Oxygen consumption of brown noddy (Anous stolidus) embryos in a quasiequilibrium state at lowered ambient temperatures.
1. The oxygen consumption (MO2) of the semi-precocial Brown Noddy embryos at different stages of development was measured at 36 degrees C and again after 5-hr exposure to lowered ambient temperatures (30 and 32 degrees C). 2. The MO2 measured in a quasiequilibrium state was equal to the value predicted by a temperature coefficient of 2. 3. In contrast to precocial chickens, the semi-precocial Noddy had no apparent metabolic response to cooling before hatching.
