A Sulawesi black-crested macaque (Macaca nigra) is foraging on a stream close to a beach in Tangkoko forest, North Sulawesi, Indonesia. The temperature increased in Tangkoko forest, and the overall fruit abundance decreased, according to a team of scientists led by Marine Joly, as published on International Journal of Primatology in July 2023 (accessed through Springer). "Between 2012 and 2020, temperatures increased by up to 0.2 degree Celsius per year in the forest, and the overall fruit abundance decreased by 1 percent per year, ” they wrote. A previous report by another team of scientists has revealed that approximately one-quarter of primates’ ranges in the world have temperatures over historical ones. Without climate change factor, Macaca nigra is still one of the 25 most endangered primates on earth, according to Macaca Nigra Project, an organization focusing on research and conservation of this endemic monkey species. Besides poaching (1, 700 traps have been collected in 16 years, they reported), the species is facing habitat loss and other kind of ecological threats caused by human activities. Macaca Nigra Project predicts that this species could be going extinct in 2050.
