A brownish baboon with a long mane and naked red rump, native to Ethiopia.
- ‘We also repeated some analyses with data from the researchers, who used foraging-group size for the gelada and hamadryas baboon.’
- ‘The current world population of geladas is estimated to be between 100,000-200,000, but subpopulations are isolated, and the species is listed by the United States Endangered Species Act as Threatened.’
- ‘Similar trends have also been observed for gelada baboons (Theropithecus gelada), in which altitude, which is highly correlated with ambient temperature, was found to correlate negatively with birth rate.’
- ‘The gelada (T. gelada) is the only cercopithecoid examined that retains the potential for exonization, while all Great Apes retain this potential.’
Mid 19th century: from Amharic č῾äallada.
