高桥群体(0.661);遗传分化分析表明东、西群体分化极显著(Snn=0.970,P<0.001),Fst为0.315(P<0.001),Nm值为0.55;AMOVA分析揭示群体内变异程度高于群体间;NJ聚类分析均存在按照采样点聚类的现象。可见,湖栖鳍虾虎鱼的九龙山群体与高桥群体分化现象较明显。
In this study, we compared two Gobiopterus lacustris populations which from eastern and wesrern Leizhou Peninsula based on COI gene and D-loop region. The results were shown as follows : there were 29 variable sites in 619 bp COI sequences. The frequencies of T, C, A, and G were 27.8%, 31.0%, 23.7% and 17.5%, respectively.The haplotype diversity of Jiulongshan population(0.695) were higher than Gaoqiao population(0.324). Genetic differentiation analysis indicated that the eastern and western populations were differentiated significantly(Snn=0.591,0.01
