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.
