摘要

The present study investigated thermal effect and acclimation duration on oxygen consumption (R-sp) for Pseudodiaptomus annandalei, a widespread copepod in tropical and subtropical waters. The inflection point of the R:T curve at 32.4 degrees C during the developmental acclimation (DAAC) most probably indicates the upper limit of its thermal optimum for respiration. Interestingly, this upper thermal optimum for DACC closely occurred at the same temperature at which a breakpoint was previously observed during the adult acclimation (AACC). The measurement of Rsp during AACC provides a valuable tool in order to determine the upper thermal optimum for P. annandalei and most probably for many other copepods. The temporal dimension using two acclimation processes emerges as a major factor shaping the relationship between temperature and metabolic rates and would better guide how modelers should consider this essential component in order to improving climate change predictive models.
