FIGURE 3 in Taxonomic revision of Myrmeciza (Aves: Passeriformes: Thamnophilidae) into 12 genera based on phylogenetic, morphological, behavioral, and ecological data
FIGURE 3. Simplified time-calibrated chronogram of the Thamnophilidae showing relative ages of former members of the genus Myrmeciza and the main radiations in the family. Estimated stem ages of newly designated monotypic genera suggest that they diverged long ago from their closest relatives and provide additional support for their phenotypic, ecological, and behavioral distinctiveness. Bars at nodes indicate the 95% highest posterior density for the inferred divergence time estimates (Bravo 2012).
FIGURE 2 in Taxonomic revision of Myrmeciza (Aves: Passeriformes: Thamnophilidae) into 12 genera based on phylogenetic, morphological, behavioral, and ecological data
FIGURE 2. Bayesian consensus tree of a subset of the Thamnophilinae, showing that Myrmeciza is polyphyletic (species names in these clades are emboldened). Members of Myrmeciza are placed in eight different well-supported clades in the Microrhopiini, Pithyini, and Pyriglenini. The color of the circles at nodes indicates posterior probability support,> 0.95 (black), 0.95–0.75 (gray), <0.75 (white).

Recent population differentiation in the habitat specialist Glossy Antshrike (Aves: Thamnophilidae) across Amazonian seasonally flooded forests: Complete matrix
<p>We assessed population structure and the spatio-temporal pattern of diversification in the Glossy Antshrike <i>Sakesphorus luctuosus</i> (Aves, Thamnophilidae) to understand the processes shaping the evolutionary history of Amazonian floodplains and address unresolved taxonomic controversies surrounding its species limits. By targeting ultraconserved elements (UCEs) from 32 specimens of <i>S. luctuosus</i>, we identified independent lineages and estimated their differentiation, divergence times and migration rates. We also estimated current and past demographic histories for each recovered lineage. We found evidence confirming that <i>S. luctuosus</i> consists of a single species, comprising at least four populations, with some highly admixed individuals and overall similar levels of migration between populations. We confirmed the differentiation of the Araguaia River basin population (<i>S. l.</i> <i>araguayae</i>), and gathered circumstantial evidence indicating that the taxon <i>S. hagmanni</i> may represent a highly introgressed population between 3 distinct phylogroups of <i>S. luctuosus</i>. Divergence time estimates between populations seem to be recent, occurring during the last 183 kya. Signs of population expansions were detected for populations attributed to subspecies <i>S. l. luctuosus</i>, but the <i>S. l. araguayae </i>population had probably maintained its effective size through time. Our results support<b> </b>that <i>S. luctuosus</i> has had a complex population history, resulting from a high dependence on southeastern "clear-water" habitats and their availability through time. Spatial and demographic expansions towards the western "white water" flooded forests might still be ongoing. Our study reinforces the view that isolation due to absence of suitable habitat has been an important driver of population differentiation within Amazonian flooded forests, but also that differences between <i>várzeas</i> ("white water" floodplains, mostly in southwestern Amazonia) and <i>igapós</i> ("clear- water" floodplains, especially located in the east) should be further explored as powerful drivers of micro-evolution.</p>
