• preprint DOI: 10.21203/rs.3.rs-1813185/v1

Investigates if published data on plant soil feedbacks can be explained by belowground root strategies

1. SpeciesPSF.R script collects data from publications (using A. Crawford.csv, B. Bennett.csv, C. Petermann.csv)

• |- Prepares species lists for root trait database (sRoot_extraction.RES.PSF.R) see B below

• |- Consistent formating of the plant soil feedback (PSF) variables (Linking PSF.RESpetben.R)

• 1b. sRoot_extraction.RES.PSF.R collects root traits from database (sRoot.trait.Rdata) based on GRoot for species lists (study B and C) from script 1

• |- Collection of root traits for the species lists

• |- Calculation of the root economics spectrum

2. Linking PSF.RESpetben.R
   Combines root traits (output sRoot_extraction.RES.PSF.R) with PSF measures (1.SpeciesPSF.R) and calculates pairwise differences of PSFs in Root Economics Spectrum

3. Tests.Figures.R stats and graphs based on output script 2 (PSF.RES.benpet.Rdata)
