Abstract
Analysis for genetic variation of insular and mainland populations ofEulemur macaco has revealed: (1) a different degree of genetic variation between populations; and (2) the phylogenetic relationships between groups, on the islands of Nosy-Be and Nosy-Komba, and in the Peninsula of Ambato (Madagascar). Eleven systems of blood proteins from 157 animals were used as genetic markers. The genetic variation was lower on the island of Nosy-Komba than in the mainland of Ambato. This is consistent with the expectation that genetic variation is lower on islands than on mainlands. In contrast, the genetic variation on the island of Nosy-Be was the highest of the three populations. This finding can best be explained by assuming that the sample of Nosy-Be consists of individuals of several small isolated groups, where genetic drift computation showed the population of Nosy-Be to be distinct, and the populations of Nosy-Komba and Ambato to be close within the same branch of the dendrogram. These findings give an insight into the population history of the island of Nosy-Komba, which might have been populated by mainland groups from Ambato.
