Fig 1.
Comparison of PhyML results obtained from SNPs dataset (left) with the NJ tree (right) obtained using loci presence-absence data. Inset map shows the global distribution of Lithocarpus (blue+green) in reference to continental (blue) and insular (green) datasets. Clade colors and connecting lines indicate alternate placements of species in opposing trees. Numbers (right) and colors (left) on branches indicate nodal support values.
Fig 2.
Dated tree based on the reconstructed MIGseq loci (Penalized likelihood).
Nodes ages (in Ma) are indicated as well as the geographic range in the 2-zones configuration (tips of the branches, colors according to those in Fig 1).
Fig 3.
Density histogram of inter- and intra-zone distances according to study region (“continent” or “island”).
Inter-zone distance: red; intra-zone distance: blue. Species found in both continental and island areas were excluded. For each plot the corresponding count histogram is plotted as inset.
Fig 4.
Box plot comparisons of herbarium and silica sample characteristics for statistics derived from ipyrad analyses.
Herbarium material: left, red; silica materials: right, green (see also S6 Fig).
