北部湾沿海西施舌不同地理群体形态差异研究
Morphological variation analysis of different geographical populations of Coelomactra antiquata along the coast of Beibu Gulf
摘要
Abstract
To compare the morphological differences of four wild populations of Coelomactra antiquata from Beihai,Dongxing,Fangchenggang and Zhanjiang along the coast of Beibu Gulf,five statistical analysis methods were used to analyze,including morphological indicator variation analysis,one-way analysis of variance(ANOVA),cluster analysis,principal component analysis(PCA)and discriminant analysis.The results showed that the convexity of the shell was determined by the width and anterior edge of the shell,and the weight of the shell is an indirect indicator of the thickness of the shell.The cluster analysis results showed that the four groups formed two clusters.The first cluster was formed by the Beihai,Fangchenggang and Dongxing groups,while the Zhanjiang group formed a separate cluster.Three principal components were obtained by PCA,of which the contribution rate of the first principal component of 4 groups was 38.30%,the second principal component was 25.64%,the third principal component was 13.44%,and the cumulative contribution rate was 77.38%.The dis-criminant accuracy of P1 for the four C.antiquata groups ranged from 81.25%to 96.87%,while the discriminant accuracy for P2 was 74.29%-100%,and the comprehensive discriminant rate was 88.10%.These characteristics indicated that the morphological variation of the C.antiquata populations in Beihai,Fangchenggang and Dongxing was relatively small,while that in the Zhanjiang population was large.关键词
