Malate dehydrogenase (sMDH) in Amazon cichlid fishes: evolutionary features
1. 1. The sMDH isozyme system was studied in five species of cichlid fishes found in the Amazon hydrographic basin (Astronotus ocellatus, Cichla monoculus, Geophagus cff harreri, Cichlassoma severum and Mesonauta insignis). All studied specimens presented a six-banded electrophoretic pattern, sugges...
