... overlapping movement of proboscis monkeys in LBPMS suggests the existence of territorial behaviour among groups of proboscis monkeys as indicated by the high index of defensibility value (D). In this study, the D values of all focal groups were more than > 3, with KK (D = 4.56) and Owen (D = 4.61) being the most territorial for the one male units (OMU) and all male units (AMU), respectively (Table 2). ...Context 2
