太行山猕猴牙齿与颅长的相关性

Correlation between Dental Variables and Cranial Length of Macaca mulatta in Taihang Mountains

对太行山猕猴牙齿有关变量做了测量、统计 ,并就其与颅骨长间的异速生长和相关程度进行了研究。结果表明 ,太行山猕猴牙齿具有明显的性别差异 ,雄性牙齿的变异程度在犬齿和中央门齿表现尤为突出。在线性型或面积方面 ,雄性牙齿的异速生长均快于雌性和雄 +雌 ,此与其生活史对策相适应。在雄性、雌性或雄 +雌 ,下颌齿变量与颅骨长的相关程度比上颌更为密切。与有关资料的比较表明 。

The allometric analysis and the research of correlation degree between tooth and cranial length Macaca mulatta in Taihang Mountains has been carried out by survey and statistics. The result shows that there are evidently sexual difference of tooth variables in male and female; the variation degree of canine and central incisor of male is significant. The allometric speeds of dental variables are faster in male than in female and male+female,no matter what the life strategy is. The correlation degree between mandibular tooth dimensions and cranial length is closer than in maxilla regardless of male, female or male+female.This paper also gives a comparison among Macaca mulatta tcheliensis in Taihang Mountains and Rhinopithecus spp. and Presbytis phayrei. The result indicates that the difference between Macaca mulatta and Rhinopithecus spp. is smaller than that in the Macaca mulatta and Presbytis Phayrei.
