Figure 3 in Molecular systematics of the world's most polytypic bird: the Pachycephala pectoralis/melanura (Aves: Pachycephalidae) species complex
Figure 3. Molecular phylogeny of outgroup Pachycephala species. The tree is the Bayesian maximum consensus tree from the concatenated, partitioned analysis. Node support is denoted as Bayesian posterior probabilities (above) and maximum likelihood bootstrap support (below). Sequences of taxa labelled with '(GB)' were downloaded from GenBank. The ingroup is collapsed into two triangles, represented here by clades B and C. The ingroup phylogeny is depicted in Figure 2.

Letters represent the area units defined in Table 5 and in Fig. 23: letter combinations in grey below terminals show species' current distributions; letter combinations above the nodes show the most likely reconstructions for ancestral distributions (with four selected dispersal events numbered), with the probabilities of these solutions for these ancestors shown below the nodes. Species groups discussed in the text are labelled in circles: rp = rufipes-group; fs = festivus-group; rf = rufofasciatus- group; tg = tanguticus-group; la = lapidarius-group; si = sichelii-group; and ke = keriensis-group. Inset map shows sequenced samples for the species groups (blue = the rufipes-group and festivus-group; green = the rufofasciatus-group; yellow = the tanguticus-group and lapidarius-group; orange = the sichelii-group; and red = the keriensis-group) with arrows showing the four numbered dispersal events.

Tuning adatom mobility and nanoscale segregation by twin formation and polytypism
<p>Nanoscale variations in the composition of an AlxGa1−xAs shell around a GaAs nanowire affect the nanowire<br> functionality and can lead to the formation of localized quantum emitters. These composition<br> fluctuations can be the consequence of variations of crystal phase and/or nanoscale adatom<br> mobility.By applying electron microscopy related techniques we correlate the optical,<br> compositional and structural properties at the nanoscale on the same object. The results indicate a<br> clear correlation between the twin density in the nanowire and the quantum-emitter density as<br> well as a significant redshift in the emission. We propose that twinning increases nanoscale<br> segregation effects in ternary alloys. An additional redshift in the emission can be explained by<br> the staggered band-alignment between wurtzite and zinc-blende phases. This work opens new<br> avenues in the achievement of homogeneous ternary and quaternary alloys in nanowires and in<br> the engineering of the segregation effects at the nanoscale.</p>
