Angle of den entrance
Based on our on-site measurements, we found that the angle of the den
entrance on shady slopes was 32.87
± 3.98°, which was significantly lower than that on sunny slopes (38.67
± 4.23°) and in flat areas (38.13 ±
3.92°)
(F2, 128 = 1.39, P < 0.05). However,
the angle of the den entrance was not significantly different between
those on sunny slopes and in flat areas (F1, 129 = 2.37,P = 0.083) (Fig. 7).
