Book Synopsis Effects of Conifer Release with Herbicides on Wildlife (a Review with an Emphasis on Ontario Forests) by : R. A. Lautenschlager
Download or read book Effects of Conifer Release with Herbicides on Wildlife (a Review with an Emphasis on Ontario Forests) written by R. A. Lautenschlager and published by Sault-Ste. Marie : Ontario Ministry of Natural Resources. This book was released on 1993 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper reviews studies that have examined the effects of forest herbicide treatments on wildlife in Ontario and similar northern coniferous ecosystems. Since most of the research has been short-term, valid generalizations about the effects of conifer release with herbicides on specific wildlife species or groups must be limited to 1 or 2 growing seasons after treatment. Conifer release is only one of several forest management tools designed to direct secondary succession and shape future forests. Managed forests, moreover, are only parts of larger ecosystems, which in turn are parts of the overall landscape. The effects of the composition of the landscape mosaic on resident wildlife should be considered when conifer release is discussed. In Ontario, where harvesting has reduced the coniferous component in forests and landscapes, conifer release could help restore this component and increase both forest and wildlife diversity.

Available in PDF, EPUB and Kindle. Book excerpt: Contains summaries of forest vegetation management research projects being conducted in northern Ontario and visited in field tours during a conference that focused on: alternative methods of vegetation control; ecosystem effects associated with vegetation management practices; and ecosystem management and its implications for forest vegetation management. The three tours had the following themes: plant competition and ecophysiology of forest regeneration; effects of vegetation management on forest ecosystems; and vegetation management in the Great Lakes-St. Lawrence forest.
Book Synopsis Global and Regional Mercury Cycles: Sources, Fluxes and Mass Balances by : W. Baeyens
Download or read book Global and Regional Mercury Cycles: Sources, Fluxes and Mass Balances written by W. Baeyens and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: Essential themes in the biochemical cycling of mercury are the relative importance of anthropogenic versus natural sources, transformation and migration processes at the local, regional and global scale, global emission inventories of different mercury sources (both point and diffuse) of both natural and anthropogenic origin. In this regard, Siberia, with its vast territory and variety of natural zones, is of special interest in the global mercury cycle and in terms of the influence of geographical zones on source and sink terms in regional budgets. Siberia contains large areas of mercuriferous belts; natural deposits that emit mercury into the atmosphere and water. Siberian gold has been mined with the use of mercury since the early 1800s. But there, too, huge forest zones and vast areas of tundra and wetland (bogs) can act as efficient sinks for atmospheric mercury. Audience: Environmental scientists, legislators, politicians and the interested citizen wishing to gain a clear picture of the biogeochemical cycling of mercury.
Download or read book Glyphosate written by John E. Franz and published by . This book was released on 1997 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: Glyphosate is a popular global post-emergent perennial herbicide. This volume is a comprehensive review of glyphosate's history, properties, chemistry, biology, formulation, technology, enzymology, and structure/activity relationship. The discussion covers glyphosate's unique environmental properties, broad range of application, soil inactivity, soil and plant metabolism, low toxicity, and uptake and transport in plants. It also covers the syntheses of hundreds of analogs and derivatives and clarifies glyphosate's molecular mode of action and its effect on the target enzyme EPSP synthase.
