Silver Shoals: Five Fish That Made Britain

by Charles Rangeley-Wilson

On these rain-swept islands in the North Atlantic man and fish go back a long way. Fish are woven through the fabric of the country’s history: we depend on them – for food, for livelihood and for fun – and now their fate depends on us in a relationship which has become more complex, passionate and precarious in the sophisticated 21st Century.In Silver Shoals Charles Rangeley-Wilson travels north, south, east and west through the British Isles tracing the histories, living and past, of our most iconic fish – cod, carp, eels, salmon and herring – and of the fishermen who catch them and care for them. In the company of trawlermen, longshoremen, conservationists and anglers Charles goes to sea in a trawler, whiles away hot afternoons setting eel nets, tries to bag his first elusive carp and drifts for herring on Guy Fawkes night as fireworks starburst the sky. Underscoring this journey is a fascinating historical exploration of these creatures that have shaped our island story. We learn how abundant and valued these fish were centuries before our current crisis of over-fishing: we learn how eels built our monasteries, how cod sank the Spanish Armada, how fish and chips helped us through two World Wars. Of course there is a deeper environmental dimension to the story, but Charles' optimistic perspective is this: no one is more invested in fish than the fishermen whose lives depend on them. If we can find a way to harness that passion then the future of fish and fishermen in Britain could be as extraordinary as its past.

Fluoride Toxicity in Animals (SpringerBriefs in Animal Sciences)

by Rakesh Ranjan Amita Ranjan

This book describes in detail various aspects of fluoride toxicity in animals. Animals, like human beings, suffer from the toxic effects of excess fluoride intake. They show pathological changes in their teeth and bone, together with a marked reduction in appetite, productive and reproductive potentials, which can result in severe economic losses in the dairy industry. Laboratory and wild animals also suffer from this ailment. Animal suffering and economic losses alike can be minimized through early diagnosis of the problem and by adopting suitable preventive and therapeutic measures. The book details the susceptibility of different animal species, important sources of toxicity, clinical signs and symptoms, pathophysiology, diagnostic methods, preventive and therapeutic approaches. It offers a valuable resource for scientists working in the fields of toxicology, veterinary science, animal nutrition, and environmental science, as well as for public health workers, animal welfare activists, public health veterinarians, field veterinarians, medical professionals and all others interested in the subject.

Fish Ecophysiology (Fish & Fisheries Series #9)

by J.C. Rankin Frank B. Jensen

Among the fishes. a remarkably wide range of biological adaptations to diverse habitats has evolved. As well as living in the conventional habitats of lakes. ponds, rivers, rock pools and the open sea, fish have solved the problems of life in deserts. in the deep sea. in the cold antarctic. and in warm waters of high alkalinity or of low oxygen. Along with these adaptations, we find the most impressive specialisations of morphology, physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins. sailfish and warm-blooded tunas, air-breathing in catfish and lungfish. parental care in the mouth-brooding cichlids and viviparity in many sharks and toothcarps. Moreover, fish are of considerable importance to the survival of the human species in the form of nutritious. delicious and diverse food. Rational exploi­ management of our global stocks of fishes must rely upon a detailed tation and and precise insight of their biology. The Chapman [.,. Hall Fish and Fisheries series aims to present timely volumes reviewing important aspects of fish biology. Most volumes will be of interest to research workers in biology. zoology. ecology and physiology but an additional aim is for the books to be accessible to a wide spectrum of non-specialist readers ranging from undergraduates and postgraduates to those with an interest in industrial and commercial aspects of IIsh and t1sheries.

Managing Protected Areas in Central and Eastern Europe Under Climate Change (Advances in Global Change Research #58)

by Sven Rannow Marco Neubert

Beginning with an overview of data and concepts developed in the EU-project HABIT-CHANGE, this book addresses the need for sharing knowledge and experience in the field of biodiversity conservation and climate change. There is an urgent need to build capacity in protected areas to monitor, assess, manage and report the effects of climate change and their interaction with other pressures. The contributors identify barriers to the adaptation of conservation management, such as the mismatch between planning reality and the decision context at site level. Short and vivid descriptions of case studies, drawn from investigation areas all over Central and Eastern Europe, illustrate both the local impacts of climate change and their consequences for future management. These focus on ecosystems most vulnerable to changes in climatic conditions, including alpine areas, wetlands, forests, lowland grasslands and coastal areas. The case studies demonstrate the application of adaptation strategies in protected areas like National Parks, Biosphere Reserves and Natural Parks, and reflect the potential benefits as well as existing obstacles. A general section provides the necessary background information on climate trends and their effects on abiotic and biotic components. Often, the parties to policy change and conservation management, including managers, land users and stakeholders, lack both expertise and incentives to undertake adaptation activities. The authors recognise that achieving the needed changes in behavior – habit – is as much a social learning process as a matter of science-based procedure. They describe the implementation of modeling, impact assessment and monitoring of climate conditions, and show how the results can support efforts to increase stakeholder involvement in local adaptation strategies. The book concludes by pointing out the need for more work to communicate the cross-sectoral nature of biodiversity protection, the value of well-informed planning in the long-term process of adaptation, the definition of acceptable change, and the motivational value of exchanging experience and examples of good practice.

Genotoxicology of N-Nitroso Compounds (Topics in Chemical Mutagenesis)

by T. Rao

Toph's in Chemical Mutagenesis is a new series dedicated to studies in the areas of environmental chemical mutagenesis and genetic toxicology. In this series we will explore some of many topics that are emerging in these rapidly developing fields. The purpose of the present volume is to attempt to organize and compare the genotoxic properties of the N-nitroso compounds. This is a particularly interesting class of compounds because of the problems encountered with the Salmonella assay of Ames in generating both false positive and false negative results. The battery approach using a number of assay systems seems more appropriate to evaluate chemicals in this class. Topics to be discussed in other volumes in this series include single-cell mutation monitoring systems, the detection of genetic damage in mammalian germ cells, the mutagenicity of pesticides, problems in monitoring human populations in genetic toxicology, and a glossary of terms in genetic toxicology. All of these books are in various stages of development and should appear within the next few years. Frederick J. de Serres Series Editor vii Preface During the past ten years there has been an explosive development in the number of short-term tests to predict the biological risks, especially risks of cancer, in exposure to xenobiotic chemicals. The number of published articles in this area has reached many thousands a year and there are several new journals devoted almost entirely to the presentation of the results obtained in these tests.

The Kirtland's Warbler: The Story of a Bird's Fight Against Extinction and the People Who Saved It

by William Rapai

This book looks at the Kirtland’s warbler and wildlife conservation in a way that no other book has. It looks back on the history of this unique bird, examines the people and policies that kept the warbler from extinction, explores the cult of personality that surrounds it, and examines the challenges of the future—all through the eyes of the people who have acted so passionately on its behalf. The story of the Kirtland’s warbler is a story of complex relationships between the bird and its environment, the humans who interact with it, and the complex government policies that affect it. And now, just when it appears that the Kirtland’s warbler has recovered for good, a change in its status may send the warbler’s population into a downward spiral once again.

Language and Cognition: Essays in Honor of Arthur J. Bronstein (Cognition and Language: A Series in Psycholinguistics)

by Lawrence J. Raphael

We are pleased to be able to honor Arthur J. Bronstein with this volume of essays. We are all the more pleased because the volume has consider­ able intrinsic merit, but neither the reader nor Arthur should have any doubts about our primary purpose in assembling this book. That the col­ lection is intrinsically valuable is, in itself, a tribute to the man whom it honors: The contributing authors are all colleagues, students, and friends of Arthur. Readers who are acquainted with Arthur will not be surprised by the broad range of academic expertise which has been brought to bear on the subject of language in this book. They will recognize that Arthur's own range of expertise and interest is only barely matched by the contents of the essays and the backgrounds of their authors. On the other hand, those who know little about Arthur may have thought of him primarily in narrow association with phonetics and lin­ guistics, most likely as the author of The Pronunciation of American English, surely the most influential of American phonetics texts during the last quarter of a century. Although such an association is in many respects appropriate, it is altogether too limited, but this will not deter us from using it as the basis for a relevant and, we hope, revealing metaphor about Arthur J.
