Influence of temperature acclimation on respiration-temperature relationship in Tetrodontophora bielanensis (Collembola: Onychiuridae)
- N/A
CO2 output in Tetrodontophora bielanensis was measured in the temperature range 0 to 20°C using gas chromatography after acclimation to 5, 13 and 19°C in the laboratory. The effect of acclimation temperature on mean CO2 output was not significant. The relationship between respiration and experimental temperature was found to vary depending on the acclimation temperature. It was not possible to obtain a significant mathematical description of the relationship after acclimation to 5°C. The relationship was exponential at acclimation temperature 13°C and linear after acclimation to 19°C. The importance of acclimation to temperature and metabolic cold adaptation in different populations is discussed.
