Male bonnet macaques use information about third-party rank relationships to recruit allies

Article Abstract:

Male bonnet macaques, Macaca radiata, seem to use information about other males' dominance relationships. It was established that males selected allies that were of higher rank than themselves and their rivals much more frequently than anticipated if they chose allies randomly with regard to their relative rank. It is still not known how males mentally represent information about the rank of other males or what males know about other males' dominance ranks. For this reason, the possibility that there is a less cognitively generous reason for males' recruitment behaviour must not be rejected.

Effects of water availability and habitat quality on bark-stripping behavior in Barbary Macaques

Article Abstract:

Studies done on bark-stripping behavior in Barbary macaque in the Middle Atlas of Morocco between 1994 and 1996 that considered factors such as density of monkeys, livestock, and cedars; availability of water; and undergrowth quality is presented. Results reveal that the basic reason of the increase in bark-stripping behavior arises from a human exacerbated water scarcity in the cedar forest, rather than from densities of animals or competition with livestock for food resources in the undergrowth.
