Figure 1.

Mean ± standard deviation for three fine root traits along a gradient of soil conditions (NF dataset). Traits are measured on roots <2 mm: specific root length (SRL_c), branching intensity (BI_c) and fine root diameter (D_c). Soil conditions were identified as HO, humid organic; MP, mesic podzol; and XP, xeric podzol. Different letters indicate significant differences between soil conditions; asterisks indicate significant differences between adults (solid line) and juveniles (dashed line) (for P < 0.05).
