RM2RW0FPT–A crested macaque (Macaca nigra) is photographed as it is about to jump while having an aggressive interaction with another individual in Tangkoko forest, North Sulawesi, Indonesia. Primatologists have found that fighting or chasing each other are part of crested macaque's social activities.

RM2RY5CMW–A Sulawesi crested-black macaque (Macaca nigra) shows a scream-like, wide opening mouth display, as it is pausing from foraging in Tangkoko forest, North Sulawesi, Indonesia. A recent report by a team of scientists led by Marine Joly revealed that the temperature is increasing in Tangkoko forest. '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 on International Journal of Primatology. 'In a warmer future, they (primates) would have to adjust, resting and staying in...
RM2RP9C96–Aggressive behaviors between young Sulawesi crested macaques (Macaca nigra) are photographed in Tangkoko forest, North Sulawesi, Indonesia. Primate scientists have found that fighting or chasing each others are part of crested macaque's social activities. Aggressive manual contacts occurred frequently and are very normal, and are often followed by retaliation and reconciliation--a fact that has helped building the reputation of crested macaque as a highly socially tolerant species. Meanwhile, climate change may reduce the habitat suitability of primate species, that could force them to move...
