摘要: The impact of parasitism on host populations will be modulated by both genetic variation for susceptibility, and phenotypically plastic life-history traits that are altered to lessen the fitness consequences infection. In this study we tested shifts in crustacean Daphnia magna following exposure horizontally transmitted microsporidian, Glugoides intestinalis. two separate experiments, exposed hosts parasite spores measured their fecundity relative controls. We show G. intestinalis compensation, i.e. shift strategy towards early reproduction. Our experiments included multiple genotypes, subtle differences among them indicated compensation could subject parasite-mediated natural selection.
