Figure 2.

Schema used to record individuals' spatial position. The scale of this schema is 1 m². Circles, ellipses, and polygons represent trees and bushes where the mandrill could get covered. The line on the upper side represents the beginning of the forest area. The feeding zone is contained to X = 12–15 and Y = 0–4 and the door is represented by the polygon in X = 5–6 and Y = 3–4. The two circular buffers are characterized by the 10 m (blue) and the 20 m (red) areas used to calculate frequencies of observation.
