Abstract

Demographic characteristics of marsh frog (Rana ridibunda Pall.) populations have been studied in cooling reservoirs of Middle Ural thermal power plants, where this species was introduced accidentally. The reservoirs are similar in hydrochemical characteristics but differ in the thermal regime. The populations studied have been found to differ from the reference (natural) populations and from each other in a number of parameters, including the size and age composition of spawners, the type of spawning, and fecundity. Analysis of the results indicates that the observed differences have adaptive significance.
