Plant species richness in Riparian wetlands-a test of biodiversity theory
This article presents a study on an Alaskan island which addresses the relationship between species richness in coastal wetlands and three factors: flood frequency, productivity, and spatial heterogeneity. Topographic variations in elevation result in spatial variations in flood frequencies. Areas with high levels of spatial variation and consistent flooding patterns were rich in species variation, while those with permanent or little flooding did not. The dynamic-equilibrium model of species diversity was also reinforced by this data.
