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).
