摘要

A comparative analysis of fecundity in the Moscow population of Rana temporaria L. and Rana arvalis Nilss. was performed. The highest fecundity was detected in the city population. The average egg diameter is smaller and a relative amount of yolk is higher in the clutches of the city frogs. No correlation between the female fecundity and egg diameter was found. The results obtained allow one to suppose that the evolutionary changes in the reproductive strategy is an adaptation of the brown frog to anthropogenic pressure of the city.
