Environmental Protection Agency and published by BiblioGov. This book was released on 2013-07 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Environmental Protection Agency (EPA) was introduced on December 2, 1970 by President Richard Nixon. The agency is charged with protecting human health and the environment, by writing and enforcing regulations based on laws passed by Congress. The EPA's struggle to protect health and the environment is seen through each of its official publications. These publications outline new policies, detail problems with enforcing laws, document the need for new legislation, and describe new tactics to use to solve these issues. This collection of publications ranges from historic documents to reports released in the new millennium, and features works like: Bicycle for a Better Environment, Health Effects of Increasing Sulfur Oxides Emissions Draft, and Women and Environmental Health.

Book excerpt: The first Wild Trout Symposium (1974) was sponsored by Trout Unlimited and the United States Department of the Interior. The second Symposium (1979) added the Federation of Fly Fisherman as a sponsor. Five years later (1984) the U.S. Department of Agriculture - Forest Service joined. In 1989 , the U.S. Environmental Protection Agency and the American Fisheries Society joined. These symposia began with a concentration on management, then recognized that more than 'management' was required in ongoing efforts to enhance wild salmonid fisheries. Subsequent symposia began to examine a broader range of environmental and social factors influencing wild salmonids. The originators hoped that each symposium would be a building block upon which the succeeding symposium could provide insights and research which future sessions could revisit. Along with the broadening of sponsorship, we have grown , we have gained recognition, and we look forward to expanding our contribution to the cause of wild salmonids. We hope these Proceedings will stimulate readers thinking and efforts on behalf of our wild salmonid resources , and plan to participate with us in Wild Trout V.

Download or read book River Biota written by Peter P. Calow and published by John Wiley & Sons. This book was released on 2009-07-08 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: As with all ecosystems, river systems involve a complex interaction of a rich diversity of micro-organisms, plants and animals with their physical and chemical environment. The river habitat presents unique problems for organisms exposed to unidirectional currents, seasonal variation in flow, and disturbance due to pollution and other human interference. The book starts with a description of the taxa, their adaptations and their ecologies, followed by chapters describing the ecosystem processes in terms of trophic interactions and the key production processes related to photosynthesis and decomposition. A major chapter then considers the principles, practices and problems associated with making reliable observations on river organisms, leading to final chapters investigating how river biota are impacted by human activity and how, in turn, they can be used as indicators of these effects in river-management programmes.
