  abstract = {{D}ata on parasites of {M}editerranean {S}ea fishes, collected from previous published surveys, were used to test 5 hypotheses concerning the determinants of parasite species richness. {A} total of 170 parasite species belonging to 5 distinct taxonomic groups (nematodes, acanthocephalans, digeneans, monogeneans and crustaceans) were identified from 79 marine fish species (3904 individuals) collected at a regional scale. {F}ive independent variables concerning host life traits (body size, diet, range, abundance and schooling) were investigated and controlled for host sampling effort. {A} comparative analysis using the independent contrasts method was conducted in order to avoir phylogenetic confounding effects. {W}e demonstrate the importance of taking host sampling effort into account when investigating the determinants of parasite species richness. {M}onogeneans were the only group for which the species richness showed a significant correlation with some of the variables studied. {P}arasite species richness of monogeneans was positively correlated with host body size and negatively correlated with host species abundance. {T}he positive relationship between fish body size and the number of parasite species on a regional scale may be explained by the hypothesis that larger host body size increases host vagility which in turn enhances exposure to more and more parasite species. {O}ur findings disagree with previous studies that did not take either phylogenetic confounding effects or geographic scale into account. {W}e demonstrate the importance of using phylogenetic information in comparative analyses by showing that fish body size was not correlated with geographical range when using phylogenetic independent contrasts. {W}e also suggest that studying parasites of host species from the same geographical region avoids the problem of confounding various assemblages of hosts with distinct histories.
