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. Q values of 1.15-2.24 were found for four of the species between 8.5-15° C, while in S. teres a Q of 12.98 occurred between these temperatures. Between 15-20° C T. pyriformis and P. aurelia had Q 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.
利用笛卡儿潜水钟微量呼吸测定法，在8.5℃、15℃和20℃下研究了五种纤毛原生动物（梨形四膜虫、小口钟虫、双小核草履虫、长柱旋口虫以及亮大草履虫）的呼吸能量损失。在8.5 - 15℃之间，发现其中四个物种的Q值在1.15 - 2.24之间，而在长柱旋口虫中，这两个温度之间的Q值为12.98。在15 - 20℃之间，梨形四膜虫和双小核草履虫的Q值分别为3.73和1.56。在每个温度下得出了耗氧量与干重的线性双对数回归方程，得到的回归系数（b）分别为0.2723（8.5℃）、0.4364（15℃）和0.4171（20℃）。结合先前关于纤毛原生动物能量学的研究对结果进行了解释和讨论。
