Australia's giant Eucalypt trees are an amazing phenomenon and resource; underpinning unique ecosystems, rich in timber, stored carbon, and animal habitat. While tree height generally arises via an evolutionary arms race for light, the race has escalated dramatically in some locations and species. Using a computational framework that simulates adaptation driven by size-structured competition, this project will quantify how distinct factors-including climate, recruitment, and disturbance-enhance the race for light and can thereby explain the origins of Australia's giant Eucalypt. With calibrated models of species evolution, coupled with targeted fieldwork and big data, this project clarifies key forces shaping present and future vegetation.

澳大利亚巨大的桉树是一种令人惊叹的现象和资源；支撑着独特的生态系统，拥有丰富的木材、储存的碳和动物栖息地。虽然树高通常是通过光的进化军备竞赛而产生的，但在某些地点和物种中，这种竞赛已经急剧升级。该项目使用模拟大小结构竞争驱动的适应的计算框架，将量化气候、补充和干扰等不同因素如何增强对光的竞争，从而解释澳大利亚巨型桉树的起源。通过校准的物种进化模型，加上有针对性的实地考察和大数据，该项目阐明了塑造当前和未来植被的关键力量。
