DATASET: Fire shapes fungal guild diversity and composition through direct and indirect pathways

Fungi_guild_fire code.R file provides code used in the analyses in this study. Supporting Data document includes: Table S1: Number of years-since-fire and number of times burnt for each site Table S2: Hypotheses and rationale for paths used in SEM only including the fungal variable: total richness, NH3, nitrate, TOC, total organic carbon Table S3: Hypotheses and rational for paths used in SEM including fungal guild groups: ectomycorrhizas, saprotrophs, and pathogens. NH3: nitrate, TOC: total organic carbon Table S4: Goodness of fit of time-since-fire, successional stages, fire frequency, and fire frequency classes on fungi and trophic guild composition based on the envfit function using NMDS plots Table S5: Indicator species analysis showing associations of fungal species with post-fire successional stages and fire frequency classes. Indicator value (Ind Val): strength of association to group, p-value: significance (p ≤ 0.05 deemed significant), recently burnt: 0 – 2.5 years post-fire, mid-succession: 2.5 – 8.5 years post-fire, late-succession: 8.5 – 33.5 years post-fire, long unburnt: 33.5 + years post-fire, low fire frequency: burnt ≤ 2 times over 29-year period, high fire frequency: burnt 3 – 5 times over 29-year period. Species only shown if indicator value ≥ 0.25, significant, and if unique to one group. ASVs bolded if they show a preference for both a post-fire successional stage and a fire frequency class Table S6: Data used in the structural equation model.
