Document Summary
Lecture 6: behavioural implications of primate feeding ecology: the theory. Foraging = searching for, hand/processing, and actually eating food items. Field primatologists will often differentiate between foraging and feeding : feeding = actual consumption. Foraging and feeding can represent more than 50% of a primate"s activity pattern. Northern muriqui monkeys devote an average of about 50% of their feeding time to leaves. Female have to deal with the energetic costs of gestation and lactation, so food quality is important for them. High-quality foods are rich sources of digestible energy and protein. Low quality foods are low in nutrients, and could have higher levels of undigestible fibre. The limiting factors of food availability and quality on female reproduction, and access to females is the main limiting factor on male reproduction, female distribution in relation to food sources will affect male sociality. The silvery langur is a leaf-eating specialist found in south-east asia.
