Mitochondrial DNA Diversity of the Long-Tailed Macaque (Macaca fascicularis) from the Northern Region of Peninsular Malaysia

Abstract

We examined the genetic diversity of 64 long-tailed macaques from the northern states of Peninsular
Malaysia covering the states of Perlis and Kedah including the Langkawi Island using the complete
control region (CR) segment of the mitochondrial DNA. Standard genetic diversity including
nucleotide diversity, haplotype diversity and genetic divergence were calculated. Moderate nucleotide
diversity (π = 0.021) was observed which is higher than a previous study on the Penang M. fascicularis
population. Twenty-three haplotypes were detected with haplotype diversity, h of 0.936. Haplotype
sharing was observed among Langkawi and Perlis macaques indicating historical connection between
the island and the mainland. Phylogenetic trees constructed grouped the samples into 4 groups without
any obvious populations structuring.
