Morphological and genetic differentiation among three populations of the marsh frog, Rana ridibunda , from northern Greece was examined using selected morphometric characters and electrophoresis of polymorphic enzymes. Two discordant differentiation patterns emerged; while the Mahalanobis distances between the populations (range 0.6948* to 1.8824***) based on three morphometric discriminators were significantly correlated to altitudinal difference, the genetic differentiation in eight enzyme loci (0.011 ≤Nei's unbiased D≤0.096; 0.110≤ Rogers' modified distance ≤ 0.286; G ST =17.4%) appeared random and grouped the populations differently. The overall pattern is interpreted as a response to different selection regimes in the morphometric phenotype (including presence of a syntopic congener), absent in the allozymes.
