title: [Correlation between the heat resistance of the provisional and definitive muscle tissue during the metamorphosis crisis in frogs].
abstract: Using tadpoles of the lake frog Rana ridibunda Pall. during metamorphosis, a study was made of the heat resistance of the provisional muscle tissue of the tail and of that of two definitive muscles belonging to low-resistant (musculus iliofibularis) and high-resistant (musculus gastrocnemius) groups. It has been shown that during the late metamorphosis a statistically significant direct relation exists between the heat resistance of the provisional muscle tissue of the tail and definitive m. iliofibularis. A comparison with the earlier published data points to a positive correlation between each of these two characteristics and the survival of larvae at high injurious temperature.
