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.
