Competitive abilities and related strategies in four aquatic plant species from an intermediately disturbed habitat
Summary 1. High species richness in disturbed habitats is commonly attributed to the coexistence of species with diverse competitive abilities and, more generally, to the coexistence of different plant strategies sensu Grime (1977, 1979). The present study tests this assumption for the case of inter...
