Figure S4. Results from the niche comparisons between Tetraglochin species in the environmental (E) space. Niche overlap estimations among Tetraglochin species using the first three axes of the PCA-env. A. PCs 1-2. B. PCs 1-3. C. PCs 2-3. For A-C, left: pairwise niche overlap between each Tetraglochin species quantified using the Schoener’s D index, right: agglomerative hierarchical clustering UPGMA algorithm using niche overlap estimations. SA: Southern Andean distribution; CA: Central Andean distribution; SA-CA: Southern and Central Andean distribution.
