Abstract
The objective of this study was to survey non-volant mammals at Serra da Macaca Park Road (SP-139), particularly during road daily closure. Visual searches and camera traps were used to record mammals, and estimator Jackknife to estimate the expected richness. Differences in diversity were calculated using the Shannon-Wiener index (H’). In total, 12 species of non-volant mammals, four of them considered threatened, were sampled. Additionally, roadkills of the non-volant mammals were recorded too. The absence of some predominantly nocturnal species from the list of the roadkilled non-volant mammals was noticeable. The results highlight the importance of the temporary road closures, during periods of high mammal activity.
本研究的目的是调查Serra da Macaca公园路(SP-139)的非流浪哺乳动物，特别是在道路每日封闭期间。使用视觉搜索和相机陷阱来记录哺乳动物，并使用估计器Jackknife来估计预期的丰富度。利用Shannon-Wiener指数(H ')计算多样性差异。总共有12种非暴走性哺乳动物被取样，其中4种被认为受到威胁。此外，还记录了非自愿哺乳动物的道路死亡情况。值得注意的是，在道路死亡的非流浪哺乳动物名单中，没有一些主要的夜行动物。研究结果强调了在哺乳动物活动频繁期间临时封路的重要性。
