Barbary macaque and exclusion of monkeys from water sources are major causes of cedar bark stripping behaviour in Barbary macaques. Density of macaques, however, is less correlated with the behaviour than the other causes considered. The Barbary macaque was named by Carl Linnaeus in 1758, along with numerous other species named in that same year. The scientific name is "Macaca sylvanus". Phylogenetic and molecular analysis with other primates has been done. Studies concerning interspecific DNA variation within the genus "Macaca" show that the Barbary macaque is most related to the Asian macaques. Scientists have also studied the Y-chromosome; however, this has proven
Barbary macaque he should mate. This is further supported by the fact that male ejaculation peaks at the same time that female sexual swelling peaks. There is not a sufficient change in female sexual behaviour around the time of ovulation in order to demonstrate to the male that the female is fertile. The swellings, therefore, appear necessary for predicting fertility. Barbary macaque females differ from other non-human primates in that they often mate with a majority of the males in their social group. While females are active in choosing sexual associations, the mating behaviour of macaque social groups is not entirely determined
