Table 3. Pearson correlation coefficients (r) between elevation and patch area and tree species richness (S), density (D) and seedling densities (d). Correlations with p < 0.05 are indicated with *, p < 0.01 indicated with **, ns = non-significant. Analyses were not conducted in southern Argentina because of the very low species richness values encountered. Source: Newton and Tejedor (2011).
