New set of microsatellite markers for the great-billed seed-finch (Sporophila maximiliani – Passeriformes: Thraupidae): tools for inspection and conservation

The Thraupidae family is one of the most wanted by bird breeders in Brazil due to its diverse, colorful and melodious singers as representatives. The Great-billed Seed-finch, Sporophila maximiliani, is the only representative of the genus Sporophila considered critically endangered in Brazil. Due to the demands of environmental agencies and of conservation programs, there is a need to increase the number of molecular markers available for the genus and specially for S.maximiliani. Therefore, this work aimed to provide a new set of microsatellite markers for S. maximiliani in order to help bird breeders and environmental agencies on fulfilling its demands as well as contributing with extra genetics tools for conservation programs of the Great-billed Seed-finch. Of the 30 markers developed, 25 successfully amplified and 22 were polymorphic. Annealing temperature varied from 52 to 64°C, number of alleles from two to 13 and the medium allele richness was 7.25 and medium expected and observe...
