<![CDATA[The long-tailed macaque (Macaca fascicularis) is a primate species recognized for its exceptional ability to adapt to urban habitat. However, urban anthropogenic activities contribute to the fragmentation of macaque natural habitat, affecting genetic variation among distinct populations. Therefore, this study aimed to assess the genetic variability of M. fascicularis populations in Padang City, West Sumatra, Indonesia. A total of 70 fecal samples from the wild long-tailed macaques in Gunung Padang (GPD), Gunung Meru (GMR), and Gunung Pangilun (GPG) were collected using a non-invasive method. Conventional PCR amplification and Sanger sequencing were conducted to examine a 1,200-bp mitochondrial DNA (mtDNA) fragment in the D-loop region. The analysis of genetic variation showed that only two haplotypes were present in the three populations. Both GPD and GMR shared the same haplotype (H1), while the GPG population had a distinct haplotype (H2). No intrapopulation variation was observed, and haplotype differences were found in ten nucleotide sites with transition substitution mutations. These results showed limited genetic variation among populations of the long-tailed macaque in Padang, thereby providing valuable insights for stakeholders when formulating genetic conservation policies.]]>
