Thermoregulatory, metabolic and ventilatory parameters measured for the Tasmanian eastern barred bandicoot (Perameles gunnii) in thermoneutrality (ambient temperature = 30 degrees C) were: body temperature 35.1 degrees C, basal metabolic rate 0.55 mL O-2 g(-1) h(-1), wet thermal conductance 2.2 mL O-2 g(-1) h(-1) degrees C-1, dry thermal conductance 1.4 J g(-1) h(-1) degrees C-1, ventilatory frequency 24.8 breaths min(-1), tidal volume 9.9 mL, minute volume of 246 mL min(-1), and oxygen extraction efficiency 22.2%. These physiological characteristics are consistent with a cool/wet distribution, e. g. high basal metabolic rate (3.33 mL O-2 g(-0.75) h(-1)) for thermogenesis, low thermal conductance (0.92 J g(-1) h(-1) degrees C-1 at 10 degrees C) for heat retention and intolerance of high ambient temperatures (= 35 C) with panting, hyperthermia and high total evaporative water loss (16.9 mg H2O g(-1) h(-1)).
