Fig. 1. Least-squares regression of size-adjusted bite force (residuals of maximum bite force against head length) against gape angle during bilateral canine biting (slope=–1.51, r²=0.49, P=0.017). The dotted lines represent 95% confidence intervals. Each point represents a species mean: ¹Artibeus jamaicensis; ²Eidolon helvum; ³Pteropus vampyrus; ⁴Phyllostomus hastatus; ⁵Cynopterus brachyotis; ⁶Pteropus poliocephalus; ⁷Erophylla sezekorni; ⁸Carollia perspicillata; ⁹Monophyllus redmani; ¹⁰Glossophaga soricina; ¹¹Rousettus aegyptiacus.
