Table 2.
Estimated range reduction and expansion based on differences between presD-CL and pastD-CL evaluated based on six thresholds. presD-CL is estimated present distribution using present climate and land cover data, and pastD-CL is estimated past distributions using past climate and land cover data. Mean of the area (M) and the percentage of difference (Δ) were calculated using 10 replicates. The area is the number of presence cells (1 km2) in pastD-CL.
