Respiration in Didinium nasutum, an active protozoan predator, was investigated in relation to cell weight at 10, 15, and 20° C by means of cartesian diver microrespirometry. Oxygen uptake increased progressively over the 10-20° C temperature range; a table of Q related to weight is presented. Regression coefficients of log weight versus log oxygen uptake (b) were 0.96 at 10° C, 0.98 at 15° C and 1.00 at 20° C. D. nasutum was shown to expend very much higher levels of respiratory energy than a mainly sedentary carnivorous ciliate of comparable weight.
利用笛卡儿潜水钟微量呼吸测定法，研究了活跃的原生动物捕食者鼻滴虫在10℃、15℃和20℃时的呼吸作用与细胞重量的关系。在10 - 20℃的温度范围内，氧气摄取量逐渐增加；给出了与重量相关的Q值表。在10℃时，对数重量与对数氧气摄取量的回归系数（b）为0.96，15℃时为0.98，20℃时为1.00。结果表明，与体重相当的主要营固着生活的肉食性纤毛虫相比，鼻滴虫消耗的呼吸能量要高得多。
