Fig. 3. Angular deviation of movement direction. Frogs tend to deviate from movement directly toward the road within 3.3 m of the road surface. Movement bands 1, 2, and 3 at low- and high-traffic sites correspond to 10.0–6.7 m, 6.6–3.4 m, and 3.3–0.0 m from the road surface, respectively. At control sites, movement bands 1, 2, and 3 correspond to 10.0–6.7 m, 6.6–3.4 m, and 3.3–0.0 m from the end of the 10-m monitoring area (see Fig. 1).
