Book Description
Many books have now been published in the broad field of environmental toxicology. However, to date, none of have presented the often fascinating stories of the wildlife science, and the steps along the way from discovery of problems caused by environmental pollutants to the regulatory and non-regulatory efforts to address the problems. This book provides case by case examinations of how toxic chemical effects on wildlife have brought about policy and regulatory decisions, and positive changes in environmental conditions. Wild animal stories, whether they are about the disappearance of charismatic top predators, or of grossly deformed embryos or frogs, provide powerful symbols that can and have captured the public's imagination and have resulted in increased awareness by decision makers. It is the intent of this book to present factual and balanced overviews and summaries of the science and the subsequent regulatory processes that followed to effect change (or not). We cover a variety of chemicals and topics beginning with an update of the classic California coastal DDT story of eggshell thinning and avian reproduction to more recent cases, such as the veterinarian pharmaceutical that has brought three species of Asian vultures to the brink of extinction. Researchers, regulators, educators, NGOs and the general public will find valuable insights into the processes and mechanisms involved both in environmental scientific investigation and in efforts to effect positive change.

Book Description
This guidebook is intended to assist forestry practitioners in British Columbia to meet the requirements of the provincial Forest Practices Code with respect to spacing, or the cutting of undesirable trees within a young stand to reduce competition among the residual trees for water, nutrients, and sunlight. Chapters of the guidebook cover the regulations regarding spacing, the maximum density required by the silviculture prescription, biological criteria and operational considerations for including spacing in stand management prescriptions, fire protection, maintenance of stand-level biodiversity, considerations for post-treatment densities, manual and mechanized methods of spacing, selection of crop trees, monitoring, and reporting. The appendices include stand selection guidelines for use in stand management prescriptions.

Book Description
Forests are valued not only for their economic potential, but also for the biodiversity they contain, the ecological services they provide, and the recreational, cultural, and spiritual opportunities they provide. The Ecological Forest Management Handbook provides a comprehensive summary of interrelated topics in the field, including management con

Book Description
Climate change is now doing far more harm than marooning polar bears on melting chunks of ice—it is damaging the health of people around the world. Brilliantly connecting stories of real people with cutting-edge scientific and medical information, Changing Planet, Changing Health brings us to places like Mozambique, Honduras, and the United States for an eye-opening on-the-ground investigation of how climate change is altering patterns of disease. Written by a physician and world expert on climate and health and an award-winning science journalist, the book reveals the surprising links between global warming and cholera, malaria, lyme disease, asthma, and other health threats. In clear, accessible language, it also discusses topics including Climategate, cap-and-trade proposals, and the relationship between free markets and the climate crisis. Most importantly, Changing Planet, Changing Health delivers a suite of innovative solutions for shaping a healthy global economic order in the twenty-first century.

Book Description
This study is part of a series of research papers that explore the biological, social, and economic aspects of British Columbia's mountain pine beetle epidemic. The objective of this study is to compare two different approaches for calculating beetle pressure, and to assess the impact these approaches have on the subsequent calculation of risk ratings. To meet this objective, beetle pressure was calculated using the traditional distance-based model, as well as using an alternative density-based model, implemented with a Voronoi tessellation generated from helicopter-GPS point survey data of known beetle infestation locations.--Includes text from document.
