Summary: We studied the morphophysiological parameters of acid-base balance in sexually mature Pelophylax cf. bedriagae – lake frogs from the Kalinovsky sections forest park and the Beloyarsk reservoir in the vicinity of Yekaterinburg in 2021. It was estimated that in the sampling from the Beloyarsk alkaline reservoir, animals showed a decrease in body weight P (P < 0.05), liver mass (P < 0.03) and fatness (P/L) (P < 0.02) due to man-made pollution in comparison with the sampling from the forest park Kalinovsky sections with slightly acidic pH of the aquatic environment. Lake frogs, which are an invasive species on the eastern slope of the Urals, have characteristic features that distinguish them from higher vertebrates, and are often used as model objects in the study of physiological processes of various organ systems. © Petrozavodsk State University |
