Of all the climatic factors determining species distributions, temperature is arguably the most important. It is extremes – rather than averages – that drive species evolution. So it is concerning that although extreme temperature events are increasing in frequency and intensity little is known about the breadth of thermal tolerance of plants from extreme environments. This information is crucial to understand species distribution and survival under future climate regimes. This project will ascertain the thermal breadth of Australian species growing in situ and under controlled environments. The project will contribute to development of effective conservation, restoration and rehabilitation plans for Australian native plant communities.

在决定物种分布的所有气候因素中，温度可以说是最重要的。推动物种进化的是极端而非平均水平。因此，尽管极端温度事件的频率和强度都在增加，但人们对植物对极端环境的热耐受性的广度知之甚少。这些信息对于了解未来气候条件下的物种分布和生存至关重要。该项目将确定澳大利亚物种在原地和受控环境下生长的温度范围。该项目将有助于为澳大利亚本土植物群落制定有效的保护、恢复和重建计划。
