| extreme mitogenomic divergence between two syntopic specimens of arremon aurantiirostris (aves: emberizidae) in central panama suggests possible cryptic species. | we report the complete mitochondrial genome of two specimens of orange-billed sparrow arremon aurantiirostris from colón province, in central panama. the two specimens were collected on the same day, and at the same locality; however, they showed substantial divergence (6.3% average pairwise divergence among coding genes). a survey of nd2 sequence variation across panama suggests that this divergence is the result of geographic differentiation and secondary contact. this high level of mitochondr ... | 2016 | 26367084 |
