Abstract

In this study, we apply a genome–scale set of molecular markers, ultraconserved elements, to fully resolve the phylogeny of a family of secretive, nocturnal birds, the potoos (Nyctibiidae). This dataset provides an opportunity to explore some challenges of phylogenetic analysis of genome–scale datasets, which we address in several ways. We generate data matrices ranging between 2,610–4,175 loci (1,477,319–3,848,295 aligned base pairs) that represent versions of the data differing in whether or not alignments were trimmed prior to concatenation, and whether 100% or 75% of all taxa were required to be present for inclusion of a given locus. These matrices are analyzed with both maximum likelihood and coalescent algorithms, to check for artifacts of concatenation. Then, we subsample our data matrix into randomly–selected replicates between 125–1,000 loci, and compare the statistical support of the resulting trees to look for evidence of systematic error. In analyses of complete matrices, we find strong statistical support for all ingroup nodes with no evidence for systematic error introduced by alignment trimming, missing data, or concatenation, and we find further support for that topology in our subsampling analyses and statistical topology tests. Finally, we compare our strongly supported topology to those of previous studies, and use the phylogeny to examine the evolutionary history of potoos.
