Data from: Exploring conflicts in whole genome phylogenetics: A case study within Manakins (Aves: Pipridae)
<p>Some phylogenetic problems remain unresolved even when large amounts of sequence data are analyzed and methods that accommodate processes such as incomplete lineage sorting are employed. In addition to investigating biological sources of phylogenetic incongruence, it is also important to reduce noise in the phylogenomic dataset by using an appropriate filtering approach that addresses gene tree estimation errors. We present the results of a case study in manakins, focusing on the very difficult clade comprising the genera <em>Antilophia</em> and <em>Chiroxiphia</em>. Previous studies suggest that <em>Antilophia</em> is nested within <em>Chiroxiphia</em>, though relationships among <em>Antilophia</em>+<em>Chiroxiphia</em> species have been highly unstable. We extracted more than 11,000 loci (ultra-conserved elements and introns) from whole genomes and conducted analyses using concatenation and multi-species coalescent methods. Topologies resulting from analyses using all loci differed depending on the data type and analytical method, with two clades (<em>Antilophia</em>+<em>Chiroxiphia</em> and <em>Manacus</em>+<em>Pipra</em>+<em>Machaeopterus</em>) in the manakin tree showing incongruent results. We hypothesized that gene trees that conflicted with a long coalescent branch (e.g., the branch uniting <em>Antilophia</em>+<em>Chiroxiphia</em>) might be enriched for cases of gene tree estimation error, so we conducted analyses that either constrained those gene trees to include monophyly of <em>Antilophia</em>+<em>Chiroxiphia</em> or excluded these loci. While constraining trees reduced some incongruence, excluding the trees led to completely congruent species trees, regardless of the data type or model of sequence evolution used. We found that a suite of gene metrics (most importantly the number of informative sites and likelihood of intralocus recombination) collectively explained the loci that resulted in non-monophyly of <em>Antilophia</em>+<em>Chiroxiphia</em>. We also found evidence for introgression that may have contributed to the discordant topologies we observe in <em>Antilophia</em>+<em>Chiroxiphia</em> and led to deviations from expectations given the multi-species coalescent model. Our study highlights the importance of identifying factors that can obscure phylogenetic signal when dealing with recalcitrant phylogenetic problems, such as gene tree estimation error, incomplete lineage sorting and reticulation events.</p>

Systematics of Lepidothrix manakins (Aves: Passeriformes: Pipridae) using RADcap markers
<p>Although recent molecular phylogenetic analyses of<b> </b><em>Lepidothrix</em> manakins (family Pipridae) have helped clarify their evolutionary relationships, the placement of several lineages remains in question because of low or conflicting branch support. In particular, the relationship of <em>L. coronata</em> to other members of the genus and relationships within the <em>L. nattereri</em>+<em>L. vilasboasi</em>+<em>L. iris</em> clade have been difficult to resolve. We used RADcap to collect restriction site-associated DNA sequence data and estimate the first subspecies-level phylogeny of the genus <em>Lepidothrix</em> (17 of 18 currently recognized subspecies), and we included extensive geographic representation of the widespread and phenotypically variable <em>L. coronata</em>. We found strong support for the phylogenetic position and monophyly of <em>L. coronata</em>, and we resolved two clades separated by the Andes that, along with previous divergence time estimates and our assessment of morphological and vocal evidence, suggest the presence of two biological species: Velvety Manakin (<em>L. velutina</em>) west of the Andes and Blue-capped Manakin (<em>L. coronata</em>) east of the Andes. Species-level relationships within the <em>L. nattereri+L. vilasboasi+L. iris</em> clade remained poorly resolved in concatenated and coalescent-based analyses, with SNAPP analyses suggesting that the lack of reciprocal monophyly is due to extensive allele sharing among these taxa. Finally, we confirmed a previously documented hybrid between <em>L. coronata</em> and <em>L. suavissima</em> as an F1 individual, consistent with the view that hybridization between these two species is a rare event and that postmating reproductive barriers prevent successful backcrossing.</p>

FIGURE 5. A comparison of the shapes of the outer two primaries of adult male Machaeropterus r. regulus (A, AMNH 493126) and M. r. striolatus (B, LSUMZ uncataloged, GFS 465).

Lane, XC170145). B) M. eckelberryi (PERU: San Martín dept.; Morro de Calzada, ca. 1000m. 29 July 2005. D. F. Lane, XC170143). C) M. regulus striolatus (PERU: Loreto dept.; Jeberos, ca. 350m. 15 June 2001. D. F. Lane, XC170138). D) M. r. striolatus (PERU: Loreto dept.; Oran, ca 200m. 24 July 2013. D. F. Lane, XC170139). E) M. r. aureopectus (VENEZUELA: Bolivar state; El Pauji. 4 December 2010. A. Renaudier, XC66415). F) M. r. antioquiae (COLOMBIA: Santander dept.; Serranía de la Quinchas, RNA El Paujíl. F. Lambert, XC16781). G) M. r. regulus (BRAZIL: Rio de Janeiro; Reserva Ecológica de Guapiaçu. J. Minns, XC82253). Notice the light flat lines (around 1kHz and 3 kHz) "underscoring" the notes of the songs in figures C-G, but lacking in A and B. Also note that the song of M. r. antioquiae (F) is very similar in structure to those of M. r. striolatus (C, D), but the spacing between the two main notes is longer. The dark band running above the loudest fundamental frequencies of the notes in C and D is insect noise. "XC####" refers to recordings available at www.xeno-canto.org/####.
