| 摘 要： | 通过分析采自珠江、鉴江、漠阳江、赣江、韩江、黄冈河、九龙江和闽江8个流域23个采样点121尾叉尾斗鱼mtDNA控制区3'端和临近序列共400bp,研究其种群遗传变异和亲缘地理格局。所分析序列只有13个变异位点,共有11个单倍型,碱基序列总的单倍型多样性为0.576,核苷酸多样性为0.00818,均较低。珠江流域存在群体内独有单倍型,有两个广布单倍型H1和H2,分别占所有样品的19%和62%。最小进化网络图显示单倍型没有明显的亲缘地理格局,呈星状发散,H1和H2处于中心。AMOVA分析显示变异主要来自地理区内群体间,歧点分布和中性检测显示叉尾斗鱼并未经历种群扩张。结果表明叉尾斗鱼种群遗传多样性很低且存在地理差异;各流域个体呈混杂分布格局,现有群体可能在珠江流域有东西两个起源;推测种群最近经历严重瓶颈效应。

| Abstract: | For their restricted distribution and strongly associate to evolutionary history and geological events,the freshwater fishe were usually used in biogeography studies.Macropodus opercularis(Perciformes,Belontiidae),a popular small freshwater ornamental fish,was originated in China from Yangtze basin to South China region including Hainan Island and Taiwan Island,and also could be founded in North Viet Nam.M.opercularis is an air breather,the male will build bubble nest and collect the fertilized eggs to the ... |
