Habitat selection patterns become more pronounced in older orangutans.

Relative probability of selection in 32 orangutans (n = 13 females, n = 19 males) as a function of orangutan age (six different scenarios for age, in y.o.) interacted with the distance to the FZS station (a, in meters), the distance to the nearest river (b, in meters), and elevation (c, in meters). The lines represent the average relative probability of selection as predicted by the resource selection function.
