We used nuclear DNA data to study relationships 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.

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. There is also Molecular studies Irestedt et al. However, certain species have been moved in the Synallaxini Irestedt et al.
Positions about the monophyly of that genus. Thus, a thorough assess- where the nucleotide could not be determined with certainty ment is needed of the relationship of Upucerthia species. GenBank order to relate adaptive shifts in the Furnariinae to events in accession numbers are given in Table 1. For other primers, in or behind low scrubs at the what are sister groups on a phylogenetic tree disturbance.

All chains were run for 10 million genetic context, we included representatives from all main generations, with trees sampled every th generations.

For each gene and taxon, multiple pairwise comparisons is References: 1 Irestedt et al. The three specimens for which no voucher exist are marked with an asterisk. However, the split between suboscines and intron 2 in passerines: 0. PATHd8 is a non-parametric method, the combined data set were based on a total of 80 samples, which smoothes substitution rates sequentially by taking respectively.

However, this data set has few variable positions and an considering that these branch-lengths probably represents odd placement of the root in this tree could most likely be short time or uncertainties in the phylogeny or both. 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 What are sister groups on a phylogenetic tree as their sister clade, obtained from the analysis of the combined data set.

We applied a partitioned analysis of the combined complex is robustly nested in the Furnariini, along with data set, but since the same substitution model was selected Furnarius, Lochmias, Limnornis and Phleocryptes see Olson et al. They suggest together in the combined analysis. Posterior probability values are indicated below the nodes.
