Fig. 4 – Functional diets of M. escalerai and M. crypticus depending on the nocturnal flight behaviour of the prey species, classified into non-volant (wingless arthropod groups), not actively-volant (able to fly but unlikely to have been captured through aerial hawking), nocturnally volant (likely to be captured by aerial hawking). Overall proportions of functional categories in the bat diets (a); proportion of not nocturnally volant prey items per dropping sample in M. escalerai and M. crypticus overall (b), in broad-scale allopatric versus sympatric regions (c) and in fine-scale locally allopatric versus locally sympatric locations (d). Star denotes significant differences between groups (Linear Model).
