  1. Log Likelihood values (log Lik), Akaike's information criteria (AIC), change in AIC score (Δi), and AIC weight (wi) for the top four of 26 candidate models relating host longevity (Long), estimates of global population size (GlobPop), geographic range (GeoRange), clutch size (ClutchSize) and the four principal component (see Table 4) to the raw values of parasite taxonomic richness (PTR). Sampling effort (Google Scholar citations) was included as an asymptotic variable in all the models shown in this table by using the residuals. * denote variables that were significant in the focused tests.
