太行山猕猴锁骨性差研究

了解猕猴锁骨性差特征及影响因素.太行山猕猴锁骨和颅骨标本51例(雄:18,雌:33).选择锁骨11个变量.数据分析采用SPSS 19.0.用判别分析方法建立锁骨性别判别函数.单因素方差分析锁骨大多数变量性差显著(P<0.01).采用有关锁骨变量性别正确判别率较低(50.0%~76.5%).考虑到锁骨与颅长比值,性别正确判别率有所增加(80.4%~86.3%).整体上雌性判别率高于雄性,两侧之间没有明显差异.这种性差模式主要与锁骨特殊生长模式、形态结构、行为习性和种属特异性有关.

Sex Differences of Clavicles in Macaca Mulatta

To examine sex differences and the influencing factors of clavicles in Macaca mulatta,and the clavicles and skulls specimens were obtained from the 51skeletons of adult Macaca mulatta(♂18,♀33),and 11variables about clavicles were selected in this paper.SPSS 19.0was used for statistical analysis.The discriminant function analysis was used to establish clavicle gender discriminant function.For the one-way analysis of variance derived,most variables of clavicles showed highly significant sex differences(P<0.05or P<0.01).Only using variables of the clavicles,the accuracies of sex determination were low(50.0%-76.5%).However,using the relative sizes of the clavicles and cranial lengths,accuracies of sex determination became better(80.4%-86.3%).Overall,the female discrimination was higher than male's and there were no differences between the two sides.This sex differences were mainly related with special growth mode,morphology,behavior,habits and species specific of clavicle.
