In many fishes, gender is influenced by environmental conditions experienced after hatching. However, the timing, cues, and developmental pathways of sex determination are poorly understood. This research will establish how environmental conditions during the juvenile phase control patterns of sex determination in reef fishes and determine if sex differentiation is a response to local- or broad-scale environmental cues. An individual's gender has profound and significant consequences for all aspects of its biology and the mechanism of sex determination has important implications for population ecology. This project will test theory in evolutionary ecology and greatly benefit the management of reef fisheries.

在许多鱼类中，性别受到孵化后所经历的环境条件的影响。然而，性别决定的时间，线索和发育途径知之甚少。这项研究将建立如何在青少年阶段的环境条件控制模式的珊瑚鱼的性别决定，并确定性别分化是一个响应本地或大规模的环境线索。一个个体的性别对其生物学的各个方面都有着深刻而重要的影响，性别决定机制对种群生态学有着重要的影响。这个项目将检验进化生态学的理论，并大大有利于珊瑚礁渔业的管理。
