[Identification by starch gel electrophoresis of the species of lizards Lacerta muralis Laurenti 1768 and Lacerta hispanica Steindachner 1870 in the sympatric populations of Spain and Languedoc-Roussillon]. | An electrophoretic analysis of three enzymatic loci (Got-1, Ldh-A and Ldh-B) has shown that examination of Got-1 alleles allows unambiguous identification of L. muralis and L. hispanica in areas where the two species are sympatric and not identifiable by classical techniques of systematics. At the Ldh-A locus, one alle... | 816,551 | [
