Abstract

SUMMARY: Respiration in well-fed and starved was measured by means of Cartesian diver microrespirometry at 5 °C intervals between 10 °C and 30 °C. At 10C encystment occurred. The optimum temperature for respiration was 25C where a rate of 41·3 × 10 l h per individual was recorded in well-fed animals. Mean cell size also reached a maximum at 25 °C in well-fed individuals. Both respiration rate and mean cell size decreased with starvation, as did the rate of metabolism. A table of daily respiratory energy losses in well-fed and starved Podophrya is presented. The results and their implications are discussed in relation to other protozoa.
