Abstract Both invasive mesopredators and altered fire regimes impact populations of vulnerable native species. Understanding how these forces interact is critical for designing better conservation measures for endangered species. This study draws on Indigenous ecological knowledge and practice to explore heterogeneity in faunal responses to Indigenously managed landscapes in the Western Desert of Australia. Using track plot surveys and satellite image analysis of fire histories, we find evidence that pyrodiversity increases activity measures of dingoes and monitor lizards. Dingoes were more active in recently burnt patches, while foxes were more active in slightly older burnt patches. These results add to previous work showing significant effects of pyrodiversity on kangaroo populations in the region. Together, the findings suggest that Aboriginal burning not only creates diverse niches for native animals, it helps to facilitate the ecological role of species that are themselves functionally vital. This work adds to a growing body of research suggesting that the loss of Aboriginal burning can cascade through ecosystems by transforming and simplifying ecological networks, thus contributing to the decline and extinction of vulnerable species.

原住民焚烧促进了澳大利亚西部沙漠的精细高温多样性和本地捕食者

摘要 入侵性食肉动物和改变的火势都会影响脆弱的本地物种的种群。了解这些力量如何相互作用对于为濒危物种设计更好的保护措施至关重要。本研究利用土著生态知识和实践来探索动物群对澳大利亚西部沙漠土著管理景观的异质性。使用轨迹图调查和对火灾历史的卫星图像分析，我们发现有证据表明高温多样性增加了野狗和蜥蜴的活动量。野狗在最近被烧伤的斑块中更活跃，而狐狸在稍老的被烧斑块中更活跃。这些结果补充了先前的工作，表明热多样性对该地区的袋鼠种群产生了显着影响。一起，研究结果表明，原住民焚烧不仅为本地动物创造了多样化的生态位，还有助于促进本身在功能上至关重要的物种的生态作用。这项工作增加了越来越多的研究，表明土著燃烧的损失可以通过改变和简化生态网络在生态系统中级联，从而导致脆弱物种的减少和灭绝。
