蚁蚁能够检测它们爬行的基质中的斜坡。据推测，身体主要部分之间和近端腿部部分之间的毛场有助于重力感受，从而触发响应基底坡度的姿势变化。研究并比较了两种蚂蚁在不同坡度上的矢状运动学。 Cataglyphis fortis 是一种北非沙漠蚂蚁，以其在质地几乎均匀的栖息地中具有非凡的方向感而闻名，而 Formica pratensis 是一种常见的中欧物种，主要使用地标和信息素痕迹进行定位。这两个物种的比较揭示了倾斜运动期间姿势适应的差异。仅观察到较小的与斜率相关的角度调整。最大的是 Cataglyphis 的头部旋转 25°，即使坡度改变了 150°，这表明视野发生了巨大的变化。两种物种的树干对坡度增加的俯仰调整都很低。在所有斜坡上，Cataglyphis 都能比 Formica 获得更高的奔跑速度，并且表现出更大的坡度相关的身高变化。这表明应对坡度变化的不同策略。这些具体方面必须反映在蚂蚁各自的坡度感知模式中。
Formicine ants are able to detect slopes in the substrates they crawl on. It was assumed that hair fields between the main segments of the body and between the proximal leg segments contribute to graviception which triggers a change of posture in response to substrate slopes. The sagittal kinematics of two ant species were investigated and compared on different slopes. Cataglyphis fortis, a North African desert ant, is well known for its extraordinary sense of orientation in texturally almost uniform habitats, while Formica pratensis, a common central-European species, primarily uses landmarks and pheromone traces for orientation. A comparison of these two species reveals differences in postural adaptations during inclined locomotion. Only minor slope-dependent angular adjustments were observed. The largest is a 25° head rotation for Cataglyphis, even if the slope is changed by 150°, suggesting dramatic changes in the field of vision. The trunk’s pitch adjustment towards the increasing slope is low in both species. On all slopes Cataglyphis achieves higher running speeds than Formica and displays greater slope-dependent variation in body height. This indicates different strategies for coping with changing slopes. These specific aspects have to be reflected in the ants’ respective mode of slope perception.
