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
Crab-eating macaque and "M. f. condorensis" is vulnerable. All other subspecies are listed as data deficient and need further study; although recent work is showing "M. f. aurea" and "M. f. karimondjawae" need increased protection. One concern for conservation is, in areas where "M. fascicularis" is not native, their populations need to be monitored and managed to reduce their impact on native flora and fauna. The genome of the crab-eating macaque has been sequenced. On 24 January 2018, scientists in China reported in the journal "Cell" the creation of two crab-eating macaque clones, named "Zhong Zhong and Hua Hua", using the complex
