This book was released on 2012 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intensity and types of land use have changed rapidly in the last century and in north-western Alberta this has coincided with the decline of Wapiti River watershed Arctic Grayling (Thymallus arcticus) populations. Data on diurnal dissolved oxygen (DO), chemical and physical stream habitat data were collected in nine sub-watersheds of the Wapiti River with historically abundant Arctic Grayling populations. Levels and fluctuations of DO and temperature were related to the status of populations; five of the nine streams had higher temperatures and lower DO during summer, anoxic conditions during winter and extirpated populations. Amount of disturbed land and road density within sub-watersheds were inversely related to DO levels and population status. Cumulative effects modelling suggests a possible mechanism for these relationships is increased phosphorous runoff, leading to impaired habitat. These relationships and thresholds may be used as a management tool to maintain or restore Arctic Grayling and other stream fishes.

Book Synopsis Fish Wars and Trout Travesties by : George Colpitts
Download or read book Fish Wars and Trout Travesties written by George Colpitts and published by Athabasca Univ. This book was released on 2020-09-30 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today, efforts at environmental protection commonly take the form of "top-down" measures, in which overarching plans, usually based on scientific reports, are implemented through environmental legislation, which is then enforced at the local level.Fish Wars and Trout Travesties offers an instructive glimpse into an earlier era, before the state assumed its present degree of regulatory control over the environment. In southern Alberta of the 1920s, townspeople and civic leaders took a spirited interest in the management of their local rivers and streams and often held strong opinions about which species of fish should be conserved and by what methods. Often these opinions reflected a growing division between the traditional, rural understanding of nature as the means to survival and an emerging urban conception of nature as recreational space. Such conflicting perspectives – founded, as they were, on differing views about the relationship of human beings to the natural world – meant that local debates could be quite heated.
