ABSTRACT
The Red-cowled Cardinal (Paroaria dominicana) is an endemic passerine of the Caatinga biome in Brazil, and is one of the most traded passerines in the country. Illegal trade can have serious impacts on wild populations, such as reduced population sizes, the introduction of the species to areas outside their historical range or mixing individuals from different populations. Microsatellites constitute an important tool for population genetics and forensics studies, and hold great potential to help authorities manage illegal trafficking and inspect commercial breeders. We developed new microsatellite loci using massive parallel sequencing and characterized them in 23 seized Red-cowled Cardinals with unknown geographic origin. The DNA sequencing generated 2,068,684 paired-reads of which we identified 10,322 tri- to hexanucleotide loci. We selected 30 loci for amplification and polymorphism tests, of which 21 successfully amplified and 19 were polymorphic. The number of alleles ranged from 7 to 18 and the mean expected heterozygosity was 0.863. Six loci deviated from Hardy-Weinberg equilibrium probably due to null alleles and/or the Wahlund effect. Polymorphic loci in Hardy-Weinberg equilibrium showed low identity probability and high paternity exclusion probability. Our results indicate that this new set of microsatellite loci constitutes an important tool for both population genetic and forensic studies, with ultimate potential for assisting authorities in managing animal victims of illegal trafficking and the inspection of commercial breeders of the Red-cowled Cardinal.
