Fig. 3 Relationship between Δ CTI (the difference in CTI based on presence only data and CTI based on co-occurrence data) and Δ Elevation (the difference in average elevation for specimens of presence-only pseudo-plot and co-occurrence plots) in different calibrated models using the paired dataset. In the paired dataset, co-occurrence plots were matched with pseudo-plots by subsampling the latter and selecting the closest available pseudo-plot that had been sampled. The x-axis represents the elevational difference between presence-only and co-occurrence dataset. Here we used the 95th percentile of the paired dataset.
