“…As filtration rates increase with body size, larger cockle hosts will be exposed to larger numbers of infective stages and most likely have higher infection levels. While there is some evidence for a positive relationship between cockle size (or age) and metacercarial infection levels in the literature (de Montaudouin et al ., 1998; Jensen et al ., 1999; Thieltges, 2008; but see de Montaudouin et al , 2012), cercarial removal only lead to very low infections of cockles in our experiment, with a mean intensity of 1–2.7 metacercariae and no relationship with cockle size. This suggests that the uptake of cercariae by cockles does not necessarily lead to infections but that a large number of cercariae may rather be lost in the course of the filtration, possibly by immobilizing cercariae on the cockles’ gills and subsequent digestion.…”

Consumer and host body size effects on the removal of trematode cercariae by ambient communities

Parasite transmission can be altered via the removal of parasites by the ambient communities in which parasite–host interactions take place. However, the mechanisms driving parasite removal remain poorly understood. Using marine trematode cercariae as a model system, we investigated the effects of consumer and host body size on parasite removal rates. Laboratory experiments revealed that consumer or host body size significantly affected cercarial removal rates in crabs, oysters and cockles but not in shrimps. In general, cercarial removal rates increased with consumer (crabs and oysters) and host (cockles) body size. For the filter feeding oysters and cockles, the effects probably relate to their feeding activity which is known to correlate with bivalve size. Low infection levels found in cockle hosts suggest that parasite removal by hosts also leads to significant mortality of infective stages. The size effects of crab and shrimp predators on cercarial removal rates were more complex and did not show an expected size match-mismatch between predators and their cercarial prey, suggesting that parasite removal rates in predators are species-specific. We conclude that to have a comprehensive understanding of parasite removal by ambient communities, more research into the various mechanisms of cercarial removal is required.

“…3,000 km) are stronger than temporal effects (8 years), once trematode composition at a given site is often stable at multiannual scale. As an illustration, de Montaudouin et al (2012) showed that trematode communities of Arcachon bay, France, were the same after years, the same temporal gap as in this study, due to environmental stability along time. In the same direction, in the Ria de Aveiro coastal lagoon, one of the sampled systems, diversity of trematode was equivalent after 6 years (Freitas et al, 2014;Russell-Pinto et al, 2006).…”

“…Studies involving bivalve second intermediate hosts are scarcer (e.g. Goater 1993;de Montaudouin et al 1998de Montaudouin et al , 2012de Montaudouin and Lanceleur 2011;Desclaux et al 2004;Thieltges 2007;Thieltges and Reise 2007). In particular, blue mussels Mytilus edulis have received little attention Thieltges 2006;Prinz et al 2011;Wilson et al 2013).…”

abundance of avian final hosts) on trematode infection was examined. Infection levels correlated with the interaction between local bird abundance and mussel age and density. They increased with mussel age but their dependence on mussel density and bird abundance varied among parasite genera. Prevalence and intensity increased with SSTmax for Renicola spp., but no relationship was found for Gymnophallus and Himasthla spp. The ambiguous effect of SSTmax is likely explained by the broad range of optimal temperatures for the normal functioning of trematode larvae (cercariae) infective for mussels and by the high dependence of the level of mussel infection on a combination of local ecological factors. High infection levels were observed even in localities with a low SSTmax. No mussels were infected in the most northeastern population, probably due to extreme conditions in the Arctic intertidal preventing trematode transmission. Abstract Blue mussels, Mytilus edulis, serve as second intermediate hosts for several trematode species, but little is known about the mechanisms underlying parasite infections in mussels. To reveal these mechanisms, the prevalence and intensity of trematode larvae (metacercariae in species of Gymnophallus, Himasthla and Renicola) were examined in blue mussels at 19 intertidal sites from the North Atlantic (Ireland, Iceland, Norway) to the Arctic Ocean (north-western Russia). Mussel samples were taken in [2005][2006][2007][2008]. The impact of a number of environmental (maximal sea surface temperature, SSTmax) and biological factors (mussel age and density and the Communicated by J. Grassle.
