Skull of the Asian (Paradoxurus Hermaphroditus) and the golden (Paradoxurus Zeylonensis) palm civet: Geometric morphometric analysis using palate, tooth and frontal landmarks

Abstract

This study aims to determine the differences in skull between Asian and golden palm civets by geometric morphometric method. The landmarks were marked on these photographs, and principal component, classical cluster and canonical variance analyses were performed. The method of geometric morphometry of the skull is a powerful tool used to differentiate the species. Fourteen and 20 homologous landmarks were marked using tpsutil and tpsdig2 programs on the frontal and palatinal directional photographs, respectively. As a result of the study, the first principal component (PC1) accounted for 33.586% on the frontal view, 41.602% on the palatinal view of the total shape differences, respectively. Distinctive differences on the frontal and palatinal view were observed in the caudal, rostrolateral and the last molars and the caudal palatine, respectively.
