Macaque à craché noir (Macaca nigra) de Sulawesi dans la réserve naturelle de Tangkoko, au nord de Sulawesi, en Indonésie. « Il y a des preuves de plus en plus nombreuses des effets négatifs des températures élevées sur le comportement, la physiologie, la reproduction et la survie de diverses espèces d'oiseaux, de mammifères et de reptiles dans le monde entier », a déclaré le Dr Nicholas Pattinson, un scientifique de l'Université du Cap, cité par Newsweek sur 5 mai 2022.

A Sulawesi black-crested macaque (Macaca nigra) in Tangkoko Nature Reserve, North Sulawesi, Indonesia. "There is rapidly growing evidence for the negative effects of high temperatures on the behavior, physiology, breeding, and survival of various bird, mammal, and reptile species around the world, " said Dr. Nicholas Pattinson, a scientist from University of Cape Town, as quoted by Newsweek on May 5, 2022._ Giving insight related to his own research on a hornbill species (the paper is available on Phys.Org), Pattinson added that "much of the public perception of the effects of the climate crisis is related to scenarios calculated for 2050 and beyond. Yet the effects of the climate crisis are current and can manifest not just within our lifetime, but even over a single decade."_ Regarding crested macaque and other world's primate species, additional climate-related knowledge is given by another scientist, Brogan M. Stewart. "Like humans, primates overheat and become dehydrated with continued physical activity in extremely hot weather, " he wrote in a 2021 article on The Conversation._ "In a warmer future, they would have to adjust, resting and staying in the shade during the hottest times of the day. This could mean foraging less or not mating, which could limit overall food intake and change reproductive cycles, " he added._ Sulawesi black-crested macaque is among the primates which are currently critically endangered in small habitats, while currently experiencing year-round temperatures above their historic thresholds, according to Stewart._ Around 25 years ago, Timothy O'Brien and Margaret Kinnaird had warned over climate change impact on Sulawesi crested macaque. "The climate change in every season influences the availability and distribution of foods that will change the primate's daily ranges and activities. These changes include food composition, feeding intensity, and range of foraging movement, " they wrote in International Journal of Primatology in 1997.
