Isolation of polymorphic tetranucleotide microsatellite markers for the black-bellied seedcracker ( Pyrenestes ostrinus).

We have isolated 10 polymorphic microsatellite markers for the black-bellied seedcracker ( Pyrenestes ostrinus) from genomic libraries enriched either for (AAGG)n or (ATCT)n repetitive elements and characterized them in 39 individuals. The number of alleles ranged from two to 27 per locus with the observed heterozygosity ranging from 0.38 to 0.94. These markers will be useful for analysis of questions concerning parentage and population genetic structure. [ABSTRACT FROM AUTHOR]
