Features of some population characteristics of the marsh frog (Pelophylax ridibundus) (Ranidae, Amphibia) on the Right Bank of the Volga river in the Nizhni Novgorod region

In 2022 and 2023, some population characteristics of the marsh frog (Pelophylax ridibundus) were studied on the right bank of the Volga River, near the village of Somovka, Vorotynsk district, Nizhny Novgorod region. When comparing data for two different years, differences in the distribution of color phene frequencies were found, and in some cases they reached the interpopulation level.

Modelling the range dynamics of the marsh frog (Pelophylax ridibundus) (Ranidae, Amphibia) in Russia under alternative scenarios of global climate change

Predictive maps of the distribution of the marsh frog (Pelophylax ridibundus) in Russia under the conditions of global climate change up to 2100 are presented. It is shown that under the influence of global climate change, the range will expand and the centroid will shift to the north-east.

Influence of the geochemical background of the Western Caspian region of Azerbaijan on acid-base balance regulation of Pelophylax ridibundus (Pallas, 1771) (Amphibia, Ranidae) blood

This research paper examines the influence geochemical specifics of habitats on acid base balance of marsh frog blood. An aquatic species, P. ridibundus, is surrounded throughout its entire life cycle by an aquatic environment, which ensures the free exchange of gases and ions across the entire surface of the body, thanks mainly to passive and active transport, which is easily realized in a significant volume.
