Book excerpt: Earth's climate is changing, and by the end of the 21st century in Europe, average temperatures are likely to have risen by at least 2 °C, and more likely 4 °C with associated effects on patterns of precipitation and the frequency of extreme weather events. Attention among policy-makers is divided about how to minimise the change, how to mitigate its effects, how to maintain the natural resources on which societies depend and how to adapt human societies to the changes. Natural systems are still seen, through a long tradition of conservation management that is largely species-based, as amenable to adaptive management, and biodiversity, mostly perceived as the richness of plant and vertebrate communities, often forms a focus for planning. We argue that prediction of particular species changes will be possible only in a minority of cases but that prediction of trends in general structure and operation of four generic freshwater ecosystems (erosive rivers, depositional floodplain rivers, shallow lakes and deep lakes) in three broad zones of Europe (Mediterranean, Central and Arctic-Boreal) is practicable. Maintenance and rehabilitation of ecological structures and operations will inevitably and incidentally embrace restoration of appropriate levels of species biodiversity. Using expert judgement, based on an extensive literature, we have outlined, primarily for lay policy makers, the pristine features of these systems, their states under current human impacts, how these states are likely to alter with a warming of 2 °C to 4 °C and what might be done to mitigate this. We have avoided technical terms in the interests of communication, and although we have included full referencing as in academic papers, we have eliminated degrees of detail that could confuse broad policy-making.

Available in PDF, EPUB and Kindle. Book excerpt: Pearly mussels (Unionoidea) live in lakes, rivers, and streams around the world. These bivalves play important roles in freshwater ecosystems and were once both culturally and economically valuable as sources of food, pearls, and mother-of-pearl. Today, however, hundreds of species of these mussels are extinct or endangered. David L. Strayer provides a critical synthesis of the factors that control the distribution and abundance of pearly mussels. Using empirical analyses and models, he assesses the effects of dispersal, habitat quality, availability of fish hosts, adequate food, predators, and parasites. He also addresses conservation issues that apply to other inhabitants of fresh waters around the globe and other pressing issues in contemporary ecology.

Download or read book Freshwater Ecology written by Gerry Closs and published by John Wiley & Sons. This book was released on 2009-04-01 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater ecosystems are under increasing pressure as human populations grow and the need for clean water intensifies. The demand for ecologists and environmental managers who are trained in basic freshwater ecology has never been greater. Students and practitioners new to the field of freshwater ecology and management need a text that provides them with an accessible introduction to the key questions while still providing sufficient background on basic scientific methods. Gerry Closs, Barbara Downes and Andrew Boulton have written a text that meets the requirements of these students. Following an introduction to scientific methodology and its application to the study of ecology, several key concepts in freshwater ecology are reviewed using a wide range of scientific studies into fundamental and applied ecological questions. Key ecological questions that are explored in a freshwater context include the role of animal dispersal and predators on freshwater community structure and the impact of pollutants and introduced species on freshwater ecosystems. This book represents the only freshwater ecology textbook that is specifically aimed at an introductory level. It will also be a useful primer for students who have not previously taken a specialized freshwater course but who require an accessible overview of the subject. General reviews on the methods of science, influence of scale, and the main features of freshwater systems. Coverage of several fundamental and applied ecological questions. A logical structure in each chapter that builds from a general observation of an ecological pattern, to an exploration of the various scientific approaches that can be used to investigate such patterns. Suggested further reading lists for each chapter.

Download or read book Biology of Freshwater Crayfish written by David M Holdich and published by Wiley-Blackwell. This book was released on 2001-12-21 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crayfish are the largest, mobile freshwater invertebrates with some 540 recognised species. They are of long standing interest to anatomists and physiologists. For their great commercial importance as a human food delicacy, crayfish are now becoming of wider interest to molecular biologists, and also to conservationists due to the fact that in some countries many of the native crayfish species are under threat from human activity, disease, and competition from other introduced crayfish species. This fully comprehensive book covers all major aspects of these important animals, including taxonomy, anatomy, evolution, growth and reproduction, behaviour, ecology, physiology, conservation, genetics, immunology, environmental aspects, and diseases. There are separate chapters on each genus of crayfish of commercial importance. Written by 22 well-known experts, Biology of Freshwater Crayfish has been carefully edited by David Holdich, internationally recognised for his work with these animals. The book is an essential purchase for anyone involved with the biology or exploitation of crayfish, including freshwater and invertebrate biologists and personnel involved in fisheries and aquaculture. Libraries in all universities and research establishments where biological sciences, fisheries or aquaculture are studied or taught should have copies of this important book on their shelves.

Available in PDF, EPUB and Kindle. Book excerpt: Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.

Download or read book Bioassessment of Freshwater Ecosystems written by Robert C. Bailey and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic ecosystem assessment is a rapidly developing field, and one of the newer approaches to assessing the condition of rivers and lakes is the Reference Condition Approach. This is a significant advancement in biomonitoring because it solves the problem of trying to locate nearby control or reference sites when studying an ecosystem that may be degraded, a problem that bedevils traditional approaches. Rather than using upstream reference sites in a river system or next-bay-over reference sites in a lake, an array of ecologically similar, least-exposed to stress sites scattered throughout a catchment or region is used. Once the reference condition has been established, any site suspected of being impacted can be assessed by comparison to the reference sites, and its status determined. The Reference Condition database, once formed, can be used repeatedly.
