Shchukinsky Peninsula as a New Habitat of the Grass-snake Natrix natrix (Linnaeus, 1758) (Colubridae, Reptilia) in Moscow

Authors: Kuzikov I. V.

The paper provides new information about the Moscow findings of the grass snake Natrix natrix, listed in the Red Data book of this city. Regular meetings of common grass snakes on the territory of the Shchukinsky Peninsula for a significant period, starting from 2012, indicate its relatively stable, but low population abundance.

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

Authors: Stepankova I. V., Afrin K. A., Ivolga R. A., Kidov A. A.

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.
