| nuclear introns help unravel the diversification history of the australo-pacific petroica robins. | australo-pacific petroica robins are known for their striking variability in sexual plumage coloration. molecular studies in recent years have revised the taxonomy of species and subspecies boundaries across the southwest pacific and new guinea. however, these studies have not been able to resolve phylogenetic relationships within petroica owing to limited sampling of the nuclear genome. here, we sequence five nuclear introns across all species for which fresh tissue was available. nuclear loci ... | 2019 | 30367975 |
