Present distribution of the common frog, Rana temporaria and the moor frog, R. arvalis (Amphibia, Anura) in the “old” Moscow

The common frog (Rana temporaria) and the moor frog (R. arvalis) lived in all green areas of Moscow until the end of the 20th century. The reduction in the area of woody vegetation, the destruction of breeding sites and introduction of the invasive fish Perccottus glenii contributed to the extinction of these amphibians in most of the city. The paper provides information on the distribution of brown frogs in Moscow based on the results of monitoring in 2020. R.

On the Distribution of the European Common Spadefoot, Pelobates fuscus (Pelobatidae, Amphibia) in Moscow

The European common spadefoot, Pelobates fuscus, has not been observed in Moscow since the end of the 20th century. The species is listed in the Red Data Book of Moscow (2017) as endangered or completely extinct. The paper presents new findings of P. fuscus on the territory of the city, namely, in the “Moskvoretskiy” Natural-Historical Park and the “Kosinskiy” Natural-Historical Park in August 2020.

Comparative Characteristics of Morphometric and Reproductive Parameters of the Common Brown Frog, Rana temporaria (Amphipia, Ranidae) from the Populations of Old and New Moscow

The paper discusses the results of our study of the variability of some morphometric and reproductive characteristics in the common brown frog, Rana temporaria, from two populations of the Moscow city. The first population exists in isolation in the Timiryazev Forest Park, for a long time surrounded by districts with multi-storey buildings. The second population is located on the territory with mainly rural buildings (the settlement Kokoshkino), recently annexed to Moscow. The size and reproductive parameters in frogs from these two localities were compared.


During the field season of 2014, research was conducted on 5 areas planned for organizing protected areas in Kazan City. The examined areas were found to be important for preserving the diversity of amphibians and reptiles in the city. Of major concern is preservation of the northern crested newt (Triturus cristatus Laurenti, 1768) and the common toad (Bufo bufo, Linnaeus, 1758) in those territories, the species listed in The Red Data Book of the Republic of Tatarstan.
