Abstract
The true frog species, Odorrana hosii, found in West Sumatera Indonesia, has high morphological differentiation and also estimated has high genetic variation. A total of 35 O. hosii at a seven location have analyzed using DNA microsatellite markers. Genetic variation of five microsatellite loci provided the highest value of expected heterozygosity (He) for the population in Padang (He = 0.618), while the lowest was the population in Merapi (He = 0.427). There are genetic differences in moderate levels among populations of O. hosii in West Sumatra (FST = 0.108) with inbreeding intrapopulation value (FIS = -0.559), and high value of gene flow among the populations (Nm = 2.061). This study becomes the first molecular data for establishing effective population management conservation.
Highlights
The distribution of Odorrana hosii is wide, from Thailand, Malay Peninsula, Sumatra, Java, to Borneo
This research aimed to analyze the genetic variation level of the O. hosii population in West Sumatra based on microsatellite markers
The parameters used to determine the genetic variation within a population were allele frequencies, the percentage of polymorphic loci (Pp), the average number of alleles per locus (Na), and expected heterozygosity (He)
Summary
The distribution of Odorrana hosii is wide, from Thailand, Malay Peninsula, Sumatra, Java, to Borneo. This species can live in an altitude interval from 300 masl to 1430 masl. Further research is necessary to examine the DNA level among O. hosii in West Sumatra to describe the species morphological variation that happens genetically. This research aimed to analyze the genetic variation level of the O. hosii population in West Sumatra based on microsatellite markers. The analysis of DNA variation using DNA microsatellite can determine the genetic differentiation of a frog population-based on geographical location with a range of 10 kilometers (Morgan et al, 2008)
