It would be dangerous to incubate (keep and grow) cultures at temperatures close to body temperature (37Â°C) because doing so might allow the growth of pathogens harmful to health. So the maximum temperature used in school and college labs is 25Â°C.
We cultured experimental populations of the ciliate Paramecium caudatum in two constant temperature environments (23 Â°C and 35 Â°C) and in 4 temporally variable temperature environments, with random daily fluctuations between 23 Â°C and 35 Â°C.e compare the adaptation of populations of the ciliate Paramecium caudatum exposed to constant (23 Â°C or 35 Â°C) and temporally variable temperature environments (random daily fluctuations between 23 Â°C or 35 Â°C).
