  • Rock crevices (T IN +9C to +33C) were warmer and thermally more stable than tree hollows (T IN ?4.0C to +37C)Torpor, often expressed by a reduction of T skin/ Tb by >10C for 34h at dawn,was influenced by roost selection; torpor use in tree hollows was almost twice that in rock crevices (ref: DoucBrig2011)
