主导的查克马狒狒因低级群体成员的干扰而睡眠变差，这是首次有社会地位影响野生灵长类睡眠的证据。 Dominant chacma baboons sleep worse due to disturbances from lower-ranking troop members, first evidence of social rank affecting wild primate sleep.

《当前生物学》的一项新研究发现,在南非,由于低级部队成员夜间的干扰,占支配地位的Chacma baboons的睡眠质量较差,这是将社会等级与野生灵长类的睡眠模式联系起来的第一个证据。 A new study in Current Biology finds that dominant chacma baboons in South Africa experience poorer sleep quality due to nighttime disturbances from lower-ranking troop members, marking the first evidence linking social hierarchy to sleep patterns in wild primates. 研究人员利用GPS和加速度计项圈追踪野生狒狒，发现等级较高的狒狒更常被唤醒，可能是因为它们处于中心群体位置。 Researchers used GPS and accelerometer collars to track a wild troop, discovering higher-ranking baboons are more frequently awakened, likely due to their central group positions. 虽然目前尚不清楚这些干扰是否会影响长期健康，但研究结果表明，狒狒和人类一样，领导力可能伴随着夜间休息和恢复的代价。 While it’s unclear if these disruptions affect long-term health, the findings suggest leadership in baboons, like humans, may come with a nighttime cost to rest and recovery.
