Abstract

Several potential components of competitive ability were determined for 13 plant species in a N-limited alpine moist meadow community in order to determine if competition had an influence on relative abundance in this stressful environment. The components of competitive ability examined were 15N uptake rate, 15N allocation, whole plant biomass, root:shoot ratio and tissue N concentrations. It was hypothesized that 15N uptake rate would be the component most correlated with relative abundance.
