Body Size Predicts Echolocation Call Peak Frequency Better than Gape Height in Vespertilionid Bats
Abstract In most vocalizing vertebrates, lighter animals tend to produce acoustic signals of higher frequency than heavier animals. Two hypotheses propose to explain this negative relationship in vespertilionid bats: (i) mass-signal frequency allometry and (ii) emitter-limited (maximum gape) signal...
