Abstract
Thermal acclimation in the free‐living soil nematode, Caenorhabditis elegans was studied by determining effects of both growth and test temperatures on oxygen consumption and behavior. Growth temperature (15, 20, or 25°C) had no significant influence on oxygen consumption in the range 10–30°C, although cold‐grown worms had higher consumption at 5°C. In contrast, measurements of the fraction of worms moving at any instant and of chemotaxic ability both showed nearly complete thermal acclimation (in the sense that activity‐temperature relationships were shifted nearly as much as the differences in growth temperature). Measurements of the rates of acclimation using the behavioral assays indicated acclimation is half complete in about two hours.
