Next-generation vegetation model based on functional traits. Global vegetation models try to answer big questions, such as the effects of climate change and carbon dioxide (CO2) on ecosystems and vice versa. But as present models are outdated and give inconsistent results, the project is planning a new, more robust model that will fully exploit recent advances in plant functional ecology and earth system science.
Integrating biomechanics and ecology: moving from an individual- to population-level understanding of the effects of environmental change. Coral reefs, a key Australian resource, face an uncertain future due to environmental change. Up to now, environmental change research has focused on the individual level, severely limiting our predictive capacity. This project will develop a novel 'first principle' approach to solve this shortcoming and make population-level predictions possible.
Drought effects on soil carbon and nitrogen cycling mediated by rhizosphere processes. There is much uncertainty about how drought caused by global warming will affect agricultural sustainability in Australia. This project will provide new knowledge about plant-soil interactions affecting carbon and nutrient cycling and will make predictions about long-term soil carbon storage and agricultural productivity in response to drought.
Examining the vulnerability of ocean carbon biogeochemistry in a high CO2 world. Rising CO2 levels in the atmosphere from human activity is changing the biogeochemistry of the ocean, with large potential consequences on future atmospheric CO2. This work will explore these changes and will result in a more complete understanding of how the ocean will either accelerate or delay the increase in atmospheric CO2.
