Abstract: | A study of ten erythrocyte enzymes (PGM I, II, III, G6PD, 6PGD, GLO I, ADA, Est D, DIA, AcP, CA II, and AK) performed on 89 wild and 32 captiveEulemur macaco macaco shows that most systems are monomorphic except four (GLO I, CA II, 6PGD, and NADH DIA). The polymorphism of these markers allows us to make a satisfactory analysis of the variability on this species, especially on the view of comparing wild and captive populations, and shows that: (1) the population does not contain all phenotypes existing in the wild CAa, CAa + b, DIAIV, GLO IB − C, and PGDc are completely absent in all captive populations and DIAIII + IV is only present in three out of 32 animals; (2) in the Nosy-komba Island, the PGDc and DIAIV are absent and DIAIII + IV and GLO IB − C are only present in 1 out of 46 analyzed samples, showing that this population constitutes an isolate. The possibility to use these data for a strategy of Lemur conservation is discussed. |
