My PhD (2000-2004) with Professor Steve Tyerman, Dr Peter Anderson and Dr Molly Whalen from Flinders University, measured salt and drought tolerance ecophysiology of a natural hybrid of Eucalyptus largiflorens, called Green box. This tree survives the harsh conditions on the Chowilla floodplain of the River Murray. The aim was to select trees for revegetation by screening seedlings with traits and AFLP DNA markers. Traits were leaf carbon and nitrogen and the abundance of their natural isotopes (13C and 15N), and specific leaf area. Rates of photosynthesis, transpiration and stomatal conductance were also monitored for calculation of water use efficiency and occurrences of non-stomatal conductance indicative of plants ability to cope with water/salt stress. My Postdoctoral research (2005-2007) at Bangor University in Wales with Prof Davey Jones, Prof Gareth Edwards-Jones and Dr Paul Hill, formed carbon budgets for vegetable production in the UK, Spain and Uganda. Components were soil respiration, plant biomass and soil organic matter and soil parameters for the DNDC (denitrification and decomposition) model.

I am interested in carbon and water ecosystem balance. I am working with Professor Wayne Meyer (University of Adelaide) and Dr Peter Cale (Australian Landscape Trust) on the Calperum flux tower, Calperum Station near the Chowilla floodplain and Renmark, South Australia. The tower records data to our website : http://www.landscapescience.org/ At the website, click on the data tab to see updates every 6 hours.

We are one of the Australian Government's TERN SuperSite and Ecosystem Processes OzFlux towers. Our data contributes to Global datasets of Fluxnet (Calperum, Site ID: AU-Cpr) and NASA's Ecostress mission.
