Ranging behavior has been studied extensively in eastern (Pan troglodytes schweinfurthii) and western (P. t. verus) chimpanzees, but relatively little is known regarding home ranges of the other two subspecies (P. t. ellioti; P. t. troglodytes). In this study, we determined the home range size and space use of a habituated community (Rekambo) of central chimpanzees living in a habitat mosaic in Loango National Park, Gabon. Data on travel routes were collected during follows between January 2017 and April 2019 (N = 670,616 relocations, collected over 640 days and 5690 h of observation). We used three methods for calculating home range size (minimum convex polygon, kernel density estimation, and biased random bridges). We compare our estimates to those obtained from prior genetic and camera trap studies of the Rekambo community and contrast them with estimates from other chimpanzee communities of the four chimpanzee subspecies. Depending on the methodology used, the home range size of the Rekambo community ranged between 27.64 and 59.03 km². The location of the center of the home range remained relatively stable over the last decade, while the overall size decreased. The Rekambo home range is, therefore, one of the largest documented so far for chimpanzees outside savannah-woodland habitats. We discuss several explanations, including the presence of savannah, interspecies competition, and intercommunity interactions.

东部（ Pan troglodytes schweinfurthii）和西部（P. t. verus ）黑猩猩的测距行为已被广泛研究，但对于其他两个亚种（ P. t. ellioti；P. t. troglodytes）的活动范围知之甚少. 在这项研究中，我们确定了居住在加蓬 Loango 国家公园栖息地马赛克中的中央黑猩猩习惯社区 (Rekambo) 的家庭范围大小和空间使用。在 2017 年 1 月至 2019 年 4 月期间收集了有关旅行路线的数据（N = 670,616 次迁移，收集时间超过 640 天，观察时间为 5690 小时）。我们使用三种方法来计算家庭范围大小（最小凸多边形、核密度估计和有偏随机桥）。我们将我们的估计与先前对 Rekambo 群落的遗传和相机陷阱研究获得的估计进行比较，并将它们与四个黑猩猩亚种的其他黑猩猩群落的估计进行对比。根据所使用的方法，Rekambo 社区的家庭范围大小介于 27.64 和 59.03 km ^2之间. 在过去十年中，家庭范围中心的位置保持相对稳定，而整体规模有所下降。因此，Rekambo 栖息地是迄今为止记录在大草原-林地栖息地以外的最大黑猩猩栖息地之一。我们讨论了几种解释，包括大草原的存在、种间竞争和社区间的相互作用。
