Genetic diversity and genetic structure of the Daurian Partridge (Perdix dauuricae) in China, assessed by microsatellite variation

  • The Daurian Partridge (Perdix dauuricae) is a kind of hunting bird with high economic value. Genetic diversity and structure in the Daurian Partridge were studied by analyzing eight microsatellite loci in 23 populations found throughout the range of the species in China. The objectives were to evaluate the consequences on genetic diversity and differentiation of Daurian Partridge populations and to obtain a profound genetic insight for future management decisions and for effective measures to protect and exploit Daurian Partridges. The results showed that microsatellites were polymorphic in all Daurian Partridge populations, with a high level of genetic diversity over all the loci, especially in the Qaidam Basin populations which have the highest level of diversity. Significant genetic divergence was observed among different groups as well as between populations within the same group; most pairwise FST values were highly significant. Both phylogenetic trees and Bayesian clustering analyses revealed clear differentiation among the 23 populations of the Daurian Partridge, which were classified into two genetically differentiated groups. A bottleneck analysis indicated that Daurian Partridge populations have experienced a recent bottleneck. Our study argues that the Qaidam populations, North China populations, JN population, ZJC population, and Liupan Mountain populations should be paid special attention in order to retain adequate population sizes for maintaining genetic diversity.
