The preceding chapters of the book focused on interactions between hosts and parasites. This chapter focuses on competitive interactions between different species of parasites, and the role of the host in mediating those interactions. Parasites do not live in isolation, but are members of diverse parasite communities that share hosts. While no individual harbors all parasites known from that host species, most individuals support more than one species of parasite at a time. The presence of a given parasite species can have a negative effect on other parasites due to competition for limiting resources in or on the shared host. Even parasites that exploit very different parts of a host's body may compete, because each host individual is ultimately a single resource. Interspecific competition can lead to the coadaptation of traits that reduce the intensity of competition. Thus, in addition to coevolving with the host species, parasites coevolve with other parasites that share that same host species. The chapter begins by considering competition between parasite species, in general. It then provides a more detailed overview of competition between species of lice.
