Abstract

The skull morphology of ten genera of Philippine fruit bats was studied in relation to their nectar-feeding behavior, using six morphological variables. The included genera were Pteropus, Acerodon, Rousettus, Nyctimene, Ptenochirus, Harpiotavcteris, Haolonycteris, cynopterus, Eonycteris and Macro lossus. Based on multivariate analyses, cluster analysis and principal components analysis were found more reliable than discriminant analysis for establishing affinities between genera. The results indicated that of the ten genera, Eonvcteris-Macroglossus group of the subfamily Macroglossinae appeared to be more closely related with each other than the groups of Acerodon and Nyctimene, Ftenochirus and Eon ycjgrig; Harpionvcteris, Rousettus, and Cvnopterus; and Haplonvcteris and gyaggcerus. On the other hand, the results of discriminant analysis showed no overlapping between genera. However, the inferred relationships derived from the character analyses remain inconclusive and subject to further studies.
