- Аннотация: Our study provided the first data about age structure and growth of the marsh frog, Pelophylax ridibundus, from the different habitats of invasive part of this species range in Kamchatka.The minimal and maximal ages in males were 1 and 7 years, respectively, with mean age of 2.97 years. The majority of males were 2 or 3 years old. The age in females ranged from 1 to 6 years with mean value of 2.82 years. The majority of females were 2-3 years old also. Due to relatively long activity season, marsh frog males can reach maturation after first wintering, and females – after 1st or 2nd wintering.
