In the Rana temporaria population introduced into the south of Kamchatka, high variation in the rate of larval growth and development was revealed, due to differences between spawning pools, some of which being fed by thermal groundwater. As a consequence, the variability in the timing of metamorphosis was also high and comparable to that detected in populations of the native part of the range with a longer period of activity. In the tadpoles of R.

The results of our first short-term study of a unique Rana temporaria population in May, 2015, are reported. This population was formed in the southern Kamchatka as a result of releasing 150 immature frogs in the spring of 2005. The numbers of breeding females was 2,648 in 2015. The activity season duration at the release locality (4 months) is 2 months shorter than that at the original locality of the translocated frogs in Moscow district.
