Long-term Site Fidelity and Individual Home Range Shifts in Lophocebus albigena

摘要: We investigated long-term site fidelity of gray-cheeked mangabey (Lophocebus albigena) groups in Kibale National Park, Uganda. Concurrently, we monitored shifts home range by individual females and subadult adult males. documented stability calculating the area overlap successive years, recording drift each group’s monthly centroid from its initial location. Home ranges remained stable for 3 our 4 (overlap over 10 yr >60%). Core areas were more labile, but group centroids drifted an average only 530 m entire decade. Deviations associated with dispersal or fission. During natal dispersal, males expanded their many months, settling ≤4 away. Adult males, contrast, typically dispersed within a few days to adjacent overlap. made solitary forays, nearly always into used current which they had previously belonged. After secondary ranging company new group, apparently without prior exploration area. Some also participated shifts. Females shifted social groups, association temporary permanent splits. Our observations raise possibility that male mangabeys use finder-joiner mechanism when moving during dispersal. Similarly, might learn resource locations immigrants before
