Table 4. Spearman's rank order correlations (ρ) between constitutive levels of six immune traits and number of diseases affecting each species and average prevalence (proportion of infected individuals on a population of a given species) of all diseases affecting each species, at three taxonomic levels (family, genus and species) among 14 scleractinian coral species from the Caribbean (significant correlations are bolded).
