| dc.description.resumen | Nothofagus Bl. is considered a key Gondwanan genus with a vicariate distribution that has attracted considerable interest from biogeographers, not only for the living species, but also due to its extensive fossil record. Relationships of living taxa are somewhat resolved, and morphological and molecular data support the recognition of four clades within the genus Nothofagus. However, relationships with fossil taxa are far from resolved. In fact, phylogenetic studies on Nothofagaceae rarely incorporate fossil species and, if they are included, only few foliar characters are codified in the datasets. Therefore, a cladistic analysis including all the Nothofagus species recognized for South America, and incorporating an important number of foliar characters (39), was made in order to explore these relationships. Seventy one morphological characters were scored for 19 extant and 13 fossil Nothofagus species from Argentina and Chile, three Fagus spp. and Betula pendula Roth as outgroup. Different search strategies were performed using TNT 1.5: Equal Weight and Implied Weight, and including or not a molecular constraint. The four subgenera of Nothofagus are recovered in all the searches, but, in most of them, several fossil taxa are recovered outside the Nothofagus clade. This preliminary result may suggest that many fossil putative Nothofagus may not belong in the family, and that characters used in the recognition of fossil representatives of the genus Nothofagus should be re-evaluated. New approaches will be explored in order to elucidate the relationships in the group. | es_ES |
