Fig. 7 in Using RADseq to resolve species boundaries in a morphologically complex group of yellow-flowered shrubs (Geleznowia, Rutaceae)

Fig. 7. SVDquartets trees for Geleznowia and two outgroup taxa on the basis of 3338 SNPs. Coloured numbers correspond to genomic groups in the PCA and are coloured by initial morphological identification, and colours of clades match colours in the Structure figure. (a) Lineage tree with individuals represented by a single sequence. Monophyletic groups are collapsed for clarity and labelled with population numbers. Bootstrap support values less than 100 are shown above branches. Pie charts at nodes of interest show site concordance factors: the proportion of informative sites supporting the given branch topology (white) and the two alternative topologies (grey and black). One sample from Group 1 that is placed strangely is indicated with an asterisk (*) in (a) and (b). (b) Consensus network of bootstrap trees for the lineage analysis, showing splits found in at least 10 of the 100 trees. Branch lengths are proportional to bootstrap value; values are omitted for 100 and <20%. (c, top) Species tree with individuals grouped into putative 'species' (genomic groups from the PCA plus the divergent populations P4 and P9). Bootstrap support values less than 100 are shown above branches. (c, bottom) Consensus network of bootstrap trees for the species analysis, showing splits found in at least 10 of the 100 trees. Branch lengths are proportional to bootstrap value; values are omitted for <20%.
