| introduced bullfrogs and their parasites: haematoloechus longiplexus (trematoda) exploits diverse damselfly intermediate hosts on vancouver island. | the lung fluke, haematoloechus longiplexus, is the most prevalent and abundant parasite of introduced bullfrogs on vancouver island, british columbia, canada. the ecological success of this trematode in invasive bullfrogs is related to the fluke's ability to utilize native intermediate hosts for transmission. the purpose of this study was to identify the odonate (dragonfly/damselfly) species involved in the transmission of h. longiplexus to the introduced bullfrog. the prevalences and mean inten ... | 2013 | 22924931 |
| do invasive bullfrogs in victoria, british columbia, canada, show evidence of parasite release? | few studies have examined vertebrate models of invasive species to explore parasite release as a proposed mechanism through which host species might become invasive. in this study, we examined evidence for parasite release in invasive american bullfrogs (rana catesbeiana/lithobates catesbeianus) from five sites in victoria, british columbia, canada. we examined helminth species richness, as well as the prevalence, intensity and abundance of lung and kidney fluke infections. these flukes are expe ... | 2013 | 22716948 |
