Analyses accounting for Fungal abundance and diversity at 8 months
Mass loss . PIA directly increased mass loss, but the effect was much weaker than interaction term and hence not interpretable, and there was a negative interaction between PIA and Fungal diversity on mass loss (Supplementary Table S3).
Carbon loss . PIA tended to directly increase C loss, and there was a negative interaction between PIB and Fungal diversity on C loss (Supplementary Table S3).
Nitrogen loss . PIA directly decreased N loss, and there was a tendency of a positive interaction between PIA and Fungal diversity on N loss (Supplementary Table S3).
