Issue Title: Theme: Macrophytes in Aquatic Ecosystems: From Biology to Management Proceedings of the 11th International Symposium on Aquatic Weeds, European Weed Research Society The genetic variation and clonality in Callitriche L. populations from 16 headwater rivers in Belgium were determined by random amplified polymorphic DNA (RAPD). It was shown that samples of morphological C. obtusangula can be separated into at least two genetically distinct groups. Both gene pools occurred within each considered river basin, i.e. Nete and Meuse. A multivariate analysis showed that the variability among different clones, as characterized by their genotypes, can be explained through ecological indicator values such as diatom saprobity and environmental variables related to water quality type. This study showed that multilocus genotypes or gene pools might have a non-random distribution in the rivers and in their particular environments.[PUBLICATION ABSTRACT]
