Phylogeography of Aplocheilus panchax in Indonesia, with special focus on the Bangka Island population

Abstract. Mustikasari D, Nuryanto A, Suryaningsih S. 2022. Phylogeography of Aplocheilus panchax in Indonesia, with special focus on the Bangka Island population. Biodiversitas 23: 2035-2046. Previous studies divided Blue panchax, into three different clades, namely West (W), Central (C), and East (E) clades. populations from Indonesia belong to However, that study did not include blue samples pits harsh conditions Island, Indonesia. Therefore, this aimed assess phylogeography a population using cytochrome c oxidase 1 (COI) gene. The results showed genetic distance within was less than 2%, while distances between other were ranged 103.87% 122.10%. There also clear gap populations, minimum 101.94%. Furthermore, seventy-nine sequences analyzed resulted 28 haplotypes variability 0.221 for nucleotide diversity (p), 0.923 Haplotype (Hd), 68.028 Fu’s Fs-test, 2.00 (P < 0.02) Fu Li’s D-test, 2.365 F-test; 1.927 Tajima's D test (0.10 > P 0.05). established distinct clade Western Eastern (E), (C) Molecular data is novel global phylogeographic.
