This project aims to determine how reef degradation modifies predator-prey dynamics in fish communities, and how parental effects may help species to cope with habitat change. Live corals are ecosystem engineers that support the world’s most biodiverse communities, but anthropogenic factors have led to unprecedented global declines in live coral. The transition from live to dead coral-dominated habitats is associated with a modified sensory landscape of fear for resident fishes, via chemical interference emanating from degraded coral. Inter-generational advantages would help management to regulate reef usage to promote resilience.

该项目旨在确定珊瑚礁退化如何改变鱼类群落中的捕食者-猎物动态，以及父母的影响如何帮助物种科普栖息地的变化。活珊瑚是支持世界上生物多样性最丰富的社区的生态系统工程师，但人为因素导致全球活珊瑚数量空前减少。从活珊瑚为主的栖息地到死珊瑚为主的栖息地的过渡与通过退化珊瑚产生的化学干扰对居民鱼类的恐惧感的改变有关。代际优势将有助于管理层规范珊瑚礁的使用，以提高复原力。
