The evolution of parasite virulence and the origin of cooperative genomes in primitive cells
are both problems that balance cooperative and competitive interactions among symbionts. I …

Most species of insects are infected with heritable, facultative symbionts. Such symbionts
first appear within a host lineage as a result of lateral transfer from other host species …

Parasite—host coevolution can have many different endpoints, not simply the
commensalism of 'conventional wisdom'. Empirical studies and mathematical models are …

Probably a very small biochemical change will give a host species a substantial degree of
resistance to a highly adapted microorganism. This has an important evolutionary effect. It …

The interaction between multiple parasite strains within different host types may influence
the evolutionary trajectories of parasites. In this article, we formulate a deterministic model …

In this paper we wish to develop three themes, each having to do with evolutionary aspects
of associations between hosts and parasites (with parasite defined broadly, to include …

A coevolutionary model is developed of the interaction between a host and an internal
parasitoid, where the outcome of parasitism depends upon the extent to which individual …

Understanding the coevolution of hosts and parasites is a long‐standing goal of
evolutionary biology. There is a well‐developed theoretical framework to describe the …

Hosts are often infected by a variety of different parasites, leading to competition for hosts
and coevolution between parasite species. There is increasing evidence that some vertically …

Analyses of the selection pressures acting on parasite virulence are made more complicated
when individual hosts can simultaneously harbour many different strains or genotypes of a …
