title: Chromosomes of Pelophylax ridibundus Pallas, 1771 in different population systems of southern Ukraine
abstract: Abstract This paper provides the comparative morphological analysis of P. ridibundus chromosomes in different population systems of southern Ukraine. A certain variability and heteromorphism of individual homologs and of whole chromosome pairs was established. The chromosomes of P. ridibundus in populations consisting of a single species (Crimea, Zalisne, Arabat Spit) are relatively stable in quantitative and qualitative terms. Karyotypes are more variable in the lower reaches of the Dnipro Rive
