Abstract

The distribution and abundance of macroinvertebrates were studied in the South Esk River, Tasmania; a river subject to cadmium and zinc pollution as a result of mining. The groups most intolerant of cadmium‐zinc pollution were the Crustacea, Mollusca and Annelida. Highly tolerant groups included aquatic Hemiptera and Arachnida, and larvae of leptocerid trichopterans. A drop in both species diversity and abundance occurred after floods in winter and was probably due to pulses of cadmium and zinc down the river and also to increased molar action of the unstable substrate.
