An increase in foliar nitrogen isotope composition (δ 15 N) with decreasing precipitation has been shown to occur widely in non-N 2 -fixing plant species. However, similar patterns have not been identified in N 2 -fixing species. Here, we tested the relationships of foliar δ 15 N with local environmental factors and leaf properties in two leguminous shrub species ( Caragana korshinskii and Caragana liouana ) sampled from 30 populations. Results indicated that the mean annual precipitation (MAP) primarily accounted for the variation of foliar δ 15 N in the two species. Further analysis revealed strong negative correlations between foliar δ 15 N and MAP within and across species. These results suggest that the foliar δ 15 N of leguminous shrub species also shift along precipitation gradients, which augments our understanding of the relationships between foliar δ 15 N and climatic factors.
