Figure 1. High and low aridity sampling sites, andT. triandra plant trait responses to treatment effects. (a) High and low aridity sampling sites for the collection of soil microbiota for experimental manipulation (yellow points). Mean annual aridity index data layer (ADM) is sourced from the Soil and Landscape Grid of Australia (Searle et al. 2022), where aridity index is calculated via annual precipitation/annual potential evaporation. T. triandra plant growth responses to soil aridity, sterilisation treatments, and water stress, showing: T. triandra (b) total biomass, (c) aboveground biomass, (d) belowground biomass, and (e) root-mass fraction differences.
