“…Fourthly, we have tentatively extended some of the points from our discussion to provide a wider consideration of helminth evolution. We have found the approaches of Llewellyn (1965) and Inglis ( 1 9 7 1 ) to parasite evolution to be most stimulating and, although we accept Cameron's (1964) admonition that the story has to be told on broad general lines, sufficient information and interest has emerged recently (Willmott, 1981) to suggest that a more detailed account may soon be prepared.…”

“…Host–parasite associations may reflect a long history of co‐evolution, during which the ecology of the parasite is strongly linked with that of the host (Cameron 1964; Brooks & McLennan 1993; Poulin 1995). For these associations the effects of history and the effects of ecology are difficult to separate (Manter 1966; Holmes & Price 1980; Brooks & McLennan 1993; Winston 1995).…”

1. This article compares generalist (parasite species found on two or more host species) and specialist (found on only one host species) monogenean parasite species of fish. The reduction of the host range – that is an increase in host specificity – may correspond with a better adaptation of the parasite to a more predictable host environment. A more predictable environment may allow the parasite species to develop specific adaptations. 2. We assume that the more predictable host environment can be evaluated by host body size, since numerous life‐traits, such as longevity, are positively correlated with size. 3. We found that specialist parasites parasitize larger hosts species than generalist parasites. We also found a good relationship between host body size and parasite body size for specialist parasite species. 4. An adaptation to the mechanical problems encountered in the host's gill chamber may lead to an increase in parasite body size. The infection of a larger part of the host population in order to decrease the chances of local extinction due to fluctuations of host abundance may be another adaptive mechanism. 5. We found a negative correlation between parasite body size and prevalence for generalist parasite species. This relationship disappeared when using the comparative method controlling for phylogeny, which proved that it was a phylogenetic effect.

“…With advancing levels of parasitism, the dependence of the nematode on its host increased and its further evolution was more decisively infl uenced by the evolution of the host. The topic of coevolution of nema todes and their animal hosts has been discussed extensively (9,25), but very little is known about coevolution in plant-parasitic nematodes (29).…”
