Isolation and characterization of 145 polymorphic microsatellite loci for the common frog (Rana temporaria).

We describe primers and polymerase chain reaction conditions to amplify 145 di-, tri- and tetranucleotide microsatellite loci from the common frog (Rana temporaria), a species commonly used as a model in ecological and evolutionary research. Primers were tested on 46 individuals from two Fennoscandian populations and yielded an average of six to nine alleles per locus (range = 1-30) depending on the population. Average observed heterozygosities in the two populations were 0.16 (range = 0-0.91) and 0.36 (range = 0-1).
