| Abstract | Four benthic macroinvertebrate communities, each subject to a different level of human perturbation, in three Michigan streams were studied during an annual cycle to determine the effects of human perturbation on community composition and species diversity. Species diversity indices derived from information theory were used. The abundance of species decreased and the abundance of individuals generally increased as the level of perturbation increased. Indices of species diversity appear to be highly sensitive indicators of the degree of human perturbation. (Modified author abstract) |
