... and separated by periods of apnea lasting on average 47.59min. The bats consumed 0.014 ml O 2 g −1 during ventilation bouts and 0.002 ml g −1 during apnea. The total O 2 uptake was 0.016 ml g −1 for a complete ventilationapnea cycle, giving a Vo2 of 0.020 ml g −1 h −1 1. This value is considerably lower than...
