对引进的片足类甲壳动物钩虾Gammarus pulex和钩虾G.虎斑拟步行者正在取代本地的G.在北方爱尔兰的一些淡水地点发现了杜贝尼凯尔特人。我们调查了寄生虫和附着生物感染的人口在拉根河和内湖，本地和入侵物种发生。四种寄生虫和附着生物的流行率在本地G。d，celticus比在入侵端足类动物在两个领域的网站。在内格湖，G. D.与入侵物种相比，celticus个体遭受了更高的轮虫Embata parasitica和原生动物Epistylis的负担。这些模式可能反映了寄生虫的宿主特异性，也可能是由于本地和入侵宿主物种的不同亲和性造成的。我们认为寄生对宿主入侵和物种分布的影响。
The introduced amphipod crustaceans Gammarus pulex and G. tigrinus are displacing the native G. duebeni celticus in a number of freshwater sites in Northern Ireland. We investigated parasite and epibiont infection in populations in the River Lagan and Lough Neagh where both native and invading species occur. Prevalence of the four parasites and epibionts observed was higher in the native G. d, celticus than in the invading amphipods at both field sites. In Lough Neagh, G. d. celticus individuals suffered higher burdens of the rotifer Embata parasitica and the protozoan Epistylis in comparison with the invading species. These patterns may reflect host specificity by the parasites or may result from different susceptibilities of the native and invading host species. We consider the influence of parasitism on host invasions and resulting species distributions.
