Decomposing parasite fitness in a two-host, two-parasite system reveals the underpinnings of parasite specialization

AO_SCPLOWBSTRACTC_SCPLOWThe ecological specialization of parasites - whether they can obtain high fitness on very few or very many different host species - is a determining feature of their ecology. In order to properly assess specialization, it is imperative to measure parasite fitness across host species; to understand its origins, fitness... Show more
