We present evidence of plasticity in habitat use and range extension of the striped hog-nosed skunk (Conepatus semistriatus) in Brazil. We first compiled literature records of C. semistriatus across its known distribution (N = 390), added new records from primary data (N = 10), and compared the main landscape composition (forest, savannah, grassland, agriculture) among these occurrence sites (N = 400). We unveil that landscape composition among occurrence sites varied widely within and among biomes in Brazil (Caatinga, Cerrado and Atlantic Forest), indicating C. semistriatus presence from dense forested habitats to grasslands and anthropogenic areas (especially agricultural landscapes). Almost 30% of the occurrence records of C. semistriatus are outside of the species known distribution, including records in ecotones between Cerrado-Amazonia biomes, extending its occurrence area in 449,118 km2. We conclude that habitat modification is a driver for the occurrence of C. semistriatus in dense forested habitats, facilitating its distribution expansion to previously unexpected areas.

巴西条纹猪鼻臭鼬 (Conepatus semistriatus) 灵活的栖息地利用和范围扩展

我们展示了巴西条纹猪鼻臭鼬 (Conepatus semistriatus) 在栖息地利用和范围扩展方面的可塑性证据。我们首先汇编了 C. semistriatus 已知分布 (N = 390) 的文献记录，从原始数据中添加了新记录 (N = 10)，并比较了这些发生地点的主要景观组成（森林、热带草原、草原、农业） (N = 400)。我们揭示了巴西（卡廷加、塞拉多和大西洋森林）生物群落内部和之间发生地点的景观组成差异很大，这表明从茂密的森林栖息地到草原和人为区域（尤其是农业景观），半纹状线虫的存在。近 30% 的 C. semistriatus 发生记录不在已知分布的物种范围内，包括塞拉多-亚马逊生物群落之间的交错带的记录，将其发生面积扩大到 449,118 平方公里。我们得出的结论是，栖息地的改变是在茂密的森林栖息地中 C. semistriatus 发生的驱动因素，促进了其分布扩展到以前意想不到的地区。
