摘　　要：记述了太行山猕猴掌骨和蹠骨的波动性不对称性(FA)特征.掌骨标本35例(雄8,雌27),蹠骨标本33例(雄8,雌25).选择变量5个,分别是掌骨和蹠骨最大长、中间宽、中间高、中间周长和中间横截面积.用SPSS13.0统计软件进行正态分布检验和波动性不对称的性差分析.研究结果表明:掌骨和蹠骨的5个变量FA值大部分不符合正态分布(P<0.05);掌骨和蹠骨FA值与身体大小相关性较弱;掌骨和蹠骨中间横截面积FA值相对较大,其他变量的FA值相对较小;FA值存在一定程度的性差.推测猕猴掌骨和蹠骨FA特征是种群水平上的,主要是遗传和出生前后环境因素作用的结果.In the paper,the fluctuating asymmetry（FA） in metacarpal and metatarsal dimensions of adult macaque（Macaca mulutta） from Taihang mountains has been surveyed.Osteological materials were obtained from 35 adult individuals,including 35 metacarpals and 33 metatarsals.Five dimensions,including metapodial length,dorsoventral diameter,mediolateral diameter,and circumference were measured at mid-shaft and metapodial midshaft cross-sectional area were calculated using the formula for an ellipse.Lilliefors tests,Shapiro-Wilk tests and independent-samples Mann-Whitney test adopting SPSS 13.0 for windows were used to determine the normality and sex differences of asymmetry.Results indicated that the FA scores of five dimensions in metacarpals and metatarsals in most instances deviated from normality and attained statistical significance at the P0.05 level.Analysis of correlation coefficients in most instances indicated that for no parameter does the association between body size and FA scores reach statistical significance in either sex.The mid-shaft area for the metacarpals and metatarsals showed relatively larger measurements,and other variables showed relatively smaller measurements.Sex differences in FA were also found in varying degrees.The results suggest that the traits of FA may be population-specific and mainly relate to the genetic component,testoterone levels and postnatal environment,such as mechanical loading and other important behaviors in primates.
