description: Additional file 1: Table S1. Mean values ± standard errors and p-values for the soil resistance (SR) response variable and eight explanatory variables that significantly differed (p&lt;0.05) by plant community type. Explanatory variables (n = 252): bulk density (BD), gravimetric water content (GWC), volumetric water content (VWC), total vegetation cover (TVC 1 m2), TVC 700 cm2. Explanatory variables (n = 98): water holding capacity (WHC), nitrogen (N) Data were derived from soils sampled over a three-week period in subalpine meadows (n = 5) at Yosemite National Park, USA. Soils were sampled within two different plot sizes (1 m2 and 700 cm2), in four different plant community types: Calamagrostis breweri (CB), Carex vesicaria (CV), Deschampsia cespitosa (DC), Stipa kingii (SK). Table S2. Mean values, standard errors, and p-values for the soil resistance (SR) response variable and 10 explanatory variables that significantly differed (p&lt;0.05) by meadow gradient class. Explanatory variables (n = 252): gravimetric water content (GWC), volumetric water content (VWC), and coarse fragments (CF). Explnatory variables (n = 98): water holding capacity (WHC), soil organic matter (SOM), nitrogen (N), sand, silt, clay). Data were derived from soils sampled over a three-week period. Soils were sampled in a total of 5 subalpine meadows representing two meadow gradient classes: Low (&lt;2% slope) and Middle (2–4% slope) at Yosemite National Park, USA: Snow Flat (SF) Tuolumne Meadows (TM), Upper Lyell (UL), Emeric Lake (EL), Middle Lyell (ML). Table S3. Emeric Lake meadow gradient, soil texture classification, landscape positions, plant community types, mean values, and standard errors for the soil resistance (SR) response variable and 18 explanatory variables by plant community type. Explanatory variables (n = 252): bulk density (BD), total vegetation cover (TVC), volumetric water content (VWC), gravimetric water content (GWC), coarse fragments (CF), roots, root mass areal density (RMAD), redox depth. Explanatory variables (n = 98): water holding capacity (WHC), soil organic matter (SOM), carbon (C), nitrogen (N), carbon-to-nitrogen ratio (C:N), sand, silt, clay). Data were derived from soils sampled (1 m2 plots) over three-weeks, in two plant community types: Calamagrostis breweri (CB), Stipa kingii (SK). Table S4. Middle Lyell Canyon meadow gradient, soil texture classification, landscape positions, plant community types, mean values, and standard errors for the soil resistance (SR) response variable and 18 explanatory variables by plant community type.
