Beavers are widely recognised as a keystone species which play a pivotal role in riparian ecology. Their tree felling and dam building behaviours coupled with a suite of other activities create a wealth of living opportunities that are exploited by a range of other species. Numerous scientific studies demonstrate that beaver-generated living environments that are much richer in terms of both biodiversity and biomass than wetland environments from which they are absent. Emerging contemporary studies indicate clearly that the landscapes they create can afford sustainable, cost-effective remedies for water retention, flood alleviation, silt and chemical capture. Beaver activities, especially in...
The Eurasian beaver was near extinction at the start of the twentieth century, hunted across Europe for its fur, meat and castoreum. But now the beaver is on the brink of a comeback, with wild beaver populations, licensed and unlicensed, emerging all over Britain.
Over the last 20 years, there has been a huge increase in the number of scientific papers published on these remarkable creatures, and an authoritative synthesis is now timely. This accessible text goes beyond their natural history to describe the impacts on humans, conflict mitigation, animal husbandry, management, and conservation.
Case Studies in Ecohealth is primarily intended to be a student textbook, using a series of case studies to illustrate key concepts applicable to EcoHealth, with a focus on taking an interdisciplinary approach to solving complex problems at the interface between animals and their environment. Using case studies, the book will illustrate key concepts in ‘EcoHealth’ allowing readers to better understand the strengths and challenges of taking an ‘Eco Health’ approach Within the key themes addressed in the book, the reader will gain insight into how to approach complex problems at the animal-environment interface using a transdisciplinary approach Access to the case studies presented in the book, along with supplementary material on line, will provide the reader with good examples of current and emerging issues for discussion in the class room or for field experience programs 5m Books
This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.
This classic, definitive reference work for all those involved in environmental health is now available in its 19th edition. Significant changes include those made to chapters on food safety and hygiene, environmental protection, the organisation and management of environmental health in the UK, port health, and waste management. New chapters have been added on health development, an introduction to health and housing, contaminated land, and environmental health in emergency planning, as well as a new glossary of abbreviations and acronyms. New material on training and standards, IT, practical risk assessment, and investigatory powers is also included. Each chapter reflects the wider background against which the subjects must be studied and the new concepts and approaches that have emerged over the past few years.
Since the early 1990s - in the face of outright opposition from government, landowning elites and even some conservation professionals - Derek Gow has imported, quarantined and assisted the reestablishment of beavers in waterways across England and Scotland. 'Bringing Back the Beaver' is farmer-turned-ecologist Gow's inspirational and often riotously funny firsthand account of how the movement to rewild the British landscape with beavers has become the single most dramatic and subversive nature conservation act of the modern era.
