A molecular phylogeny of the dove genus Zenaida: Mitochondrial and nuclearDNA sequences

We reconstructed a phylogeny for the seven species of doves in the genus Ze naida on the basis of a combined analysis of mitochondrial (ND2 and cytochr ome b) and nuclear (fibrinogen intron 7) DNA sequences. This phylogeny, whi ch is completely resolved, is well supported with all nodes showing greater than 50% bootstrap support. There was no significant conflict between tree s based on each gene independently, although trees produced from fibrinogen intron 7 did not resolve relationships among five of the Zenaida species. The species status of Z. graysoni, as well as that of Z. meloda, is suggest ed based on their divergence from sister taxa (about 1% and 4%, respectivel y) and other differences. Zenaida can be divided into two major groups: Zen aida asiatica and Z. meloda versus Z. aurita, Z. galapagoensis, Z. auricula ta, Z. graysoni, and Z. macroura.
