The correlation was tested separately for the eight lineages comprising at least five species and involved in at least 10 inferred HTT events. Lineages are named after a representative genus (Fig. S1).
Transfers may represent either direct or indirect HTT (main text), and a given transfer may be used in more than one correlation test (row).
The denominator is the number of species in each lineage.
Correlations were assessed by Spearman rank tests, and a P value corresponds to the risk of inferring a negative correlation while there is none.
