This proposal aims to uncover the source reefs for Crown-of-Thorns Seastars (CoTS) outbreaks and the main routes of spread through the Great Barrier Reef. Coral eating CoTS pose a significant threat to the Great Barrier Reef. Using population genomics, invasive species genetics, and epidemiology and drawing upon extensive collections of adults and larvae dating from the 1980’s onwards, this project will test prominent hypotheses about outbreak origins and subsequent spatial spread of CoTS via larval dispersal. The project expects to clarify the locations and timing of long distance dispersal pathways and to test whether larval detection near reefs can provide an early warning for local outbreaks on these same reefs.

该提案旨在揭示棘冠海星（CoTS）爆发的源礁和通过大堡礁传播的主要途径。吃珊瑚的COTS对大堡礁构成了重大威胁。利用人口基因组学，入侵物种遗传学和流行病学，并借鉴从20世纪80年代起的成年人和幼虫的广泛收集，该项目将测试突出的假设爆发的起源和随后的空间传播CoTS通过幼虫扩散。该项目预计将澄清长距离传播途径的位置和时间，并测试珊瑚礁附近的幼虫检测是否可以为这些珊瑚礁的局部爆发提供早期预警。
