title: Temperature and immobility reaction in Rana temporaria.
abstract: Experiments were conducted on two groups of Rana temporaria acclimatized to 7°C and to 14°C. Two hours prior to the experiments the animals were divided into six groups of 40 subjects each and placed in containers at temperatures of 5°, 10°, 15°, 20°, 25° and 30°C. Frogs remained immobile for a shorter time in temperatures which differed little from those of acclimatization. It was concluded that the body temperature interferes with the duration of the immobility reaction.
