Sensitivity_analysis.R - code to create Supplementary Figures & Tables from the manuscript. This is only the extended sensitivity analysis of each parameter. In some sections, the competition models are re-written so as to allow a parameter to vary from the default value without changing the model used for the rest of the analysis.

NPP_models_wCO2.R - competition model code with variable carbon dioxide concentration input. Otherwise, identical to NPP_models.R. These models are used in Main_figures.R and Supplementary_figures.R

Compile_parameters.R - Contains data informed parameters for the competition model. The products of this script should be saved in one RData file for use in Main_figures.R, Supplementary figures.R, and Sensitivity_analysis.R

TRY_analysis_1.R & TRY_analysis_2.R - processing script for all traits downloaded from the TRY plant trait database. Some traits included in this script were excluded from the final analysis due to there being too few liana species or because the definition of the trait was called into question. The data are not available, but the analysis can be repeated by following the steps outlined in Supplementary Methods: TRY analysis. All data were read in as txt files with the original name assigned from the TRY database. Species-averaged trait values and corresponding growth forms were compiled in the file output_9oct.csv (TRY_analysis_1.R) and filtered_TRY_analysis_16-03-21.csv (TRY_analysis_2.R)
