Do hotter and drier regions harbour adaptive variation for climate change?

这个项目旨在提高我们对树木应对气候变化能力的认识。这对维持生物多样性、森林健康和生产力至关重要。在澳大利亚西南部，气候变化增加了干旱的频率和强度，导致树木死亡，并对基本生态系统服务产生负面影响。在快速变化的气候下，迫切需要适应性土地管理来减轻大规模干旱死亡的风险。本项目旨在通过对遗传适应和生理耐受性的详细了解，为在西南森林采用辅助基因迁移提供科学依据，以提高在未来更热更干燥气候下的抗旱能力。

This project aims to improve our understanding of the capacity of trees to respond to climate change. This is essential for the maintenance of biodiversity, forest health and productivity. In south-west Australia, climate variation has increased the frequency and intensity of droughts, which has resulted in tree death and negatively affected essential ecosystem services. Adaptive land management is urgently needed to mitigate the risk of large-scale drought mortality in a rapidly changing climate. This project seeks to deliver a scientific basis for the adoption of assisted gene migration in south-west forests, through a detailed understanding of genetic adaptation and physiological tolerance, to improve drought-resilience under future hotter and drier climates.
