Gyrodactylus proterorhini in its non-native range: distribution and ability to host-switch in freshwaters
Successful co-introduction of a parasite and its host relies not only on presence of the parasite on host individuals in the founder population but also on the ability of both host and parasite to persist in t...

Open AccessNon-native gobies facilitate the transmission of Bucephalus polymorphus (Trematoda)
Introduced species can modify local host-parasite dynamics by amplifying parasite infection which can ‘spill-back’ to the native fauna, whether they are competent hosts for local parasites, or by acting as par...

Temporal effects on host-parasite associations in four naturalized goby species living in sympatry
Introduced host species are often characterised by reduced parasite numbers compared to their native populations. Any such advantage gained from parasite release following introduction into a new area may ofte...

Effect of habitat conditions on parasite infection in 0+ juvenile perch (Perca fluviatilis L.) in two Czech reservoirs
The objective of this study was to identify potential effects of habitat conditions on parasite infection risk in reservoirs. For this, we compared parasite infection in 0+ perch (Perca fluviatilis L.) between re...

Open AccessDoes invasive Chondrostoma nasus shift the parasite community structure of endemic Parachondrostoma toxostoma in sympatric zones?
The composition of parasite communities in two cyprinid species in southern France – native and threatened Parachondrostoma toxostoma and introduced Chondrostoma nasus – was investigated. In sympatry, these two s...
