(a) PCA biplot and loadings for the plot of PC1 against PC2 for Oreophrynella quelchii (WS = wind speed, WC = wind chill, TP = air temperature, RH = relative humidity, HI = heat index, BP = barometric pressure). (b) Mean probability of movement in Oreophrynella quelchii as a function of PC2 in the dry and wet seasons. Shaded areas are 95% confidence intervals. Dark points are observed data for individual toads. (c) Mean distance moved by O. quelchii as a function of PC2. (d) Mean distance moved by O. quelchii as a function of PC1 on vegetation and mud habitats. (e) Mean distance moved by O. quelchii in the dry and wet seasons for males and females. Error bars are 95% confidence intervals. Coloured points are observed data for individual toads
