种内竞争是许多物种形成空间利用策略和运动决策的关键因素，但邻居如何以及何时利用共享区域，同时表现出积极的相互回避在很大程度上是未知的。在这里，我们调查了时间景观分区的野生狒狒（Papio cynocephalus）的人口。我们使用全球定位系统（GPS）项圈同步记录5狒狒社会群体的每小时位置约900天，我们使用的行为，人口和生活史数据来衡量影响重叠区域使用的因素。邻近群体的年度活动范围基本上重叠，正如预测的那样（狒狒被认为是非领土性的），但在较短的时间尺度上评估空间利用时，活动范围重叠较少。此外，相邻群体在空间上彼此接近的天数比零模型预测的少，这表明了一种基于回避的空间分布模式。在所有的时间尺度检查（每月，每两周和每周），在重叠地区花费的时间更大的时间段，当组均匀分散，低质量的食物喂养。社会群体中育龄女性的百分比与仅在每周时间间隔内在重叠区域花费的时间呈负相关。这表明，广泛的时间变化的生态资源是一个主要的预测如何密集重叠的地区使用，和群体修改这些生态驱动的间隔模式在短时间尺度上的基础上，女性生殖状态。这些研究结果一起提供了深入了解经济学的领土，突出的动态空间模式在不同的时间尺度。
Intraspecific competition is a key factor shaping space-use strategies and movement decisions in many species, yet how and when neighbors utilize shared areas while exhibiting active avoidance of one another is largely unknown. Here we investigated temporal landscape partitioning in a population of wild baboons (Papio cynocephalus). We used global positioning system (GPS) collars to synchronously record the hourly locations of 5 baboon social groups for ~900 days, and we used behavioral, demographic, and life history data to measure factors affecting use of overlap areas. Annual home ranges of neighboring groups overlapped substantially, as predicted (baboons are considered non-territorial), but home ranges overlapped less when space use was assessed over shorter time scales. Moreover, neighboring groups were in close spatial proximity to one another on fewer days than predicted by a null model, suggesting an avoidance-based spacing pattern. At all time scales examined (monthly, biweekly, and weekly), time spent in overlap areas was greater during time periods when groups fed on evenly dispersed, low-quality foods. The percent of fertile females in social groups was negatively correlated with time spent in overlap areas only during weekly time intervals. This suggests that broad temporal changes in ecological resources are a major predictor of how intensively overlap areas are used, and groups modify these ecologically driven spacing patterns at short time scales based on female reproductive status. Together these findings offer insight into the economics of territoriality by highlighting the dynamics of spacing patterns at differing time scales.
