| 摘 要： | 应用聚类分析、主成分分析和判别分析3种分析方法,通过测量彩虹明樱蛤的10个形态学比例性状,对来自海州湾连云港海区(LYG)和杭州湾南岸慈溪海区(CX)以及杭州湾北岸的平湖乍浦海区(ZP)3群体彩虹明樱蛤的形态差异进行了比较研究。聚类分析表明,海州湾群体与杭州湾群体形态差异最大,连云港与杭州湾的慈溪群体和乍浦2群体形态距离分别达到了4.92和5.58,而杭州湾慈溪群体和乍浦群体形态最为相似,形态距离仅为2.16。主成分分析构建了2个主成分,其贡献率:主成分1为54.40%,主成分2为13.50%,累积贡献率为67.90%;两个主成分的累积贡献率较高,这些因子主要是第1主成分中的性状AB、AD、AB、SW、EF、GH、AI和IJ以及主成分2中的AE。判别分析结果表明,3个海区群体之间的形态差异极显著(P<0.01);经6步判别分析后应用AF、IJ、AE、AB、SW和GH建立的判别函数,其判别准确率P1为80%~100%,P2为82.86%~100%,综合判别率为88.89%,说明判别方程可以有效的将上述群体区分开来。

| Abstract: | The morphological variations in ten morphometrical characters were evaluated among three geographical populations of clam Moerella iridescens,Lianyungang(LYG)from Hangzhou bay,Zhapu(ZP)and CiXi(CX)from Haizhou bay by cluster analysis,principal component analysis and discriminant analysis.The cluster analysis revealed that there were similar morphological traits between CiXi and Zhapu populations(morphological distance 2.16),but quite different from that of Lianyungang(morphological distance 4.92 and 5.58,re... |
