Abstract: One of the unresolved issues in the ecology of parasites is the relationship between host specificity and performance. Previous studies tested this relationship in different systems and obtained all possible outcomes. This led to the proposal of two hypotheses to explain conflicting results: the trade-off and resource breadth hypotheses, which are treated as mutually exclusive in the literature and were corroborated by different studies. In the present study, we used an extensive database on avian malaria from… Show more

“…Perhaps more importantly, a highly dynamic ecoevolutionary scenario where macroevolutionary patterns are only one of its outcomes is depicted, demanding to focus on the dynamics of these unexpected associations. In fact, we found a host-symbiont scenario in highly host-specific symbionts compatible with a geographic mosaic of coevolution in which network modules may be informative of the coevolutionary and codiversification dynamics (Thompson 1994(Thompson , 2005Poulin, 2010;Clayton et al, 2016;Ivens, Beeren, Blüthgen, & Kronauer, 2016;Pinheiro et al, 2016). The dynamics of the coevolutionary scenario of putatively highly host-specific symbionts, such as feather mites, could be analogous to that of a geographic mosaic of coevolution found in other systems in which populations are more connected (i.e., as the gene flow between symbiont populations inhabiting different hosts may be higher than previously thought), providing new avenues of research.…”

“…The IHS predicts that modularity in interaction networks mirrors discontinuities in dissimilarities between species (Pinheiro et al 2016). Clusters are, thus, imposed on the model and drive link formation, which produces modules in the network.…”

“…Under the resource breadth hypothesis (Krasnov et al, 2005), however, species with a broad host range would be generally better at exploiting all host species and have higher prevalence. Predictions from both hypotheses might be integrated when taking into account the structure of differences between hosts (Pinheiro et al, 2016). We emphasize that we did not test host range of rodent Eimeria in the present work but used the assumption of biologically meaningful taxonomy and traditional "morphospecies" within house mice.…”
