应用形态度量学方法对中华纹胸鮡和福建纹胸鮡物种有效性的研究

Study on Species Validation for Glyptothorax sinense (Regan) and G. fukiensis (Rendahl) with the Method of Morphometrics

采用形态度量学方法对分布于长江、珠江、九龙江、海南岛和闽江的福建纹胸和中华纹胸 12 6个个体框架结构测量中的 2 3个指标进行了主成分分析 ,以探求中华纹胸和福建纹胸的物种有效性。初步研究结果表明各样本贡献值较大的前 4个主成分在数值上并没有明显的差异。显然 ,以上 2个物种在形态上并没有明显的区别 ,福建纹胸应为中华纹胸的同物异名 。

To explore the species validation of Glyptothorax sinense (Regan) and G. fukiensis (Rendahl), a principle analysis was conducted on 23 measurements of truss networks in 126 individuals collected from Yangtze River, Pearl River, Jiulongjiang River, Hainan Island and Minjiang River using the method of morphometrics. The preliminary analysis result indicates that among the first four principle components there is no prominent difference. Therefore,it should be regarded that the two species have no prominent difference in morphology and G. fikiensis should be considered as the synonyms of G. sinense .\;
