Download or read book Coastal Lagoons written by Michael J. Kennish and published by CRC Press. This book was released on 2010-06-15 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by an outstanding group of contributors, this book examines the function and structure of coastal lagoonal ecosystems and the natural and anthropogenic drivers of change that affect them, most notably nutrient over-enrichment from coastal watersheds and airsheds. The contributors target the susceptibility of coastal lagoons to eutrophication, the indicators of eutrophic conditions, the influences of natural factors such as major storms and other climate effects, and the resulting biotic and ecosystem impairments that have developed. The book compares biogeochemical and ecological response to nutrient enrichment and other pollutants in lagoonal estuaries to those in other estuarine types.

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 Evolutionary Biogeography of the Marine Algae of the North Atlantic written by David J. Garbary and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algal systematists, geologists and evolutionary biologists provide a synthesis of the evolutionary biogeography of red, brown, and green algae of the North Atlantic Ocean also considering their relationships with species and genera in the Arctic and Pacific Oceans as well as other subtropical and tropical seas. The history of the Atlantic Basin and its connections to other ocean basins is treated from the geological, paleontological and paleoclimatic perspective. This is contrasted with biogeographic analyses of marine animal systems and the role of plant/animal interactions in evolution. Some of the approaches include traditional systematic studies, cladistic analysis, the experimental evaluation of environment in establishing distribution limits and the application of molecular biology.
Download or read book In the Chamber of Risks written by William Leiss and published by McGill-Queen's Press - MQUP. This book was released on 2001 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: In In the Chamber of Risks William Leiss demonstrates that case studies of risk controversies show that those instincts are unreliable guides to effective risk management and that in all cases the opposite position is a far better guide. As risk management is inherently disputable, public perceptions of risk should be seen as legitimate and treated as such and the public should always be involved in discussions about risk evaluations made by scientists and risk managers. ; Leiss chronicles the erratic course of risk management and communication in environmental management in Canada, discussing the notable controversies that have arisen over pesticides and breast cancer, vinyl toys, genetically engineered food crops, cellular telephones, and antibiotic-resistant bacteria, among many others. He focuses on risk management – how we make decisions about and assess hazards in the environment – and on risk communication – social dialogue that deals with both our intuitive feelings of concern about substances or activities that might hurt our health or the environment, and the scientific and probabilistic description of them. ; Leiss shows that both risk management and risk communication, when properly constructed, require an elaborate process because the very things that can cause harm are in most cases the same things that bring us great benefits, such as paper mills, electricity from nuclear power generating stations, or wireless telecommunications. ;
Download or read book The GEO Handbook on Biodiversity Observation Networks written by Michele Walters and published by Springer. This book was released on 2016-11-25 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biodiversity observation systems are almost everywhere inadequate to meet local, national and international (treaty) obligations. As a result of alarmingly rapid declines in biodiversity in the modern era, there is a strong, worldwide desire to upgrade our monitoring systems, but little clarity on what is actually needed and how it can be assembled from the elements which are already present. This book intends to provide practical guidance to broadly-defined biodiversity observation networks at all scales, but predominantly the national scale and higher. This is a practical how-to book with substantial policy relevance. It will mostly be used by technical specialists with a responsibility for biodiversity monitoring to establish and refine their systems. It is written at a technical level, but one that is not discipline-bound: it should be intelligible to anyone in the broad field with a tertiary education.
Download or read book Biodiversity and Ecology written by Neil Griffin and published by . This book was released on 2019-06-19 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biodiversity refers to the variation of life forms on earth at the genetic, species and ecosystem level. It varies widely across the globe and from region to region. It is dependent on abiotic characteristics of temperature, precipitation, altitude, etc. Biological diversity exists at various levels. These include taxonomic diversity, ecological diversity, morphological diversity and functional diversity. Ecology is a sub-field of biology that studies the interactions between organisms and the environment. The study of biodiversity, its distribution and population of individual organism groups as well as the interaction between systems of organisms are areas of interest in ecology. It has practical applications in conservation biology, wetland management and natural resource management, among many others. The objective of this book is to give a general view of the different areas of biodiversity and ecology, and their applications. It brings forth some of the most innovative concepts and elucidates the unexplored aspects of these fields. For someone with an interest and eye for detail, this book covers the most significant topics relevant to these fields.
Download or read book Global Ecology and Oceanography of Harmful Algal Blooms written by Patricia M. Glibert and published by Springer. This book was released on 2018-04-26 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Harmful algal blooms (HABs) - blooms that cause fish kills, contaminate seafood with toxins, or cause human or ecological health impacts and harm to local economies - are occurring more often, in more places and lasting longer than in past decades. This expansion is primarily the result of human activities, through increased nutrient inputs and various aspects of climate change. The Global Ecology and Oceanography of Harmful Algal Blooms (GEOHAB) programme promoted international collaboration to understand HAB population dynamics in various oceanographic regimes and to improve the prediction of HABs. This volume introduces readers to the overarching framework of the GEOHAB programme, factors contributing to the global expansion of harmful algal blooms, the complexities of HABs in different habitats, and the forward-looking issues to be tackled by the next generation of GEOHAB, GlobalHAB. The programme brought together an international team of contributing scientists and ecosystem managers, and its outcomes will greatly benefit the international research community.
