Log transformed relative forelimb length regressed on maximum latitude. The figure shows the association between relative forelimb length and latitude in Pteropodidae. AICc-θAICc denotes the difference in AIC between the shown adaption model and the intercept-only model, and r 2 denotes the amount of variation in relative limb length explained by maximum latitude (optimal regression). The evolutionary regression (solid line) represents the observed relationship between relative forelimb length and maximum latitude, whereas the optimal regression is adjusted for the effect of phylogenetic inertia
