Heart-lactate dehydrogenase: An allozyme marker differentiating Lacerta trilineata Bedriaga, 1886, and Lacerta viridis (Laurenti, 1768) in Southern Europe

Abstract

37 specimens of Lacerta trilineata and 40 of Lacerta viridis, as well as one hybrid (bred in captivity), were electrophoretically investigated at 16 Genetic loci. The only constant difference was the mobility of the heart LDH. In contrast to the often uncertain morphological differences of species, this protein can be used for the clear identification of both species and possible hybrids. To identify the species (without destroying the animals) only pieces of lizard tails soaking them in PPS and running LDH gels are necessary. The method is discussed in full.
