OXYGEN CONSUMPTION IN <i>DIAPTOMUS</i>

Abstract

The oxygen consumption of fed and unfed Diaptomus siciloides, D. oregonensis, D. leptopus, and D. clavipes was measured at five different temperatures using a micro‐Winkler technique. Regression relationships between log oxygen uptake and each of the following independent variables, temperature, log length, and log weight, as well as the combinations of temperature and length and of temperature and weight, were examined for the four species mentioned and Diaptomus arcticus and Mixodiaptomus laciniatus. The simple regression of log oxygen consumption on log dry weight at the five temperatures and the multiple regression of log oxygen consumption on temperature and log dry weight gave close approximations to the experimental means.
