Coral communities of the Great Barrier Reef are facing multiple disturbances, in particular the coral-eating crown-of-thorns starfish Acanthaster planci (A. planci) that can occur as large-scale outbreaks. This project aims to provide innovative guidance in support of the management of A. planci, based on a metapopulation modelling framework broadly applicable to the control of marine pests. Expected outcomes include the identification of the environmental triggers of A. planci outbreaks; the identification of target reefs and critical thresholds of management intervention needed to limit the impact of A. planci under different climate and land use scenarios; and future forecasts of coral and fish biodiversity under these scenarios.

大堡礁的珊瑚群落正面临多重干扰，特别是以珊瑚为食的棘冠海星(Acanthaster Planci)，可作为大规模暴发发生。该项目旨在根据一个广泛适用于控制海洋有害生物的集合种群模型框架，提供创新的指导，以支持对Planci的管理。预期成果包括确定普氏假丝酵母菌暴发的环境触发因素；确定目标珊瑚礁和在不同气候和土地利用情况下限制普氏假丝酵母菌影响所需的管理干预的临界阈值；以及在这些情况下对珊瑚和鱼类生物多样性的未来预测。
