TL;DR: Overall, the findings indicate that most (if not all) metazoan ectoparasite communities of marine fish live in non-saturated, little-ordered assemblages and that competitive interactions are probably scarce.

TL;DR: It is suggested that the parasite should be able to track common snail genotypes within populations and, therefore, that it could be at least partially responsible for the persistence of sexual subpopulations of the snail in those populations that have both obligately sexual and obligately parthenogenetic females.
Abstract: In each of two reciprocal cross-infection experiments, a digenetic trematode (Microphallus sp.) was found to be significantly more infective to snails (Potamopyrgus antipodarum) from its local host populations. This gives strong evidence for local adaptation by the parasite and indicates that there is a genetic basis to the host-parasite interaction. It is suggested that the parasite should be able to track common snail genotypes within populations and, therefore, that it could be at least partially responsible for the persistence of sexual subpopulations of the snail in those populations that have both obligately sexual and obligately parthenogenetic females.

TL;DR: It is predicted that gigantism will occur commonly in short-lived or semelparous species of snails but rarely, if ever, in long-lived iteroparous species which are predominately marine.

TL;DR: Investigation within 15 genera of metazoan parasites found in Canadian freshwater fish suggests that the availability of suitable host species may have been a key factor limiting the colonization of new hosts by fish parasites.
