| 摘 要： | 采用聚类分析、单因子方差分析和主成分分析方法,对4个不同地理群体大菱鲆进行了12项形态性状的测定,比较了4个群体的外部形态特征。聚类分析结果表明,4种大菱鲆群体中,丹麦和挪威之间及英国和法国之间的差异较小,丹麦、挪威和英国、法国之间的差异较大。方差分析多重比较结果表明,4个群体在部分形态特征上表现出明显差异,其中,英国和法国群体、挪威和丹麦群体之间形态特征差异显著指标较少,丹麦群体和英国群体、丹麦群体和法国群体、挪成群体和英国群体、挪威群体和法国群体之间差异显著指标较多。主成分分析构建了3个反映形态特征信息的综合性指标——主成分1、主成分2和主成分3,三者的贡献率分别为38.663%、14.117%和8.976%,三个主成分的累积贡献率为61.756%.分析结果显示,英国和法国群体、挪威和丹麦群体之间形态差异不显著,丹麦群体和英国群体、丹麦群体和法国群体、挪威群体和英国群体、挪威群体和法国群体之间形态差异显著,且差异主要来源于主成分1,而主成分1主要由经方差分析多重比较差异显著的指标组成,显然,主成分分析与聚类分析、方差分析的结论基本上是类似的,它们从不同的角度反映了群体间的形态学差异. |

| Abstract: | Statistic morphologic characters of four different populations of Scophthalmus maximus in Denmark,Nor- way,Britain,and France were revealed and compared on the basis of 12 morphological indices using hierarchical cluster, one-way ANOVA,and principal component analyses.The results show that among the four populations,the Danish and Norwegian are similar in morphology,so be the British and France ones.The Danish/Norway ones are quite different from Britain/France ones.One-way ANOVA analysis and multiple comparison have revealed also the same results.In principal component analysis,three principal components were constructed,the contributions from the first,second and third prin- cipal component were 38.663%,14.117% and 8.976%,respectively.The cumulative contribution rate was 61.756%.The results show that the morphological variations of Denmark-Norway population and Britain-France population are small but large in other pairs.Moreover,the discriminative variation comes mainly from the first component.Therefore,the 3 dif- ferent statistic methods on the morphology of the species demonstrated a consistent result that indicates the biological af- finity of the animal. |
