Lineage diversity in a widely distributed New World passerine bird, the House Wren
Abstract We explored the evolutionary radiation in the House Wren complex (Troglodytes aedon and allies), the New World’s most widely distributed passerine species. The complex has been the source of ongoing taxonomic debate. To evaluate phenotypic variation in the House Wren complex, we collected 8...

MtDNA data show a paraphyletic arrangement of T. a. musculus on the tree, whereas the SNP tree portrays them as monophyletic.

Although we had only mtDNA data for T. a. martinicensis from the Lesser Antilles, we found at least 4 distinct and paraphyletic taxa from Trinidad, Granada, St. Vincent islands, and Dominica. The House Wren complex showed strong differentiation in mtDNA and RADseq datasets, with conflicting patterns likely arising from some combination of sex-biased dispersal, incomplete lineage sorting, or selection on mtDNA. The most glaring discrepancies between these 2 datasets, such as the paraphyly of eastern and western North American House Wrens in the mtDNA tree, present excellent opportunities for follow-up studies on evolutionary mechanisms that underpin phylogeographic patterns.
