Intercommunity competition in chimpanzees (Pan troglodytes) has been widely studied in eastern (P. t. schweinfurthii) and western (P. t. verus) communities. Both subspecies show hostility towards neighboring communities but differ in rates of lethal attacks and female involvement. However, relatively little is known about the territorial behavior of the two other subspecies, central (P. t. troglodytes) and Nigeria-Cameroon chimpanzees (P. t. ellioti). Here, we present the first insights into intercommunity interactions of individuals of a community of central chimpanzees living in the Loango National Park in Gabon. The presence of individuals of neighboring communities in the Rekambo home range was assessed using 27 camera traps. Information was compiled on intergroup interactions recorded before (2005–2016) and after (January 2017–June 2019) the habituation of the community. Individuals from neighboring communities entered the core area, where nine out of 16 recorded intercommunity encounters occurred. Males were the main participants in territorial patrols and intercommunity aggressions. Females were part of all six territorial patrols recorded and dependent offspring participated in five patrols. Females were involved in intercommunity aggression in five out of twelve recorded encounters in which there was visual contact between communities. While the intercommunity encounter rate was lower than that reported across most other long-term chimpanzee sites, the annual intercommunity killing rate was among the highest. These results suggest that the frequency of lethal attacks at Loango is comparable to that reported for the eastern subspecies. In contrast, female involvement in intercommunity interactions mirrors that of the western subspecies.

黑猩猩 ( Pan troglodytes ) 的群落间竞争已在东部 ( P. t. schweinfurthii ) 和西部 ( P. t. verus ) 群落中得到广泛研究。这两个亚种都对邻近社区表现出敌意，但致命袭击和女性参与的比率不同。然而，对于其他两个亚种，中央（ P. t. troglodytes）和尼日利亚-喀麦隆黑猩猩（P. t. ellioti ）的领地行为知之甚少。）。在这里，我们首次展示了居住在加蓬 Loango 国家公园的中央黑猩猩社区的个体之间的社区间互动。使用 27 个相机陷阱评估了 Rekambo 家庭范围内邻近社区的个人的存在。在社区习惯化之前（2005 年至 2016 年）和之后（2017 年 1 月至 2019 年 6 月）记录的群体间互动信息被汇编。来自邻近社区的个人进入了核心区域，记录的 16 次社区间相遇中有 9 次发生在该区域。男性是领土巡逻和社区间侵略的主要参与者。女性是记录的所有六次领土巡逻的一部分，受抚养的后代参加了五次巡逻。在有记录的社区之间有视觉接触的 12 次遭遇中，有 5 次是女性参与了社区间的攻击。虽然社区间遭遇率低于大多数其他长期黑猩猩栖息地的报告，但年度社区间杀戮率是最高的。这些结果表明，Loango 致命袭击的频率与东部亚种的报告相当。相比之下，女性参与社区间的互动反映了西方亚种的情况。这些结果表明，Loango 致命袭击的频率与东部亚种的报告相当。相比之下，女性参与社区间的互动反映了西方亚种的情况。这些结果表明，Loango 致命袭击的频率与东部亚种的报告相当。相比之下，女性参与社区间的互动反映了西方亚种的情况。
