Table 2
Pearson's correlation coefficients (PCC) of Analysis (C). The bootstrap PCC; the mean of PCC calculated by 100 bootstrap iterations. The averaged PCC; PCC between the bootstrapped habitat suitability plots and the observed ratio of presence. The mean of both bootstrap PCC and averaged PCC were calculated.
