As Earth’s climate continues to change, the frequency and intensity of warm droughts, extreme precipitation patterns, and heat waves will alter in potentially different ways, ecosystem functioning and productivity with major impacts on carbon and water balance, and food security. The extreme hydro-meteorological conditions that are presently afflicting Australia provide exceptional opportunities to study ecosystem-level functional responses using contemporary, in-situ and satellite observational datasets. This project aims to analyse cross-biome and site-level functional responses across contrasting hydroclimatic periods to better understand climate change impacts on ecosystem productivity, resilience, and potential collapse.

随着地球气候的持续变化，暖干旱、极端降水模式和热浪的频率和强度将以潜在的不同方式改变生态系统功能和生产力，对碳和水平衡以及粮食安全产生重大影响。目前正在影响澳大利亚的极端水文气象条件为利用当代、现场和卫星观测数据集研究生态系统一级的功能反应提供了难得的机会。该项目旨在分析不同水文气候时期的跨生物群系和站点级功能响应，以更好地了解气候变化对生态系统生产力，恢复力和潜在崩溃的影响。
