Abstract

We describe nine new polymorphic tetranucleotide microsatellite loci isolated from the fire-bellied toad (Bombina bombina). The relative yield of new loci was higher than described in previous studies in amphibians: out of 12 loci initially evaluated, nine were polymorphic and amplifying reliably. Number of alleles ranged from four to 10 and observed heterozygosities from 0.47 to 0.91. Seven loci were polymorphic also in Bombina variegata and five in Bombina orientalis. Enrichment protocols yielding long flanking regions potentially overcome difficulties (i.e, low yield of reliable loci relative to number of clones screened) which have been reported in microsatellite development in anurans.
