Periodicities and transient shifts in anuran (Xenopus laevis, Rana clamitans) oxygen consumption revealed with flow-through respirometry.

1. A custom-designed, computer-controlled, flow-through respirometry system was used to monitor oxygen consumption in aquatic anurans: Xenopus laevis metamorphs and larval Rana clamitans. 2. There was no evidence that animals were stressed in the flow-through respirometer; oxygen consumption rates in static vs open mode fell within the same range and animals were quiescent in the chambers. 3. Diurnal periodicity was pronounced in X. laevis: both mean rates and variability of oxygen consumption were higher during scotophase, although individual differences in the timing of peaks were pronounced. 4. A transient peak in metabolism following introduction of ethanol, with subsequent recovery, was monitored for X. laevis.
