Figure 4. Clade 3 of the genus Ophiognomonia. Spatial evolutionary and ecological vicariance analysis (SEEVA) results. Divergence indices of four host plant variables: host plant order, family, genus, and species. Histograms of divergence indices (0–1) for each variable are mapped onto the maximum-likelihood tree from the GARLI analysis for 17 species of Ophiognomonia. After applying a Bonferroni correction (P ≤ 0.0034), the statistically significant divergence indices are indicated by asterisks at each node (*). Nodes are labelled as clade #:node #. The host plant families are represented as shaded boxes. The complete host–fungus associations are listed in Table 1. Patterns of host conservatism, specialization, or switching are indicated by bold arrows. Nodes 3:3, 3:4, 3:5, 3:9, 3:11, 3:12, 3:13, and 3:14 are not supported by maximum-likelihood bootstrap values of ≥ 70%.
