Factors determining plant species richness in Alaskan arctic tundra

Factors determining plant species richness in Alaskan arctic tundra

Journal of Vegetation Science 14(5): 711-720

We studied the relationship between plant N:P ratio, soil characteristics and species richness in wet sedge and tussock tundra in northern Alaska, USA at seven sites. We also collected data on soil characteristics, aboveground biomass, species richness and composition. The N:P ratio of the vegetation did not show any relationship with species richness. The N:P ratio of the soil was related with species richness for both vegetation types.
