Temperature dependence and ontogenetic changes of metabolic rate of an endemic earthworm Dendrobaena mrazeki

Popis výsledku v původním jazyce

Ontogenetic changes and temperature dependency of respiration rate were studied in Dendrobaena mrazeki, an earthworm species inhabiting relatively warm and dry habitats in Central Europe. D. mrazeki showed respiration rate lower than in other earthworm species, <70 ?l O2 g-1 h-1, within the temperature range of 5-35°C. The difference of respiration rate between juveniles and adults was insignificant at 20°C. The response of oxygen consumption to sudden temperature changes was compared with the temperature dependence of respiratory activity in animals pre-acclimated to temperature of measurement. No significant impact of acclimation on the temperature response of oxygen consumption was found. The body mass-adjusted respiration rate increased slowly withincreasing temperature from 5 to 25°C (Q10 from 1.2 to 1.7) independently on acclimation history of earthworms.
