The Effect of Temperature on the Oxygen Consumption of Two Species of Fairy Shrimp

Abstract

The oxygen consumption of two. fairy shrimp, Chirocephalopsis bundyi (Forbes) and Eubranchipus vernalis (Verrill), was measured over a range of temperatures (respectively, 5-25 C and 10-20 'C). The metabolic response of both species to a rise in test temperature was similar and dependent on the sex. Thus, while the respiration of both sexes increased over the lower portion of the temperature range, at higher temperatures (i.e., 20 C) male respiration decreased, whereas female respiration was unchanged. Further, over at least part of the temperature range the oxygen consumption of male and Female C. bundyi and female E. vernalis exhibited a respiratory plateau, suggesting the presence of regulation.
