我们对两种猕猴的远端桡骨和胫骨的四个横截面进行了比较分析，以阐明骨形态与运动类型之间的关系。分别检查和比较雌性和雄性猕猴和束状猕猴的骨骼长度和每个部分的五种骨骼几何特性。在穆拉塔中，桡骨或胫骨不存在显着的性别差异。相比之下，雄性束状分枝杆菌的桡骨和胫骨在距远端 20% 和 40% 位置相对于距远端 5% 和 10% 位置的几何参数比雌性同类更大。穆拉塔的半径和胫骨相对于束状穆拉氏菌更长，穆拉塔的胫骨截面参数相对于束状穆拉氏菌更大。对物种间对数转换骨长度的标准化显示，束状分枝杆菌具有更大的径向皮质骨区域。相比之下，两个物种之间的胫骨皮质骨面积差异很小。这项研究表明，观察到的雌性和雄性束状分枝杆菌骨骼几何形状的差异可能是由于前臂和小腿肌肉重量的性别差异造成的，这可能是该物种雌性和雄性跳跃能力差异的基础。总而言之，这些种间比较的结果可能与以下事实有关：树栖灵长类动物（例如束状灵长类动物）在沿着倾斜的树干下降或向下桥接树缝时会因前肢引导而承受压缩机械应力，而陆生灵长类动物（例如穆拉塔灵长类动物）则在几乎平坦的基质上移动。从功能形态和运动类型方面讨论了两个物种之间前肢和后肢骨特性的差异。
We performed comparative analyses of four cross-sections of the distal radius and tibia in two species of macaque to clarify the relationships between bone morphology and locomotor type. The lengths of bones and five bone geometric properties in each section were examined and compared separately in both female and male Macaca mulatta and Macaca fascicularis. In M. mulatta, there were no significant gender-specific differences in either the radius or the tibia. In contrast, the radius and tibia of male M. fascicularis had greater geometric parameters in the 20% and 40% positions relative to the 5% and 10% positions from the distal end than those of their female counterparts. The radius and tibia of M. mulatta were relatively longer than those of M. fascicularis, and the sectional parameters of the tibia of M. mulatta were relatively larger than those of M. fascicularis. Standardization of the log-transformed bone length between the species revealed larger radial cortical bone areas in M. fascicularis. In contrast, there were minimal differences in the tibial cortical bone areas between the two species. This study suggests that the observed distinctions in bone geometry in female and male M. fascicularis may be due to gender-specific differences in the muscle weights of the forearm and calf, which may underlie the divergence in the leaping abilities of females and males of this species. Taken together, these results of interspecies comparisons may be related to the fact that arboreal primates such as M. fascicularis undergo compressive mechanical stress due to the forelimb lead that occurs as the animal descends a sloping trunk or bridges a tree gap downward, while terrestrial primates such as M. mulatta move on nearly flat substrates. Differences in fore- and hind-limb bone properties between the two species are discussed with regard to functional morphology and locomotor type.
