The influence of malnutrition on the postprandial metabolic rate and respiratory quotient [PDF]

British Journal of Nutrition, 1972
1. Pre- and post-prandial metabolic rates were measured in twelve malnourished Jamaican infants.2. On admission to hospital, minimal increase in postprandial metabolic rate were found, whereas during the recovery phase when growth was rapid, inreases in postprandial metabolic rate of up to 38% occurred.3.

AN APPARATUS FOR THE STUDY OF RESPIRATORY QUOTIENT AND BASAL METABOLISM OF MICE [PDF]

Journal of Experimental Medicine, 1930
A simple apparatus has been developed for the study of the respiratory quotient and basal metabolism of mice. Data are given which indicate that the values for the respiratory quotient obtained are accurate to within 0.02. The apparatus is especially designed for rapid, routine manipulation.

Evolutionary temperature compensation of carbon fixation in marine phytoplankton [PDF]

, 2020
The efficiency of carbon sequestration by the biological pump could decline in the coming decades because respiration tends to increase more with temperature than photosynthesis.

Tree stratum alteration decreases C use efficiency and the stability of litter decomposition in a sacred fir (Abies religiosa) forest

Botan‪ical Sciences, 2022
Background: There is limited information to predict the direction in which canopy modification affects the microbial carbon use efficiency (CUE) and, consequently, the magnitude and stability of litter decomposition in monodominant sacred fir (Abies ...
