Visualization of the correlation matrix of four kinds of host specificity, divergence time, and p values of host-parasite individual links. Blue: a positive correlation; red: a negative correlation. SPSi: phylogenetic host specificity; PBSi: phylobeta host specificity; ntaxa: basic host specificity; contributions: p values of host-parasite individual links; BSi: geographic host specificity; divergence: divergence time of gyrodactylids
