Contrasting associations between breeding coloration and parasitism of male Arctic charr relate to parasite species and life cycle stage
Conspicuous carotenoid ornamentation is considered a signal of individual “quality” and one of the most intensely studied traits found to co-vary with parasitism. Since it has been suggested that only “high quality” individuals have enough resources to express excessive sexual ornaments and resist p...
