Two individuals of Sulawesi black crested macaque (Macaca nigra) in Tangkoko Nature Reserve, North Sulawesi, Indonesia._Climate change impacts on world's primates: Case of Sulawesi black-crested macaque (Macaca nigra)_"Story of the Frisky Yaki"_Since at least 1997, scientists have been examining the possible impacts of climate change to primates of the world, with results that it is changing their behaviors, activities, reproductive cycles, food availability and foraging range. Currently, approximately one-quarter of primates' ranges have temperatures over historical ones, as revealed by a team of scientists led by Miriam Plaza Pinto. Tangkoko forest, a sanctuary where crested macaque (Macaca nigra) lives, suffers from temperature increase by up to 0.2 degree Celsius per year, as reported by a team of primatologists led by Marine Joly after a long-time research, adding that the overall fruit abundance is also decreased. Another report suggests that changes related to seasons will indirectly affect the possibility of yaki, as the endemic macaque called by the locals, being infected by endoparasites._The habitat suitability of primate species is reduced, that could force them to move out of safe habitats and face more potential conflicts with human. At the same time, "unsustainable human activities are now the major force driving primate species to extinction, " a team of scientists led by Alejandro Estrada added in their 2017 paper published on ScienceAdvances. Primates of the world have already suffered from the escalating anthropogenic pressures, causing up to 93% species to have declining population and around 68% to enter the extinction risk. Two wild, habituated crested macaque groups in Tangkoko forest often occupy the tourist zone, according to a team of primatologists led by Dominique A. Bertrand in their September 2023 paper published on Researchgate.
