Table 7 The result of nested clade phylogeographic analysis of Begonia luzhaiensis based on trnC-ycf6 haplotypes

From: Phylogeography of Begonia luzhaiensis suggests both natural and anthropogenic causes for the marked population genetic structure

Clade Significant clades and I-T Significant parameter Phylogeographic inferences
1-1 H8 (I) H9 (T) I-T Dc> ; Dn> Dc> ; Dn> 1 → 2→3 → 4→No: Restricted gene flow with isolation by distance
1-2 H6 (I) H7 (T) I-T Dn> Dc< ; Dn< Dc> ; Dn> 1 → 19 → No: Allopatric fragmentation
1-3 H2 (I) H3 (I) H4 (T) Dc< ; Dn< Dc< ; Dn> Dc< 1 → 19 → No: Allopatric fragmentation
2-1 1-1 (T) 1-2 (I) I-T Dc< ; Dn< Dc< ; Dn> Dc> ; Dn> 1 → 2→3 → 5→15 → No → 21 → No: past gradual range expansion followed by fragmentation or a past larger range followed by extinction in intermediate areas
2-2 1-3 (I) 1-4 (T) 1-5 (T) I-T Dn> Dc< ; Dn< Dc> 1 → 2→3 → 5→15 → No → 21 → No: past gradual range expansion followed by fragmentation or a past larger range followed by extinction in intermediate areas
Total 2-1 (T) 2-2 (T) Dc< ; Dn< Dc< ; Dn> 1 → 19 → No: Allopatric fragmentation
  1. Phylogeographic inferences are inferred by applying the inference key of Posada et al. (2000) (http://darwin.uvigo.es/software/geodis.html)
  2. (T): tip; (I): interior; Dc: clade distance; Dn: nested clade distance; I-T: interior vs. tip clades
