Fluctuating Asymmetry of Mandibles Characters of Macaca mulattain Taihang Mountains
摘要:
探讨太行山猕猴下颌骨波动不对称特征及影响因素.太行山猕猴下颌骨标本60例(♀42,♂18),按性别和年龄分组.选择下颌骨两侧对称的11个变量,转换为波动不对称值.结果显示下颌骨的波动不对称在性别组间和年龄组间没有明显的统计学差异(P>0.05);不同变量的波动不对称值不同;波动不对称的变化趋势是雌性大于雄性,亚成体组大于成年组.结果表明太行山猕猴下颌骨波动不对称特征与他们的肢骨不对称特征不同,在某种程度上反映了太行山猕猴早期生长发育和环境因素对下颌骨结构不对称的综合影响.
The fluctuating asymmetry (FA) of the mandible of Macaca rnulatta and the factors which likely influenced FA variation were investigated in the present study. A total of 60 mandible specimens were divided into four groups according to gender and age ( ♀ 42, ♂ 18). Eleven variables on both sides of the man/tible were selected, and were converted into FA val- ues. Results show that, totally, there were no significant differences in the asymmetry in these dimensions by age or sex groups. The FA values tended to be higher in female than in male, and tended to be higher in the sub-adults than the adults but their differences were not statistically significant (P^0.05). Results from this study suggested that the FA patterns of mandi- ble variables may be different from ones of their limb bones, and may reflect, to some degree, the plasticity in bilateral asym- metry with respect to genetic, environmental, and intrinsic developmental factors in Macaca mulatta.
