Temperature Compensation of Energy Metabolism in Tadpoles of the Marsh Frog from Different Populations of the Kamchatka Peninsula (Pelophylax ridibundus Pallas 1771, Anura: Amphibia)

Abstract—The study of the peculiarities of energy metabolism in populations of the marsh frog Pelophylax ridibundus from several reservoirs of the Kamchatka Peninsula with different temperature regimes revealed the temperature compensation of this parameter in tadpoles. The linear dependence of the tadpoles’ metabolic rate on the average annual temperature of habitat was shown. It was found that stable inherited differences in the intensity of tadpoles’ metabolism were formed in 30–20 years from the moment of the first introduction of the species into the reservoirs of Kamchatka. An assumption is made about the limit of adaptive diapason of the species for the development stage 39–40 of tadpoles of the marsh frog.
