Figure 1

Heart rate as a function of ambient temperature (Ta) for Nyctophilus gouldi and Syconycteris australis. Basal HR (filled circles) was recorded in the thermoneutral zone (TNZ; 29.5–34 °C). Below the TNZ, resting HR (triangles) increased linearly for both species; (A) HR (bpm) = 682.57 -14.03 (Ta), (B) HR (bpm) = 582.32 -7.34 (Ta). Bats entered torpor (filled squares) when exposed to Ta below 25 °C (Ng) and 20 °C (Sa).
