- Relaciones filogenéticas entre géneros de ciervos neotropicales (Artiodactyla: Cervidae) mediante secuenciación de ADN mitocondrial y marcadores microsatelitales Ettore Randi María Martínez-Agüero Manuel Ruiz-García Diana Alvarez Biología DNAmt Mazama Odocoileus microsatellites neotropical deers Phylogenetic relationships among Neotropical deer genera (Artiodactyla: Cervidae) by meansof DNAmt sequences and microsatellite markers. The current work shows two molecular phylogeneticanalyses on Neotropical deers. In the first analysis, the mitochondrial control region (D-loop) was sequencedin six Odocoileinae species from Latin America, using the sequences of two Muntiacinae as outgroups. Theresults obtained were as follows: A sequence of Mazama americana showed a striking relationship with severalsequences of Odocoileus in contrast to that expected, since this M. americana haplotype, from a Mexican origin,was not associated with several Bolivian Mazama sequences analyzed. This could put forward that this generais not monophyletic. On the other hand, these Bolivian Mazama formed a clade with Pudu puda and Ozotocerosbezoarticus. Likely, an Odocoileus virginianus sequence from the Central area of Colombia showed a morestrong relationship with a Northamerican O. heminonus sequence than with the other O. virginianus sequencesof Colombian origin as well. This could be explained by means of various different hypotheses. The first is theexistence of common ancestral haplotypes between both species. Another one is the reiterative hybridizationamong both Odocoileus species before the migration of O. virginianus from North America to South America.Moreover, the maximum parsimony analysis showed an intense relationship between the Muntiacinae and thisNeotropical Cervidae clade. In addition, and adding credence to the relevant polyphyletism found in Mazamaby means of the mitochondrial control region DNA sequences, a second analysis with 16 DNA microsatelliteloci also showed a higher genetic relationship between M. americana and O. virginianus, than between the firstspecies regard to Mazama gouazoubira.
