Phylogeny of the doi In view of the amount of adaptive radiation among ovenbirds, Furnariinae, the traditional taxonomy needs scrutiny. We used nuclear DNA data to study pphylogenetic of the genus Upucerthia.

Five species belong in the Furnariini, as traditionally assumed. The other species represent two independent cases of specialisation for terrestrial life, in response to formation of arid habitats in the southern Andes, within the paraphyletic assemblage of arboreal species referred to as Philydorini.

Nevertheless, the subdivision into used; Chesser b and Geositta with 10—11 species; ecologically distinctive sub-groups has been maintained with Cheviron et al. No clear-cut ; Dickinson ; Remsen Yet the inhabiting scrubby vegetation, and the Furnariini, which are molecular evidence now suggests that Geositta, along with rather stout birds of terrestrial habits, often associated with Sclerurus, represent an independent deep lineage outside the edges of streams.

Thus, a thorough assess- where the nucleotide could not be determined with certainty ment is needed of the relationship of Upucerthia species.

Nevertheless, most other discrepancies between the We were able to sequence all four gene regions almost com- gene trees mainly occur at weakly supported nodes less than pletely for all taxa, but in the ODC region, all sequences 0.

The tree obtained the exon 7, as we use overlapping primers to amplify the two from the combined analyses is also generally congruent with ODC fragments. The sequences obtained varied in length the tree presented by Irestedt et al. Thus, we will not comment on the Most indels observed in the introns were autapomorphic and poorly resolved early evolution of the Furnariinae as a whole, mainly found in particularly variable and repetitive regions.

A few indels harterti and certhioides are together, with strong support, and were also found to be incongruent with the phylogenetic tree usually with Premnornis and Pseudocolaptes as wuat sister clade, obtained from the analysis of the combined data set.

We expect DNA-based phylogenies to be good proxies for this kind of diversity, and these are much easier to generate. So, suppose we want to use our suggested measure to find the amount of unique evolutionary history contained in the birds or other focal group of a site.
