Figure 4From: Dissecting the multi-scale spatial relationship of earthworm assemblages with soil environmental variabilityKriged maps of root-related variables (log-transformed values): FiRL (a) and CoRL (c), length of fine and coarse roots, respectively (m sample −1), and FiRW (b) and CoRW (d), weight of fine and coarse roots, respectively (g dry weight sample −1). Darker areas correspond to lower values.Back to article page
