Regression analyses indicate a highly significant relationship between PSC accuracy ( cf . empirical species richness) versus wia ( F 1,8190 = 5615, adjusted R 2 = 0.4067, p < 2.2e−16; Figure 4a ), whilst the relationship weakens when positive (WIA) and uninfected (uWIA) predictions are combined ( F 1,8190 = 1933, adjusted R 2 = 0.1909, p < 2.2e−16; Figure 4b ).
