Rana arvalis

On findings of colour anomalies in the moor frog Rana arvalis Nilsson, 1842 (Ranidae, Amphibia) in the Moscow region

Authors: Katz A. V.

Information on two findings of colour anomalies in the moor frog, Rana arvalis, in the Moscow region is prerented. In one case, the colour anomaly in a frog found in Shchelkovo District was probably the result of a decrease in the number of iridophores. This anomaly corresponds to none of the colour morph of R. arvalis described previously. The second finding was made in Volokolamsk District, and the colour anomaly was expressed in a strongly pronounced spotted pattern, which is unusual for this species.

Amphibians of the Orenburg State Nature Reserve (Russia)

Authors: Gorelov R. A., Bakiev A. G.

Literary information about the batrachofauna of the Orenburg nature reserve is incomplete and contradictory. Data on the specific composition and abundance of amphibians in the Orenburg Nature State Reserve at its five cluster territories by the results of our 2015–2020 inventory are presented. The previously published materials about amphibians on the cluster territories “Talovskaya Steppe”, “Burtinskaya Steppe” and “Aytuarskaya Steppe” have been supplemented.
