| Abstract |
The hazel grouse is distributed throughout much of northern Asia and Europe, whereas the closely related Chinese grouse is endemic to central China. The molecular phylogeny of these two species was an...alyzed using a 420 bp segment of mitochondrial DNA control region domain I. We analyzed a total of 201 samples of hazel grouse collected from Hokkaido to Europe and 11 samples of the Chinese grouse collected in China. In total, 79 and 7 haplotypes were found for the hazel grouse and the Chinese grouse, respectively The phylogenetic tree showed a clear separation of the hazel grouse cluster from the Chinese grouse cluster. Two haplotypes from Italy (n =1) and the Southern Alps (R= 1) in Switzerland (Tessin) were clearly clustered and distinctly separated from the other hazel grouse haplotypes cluster. Two haplotypes from northern part of the population were separated from the southern part of the population. These observations indicate that the Chinese grouse and hazel grouse were separated at least 200,000 years ago and the southern Alps population separated from the other hazel grouse at least 100,000 years ago. These three grouse populations reached their present distribution during the last several ten thousand years.show more
