Fig. 4: Home range estimations of North, South, and East groups.
From: Group-level cooperation in chimpanzees is shaped by strong social ties

Presented are the 95% (dashed lines) and 99% (solid lines) kernel home range utilization areas of North group (blue), South group (yellow), and East group (red). The 95% and 99% kernel home range sizes were 19 and 30 km2 in North, 38 and 49 km2 in South, and 32 and 43 km2 in East, respectively. The home range overlap at 99% Kernel was 1.3 km2 between North and South, and 15 km2 between South and East. There was no home range overlap between North and East.
