The rivers and estuaries of northern Australia are highly productive environments, containing an exceptional diversity and abundance of large predatory aquatic species. This project aims to monitor the movements, habitat preferences and diet in eight large predatory species in a northern Queensland river over the next three years. Movement data will be combined with isotopic analysis to reveal how environmental and biological factors drive animal movements and impact habitat connectivity. In a world of vanishing top predators, it is imperative to understand system dynamics before we can evaluate the impact of species removal on ecosystem function.

澳大利亚北部的河流和河口是生产力极高的环境，拥有异常多样性和丰富的大型掠食性水生物种。该项目旨在监测未来三年昆士兰北部河流中八种大型掠食性物种的活动、栖息地偏好和饮食。运动数据将与同位素分析相结合，以揭示环境和生物因素如何驱动动物运动并影响栖息地的连通性。在顶级捕食者不断消失的世界中，我们必须先了解系统动力学，然后才能评估物种清除对生态系统功能的影响。
