About the research project
Highland grasslands are a dominant and crucially important component of Australia’s alpine and sub-alpine ecosystems. These communities support unique biodiversity and have enormous aesthetic and emotional appeal. What is perhaps less obvious, however, is that these communities also support soils that are extremely dense stores of carbon, due to their peaty nature caused by the accumulation of undecomposed plant material. These peaty soils are crucial to Australia’s prosperity - capturing, storing, filtering and releasing water worth $A10 billion p.a. to the Australian economy. By absorbing and then later releasing vast amounts of water, these soils help prevent floods during wet periods and keep rivers flowing during drought and their ability to do so is entirely dependent upon their peaty nature. However, highland peatlands are potentially threatened by climate change, most importantly by global warming, which could lead to increased loss of soil carbon through higher rates of decomposition and reduced carbon inputs.
This project will make use of state of the art experiments that artificially warm grassland plots in highland areas in Tasmania and on the Australian mainland to predict how grassland soil carbon stocks and fluxes will respond to future climates. The project will combine measurement of carbon pools and fluxes in several highland sites with modern process-based modelling to determine the level of threat future climates pose to this crucial aspect of a largely-overlooked ecosystem.
The successful candidate will work in the Australian Mountain Research Facility and will be jointly based in the University of Tasmania in Hobart and the Australian National University in Canberra, supervised by Prof. Mark Hovenden (UTas) and Prof. Adrienne Nicotra (ANU), both of whom lead dynamic research groups investigating the impacts of the changing climate on Australia’ high altitude areas and ways that adaptive management can ensure long term sustainability of these ecosystems.
