Extended Data Fig. 8: Comparisons of plant and microbial community evenness between non-degraded (ND) and degraded grasslands (DG).
From: Grassland degradation alters plant and soil biodiversity–multifunctionality relationships
a, Plant evenness; b, bacteria evenness; c, fungi evenness; d, protist evenness. The ends of a box denote the 25th and 75th quartiles, and whiskers extend to 1.5 times the standard deviation (n = 44 independent sites). The horizontal line within each box represents the median value. The open circles represent the values for each site. Linear mixed models with a correction for environmental covariates were employed to conduct statistical comparisons between non-degraded and degraded grasslands across the 44 sites (plant: F1,48.52 = 143.60, P = 4.15 × 10−16; bacteria: F1, 42.24 = 11.05, P = 0.0018; fungi: F1, 48.86 = 4.45, P = 0.0400; protist: F1, 50.95 = 0.25, P = 0.6211; the two-sided P values were not corrected for multiple comparisons). Climate and soil factors were treated as covariates, site and grassland type (alpine steppe, alpine meadow or swamp meadow) were treated as random factors.
