Polymorphism of the Introduced Snail Cepaea nemoralis (Gastropoda, Helicidae) from two Distant Parts of Eastern Europe: Accidental Similarity or Regularity?

The shell coloration of Cepaea nemoralis from Western Ukraine (Ivano-Frankivsk, Lviv, and Ternopil regions) and from the Moscow region of Russia was analyzed, in total, almost 6 thousand specimens from 32 sites. In the samples from the Moscow region, on average, there were half as many yellow shells...
