The prevalence and intensity of trematode larvae (metacercariae of Gymnophallus, Himasthla and Renicola) in blue mussels Mytilus edulis were studied at 19 intertidal sites distributed from the North Atlantic waters (Ireland, Iceland, Norway) to the Arctic Ocean (northwestern Russia). We explored the impact of different predictors (environmental and biological) including mussel age, density and maximal surface seawater temperature (SSTmax), in addition to bird (the final hosts for the studied trematodes) abundance, on the distribution of trematode larvae. The results indicated that the local abundance of the final hosts (gulls, waders and eider ducks) was a key factor determining trematode prevalence and intensity in second intermediate hosts (mussels). The infection by the metacercariae increased with the mussel age in all localities. The infection parameters of mussels were strongly dependent on both the density of the mussels and of the bird abundance. This dependence varied between the different parasitic
