Respiratory energy losses in the protozoan predator Didinium nasutum Müller (Ciliophora)
journal contribution
posted on 2023-05-16, 20:46 authored by Laybourn-Parry, JRespiration 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 Q10 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. © 1977 Springer-Verlag.
