Table 4 Results of the Shimodaira-Hasegawa (SH) test indicate the data cannot reject any of the 15 alternative rooted Blochmannia phylogenies.

From: One nutritional symbiosis begat another: Phylogenetic evidence that the ant tribe Camponotini acquired Blochmanniaby tending sap-feeding insects

  1. 1Each of the three unrooted trees (A-C, see Figure 4) has five possible root positions, for 15 possible rooted trees.
  2. 2The root position indicates the lineage to which outgroup taxa (mealybug endosymbionts) were attached, with "mid" indicating the internal branch.
  3. 3Non-significant results indicate that the likelihood score does not differ significantly from that of the "best" tree (topology A-Colob).
