This project aims to utilise a unique Australian model system based on multiple, independently-evolved subterranean water beetles to explore the adaptive and regressive changes in the genome that occur when surface species colonise subterranean habitats. This project focuses on the evolution of Heat Shock protein (Hsp) genes that play critical roles in adaptation to environmental stress and the process of de-canalisation, the release of cryptic genetic variation that can allow novel morphologies to evolve in new environments. The project expects to provide further understanding of how species may potentially adapt to environmental stresses in the future, including climate change.

该项目旨在利用基于多种独立进化的地下甲虫的独特的澳大利亚模式系统来探索当表层物种定居在地下栖息地时基因组的适应性和倒退变化。这个项目的重点是热休克蛋白(HSP)基因的进化，这些基因在适应环境压力和去角化过程中发挥关键作用，去角化过程是释放隐蔽的遗传变异，使新的形态能够在新的环境中进化。该项目希望进一步了解物种可能如何适应未来的环境压力，包括气候变化。
