Researching Malformations in Frogs of the Pelophylax esculentus Complex (Amphibia: Anura) in the Natural Populations of the Trakhtemyriv Peninsula (Ukraine)

Abstract

As a result of research held during student practicals between 2012 and 2016 and a study of the population of the Pelophylax esculentuscomplex, we have found up to 13.3% of samples from the species Pelophylax ridibundus have abnormalities. Moreover, 6 different variants of limb malformations have been found: phocomelia, rotation, ectrodactyly, mixed patterns (brachydactyly ectrodactyly), polymelia and polyphalangy.
