Phenotypic Variability Induced by Parasites: Extent and Evolutionary Implications

Archive ouverte

Poulin, Robert | Thomas, Frédéric

Edité par CCSD ; Elsevier -

International audience. The diversity of ways in which parasites can modify the host genotypic signal has been documented in recent years. For example, parasites can shift the mean value and increase the variance of phenotypic traits in host populations, or alter the phenotypic sex ratio of host populations, with several evolutionary implications. Here, Robert Poulin and Frederic Thomas review the types of host traits that are modified by parasites, then explore some of the evolutionary consequences of parasite-induced alterations in host phenotypes and suggest some avenues for future research.
