太行山猕猴掌面花纹密度的性别差异分析

Sexual Differences of the Palmar Density of Macaca Mulatta in Taihang Mountains

目的:研究太行山猕猴掌面的花纹密度(PD)的性别差异.材料与方法:运用SPSS 11.0 for Windows统计软件,对20只猕猴(10♂,10♀)的掌面7个主要花纹区,即近端小鱼际(HP)、远端小鱼际(HD)、大鱼际(TH)及指间4区(Ⅰ-Ⅳ)的花纹密度进行统计分析,用全模型法和逐步判别法建立判别函数.结果:掌面研究变量有7项变量在性别间有显著差异(P<0.05),6项变量达到极显著差异(P<0.01).两种方法的性别判别率均为90.0%.结论:掌面的花纹密度在两性之间有显著性差异,进行性别鉴别和功能推断有一定的实用价值和理论价值.

Objective： Studying the sexual differences of the palmar density of Macaca mulatta in the Taihang Mountains.Materials and Methods： Using SPSS 11.0 for Windows analysis of the palmar density variables which were obtained from the areas at seven primary pattern in palm of 20 Macaca mulatta （male： 10, female： 10）, viz. proximal hypothenar （HP）, distal hy-pothenal （HD）, thenar （TH） and inter-digital areas （I-IV）, two discriminably functions were established by means of Step-wise method and Enter independents. Results： The palmar variables showed that 7 variables were significant differences（P〈0.05）, and 6 variables were highly significant differences （P〈0.01）between the male and female; the discriminable rate for the two methods was 90.0% respectively. Conclusion： There were significant sexual differences in the palmar density of Macaca mulatta, so there are practical values and academic values in sexual distinguish and function illation.
