A growing body of research focuses on how anthropogenic factors affect the behavior and ecology of primates and their ecosystems. Infrastructural development, such as roads, is an increasingly pervasive anthropogenic impact that destroys primate habitat, affects the distribution and dispersal of primates, and facilitates human–primate interactions. At our field site in Bantimurung-Bulusaraung National Park, Sulawesi, Indonesia, a major road bisects the habitat of the endangered moor macaque (Macaca maura). Beginning in 2015, we observed a behavioral shift by our main study group: they began spending more time along the road foraging in trash pits and waiting for provisions from vehicles. Our objective in this study was to examine how access to anthropogenic foods has affected the group’s ranging behavior by comparing ranging data collected before (2010–2011) and after the shift (2016–2017). In contrast to what we expected, home ranges were significantly larger and daily travel distance was significantly longer after the shift compared to before. As predicted, mean distance to the road decreased after the shift. These results likely reflect the irregular and spatially dispersed nature of provisioning at this site. The macaques appear to be attracted to the road because it presents opportunities to obtain palatable and energy-dense foods. Our results indicate that moor macaques are able to flexibly adjust their ranging behavior in response to anthropogenic impacts. However, given the risks of being in proximity to roads and humans, management of this emerging human–macaque interface is needed.

越来越多的研究集中在人为因素如何影响灵长类动物及其生态系统的行为和生态上。基础设施建设，如道路，是一种日益普遍的人为影响，它破坏了灵长类动物的栖息地，影响了灵长类动物的分布和扩散，并促进了人与灵长类动物的互动。在我们位于印度尼西亚苏拉威西岛 Bantimurung-Bulusaraung 国家公园的野外现场，一条主要道路将濒临灭绝的沼泽猕猴 ( Macaca maura）。从 2015 年开始，我们观察到主要研究小组的行为发生了转变：他们开始花更多时间在路上在垃圾坑里觅食并等待车辆提供食物。我们在本研究中的目的是通过比较转变之前（2010-2011）和转变之后（2016-2017）收集的测距数据，来研究获取人为食物如何影响该群体的测距行为。与我们的预期相反，与之前相比，转变后的家庭范围明显更大，每日出行距离也明显更长。正如预测的那样，换班后到道路的平均距离减少了。这些结果可能反映了该站点供应的不规则和空间分散性质。猕猴似乎被这条路所吸引，因为它提供了获得美味和高能量食物的机会。我们的结果表明，沼泽猕猴能够灵活地调整它们的测距行为以应对人为影响。然而，考虑到靠近道路和人类的风险，需要管理这种新兴的人-猕猴界面。
