Parasites as prey: the effect of cercarial density and alternative prey on consumption of cercariae by four non-host species
In parasites with complex life cycles the transmission of free-living infective stages can be influenced by ambient community diversity, in particular via predation. Here, we experimentally investigated whether parasite density and the presence of alternative prey can alter predation rates on free-l...
