Summary

Populations of Fasciola hepatica infecting sheep are regulated by at least 3 density-dependent processes. Parasite deaths due to parasite-induced primary host mortality, fluke fecundity and asexual multiplication in the intermediate snail host, Lymnaea truncatula, vary according to the intensity of infection. Empirical and theoretical evidence is used to assess the extent to which each of these processes in turn affects parasite population numbers.
