Habitat loss and fragmentation threat animal populations worldwide. Agriculture has changed the Cerrado’s landscape, in central Brazil, where native vegetation remnants are embedded in a non-natural matrix that can be resistant to animal movement. Felines, as carnivores, play an important ecosystem role as predators and are sensitive to habitat fragmentation. The long-term sustainability of small cat populations depends on the connectivity among natural remnants. The Emas National Park (ENP) is an important protected area located in the southwestern of the state of Goiás, a region highly modified by agriculture. We evaluated the landscape connectivity in the surrounding landscape of the ENP for small wildcats of the Cerrado; the margay, southern tiger cat, pampas cat, ocelot and the jaguarundi, based on their dispersal ability and habitat preferences. The habitat availability varied according to each species, the jaguarundi being the species with more habitat available and the margay with less. The ENP is important for the pampas cat and jaguarundi, and the Taquari River Sources State Park (TRSSP) is important for the ocelot, jaguarundi and for the southern tiger cat. The region is of great biological relevance and the lack of remnants around the ENP evidence failure in land management. The method used is a tool to identify priority fragments for conservation and management of the landscape for biodiversity.

排名巴西大草原上小野猫栖息地的重要性:景观连通性作为保护工具

生境的丧失和破碎威胁着全世界的动物种群。农业改变了巴西中部Cerrado的地貌,当地的植被残余被埋在可以抵抗动物运动的非自然基质中。猫科动物作为食肉动物,在捕食者中扮演着重要的生态系统角色,并且对栖息地的破碎非常敏感。小猫种群的长期可持续性取决于自然残留物之间的连通性。埃马斯国家公园(ENP)是位于戈亚斯州西南部的重要保护区,该地区受到农业的高度改造。我们评估了ENP周围环境中Cerrado小型野猫的景观连通性;玛格丽,南方虎猫,南美大草原猫,豹猫和美洲虎,基于它们的扩散能力和栖息地偏好。栖息地的可用性因每个物种而异,美洲虎是拥有更多栖息地的物种,而ga鱼则具有更少的栖息地。ENP对南美大草原猫和美洲虎猫很重要,而塔夸里河源州立公园(TRSSP)对豹猫,美洲虎和南部虎猫很重要。该地区具有重要的生物意义,ENP周围缺少残留物,这证明土地管理失败。所使用的方法是一种工具,用于识别优先片段,以保护和管理生物多样性景观。塔夸里河源州立公园(TRSSP)对于豹猫,美洲虎和南部虎猫来说很重要。该地区具有重要的生物意义,ENP周围缺少残留物,这证明土地管理失败。所使用的方法是一种工具,用于识别优先片段,以保护和管理生物多样性景观。塔夸里河源州立公园(TRSSP)对于豹猫,美洲虎和南部虎猫来说很重要。该地区具有重要的生物意义,ENP周围缺少残留物,这证明土地管理失败。所使用的方法是一种工具,用于识别优先片段,以保护和管理生物多样性景观。
