Description ENMtools I and D values relative to the 95% confidence interval. Both of these metrics are measured from 0 (complete dissimilarity) to 1 (identity). I/D values that fall within the 95% C.I. (“in”) indicate models that are no more/less similar than random and are interpreted as evidence of niche conservatism. I/D values that fall above the 95% C.I. (“out, high”) and indicate statistical niche conservatism. I/D values that fall below the 95% C.I. (“out, low”) are interpreted as evidence of niche evolution.

Description Reclassified GARP models. Each figure shows the reclassified GARP models for each genus in each time-slice of each sequence. Note that GARP values indicate suitability and range from 0 to 100. See Supplemental Appendix 2 for explanation of the color values.

Title Supplemental Appendix 4

Description Original Maxent Models, Reclassified Maxent Models, and Geographic overlap analyses. Each figure shows the original Maxent model outputs in the left column, and the reclassification of that model to the right. The far right images are the final reclassified overlap analysis of the forward projected model and the original model of the next consecutive time slice. Model output values range from 0.0 to 1.0 and indicate probability. Final overlap calculation values indicate agreement, and range from 1 to 4. See Supplemental Appendix 2 for explanation of symbology.
