为什么不是所有的物种都存在？热带珊瑚礁鱼类物种边界的演化。实际上，在没有扩散障碍和栖息地不连续性的情况下，地理范围是如何在野外演变的，我们一无所知。该项目将利用数学模型和基于野外和实验室的进化模式和过程分析相结合的方法，调查大堡礁鱼类活动范围的演变。通过加深对物种范围限制的根本原因的理解，这项研究将为管理和保护这一非常宝贵的资源以及其他复杂的生物系统提供新的选择，在日益增加的开发、栖息地退化和气候变化的压力下。

Why aren't all species everywhere? The evolution of species' borders in tropical reef fishes. Virtually nothing is known about how geographic range limits evolve in the wild in the absence of barriers to dispersal and habitat discontinuities. This project will investigate the evolution of range limits of fishes on the Great Barrier Reef using combinations of mathematical modelling and field- and laboratory-based analyses of evolutionary patterns and processes. By advancing understanding of the fundamental causes of species' range limits, this research will provide new options for the management and conservation of this very valuable resource, and other complex biological systems, under increasing pressures of exploitation, habitat degradation and climate change.
