Research Abstract

Biodiversity loss has important consequences for a variety of ecosystem processes. We manipulated genotypic richness of the common reed, Phragmites austraslis, in a small-scale experimental system similar to constructed wetlands. Genotypic richness increased plant primary productivity, and this effect was largely explained by niche complementarity among genotypes. Nitrogen loss decreased as genotypic richness increased. Given that water purification through nitrogen removal is achieved by plants and microorganisms around the plant root zone, these results suggest that genetic diversity enhanced water purification possibly by both increased plant productivity and bacterial activity.
