Table 1. Parameter estimates of common brushtail possum (T. vulpecula) traits used to model the physiological costs of inhabiting nest boxes painted different colors during summer and winter.

Parameter	Value	Reference
Body size (kg)	2.2	Clinchy et al. [60]
Core temperature (°C)	36.2	Dawson and Hulbert [58]
Basal metabolic rate (W)	4.2	Predicted using allometric equation from Dawson and Hulbert [58]
Fur conductivity (W/m°C)	0.04	Default mammal value, see Porter and Kearney [59]
Fur depth (mm)	18.81–22.98	Weighted average of dorsal and ventral fur depth measurements from T. vulpecula museum specimens based on modelled posture (n = 21)
Posture (ratio length:width)	1.1–4.0	Minimum estimated for a possum curled in a ball and maximum calculated based on measured surface areas of museum specimens
