Haplotype analysis of long-tailed macaques in TNB Bukit Selambau, Peninsular Malaysia, leads to inferences of fission-fusion social structure

Long-tailed macaques have been roaming near Tenaga National Berhad Bukit Selambau Solar (TBSS) causing human–macaque conflicts. This study reveals the social organization and genetic variation of these macaques. Macaques’ groups were determined via direct observation and closed-circuit television. Genomic DNA from 29 fecal samples were extracted and proceeded with amplification of the D-loop region of mitochondrial DNA. There are four main groups of primates at TBSS. Some members of the Kuil group and the Pekan group shared haplotype 1, forming a fission-fusion society. This finding can be used for TNB in mitigation plan involving human–macaque conflict.
