Mean standardized effect size (SES) of the functional diversity index (FDis) and SES of C-Scores (triangles) along the aridity gradient in the Atacama Desert as indicated by DEMAI (De Martonne Aridity Index) at the patch and neighborhood scale for: (a,d) all traits, (b,e) aboveground traits, (c,f) belowground traits. *Indicates significant statistical differences from the null expectation based on two tailed t-tests for FDis and, filled orange triangles represent SES C-scores values significantly different from the null expectation. Lower DEMAI index values indicate greater aridity. QL Quebrada El León, LLCHA Norte Llanos de Challe, CHA Chañaral de Aceituno, ROM Romeral.
