Intraspecific differentiation in the root system of Potentilla matsumurae along a snow accumulation gradient in mid-altitude alpine environment

Figures & data

Figure 1. The dynamics of soil temperatures in 2016. Thin black line shows the soil temperature at 10-cm depth in the fellfield, thick black line shows surface temperature in the shallow snowbed, and thin gray line shows surface temperature in the deep snowbed, respectively

Figure 2. (A) Gravimetric soil moisture, (B) soil ammonium availability, and (C) soil nitrate availability in surface soil. Inorganic nitrogen availability was determined with the resin bag method (Binkley and Matson 1983). FF = fellfield, SS = shallow snowbed, DS = deep snowbed. Different letters shown under the habitat name indicate statistical difference by Tukey’s HSD multiple comparison test (p < .05). n.s. means not significant

Figure 3. Differentiation of functional traits among fellfield (FF), shallow snowbed (SS), and deep snowbed (DS): (A) aboveground biomass, (B) belowground biomass, (C) aboveground:belowground (S:R) ratio, (D) coarse root biomass, (E) fine root biomass, (F) coarse root:fine root (C:F) ratio, (G) SRL, and (H) root tip density. Different letters shown under the habitat name indicate statistical difference by Tukey’s HSD multiple comparison test (p < .05). n.s. means not significant
