Abstract: Though it has been long presumed that peripheral populations tend to exhibit low levels of genetic diversity due to isolation and genetic drift, results of empirical investigation remain ambiguous. Some rusty-necklaced partridge (Alectoris magna) populations have expanded their present ranges, resulting in several peripheral populations, due to recent deforestation by human beings in Northwestern China. On the basis of mitochondrial DNA control-region and microsatellite DNA data, we compare the genetic diversity (phi-, H-, H0-, and HE-values) between three peripheral populations and five central populations. Maternal and biparental DNA markers indicated accordantly genetic diversity. Compared to central populations, the peripheral populations exhibited lower genetic diversity. The low genetic variability of the three peripheral populations appeared to result partly from isolation and natural selection.
