Available in PDF, EPUB and Kindle. Book excerpt: The threat of deteriorating habitats and a loss of biodiversity make this reference work on the freshwater fishes of British Columbia more necessary than ever before. Eighty-one comprehensive species accounts aid accurate identification and consist of an illustration, the scientific and common names of the fish, its distinguishing characteristics, taxonomic comments, geographic distribution, a life-history summary, a habitat-use summary, and conservation comments. The book is a critical resource for biologists, naturalists, management and conservation officers, anglers, and members of the public who are concerned about our natural heritage. Foreword by Joseph S. Nelson.

Download or read book Land Snails of British Columbia written by Robert G. Forsyth and published by . This book was released on 2004 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Snails and slugs have a reputation as slimy, repulsive creatures that are nothing more than garden pests, but they are important components of the ecosystems they live in. In fact, most of the pest slugs and snails are introduced species that have come here with the plants we import for our gardens. Worldwide there are more species of snails and slugs than all the mammals, birds, reptiles and amphibians combined, yet they are often overlooked because of their relatively small size. Land snails and slugs are well adapted to live in almost any kind of environment, from high arctic tundra to tropical forests. In British Columbia, they can be found just about everywhere. Land Snails of British Columbia describes all 92 species of terrestrial molluscs in our province. It includes photographs and detailed drawings of each, diagnostic keys and a selection of colour photographs to aid in identification. With each species description, the author discusses its natural history and distribution in the province. He also talks about reproduction, life history, diet, locomotion and shell structure (even slugs have shells). Nature buffs and anyone interested in looking past the bad reputation of these much-maligned creatures will find this handbook an enlightening guide. For gardeners, this book will tell you which snails to cast out of your garden and which ones to keep, because some snails and slugs are beneficial to gardens and some even prey on their pestilent relatives."--

This book was released on 1997 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents much of what is presently known about the impacts of climate change on a number of sectors in British Columbia and Yukon, and also summarizes outcomes of a climate change workshop. It compiles papers on the following subjects; climate variability and change; impacts on the physical environment, including sea levels, stream flow, glaciers, and geomorphic processes; impacts on natural ecosystems; impacts on economic sectors, managed ecosystems, and lifestyles, including impacts on air quality, agriculture, Aboriginal lifestyles, and energy production; and human responses to climate change, including governmental and industry strategies to reduce greenhouse gas emissions. The appendix includes climate change scenarios for British Columbia and Yukon.

Download or read book Metabolism of Polycyclic Aromatic Hydrocarbons in the Aquatic Environment written by Usha Varanasi and published by CRC Press. This book was released on 1989-03-31 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book shows how the biological transport, bioaccumulation, disposition, and toxicity of polycyclic aromatic hydrocarbons (PAH) in the aquatic environment are influenced by the ability or inability of organisms to metabolize these environmental pollutants. Written by leading scientists in the fields of PAH metabolism and toxicity in both aquatic and mammalian systems, this book discusses recent advances in the areas of PAH biogeochemistry and bioaccumulation, microbial degradation, enzymes of activation, and detoxication, metabolism of PAH, and laboratory and field studies on carcinogenic/toxic effects. Additionally, important similarities and differences in metabolism of PAH by aquatic and terrestrial organisms are featured. The discussion of bioavailability, metabolism, and subsequent toxic effects should aid in the assessment of the ecological consequences of PAH in the aquatic environment.

Available in PDF, EPUB and Kindle. Book excerpt: The last half-century has shown a dramatic increase in the standard of living of millions of people in Europe, North America and many parts of the Third World. This has, in many ways been brought about by scientific and technical developments which were initiated in the 1940s and 1950s. Promises were then made that nuclear energy would provide electricity so cheap that it would not need metering, pesticides would end malnutrition throughout the world and plastics and other synthetic chemicals would revolutionise our manufacturing industry and our way of life. Whilst some of these promises have been fulfilled, the problems of long-term health risks to humans and wildlife arising from the use, production and disposal of these products were either unknown or deliberately understated. Nuclear power is rendered economically unviable when the real cost of decommissioning and storage of waste for several millenia is included, and the effects on health of both humans and wildlife of early pest eradication programmes with organochlorine pesticides were well documented in Rachel Carson's "Silent Spring". Evidence of the effects of aerosols and refrigerants on depletion of the ozone layer has led to restriction on the use of CFCs, and there is now increasing evidence of climate change resulting from our profligate use of fossil fuels.
