Data from: Comparison of target-capture and restriction-site associated DNA sequencing for phylogenomics: a test in cardinalid tanagers (Aves, genus: Piranga)
Restriction-site associated DNA sequencing (RAD-seq) and target capture of specific genomic regions, such as ultraconserved elements (UCEs), are emerging as two of the most popular methods for phylogenomics using reduced-representation genomic datasets. These two methods were designed to target different evolutionary timescales: RAD-seq was designed for population-genomic level questions and UCEs for deeper phylogenetics. The utility of both datasets to infer phylogenies across a variety of taxonomic levels has not been adequately compared within the same taxonomic system. Additionally, the effects of uninformative gene trees on species tree analyses (for target capture data) have not been explored. Here, we utilize RAD-seq and UCE data to infer a phylogeny of the bird genus Piranga. The group has a range of divergence dates (0.5 my – 6 my), contains eleven recognized species, and lacks a resolved phylogeny. We compared two species tree methods for the RAD-seq data and six species tree methods for the UCE data. Additionally, in the UCE data, we analyzed a complete matrix as well as datasets with only highly informative loci. A complete matrix of 189 UCE loci with ten or more parsimony informative (PI) sites, and an ~80% complete matrix of 1128 PI SNPs (from RAD-seq) yield the same fully resolved phylogeny of Piranga. We inferred non-monophyletic relationships of P. lutea individuals, with all other a priori species identified as monophyletic. Finally, we found that species tree analyses that included predominantly uninformative gene trees provided strong support for different topologies, with consistent phylogenetic results when limiting species tree analyses to highly informative loci or only using less informative loci with concatenation or methods meant for SNPs alone.

FIGURE 1 in A new genus and species of tanager (Passeriformes, Thraupidae) from the lower Yungas of western Bolivia and southern Peru
FIGURE 1. Phylogenetic analyses of the new species and relatives using separate gene trees (ND2, cyt b, ACO1, and Rag1) and combined analyses (Concatenated, *Beast). Support values (posterior probabilities) are shown at each node. All trees strongly support the placement of the new species in a clade with Eucometis penicillata and Trichothraupis melanops. However, the trees disagree on the relationships of these taxa relative to each other, and none of the trees show strong support for relationships among these three taxa, emphasizing the distinctness of these three species relative to each other.

FIGURE 2. Phylogenetic analyses of the new species and close relatives based on UCE loci. Support values for each node shown for RAxML, SVDQuartets, and ASTRAL. There is strong support for a clade containing the new species, Trichothraupis melanops, and Eucometis penicillata. Within this clade, T. melanops is identified as the closest living relative to the new species. Although strongly supported, the branch connecting the clade comprising the new species and T. melanops is short. Thumbnail illustrations of the birds by DFL.
