An international team of researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and the Félix Houphouët Boigny University in Abidjan, Ivory Coast were the first to explore an alternative way to gain insight into what nutritional aspects of natural food sources are important and preferred by wild foragers by combining analyses on the ranging patterns of wild chimpanzees. For this, the researchers followed five adult female chimpanzees from Taï National Park, Côte d’Ivoire, for more than 275 days and tested the relationship between the changes in travel direction that occurred on the chimpanzees daily travel paths and the nutritional aspects of the fruit species that they feed on and the trees’ characteristics. They found that chimpanzees were more likely to aim their travel towards fruit-bearing trees belonging to rare tree species and trees that provided fruits with high amounts of fat, sugar and fiber, such as nuts.
