Fig. 6: Effects of plant species richness and the fungicide addition treatment on the relative abundance of fungal functional groups.
From: Soil fungi influence the relationship between plant diversity and ecosystem multifunctionality
The mean (±1 SE) relative abundance of (a) arbuscular mycorrhizal, (b) plant pathogenic and (c) wood saprophytic fungi in communities along a gradient of plant species richness, with and without fungicide addition. Inset text presents estimated effect sizes and statistical significance of the individual and interactive effects of fungicide and plant species richness on the relative abundance of fungal functional groups, based on linear mixed models (n = 190). Orange triangles and blue circles represent control and fungicide addition treatment plant communities, respectively. A series of two-side t-tests with False Discovery Rate correction were used to test whether relative abundance of fungal functional groups differed between fungicide and control treatments at each level of plant species richness (n = 32, 16, 24, 16, and 4 in control plant communities with 1, 2, 4, 6, and 8 species, respectively; and n = 32, 16, 24, 16, and 10 in fungicide addition plant communities with 1, 2, 4, 6, and 8 species, respectively). ***P < 0.001; **0.05 < P < 0.001; *P < 0.05; none P > 0.05. F fungicide treatment; P plant species richness; F × P interactions between fungicide treatment and plant species richness. Source data are provided as a Source Data file.
