Geographical Gradients in Argentinean Terrestrial Mammal Species Richness and Their Environmental Correlates

Table 5

Summary of the results for the geographical and spatial trends of each mammal group. Geographical trends (a) rSR-Env: environmental variables significantly correlated with SR, rGeo-Env: environmental variables significantly correlated with geographical variables. (b) rSF/Env: environmental variables significantly correlated with spatial filters. In bold environmental variables that explain the geographical or spatial trends. n.s: nonsignificant, * . Variable codes as in Table 1 and Figure 2.
