Figure 2. Duration of torpor bouts (log₁₀) as a function of the minimum Ta of each torpor bout.

All torpor bouts recorded are represented by the open circles and dashed line (log₁₀ TBD = 2.1–0.09[T_a °C]; R² = 0.2, P<0.001, F_1,209 = 55.0). The two longest bouts recorded for each individual are represented by the closed circles and solid line (log₁₀ TBD = 2.7 - 0.1[T_a °C]; R² = 0.8, P<0.001, F_1,25 = 73.3).
