Soil phosphorus drives subcontinental patterns of carbon-isotope discrimination across Australia

This data repository contains datasets and analysis code for the paper published in New Phytologist entitled \"Soil phosphorus drives subcontinental patterns of carbon-isotope discrimination across Australia\". In the article, we analysed stable carbon isotope data for previously published transects, alongside new measurements from a transect in northeastern Queensland, to explore potential drivers of regional-scale sensitivity of carbon isotope discrimination to mean annual precipitation. Based on our analyses, we concluded that higher stomatal conductance in phosphorus-poor regions of Australia appeared to moderate the otherwise well-known decrease in carbon isotope discrimination with decreasing precipitation. We suggested that high transpiration rates in these regions help to facilitate phosphorus foraging in phosphorus-impoverished, ancient soils.
