Abstract

We assumed that Bukit Barisan as a physical barrier and its acts to population exchanges in West Sumatra, as well as for terrestrial animal group. If it does for bats in case for the Diadem Leaf-nosed Bat, Hipposideros diadema, which have superior dispersal powers to many other terrestrial group, then we might expect to see this some how reflected in morphological divergence. A total of 58 adult of H. diadema were collected directly using harp traps from several Cave in West Sumatra (Kalilawa Cave, Padang; Lereng Cave, Pariaman; (western of Bukit Barisan) and Salamaik Cave, Sawahlunto (eastern of Bukit Barisan)). The samples were collected on January-December 2013. Kruskall Wallis Test, Mann Whitney U Test, Principal Component Analyses (PCA) and Cluster Analyses demonstrated that these population could be separated clearly from one to another. This analyses based on 26 external and 15 skull measurement. The result showed that population of H. diadema from Salamaik Cave in Sawahlunto differ from H. diadema in Padang and Pariaman. Divergence characters among three population of H. diadema was found using Kruskall Wallis test. Mann-Whiney U test showed divergence characters between two different population. The result of PCA was congruence to phenogram obtained by UPGMA that showed close relationship between population of H. diadema from Kalilawa Cave, Padang to Lereng Cave, Pariaman and different from Salamaik Cave, Sawahlunto. We conclude that Bukit Barisan barriers could be affected to morphological divergence among H. diadema in West Sumatra.
