“…Even so, one characteristic in all these cases is the absence of reciprocal monophyly in the mitochondrial genealogy of the lineages, which would be consistent with ILS (McKay & Zink, ), although this is not true of the pattern found in the B and C lineages (Figure ). However, more recent studies have indicated that the disagreement between mitochondrial and nuclear phylogenies may be a consequence of past introgression events that resulted in the sequestering of the mtDNA of the established populations (Ferreira et al, ; Sullivan et al, ). In this case, with sufficient divergence time, unrelated lineages in a multilocus species tree may become more closely related from a mitochondrial perspective.…”

We used molecular tools and a multilocus approach to investigate the phylogeography of Lepidothrix coronata across most of its ample range. We sequenced six DNA fragments to produce phylogenies, molecular dating estimates, analyses of the dynamics of the demographic history of the species and a biogeographic analysis to estimate the events and changes in the ancestral distribution of the species. The results indicated the presence of four well‐established lineages, with high levels of divergence. These lineages are delineated by well‐defined geographic barriers, with one lineage, restricted to the west of the Andes, being the first to diverge from the complex. The other three lineages are exclusive to the Amazonian distribution of the species, with two being found north of the Amazon River, and the third, south of the Amazon. Some of the relationships found between these lineages were distinct from those described in previous studies. Important disagreements were found between the mtDNA phylogeny and that of the multilocus analysis, in relation to the lineages located to the west of the Andes. We propose that past introgression events may have influenced shifts in the relationships between lineages, despite the fact that the groups were well defined in both the phylogenies. The biogeographic analysis indicates that the lineages arose through successive vicariance events, which had a primary role in the diversification of the group. Two or three genetically structured subclades were also found within each Amazonian lineage, although these subclades are not isolated by an obvious geographic barrier.

“…If nuclear sequence data disagree with the mitochondrial data we present, the first hypothesis could easily account for this pattern through gene flow and mitochondrial capture from one species to the other (e.g. Hird & Sullivan 2009, Irwin et al 2009, Ferreira et al 2018. Expanded geographic sampling, particularly from western populations of E. papuana in the Bird's Head region of New Guinea will be necessary to fully explore this hypothesis.…”

“…Another possible explanation to the nuclear-mitochondrial discordance may be a mitochondrial capture event early in the evolution of the family (cf. Ferreira et al 2018 ), but the fact that the rooting depends on which codon positions are analyzed makes saturation more likely.…”

Parallel Evolution of Bower-Building Behavior in Two Groups of Bowerbirds Suggested by Phylogenomics

et al. 2020

Abstract The bowerbirds in New Guinea and Australia include species that build the largest and perhaps most elaborately decorated constructions outside of humans. The males use these courtship bowers, along with their displays, to attract females. In these species, the mating system is polygynous and the females alone incubate and feed the nestlings. The bowerbirds also include 10 species of the socially monogamous catbirds in which the male participates in most aspects of raising the young. How the bower-building behavior evolved has remained poorly understood, as no comprehensive phylogeny exists for the family. It has been assumed that the monogamous catbird clade is sister to all polygynous species. We here test this hypothesis using a newly developed pipeline for obtaining homologous alignments of thousands of exonic and intronic regions from genomic data to build a phylogeny. Our well-supported species tree shows that the polygynous, bower-building species are not monophyletic. The result suggests either that bower-building behavior is an ancestral condition in the family that was secondarily lost in the catbirds, or that it has arisen in parallel in two lineages of bowerbirds. We favor the latter hypothesis based on an ancestral character reconstruction showing that polygyny but not bower-building is ancestral in bowerbirds, and on the observation that Scenopoeetes dentirostris, the sister species to one of the bower-building clades, does not build a proper bower but constructs a court for male display. This species is also sexually monomorphic in plumage despite having a polygynous mating system. We argue that the relatively stable tropical and subtropical forest environment in combination with low predator pressure and rich food access (mostly fruit) facilitated the evolution of these unique life-history traits.
