Abstract
E. atherica is a grass species (Triticeae: Poaceae) which can reproduce sexually as well as clonally. It occurs on the higher elevations of European salt marshes. However, during the last decades it has started to invade the lower salt marshes. Seedling recruitment is important during initial colonisation, but over time sexual reproduction may decrease due to intraspecific competition. Competition and stochastic mortality could lead to a net decrease in clonal diversity, thereby increasing the portion of vegetative reproduction. Therefore, it is hypothesised that the ratio of sexual and vegetative reproduction changes towards more vegetative reproduction during colonisation of E. atherica. In this study,clonal diversities in differently sized patches of E. atherica within two populations on lower salt-marsh sites of different age (25 and 35 yrs) were investigated on the island of Schiermonnikoog The Netherlands.
