Příjem potravy a metabolická aktivita .i.Galumna elimata./i. (C.L. Koch, 1841) (Acari: Oribatida) při různých teplotách
Šustr, Vladimír ; Hubert, J. ; Pekár, S.
The ability of the physiological compensation of respiration rate and feeding activity for temperature was tested in oribatid mite .i.Galumna elimata./i. to evaluate significance of the increase of amylolytic activity in the whole body homogenates of mite exposed to cold acclimation. Mites were reared on green bark algae (.i.Protococcus viridis./i.) at different constant temperatures (5-30°C) for 21 days. The temperature relationships of respiration rate, presence of animals on food and defecation were compared before acclimation (quick response to temperature change) and after acclimation to constant temperature (effects of adaptation). The relationship of oxygen consumption on temperature was similar in control and acclimated mites. Presence of animals on food increased exponentially with temperature before acclimation. It was higher at 15°C after acclimation at constant temperature.
