Project Description

The current rate of species extinctions is so extensive that it has been described as the 'sixth mass extinction'. In Australian ecosystems, extinctions and declines of mammals have been dramatic, with formerly abundant species now 'ecologically extinct', i.e., too rare to continue to play important ecological roles. The loss of entire functional guilds may have cascading effects on biodiversity and ecosystem function. I use a multi-scalar experimental approach to investigate the broader impacts of mammal declines on Australian ecosystems, accounting for interactions with climate. The outcomes will include new insights into the pre-European state of Australian ecosystems and more realistic targets for ecosystem restoration.
