摘要
探讨了太行山猕猴Macaca mulatta颅骨变量波动不对称特征及影响因素。猕猴颅骨标本62例(♀43,♂19),按性别和年龄分组。选择颅骨两侧对称的24个变量,转换为标准波动不对称值(FA)。数据用SPSS 20.0进行处理。结果显示:大部分颅骨变量的FA值在性别组间和年龄组间没有统计学差异(P>0.05);不同变量的FA值大小不同;FA值的变化趋势是雌性大于雄性,亚成体组大于成体组。结果提示猕猴颅骨波动不对称特征可能与它们的肢骨不对称特征不同,可能在某种程度上反映了猕猴的生长发育及环境刺激对不对称的影响。
The fluctuating asymmetry（ FA） of the skull of Macaca mulatta in Taihang Mountains and the factors which likely influenced FA variation were investigated in this study. The specimens of cranium consisting of sixty-two adult individuals,including nineteen males and forty-three females,were divided into groups according to gender and age,respectively.Twenty-four variables on both sides of the skull were measured and converted into values of FA. All the statistics were computed by SPSS 20. 0. The results showed that there was no significant difference of FA values among gender or ages. The values of FA tended to be higher in female than in male,and higher in the sub-adults than in the adults,however,their differences were not statistically significant（ P〈0. 05）. Results suggested that the fluctuating asymmetry patterns of skull variables may be different from ones of their limb bones,and may reflect,to some degree,the plasticity in bilateral asymmetry with respect to early developmental factors and environmental factors of M. mulatta.
