Friends and food...how does an artificial termite mound affect the social behavior of gorilla groups?

Behavioral and spatial data will be collected for 5 hours daily on the family group (n=10) of Western lowland gorillas at Zoo Atlanta. Every 2-3 minutes, data collectors will plot the spatial location of each gorilla on an electronic map, via Apple iPads(TM). Simultaneously, continuous behavioral data concerning aggressive or affiliation behaviors between individual gorillas will also be recorded. This information will be compared within and between individual gorillas, but also before and after the installation of the artificial termite mound.
