This readme file contains descriptions of metadata and R code used in the analysis and visualization of the following manuscript: “Symbiotic niche mapping reveals nutrient specialization and functional complementarity among ectomycorrhizal fungi".

Data file = Pinus_Myc_Niche_data.csv

Definitions of column headers:
ID 				Pot identification number in the experiment
REP 				Replicate 1 or 2 depending on which random block treatment (grown on separate shelves in the growth room)
MYC				Original mycorrhizal treatment ID (based on initial control or fungal spore inoculum)
Nitrogen			Application levels of N-containing mineral fertilizer (NH4NO3; mg N kg-1 soil)
Phosphorus			Application levels of P-containing mineral fertilizer (KH2PO4 and K2HPO4; mg P kg-1 soil)
TotalBiomass			Total above- and below ground dried biomass of Pinus muricata seedlings after destructive harvesting
Thelephora_colonization	Colonization of Thelephora mycorrhiza (% root length)
Suillus_colonization		Colonization of Suillus mycorrhiza (% root length)
Total_colonization		Sum total colonization of both Thelephora and Suillus

R markdown file contains all code for analyses and visualization to reproduce results, tables, and figures depicted in the manuscript.
