Thus, diversity is associated with different nodal properties in larval and adult parasites, and association strengths also differ, strongly reflecting the life cycles of parasites and the food chains they follow to complete transmission.Īnderson TK, Sukhdeo MV (2011) Host centrality in food web networks determines parasite diversity. There was a notable lack of association with the diversity of any parasite guild and fish length, trophic level, or trophic category. The proportion of parasite species present as larvae in a host species was correlated with the diversity of its predators. Prey diversity was more strongly associated with the diversity of adult parasites than with that of larvae. Larval parasite diversity increased with the diversity of both prey and predators, but increases in predator diversity had a greater effect. Fish that consumed more species of prey had more diverse trophically transmitted adult parasites. Local predator–prey relationships were determined from stomach contents, parasites, and published data in 8,229 fish in 31 species and in seals and piscivorous birds. We searched for factors that best predict the diversity of larval and adult endoparasites in 4105 fish in 25 species studied over a three-year period in the Bothnian Bay, Finland. However, no study has attempted to distinguish among all four correlates, which may have differential importance for trophically transmitted parasites occurring as larvae or adults.
Various aspects of parasite diversity have been observed to be correlated with the trophic level, size, diet breadth, and vulnerability to predation of hosts. It does not store any personal data.Recent studies of aquatic food webs show that parasite diversity is concentrated in nodes that likely favour transmission.
