Phylogeography-based delimitation of subspecies boundaries in the common pheasant (Phasianus colchicus).
To test the validity of subspecies status within the common pheasant (Phasianus colchicus), we used genetic data to assess differences among five subspecies distributed across the Loess Plateau in central China. Samples were collected from 191 individuals representing subspecies P. c. strauchi, P. c. satscheuensis, P. c. kiangsuensis, P. c. suehschanensis, and P. c. edzinensis. Analysis of mitochondrial genetic variation suggested that there were no phylogenetically distinct subspecies clades, and we could not exclude that hybridization has occurred among subspecies. A potential explanation of the observed pattern is that an increase in common pheasant rearing farms may have led to enforcement of hybridization between different subspecies. Consistent with phenotypic data, our analysis suggests that a previously identified common pheasant subspecies (P. c. strauchi) represents an intermediate form between the subspecies P. c. satscheuensis and P. c. suehschanensis.
