Nearly all cottontails were infected with at least I Eimeria species, with bimonthly prevalence ranging from 0-6-3% (E. leporis) to 42-9-89.3% (E. environ). Bavesian model averaging and multivariate techniques were used to investigate the relationships between the occurrence of each parasite and the structure of the relative community. Among the host parameters, only sex was found to be associated with the prevalence of E. honessi, while the rest of the parameters were only weakly correlated with prevalence and species richness. This indicates that individual phenotypic host characteristics are probably less important than environmental factors in determining levels of parasite prevalence and diversity. The community of Eimeria species was probably structured by competition, with less species co-occurrence than expected under a null hypothesis. This was made evident by the low co-occurrence of E. cm-iron and PS. neoirresidua with E. poudrei, E. honessi, and E. major.
