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.

The intrapopulation variability of 20 morphometric characteristics and 26 indices of the body proportions of Karelin’s newt Triturus karelinii (Strauch, 1870) in the Burchu-Gol’ Lake (the Crimea, Chatyrdagh massif, 870 m a. s. l.) was estimated by employing standard statistical methods and discriminant analysis. The studied specimens demonstrated absolute discrimination into two groups, males and females, respectively.
