Isolation and development of microsatellite markers for the brazilian cerrado endemic tree frog Ololygon centralis (Anura: Hylidae)

Abstract

The aim of this study was to develop microsatellite markers for Ololygon centralis, an endemic tree frog species of the Cerrado biome of Brazil, to improve population genetics studies with focus on conservation and ecology. Sets of primers were designed from sequences derived from high throughput sequencing (Illumina-Miseq). Five polymorphic microsatellite loci were characterized for 30 individuals from three populations of the state of Goiás, Brazil. All loci combined presented a probability of identity (I) equal to 1.13x10-6 and paternity exclusion (Q) of 0.993. The number of alleles per locus ranged from 5 to 17, with a mean of 10 alleles. The expected and observed heterozygosity ranged from 0.41 to 0.98 and from 0 to 1, respectively. The global fixation index Fst found was 0.213 (P < 0.05). These markers will be useful for genetic diversity analysis and will contribute to population genetics studies for species of the Scinax (=Ololygon) catharinae clade.
