Résumé

While foraging, primates need to discriminate between edible and non-edible food and to identify what food allows them to meet their nutritional needs. Many primate species show a broad dietary breadth and considerable diet flexibility while others are more specialized in their feeding choices. Because the environment in which a species has evolved shapes many aspects of animal life, including in captive conditions, we aimed at investigating how dietary variability may influence food preferences in three monkey species living in semi-free ranging conditions at the Primate Centre of Strasbourg University. Preferences among eight different types of fruits were investigated via a two-alternative choice test in eight Tonkean macaques, seven capuchin monkeys and six long-tailed macaques. Those species live in tropical forests but have different dietary tendencies that may affect their food preferences. The more frugivorous species should prefer higher soluble sugar content than the more generalist species. Therefore, we expect a higher impact of fruit sugar content in Tonkean macaques' preference than in long-tailed macaques and capuchins. The latter will also be influenced by the relative content of protein and fat concurrently to that of sugar in the same fruit types. In comparison to the Tonkean macaques, these species may thus have a stronger preference for more nutritionally complete fruit since they include higher percentages of animal matter and seeds in their diet. Preliminary analyses of Tonkean macaques show a strong positive correlation between preference of fruit type and its total sugar content. For the other two species, results are being analyzed and will be discussed according to our comparative predictions. This study provides insights into the ecological and evolutionary adaptations of primates’ food choice.
