Abstract
Respiratory energy losses in five species of ciliated protozoa, Tetrahymena pyriformis Ehrenberg, Vorticella microstoma Ehrenberg, Paramecium aurelia Ehrenberg, Spirostomum teres Claparède and Lachmann and Frontonia leucas Ehrenberg, were investigated at 8.5° C, 15° C and 20° C using Cartesian diver microrespirometry. Q10 values of 1.15-2.24 were found for four of the species between 8.5-15° C, while in S. teres a Q10 of 12.98 occurred between these temperatures. Between 15-20° C T. pyriformis and P. aurelia had Q10 values of 3.73 and 1.56, respectively. Linear double log regressions of oxygen consumption vs. dry weight were derived at each temperature and regression coefficients (b) of 0.2723 (8.5° C), 0.4364 (15° C) and 0.4171 (20° C) were obtained. The results are explained and discussed in relation to previous work on the energetics of ciliated protozoa. © 1976 Springer-Verlag.
