Aquatic Oligochaete Biology VI

Recent studies on diverse aspects of the biology of clitellate works (oligochaetes and leeches) are found in the Proceedings of the most recent International Symposium on Aquatic Oligochaete Biology - from development to population dynamics and from ultrastructure to evolution. The majority of the contributions, which have a very broad geographic scope, are investigations of the biology and ecology of oligochaete works in natural and polluted waters.
