    Parasitism can represent a potent agent of selection, and introduced parasites have the potential to substantially alter their new hosts' ecology and evolution. While significant impacts have been reported for parasites that switch to new host species, the effects of macroparasite introduction into naïve populations of host species with which they have evolved remain poorly understood. Here, we investigate how the estuarine white‐fingered mud crab (Rhithropanopeus harrisii ) has adapted to parasitism by an introduced rhizocephalan parasite (Loxothylacus panopaei ) that castrates its host. While the host crab is native to much of the East and Gulf Coasts of North America, its parasite is native only to the southern end of this range. Fifty years ago, the parasite invaded the mid‐Atlantic, gradually expanding through previously naïve host populations. Thus, different populations of the same host species have experienced different degrees of historical interaction (and thus potential evolutionary response time) with the parasite: long term, short term, and naïve. In nine estuaries across this range, we examined whether and how parasite prevalence and host susceptibility to parasitism differs depending on the length of the host's history with the parasite. In field surveys, we found that the parasite was significantly more prevalent in its introduced range (i.e., short‐term interaction) than in its native range (long‐term interaction), a result that was also supported by a meta‐analysis of prevalence data covering the 50 years since its introduction. In controlled laboratory experiments, host susceptibility to parasitism was significantly higher in naïve hosts than in hosts from the parasite's native range, suggesting that host resistance to parasitism is under selection. These results suggest that differences in host–parasite historical interaction can alter the consequences of parasite introductions in host populations. As anthropogenically driven range shifts continue, disruptions of host–parasite evolutionary relationships may become an increasingly important driver of ecological and evolutionary change.

    Community composition (relative abundance) separated by native and cryptogenic, and introduced species of each community from coastal sites across a geographic gradient spanning the sub-arctic to the tropics from 2015-2017
    (Biological and Chemical Oceanography Data Management Office (BCO-DMO). Contact: bco-dmo-data@whoi.edu, 2021-08-30) Freestone, Amy ; Torchin, Mark ; Lopez, Diana P. ; Bonfim, Mariana ; Jurgens, Laura ; Repetto, Michele F. ; Schloder, Carmen ; Ruiz, Gregory
    Community composition of sessile marine invertebrates from coastal sites across a geographic gradient spanning the sub-arctic to the tropics. Community composition is divided into two data sets. One corresponds to the community composition of the introduced species found in each community, and the other data set corresponds to the community composition of native and cryptogenic species found in each community.
