Madagascar is an island nation renowned for its biodiversity and species endemism, yet it is still largely understudied despite intense anthropogenic threats including forest loss and edge effects. Anjanaharibe-Sud Special Reserve is a recently expanded rainforest protected area that is lacking detailed surveys and assessments of the native carnivore community of the endemic family Eupleridae. To identify which terrestrial carnivores occupy the reserve and what anthropogenic disturbances and factors best explain their occurrence patterns, we deployed 35 motionactivated cameras to detect native and introduced carnivores. From November 2018 to February 2019, we collected 2918 unique capture events (all species) and confirmed the presence of 5 euplerids: Galidia elegans, Galidictis fasciata, Eupleres goudotii, Fossa fossana, and Cryptoprocta ferox. These results extend the known range of E. goudotii and G. fasciata. In the reserve, F. fossana and G. elegans were the most common and widespread native carnivores, while E. goudotii was the rarest. We highlight the negative impact of edge effects on G. fasciata and F. fossana and the threat posed by the free-ranging non-native carnivore C. familiaris. This study represents the first detailed survey and occurrence estimates of the carnivore community of this protected area, allowing comparison with other protected areas in Madagascar. Our empirical findings show that anthropogenic disturbance negatively impacts carnivore existence within the Anjanaharibe-Sud Special Reserve and provide important management recommendations for protecting the carnivore community and the co-occurring wildlife living within this area.

马达加斯加最近扩大的热带雨林保护区 Anjanaharibe-Sud 特别保护区内受威胁的食肉动物群落评估

马达加斯加是一个以其生物多样性和物种特有现象而闻名的岛国，尽管存在严重的人为威胁，包括森林丧失和边缘效应，但它仍然在很大程度上未被充分研究。Anjanaharibe-Sud 特别保护区是最近扩大的热带雨林保护区，缺乏对地方性家族 Eupleridae 的本地食肉动物群落的详细调查和评估。为了确定哪些陆生食肉动物占据保护区以及哪些人为干扰和因素最能解释它们的发生模式，我们部署了 35 个运动激活相机来检测本地和引入的食肉动物。从 2018 年 11 月到 2019 年 2 月，我们收集了 2918 个独特的捕获事件（所有物种）并确认了 5 euplerids 的存在：Galidia elegans、Galidictis fasciata、Eupleres goudotii、Fossa fossana 和 Cryptoprocta ferox。这些结果扩展了 E. goudotii 和 G. fasciata 的已知范围。在保护区内，F. fossana 和 G. elegans 是最常见和分布最广的本土食肉动物，而 E. goudotii 是最稀有的。我们强调边缘效应对 G. fasciata 和 F. fossana 的负面影响以及自由放养的非本地食肉动物 C.familias 构成的威胁。这项研究代表了对该保护区食肉动物群落的首次详细调查和发生率估计，可以与马达加斯加的其他保护区进行比较。我们的实证研究结果表明，人为干扰对 Anjanaharibe-Sud 特别保护区内的食肉动物存在产生负面影响，并为保护食肉动物社区和生活在该地区的共生野生动物提供重要的管理建议。
