| hybridization between two recently diverged neotropical passerines: the pearly-bellied seedeater sporophila pileata, and the copper seedeater s. bouvreuil (aves, passeriformes, thraupidae). | the small neotropical finches called capuchinos are outstanding because they have experienced one of the most recent and explosive avian radiations ever documented for birds. despite very low morphological and niche divergence among species, many of them are reproductively isolated when in sympatry due to strong sexual selection in plumage traits. however, a specific pair of mostly parapatric species, the pearly-bellied, sporophila pileata, and the copper seedeaters, s. bouvreuil, has confounded ... | 2020 | 32218563 |
| isolation and characterization of microsatellite markers for conservation management of the endangered great-billed seed-finch, sporophila maximiliani (aves, passeriformes), and cross-amplification in other congeners. | the great-billed seed-finch, sporophila maximiliani, is a threatened neotropical bird that has declined mainly due to illegal trapping, with very few records in the wild in the last two decades. despite the existence of a considerable captive population that could be used for reintroductions into the wild, many individuals are known to be hybrids either with other species or subspecies of the genus. forensic investigations are urgently needed to distinguish between birds born in captivity from t ... | 2018 | 30232780 |
