Mitochondrial CO1 genetic structure among breeding sites of Chinese egret (Egretta eulophotes) in South Korea

Abstract Chinese egret ( Egretta eulophotes ) is classified as an endangered species (VU, vulnerable) and is limited to Far East. This species breeds especially offshore in China, Russia, and the Korean peninsula. We analyzed partial mitochondrial cytochrome c oxidase 1 of the bird from five major breeding sites in South Korea. The results indicate that there were only 10 mitochondrial cytochrome c oxidase 1 haplotypes and that their genetic diversity is very low. In addition, the distribution pattern of the haplotypes is patchy, indicating that at least a population may be distinct in its maternal origin and migration route. The results may be used as a baseline of establishing the conservation program and international cooperation for this species.
