Ecological Correlates and Phylogenetic Signal of Host Use in North American Unionid Mussels

We investigated the relationships among species of North American unionid mussels and their known host fishes from a macroevolutionary perspective to test whether and how ecological and evolutionary factors correlate with patterns of host use. A subset of 69 mussel species were chosen based on data availability regarding their fish host repertoires, phylogenetic relationships, and ecology. The data uploaded here encompasses all the host-parasite interactions, ecological data, and R code used to perform analyses.
