Methods of studying population shifts in aquatic bacteria in response to environmental change [electronic resource] / Maxine A. Holder-Franklin ; scientific editor, D.B. Carlisle. Ottawa : Environment Canada, Inland Waters Directorate, 1981, c1982. viii, 107 p. : ill. Scientific series ; no. 124 Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "Population shifts in heterotrophic aquatic bacteria from a watershed with several months of ice cover annually and a temperature range of 0°C to 28°C have been studied by classical and numerical taxonomy, factor analysis and species diversity. Mathematical techniques have been utilized to demonstrate correlations between changes in the bacterial populations and certain physico-chemical environmental parameters"--Abstract.
