Cheviron, Angelo P. Pleistocene glacial cycles have often been hypothesized to provide vicariant mechanisms leading to allopatric speciation in a wide range of southern South American Fuegian and Patagonian avian taxa. Few of those biogeographic hypotheses, however, have been rigorously tested using phylogenetic analysis. We examined sequence variation in three mitochondrial gene fragments cytochrome bND2, and ND3 to construct a molecular phylogeny for the South American genus Geositta Furnariidae and to test the interrelated hypotheses that Geositta cunicularia and G.

Sequence data were obtained for all 10 currently recognized species of Geositta as well as Geobates poecilopterus and two outgroup taxa Upucerthia ruficauda and Aphrastura spinicauda. We found levels of sequence divergence among Geositta species to be high, ranging from 7. Our phylogenetic reconstructions clearly indicate relationships among Geositta species that differ considerably from those of traditional Geositta phylogeny.

These data also strongly suggest that Geosittaas currently defined, is what is meant by molecular phylogeny, with Geobates being embedded within Geositta. Our data do not support the hypothesized sister relationship between G. Instead, they suggest that Geositta consists of two distinct clades, with antarctica and cunicularia phylogejy into different clades.

The high levels of sequence divergence among Geositta species, lack of a sister relationship between cunicularia and antarcticaand placement of Fuego-Patagonian antarctica into a clade consisting of two high-Andean saxicolina and isabellina and molecularr coastal-west-slope maritima species demonstrate that the evolutionary history of Geositta is much older and far more complex than a simple model whah allopatric speciation in glacial refugia would bsc food science and technology scope.

Obtuvimos secuencias para las 10 especies de Geositta reconocidas en ohylogeny actualidad, así como para Geobates poecilopterus y para dos taxa considerados como grupo externo Upucerthia ruficauda y Aphrastura spinicauda. Encontramos phylogenh los niveles de divergencia entre las secuencias de especies de Geositta son altos, entre 7. Nuestras reconstrucciones filogenéticas claramente indican relaciones entre las especies de Geositta que difieren considerablemente de las sugeridas por la filogenia tradicional del género.
