Protein variation and its systematic implications for the South African Leporidae (Mammalia:Lagomorpha)

Analysis of 9 genetic loci by horizontal starch gel electrophoresis was performed on 203 specimens of South African representatives of the leporid genera Lepus and Pronolagus. Three loci were found to be polymorphic within samples of the various species of both genera: transferrin (Tf-I), esterase-1 (Es-I) and esterase-2 (Es-II). Only one system, carbonic anhydrase (CA-I), proved useful in species identification, this being restricted to the genus Lepus. Based on this system all Lepus specimens analysed would be assigned to one of two groups corresponding to the species L. capensis and L. saxatilis.
