Download or read book Bioindicators and Environmental Management written by Bozzano G Luisa and published by Academic Press. This book was released on 1991-09-26 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: This essential book contains material presented at a September 1990 meeting organized by the Commission for Bioindicators, International Union for Biological Sciences.**A key role of the Commission for Bioindicators (IUBS) is to promote the use of bioindicators in environmental management. This means encouraging the transfer of ideas regarding potential bioindicators, and originating in laboratories, into the harsher realities of field environmental monitoring. Although the concept of biomonitoring is ancient, its application to current monitoring problems is relatively slow to develop.**In a bid to rectify this problem, this invaluable book brings together and discusses approaches developed around the world. It will provide both environmental administrators and research scientists with a valuable sense of proportion of the state of the art in their particular field. - Bioindicators and Environmental Management is organized into four sections - Bioindicators, industry, and administration - Biomonitoring of the Chernobyl accident - Monitoring long-term/large-scale environmental trends - Basic research in biomonitoring

Download or read book Modern Trends in Applied Aquatic Ecology written by R.S. Ambasht and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organisms and environment have evolved through modifying each other over millions of years. Humans appeared very late in this evolutionary time scale. With their superior brain attributes, humans emerged as the most dominating influence on the earth. Over the millennia, from simple hunter-food gatherers, humans developed the art of agriculture, domestication of animals, identification of medicinal plants, devising hunting and fishing techniques, house building, and making clothes. All these have been for better adjustment, growth, and survival in otherwise harsh and hostile surroundings and climate cycles of winter and summer, and dry and wet seasons. So humankind started experimenting and acting on ecological lines much before the art of reading, writing, or arithmetic had developed. Application of ecological knowledge led to development of agriculture, animal husbandry, medicines, fisheries, and so on. Modem ecology is a relatively young science and, unfortunately, there are so few books on applied ecology. The purpose of ecology is to discover the principles that govern relationships among plants, animals, microbes, and their total living and nonliving environmental components. Ecology, however, had remained mainly rooted in botany and zoology. It did not permeate hard sciences, engineering, or industrial technologies leading to widespread environmental degradation, pollution, and frequent episodes leading to mass deaths and diseases.

Download or read book Ecological Risk Assessment written by Glenn W. Suter II and published by CRC Press. This book was released on 1992-10-23 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, environmental scientists have been required to perform a new type of assessment-ecological risk assessment. This is the first book that explains how to perform ecological risk assessments and gives assessors access to the full range of useful data, models, and conceptual approaches they need to perform an accurate assessment. It explains how ecological risk assessment relates to more familiar types of assessments. It also shows how to organize and conduct an ecological risk assessment, including defining the source, selecting endpoints, describing the relevant features of the receiving environment, estimating exposure, estimating effects, characterizing the risks, and interacting with the risk manager. Specific technical topics include finding and selecting toxicity data; statistical and mathematical models of effects on organisms, populations, and ecosystems; estimation of chemical fate parameters; modeling of chemical transport and fate; estimation of chemical uptake by organisms; and estimation, propagation, and presentation of uncertainty. Ecological Risk Assessment also covers conventional risk assessments, risk assessments for existing contamination, large scale problems, exotic organisms, and risk assessments based on environmental monitoring. Environmental assessors at regulatory agencies, consulting firms, industry, and government labs need this book for its approaches and methods for ecological risk assessment. Professors in ecology and other environmental sciences will find the book's practical preparation useful for classroom instruction. Environmental toxicologists and chemists will appreciate the discussion of the utility for risk assessment of particular toxicity tests and chemical determinations.

Available in PDF, EPUB and Kindle. Book excerpt: The environment is considered the surroundings in which an organism operates, including air, water, land, natural resources, flora, fauna, humans and their interrelation. It is this environment which is both so valuable, on the one hand, and so endangered on the other. And it is people who are by and large ruining the environment both for themselves and for all other organisms. This book reviews the latest research in this field which is vital for everyone.

Download or read book Biomonitoring of Trace Aquatic Contaminants written by David J.H. Phillips and published by Springer Science & Business Media. This book was released on 1994 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twenty years ago, researchers wishing to identify contaminated areas in aquatic environments generally took water samples, and analysed them badly (as we have since discovered) for a few "pollutants" which were of topical note at the time (and which could be quantified by the methods then available). Today, the use of aquatic organisms as biomonitors in preference to water analysis has become commonplace, and many national and interna tional programmes exist around the world involving such studies. We believe that this trend will continue, and have complete faith in the methodology (when it is employed correctly). We hope that the following text assists in some part in attaining this goal, such that the quality of our most basic global resource -water - is adequately protected in the future. DAVE PHILLIPS, PHIL RAINBOW England, March 1992 vii Acknowledgements Our thanks for contributions to this book are due to several individuals and groups, for varying reasons. Firstly, a co-authored book is always a triumph, and we trust that the following text is an acceptable compromise of the views of two individual authors, on a complex and developing topic. Secondly, many of the ideas herein have crystallised over the last two decades as the field has grown, and we are individually and collectively grateful to a number of researchers for their insight and assistance.

Download or read book Management of Freshwater Biodiversity written by Julian Reynolds and published by Cambridge University Press. This book was released on 2011-11-10 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrating research into freshwater biodiversity and the role of keystone species, this fascinating book presents freshwater crayfish as representatives of human-exacerbated threats to biodiversity and conservation. It uses examples from these and other large decapod invertebrates to explore how communities function and are controlled, alongside the implications of human demands and conflicts over limited resources, notably the severe impacts on biodiversity. The discussion is structured around three key topics – the present situation of crayfish in world freshwater ecosystems, the applications of science to conservation management and knowledge transfer for successful crayfish management. It outlines the historic exploitation of crayfish, addressing the problems caused by invasive alien forms and explaining the importance of correct identification when dealing with conservation issues. Offering a global perspective on freshwater systems, the book ultimately highlights how the conservation of such large and long-lived species will help protect ecosystem quality in the future.

Download or read book Periphyton written by M. E. Azim and published by CABI. This book was released on 2005-11-18 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first comprehensive monograph on periphyton, this book contains contributions by scientists fromaround the globe. Multi-disciplinary in nature, it covers both basic and applied aspects of periphyton,and is applicable worldwide in natural, extensive and intensive managed systems.Periphyton, as described in this book, refers to the entire complex of attached aquatic biota on submergedsubstrates, including associated non-attached organisms and detritus. Thus the periphyton communitycomprises bacteria, fungi, protozoa, algae, zooplankton and other invertebrates. Periphyton is importantfor various reasons: as a major contributor to carbon fixation and nutrient cycling in aquatic ecosystems;as an important source of food in aquatic systems; as an indicator of environmental change. It can alsobe managed to improve water quality in lakes and reservoirs; it can greatly increase aquaculture production;it can be used in waste water treatment.The book provides an international review of periphyton ecology, exploitation and management. Theecology part focuses on periphyton structure and function in natural systems. The exploitation part coversits nutritive qualities and utilization by organisms, particularly in aquaculture. The final part considersthe use of periphyton for increasing aquatic production and its effects on water quality and animal healthin culture systems. This book will help scientists and entrepreneurs further understand the ecology andproduction of aquatic systems and venture into new and promising areas.

Download or read book Biological Indicators of Freshwater Pollution and Environmental Management written by J.M. Hellawell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: The preface of a book often provides a convenient place in which the author can tender his apologies for any inadequacies and affords him the facility to excuse himself by reminding the reader that his art is long but life, or at least the portion of it in which he has the opportunity for writing books, is short. I, too, am deeply conscious that I have undertaken a task which I could not hope to complete to my own satisfaction but I offer, in self defence, the observation that, inadequate though it is, there is no other book extant, so far as I am aware, which provides the information contained herein within the covers of a single volume. Often during the last decade, in discharging my responsibilities for the environmental aspects of the water authority's operations and works, I should have been deeply grateful to have had access to a compendium such as this. The lack of a convenient source of data made me aware of the need which I have attempted to fill and in doing so I have drawn on my experiences of the kinds of problem which are presented to biologists in the water industry. The maxim 'half a loaf is better than none' seems particularly apt in this context.

Download or read book The Seine River Basin written by Nicolas Flipo and published by Springer Nature. This book was released on 2021-01-30 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book reviews the water-agro-food and socio-eco-system of the Seine River basin (76,000 km2), and offers a historical perspective on the river’s long-term contamination. The Seine basin is inhabited by circa 17 million people and is impacted by intensive agricultural practices and industrial activities. These pressures have gradually affected its hydrological, chemical and ecological functioning, leading to a maximum chemical degradation between the 1960s and the 1990s. Over the last three decades, while major water-quality improvements have been observed, new issues (e.g. endocrine disruptors, microplastics) have also emerged. The state of the Seine River network, from the headwaters to estuary, is increasingly controlled by the balance between pressures and social responses. This socio-ecosystem provides a unique example of the functioning of a territory under heavy anthropogenic pressure during the Anthropocene era. The achievements made were possible due to the long-term PIREN Seine research program, established in 1989 and today part of the French socio-ecological research network “Zones Ateliers”, itself part of the international Long-term Socio-economic and Ecological Research Network (LTSER). Written by experts in the field, the book provides an introduction to the water budget and the territorial metabolism of the Seine basin, and studies the trajectories and impact of various pollutants in the Seine River. It offers insights into the ecological functioning, the integration of agricultural practices, the analysis of aquatic organic matter, and the evolution of fish assemblages in the Seine basin, and also presents research perspectives and approaches to improve the water quality of the Seine River. Given its scope, it will appeal to environmental managers, scientists and policymakers interested in the long-term contamination of the Seine River.
