistry of environments; biotic factors, relating to biological structures and functions; and contamination factors, which define the modes of pollution of ecosystems. The most significant research methodologies currently being developed in aquatic ecotoxicology are presented, specifically experimental approaches in the laboratory

Available in PDF, EPUB and Kindle. Book excerpt: O. L. LANGE, P. S. NOBEL, C. B. OSMOND, and H. ZIEGLER In the last volume of the series 'Physiological Plant Ecology' we have asked contributors to address the bases of ecosystem processes in terms of key plant physiological properties. It has often been suggested that it is not profitable to attempt analysis of complex living systems in terms of the properties of component individuals or populations, i. e. , the whole is more than the sum of its parts. Nevertheless, assessments of ecological research over the last century show that other approaches are seldom more helpful. Although it is possible to describe complex systems of living organisms in holistic terms, the most useful descriptions are found in terms of the birth, growth and death of individ uals. This allows analysis of performance of the parts of the whole considering their synergistic and antagonistic interrelationships and is the basis for a synthe sis which elucidates the specific properties of a system. Thus it seems that the description of ecosystem processes is inevitably anchored in physiological under standing. If enquiry into complex living systems is to remain a scientific exercise, it must retain tangible links with physiology. Of course, as was emphasized in Vol. 12A, not all of our physiological understanding is required to explore ecosystem processes. For pragmatic purposes, the whole may be adequantely represented as a good deal less than the sum of its parts.

Download or read book River Plants of Western Europe written by S. M. Haslam and published by Cambridge University Press. This book was released on 2014-05-08 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1987, this book describes and discusses the vegetation of rivers and other watercourses in Europe with an emphasis upon distributional, community and historical ecology. It was firmly based upon many years of field investigations carried out by the author in various countries in the European Economic Community. The main purpose of the text was to increase the understanding of river vegetation in relation to the varying physical characteristics of the watercourses. The rivers of the EEC are considered in detail, with an emphasis upon the influences of landscape, geology, climate, settlement patterns, water use and management and pollution. This book will be of value to anyone with an interest in river botany.
Download or read book Contaminants in the Environment written by Aristeo Renzoni and published by CRC Press. This book was released on 1994-08-10 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a broad, interdisciplinary assessment of the hazards presented by direct and indirect environmental contaminants to humans. It explores disparate aspects of risk assessment ranging from molecular mechanisms to the practical and administrative issues of environmental management. The book's first three sections focus on principles relevant to living organisms in general, the fourth addresses the question of risks to human health, while the final section considers issues relevant to both "human" and "natural" environments.
Download or read book Management of Freshwater Fisheries written by Jacques Arrignon and published by . This book was released on 1999 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: Management of Freshwater Fisheries deals with a class of aquatic animals, fish, with particular reference to a human activity, fishing, that can be a means of livelihood or a pastime. The tested data are presented in a clear and well-balanced manner, often with the help of tables, and illustrated with many sketches and photographs. A glossary and an index make this book a useful practical guide. This book will be useful to professionals involved in the biology, management and protection of the aquatic medium: hydrobiologists, aquaculturists, fish farmers, technicians and fishing wardens.
