Data from: 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.
