Grooming directed to different body areas is likely to imply different costs and benefits for groomers and groomees. In this study, we investigated social influences on grooming topography in captive female mandrills (Mandrillus sphinx). Subordinate groomers preferred to direct grooming to "safe" areas (the back and rump) compared to dominant groomers, while subordinate groomees did not solicit preferentially grooming to safe areas. Groomers tended to initiate grooming episodes from safe areas, while groomees solicited the switch to unsafe areas. Our results highlight a previously unrecognized source of conflict between the partners of grooming, one of the most common cooperative interactions in animals.
针对不同身体部位的梳理行为可能对梳理者和被梳理者意味着不同的成本和收益。在本研究中，我们调查了圈养雌性山魈（Mandrillus sphinx）梳理行为模式中的社会影响因素。与占主导地位的梳理者相比，从属梳理者更倾向于将梳理行为指向“安全”区域（背部和臀部），而从属被梳理者并未优先寻求在安全区域接受梳理。梳理者倾向于从安全区域开始梳理过程，而被梳理者则会要求转移到不安全区域。我们的研究结果凸显了动物中最常见的合作互动之一——梳理行为中，伙伴之间此前未被认识到的冲突来源。
