Increasing urbanization and consequent habitat fragmentation and loss call for studies of the influence of urbanization on native fauna. South American Coati (Procyonidae: Nasua nasua) live in groups and are common in urban areas of South America. Here, we aimed to understand how coatis occupy and select space, and whether they change their circadian activity in an urban environment. We estimated home range sizes, verified any overlap, and evaluated the effects of sex and weight on home range size. We also described coati activity patterns associated with habitat selection. Animals established their home ranges only within the study area, with few exploratory exits to surrounding areas. Furthermore, our home range estimates of 0.66 km2 are lower than previously found in natural habitats. We did not observe an effect of sex or weight on home range size. Coatis predominantly selected forested areas and explored houses only early in the morning. We suggest that this demonstrates the need for forested areas for survival of the species. Regarding activity patterns, coatis were active only during the day, as described for the species in its natural environment. Human barriers—in addition to human refuse that serves as food—could reduce the home range sizes. Our data demonstrate differences in home range size, but not circadian activity or habitat selection when compared to coatis in their natural environment.

城市景观如何影响南美长鼻浣熊（Nasua nasua）的时空生态？

日益增长的城市化以及随之而来的栖息地破碎和丧失需要研究城市化对本土动物的影响。南美浣熊（浣熊科：Nasua nasua）群居，常见于南美洲城市地区。在这里，我们的目的是了解长鼻浣熊如何占据和选择空间，以及它们在城市环境中是否改变昼夜节律活动。我们估计了活动范围的大小，验证了任何重叠，并评估了性别和体重对活动范围大小的影响。我们还描述了与栖息地选择相关的浣熊活动模式。动物仅在研究区域内建立它们的栖息地，很少探索性地离开周围区域。此外，我们估计的栖息地范围为 0.66 平方公里，低于之前在自然栖息地发现的范围。我们没有观察到性别或体重对活动范围大小的影响。长鼻浣熊主要选择森林地区，只在清晨探索​​房屋。我们认为这表明该物种的生存需要森林地区。关于活动模式，长鼻浣熊只在白天活动，正如该物种在自然环境中所描述的那样。人类障碍——除了作为食物的人类垃圾之外——可能会减少家庭活动范围的大小。我们的数据显示了与长鼻浣熊在自然环境中相比，其活动范围大小存在差异，但昼夜节律活动或栖息地选择没有差异。
