dc.abstract.enInvasive freshwater bivalves harm native species, ecosystems and biodiversity, and incur economic costs. The enemy release hypothesis posits that invasive species are released from enemies during the invasion process, giving them a competitive advantage in the new environment. We compared parasitism in two invasive freshwater bivalves, Sinanodonta woodiana and Corbicula fluminea between their original range (China) and invaded range (Europe). For S. woodiana, the average sample-size-standardized population-specific parasite taxon richness was 2.1 times as high, and sum of prevalence was 3.0 times as high in the native range (3 populations, 81 individuals studied) as in the invaded range (6 populations, 210 individuals studied). For C. fluminea, the average standardized population-specific parasite taxon richness was 1.3 and sum of prevalences was 27.5 in the native range (4 populations, 749 individuals studied), whereas all European C. fluminea were free of parasites (7 populations, 418 individuals studied). The results demonstrate loss of parasites as a result of invasion. Previous studies have shown that parasite pressure on S. woodiana and C. fluminea in the invaded range in Europe is, on average, lower than on sympatric native freshwater mussel populations. Together, these results support one aspect of the enemy release hypothesis: invasive bivalves experience reduced parasite loads as a result of invasion, which may contribute to their success, given the costs typically imposed by parasitism.
