title: Bryophytes with asexual reproduction - Their ability to succeed in an industrial area.
abstract: The extent to which the distribution of liverwort and moss species in the industrial area around Duisburg (Federal Republic of Germany) is influenced by asexual reproduction is studied using distribution data. The research shows that neither the liverworts nor the mosses - except the genus Plagiothecium - are more successful in the area of concentrated industry when they are capable of asexual reproduction.
