Cascading effects of Australia's ecological extinctions on biodiversity and ecosystem function. 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”, meaning they are too rare to continue to play important ecological roles. The loss of entire functional guilds may have cascading effects on biodive ....Cascading effects of Australia's ecological extinctions on biodiversity and ecosystem function. 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”, meaning they are too rare to continue to play important ecological roles. The loss of entire functional guilds may have cascading effects on biodiversity and ecosystem function. This project uses 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.Read moreRead less
Testing the importance of large-scale climate factors to plant community assembly following land-use change. This project will examine the native plant species and functional diversity of Australia's rain forest communities to create a predictive framework of how plant communities recover following deforestation. Such a framework is key to focusing conservation efforts in degraded and multi-use landscapes.
A general theory for ecological trait-strategy dimensions. This project aims to bridge the gap in understanding of ecological strategies between plant and animal ecology, globally, using ants. It will test how environmental change influences the success of species, based on ecological strategies, and the consequences for ecosystem function. This project is expected to make a significant contribution to generality and prediction in ecology. Expected outcomes of this project include theory deve ....A general theory for ecological trait-strategy dimensions. This project aims to bridge the gap in understanding of ecological strategies between plant and animal ecology, globally, using ants. It will test how environmental change influences the success of species, based on ecological strategies, and the consequences for ecosystem function. This project is expected to make a significant contribution to generality and prediction in ecology. Expected outcomes of this project include theory development and application and enhanced global networks of trait researchers. Intended benefits include improved ecological theory, an enhanced capacity to predict how global change will affect organisms and increased understanding of the cascading effects of changes for ecosystem function.Read moreRead less
