| Abstract |
Fish were collected during the summers 1971 and 1972 from the New River in the vicinity of a synthetic fibers plant, Pearlsburg, Virginia. Data were analyzed by 2 methods and contrasted: the diversity index (d) of Wilhm and Dorris and the Jaccard similarity coeff (Sj).The former is a method currently used in monitoring aquatic ecosystems and is a function of the numbers and kinds of spp found. The latter analyzes only presence or absence data at each station. Sj was easily adapted to this investigation, provided a more critical method of analyzing data, especially where data were redundant, and is recommended as a method for the biological assessment of water quality. |
