Correlation between the reference and partial models.a

Area tested for correlation, data excluded from the model generation	Presences	Reference IDW vs. Partial IDW	Reference Maxent vs. Partial Maxent
Area 1	492	−0.2099	0.9888
Area 2	484	−0.0659	0.6564
Area 3	426	−0.325	0.4504
Area 4	523	−0.0558	0.9954

^aThe reference models were generated using all of the presence data. For each partial model, the presences of the corresponding area were removed, and that window area was then used for the correlation calculation. The correlation between the reference IDW and Maxent models for the entire Iberian Peninsula was 0.1542. Areas as in Figure 1.
