Genetic Characterization of Long-tailed Macaques (Macaca fascicularis) on Tabuan Island, Indonesia
Abstract
Protein and mitochondrial DNA variations (D-loop region PCR-RFLP) were analyzed for 7 serum and 40 clot samples collected from long-tailed macaques (Macaca fascicularis) living on Tabuan Island, Indonesia. Protein polymorphisms were examined electrophoretically for 5 and 12 kinds of protein in serum and erythrocytes, respectively. Each of the protein loci tested showed a monomorphic pattern. Polymorphisms were detected in the analysis of the D-loop-containing region of mtDNA (PCR-RFLP) using 32 restriction endonucleases. Two haplotypes, differing 1.03% in sequence divergence were observed, and both were previously undetected in other local populations. Based on genetic features and differences in pelage color as outlined in FOODEN'S (1995) morphological analysis, the present results suggest that long-tailed macaques on Tabuan Island are a unique population. From the genetic analyses performed here, Tabuan monkeys are considered to be the same species group as those populations of Sumatra and Java (FOODEN, 1995). Key Words: Protein variation; mtDNA PCR-RFLP; Macacafascicularis; Tabuan Island.
