FIGURE 3. Quantitative burrow properties. A) Measurements were taken for number of surface openings (SO), burrow slope (S), maximum depth (D), total length (L), tunnel, shaft, and chamber width (w), height (h), and circumference (c), and branching angles (BA). B) Complexity includes the number of segments (s), chambers (h), and surface openings (e) within a single burrow system. C) Tortuosity of a single burrow segment is found by dividing the total length (u) by the straight-line distance (v) from end to end. Modified from Hembree (2019).
