Figure 3 from: Wonglersak R, Cronk Q, Percy D (2017) Salix transect of Europe: structured genetic variation and isolation-by-distance in the nettle psyllid, Trioza urticae (Psylloidea, Hemiptera), from Greece to Arctic Norway. Biodiversity Data Journal 5: e10824. https://doi.org/10.3897/BDJ.5.e10824

Figure 3 - The ML tree of 82 samples along the transect showing bootstrap support values. Four regional clades are identified (southern, central, northern, arctic) and the clade position of the non-included western European samples is indicated. Stars indicate the position of individuals within regional clades but not from that region (see also MP and haplotype network in Figs 2, 5, 6).
