| Resumo: | Partial DNA sequences from two mitochondrial (mt)
and one nuclear gene (cytochrome b, 12S rRNA, and
C-mos) were used to estimate the phylogenetic relationships
among the six extant species of skinks endemic
to the Cape Verde Archipelago. The species
form a monophyletic unit, indicating a single colonization
of the islands, probably from West Africa.
Mabuya vaillanti and M. delalandii are sister taxa, as
indicated by morphological characters. Mabuya fogoensis
and M. stangeri are closely related, but the
former is probably paraphyletic. Mabuya spinalis and
M. salensis are also probably paraphyletic. Within species,
samples from separate islands always form monophyletic
groups. Some colonization events can be hypothesized,
which are in line with the age of the
islands. C-mos variation is concordant with the topology
derived from mtDNA. |
