灵长类动物的位置行为为理解形态学、生态学和行为灵活性之间的关系提供了信息。从2005年9月到2006年8月，我们通过瞬时扫描取样法收集了中国西南部弄岗自然保护区黑叶猴的位置行为数据。我们预测，这些叶猴将使用（1）跳跃作为主要的运动模式和（2）两足站立在雨季比在旱季更频繁。结果表明，跳跃是最主要的运动方式（38.38%），其次是四足步行（31.2%）、垂直攀爬（25.1%）和四足跑步（5.3%）。地面是运动过程中最常使用的地层（33.4%）。大多数运动通过树木发生在小型（48.7%）和中型（47.6%）基板。运动模式，森林地层的使用和移动过程中的基板使用没有季节性变化。当静止时，坐姿是最常见的姿势（92.1%），其次是两足站立（3.7%）、躺着（3.5%）、四足站立（0.6%）、悬吊（0.2%）和仰卧（
Primates' positional behaviours provide information for understanding relationships among morphology, ecology and behavioural flexibility. From September 2005 to August 2006, we collected data via instantaneous scan sampling on positional behaviours in Francois' langurs at Nonggang Nature Reserve, south-west China. We predicted that these langurs would use (1) leaping as the predominant locomotor mode and (2) bipedal standing more frequently in the rainy season than in the dry season. Our result showed that leaping was the dominant locomotor mode (38.38%), followed by -quadrupedal walking (31.2%), vertical climbing (25.1%) and quadrupedal running (5.3%). The ground was the most frequently used stratum during movement (33.4%). Most locomotion through trees occurred on small- (48.7%) and medium-sized (47.6%) substrates. Locomotor mode, forest stratum use and substrate use during movement did not vary seasonally. When stationary, sitting was the most common posture (92.1%), followed by bipedal standing (3.7%), lying (3.5%), quadrupedal standing (0.6%), suspending (0.2%) and back-lying (
