CANOPY FRUGIVORE GUILD
 BODY SIZE.-Eight species, all in the subfamily Stenoderminae of
the family Phyllostomatidae, constitute the canopy frugivore guild on
BCI. These eight species range from 8.1 to 69.3 g in mean body weight
(Table 1.). There is a mean increment of 1.44 between the body weights
of adjacently sized animals designated as fig specialists. Artibeus
