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
Japanese macaque The macaque has other unusual behaviours, including bathing together in hot springs and rolling snowballs for fun. Also, in recent studies, the Japanese macaque has been found to develop different accents, like humans. Macaques in areas separated by only a few hundred miles can have very different pitches in their calls, their form of communication. The Japanese macaque has been involved in many studies concerning neuroscience and also is used in drug testing. The Japanese macaque is diurnal. In colder areas, from autumn to early winter, macaques feed in between different activities. In the winter, macaques have two to four
