Thermoregulation, gas exchange, and ventilation in Adelie penguins (Pygoscelis adeliae)

Adelie penguins (Pygoscelis adeliae) experience a wide range of ambient temperatures (Ta) in their natural habitat. We examined body temperature (Tb), oxygen consumption (VO2), carbon dioxide production (VCO2), evaporative water loss (mH2O), and ventilation at Ta from -20 to 30 degrees C. Body temperature did not change significantly between -20 and 20 degrees C (mean […]
