    "abstract": "Immunity is hypothesized to share limited resources with other physiological\nfunctions and this may partly account for the fitness costs of reproduction.\nPrevious studies have shown that the acquired immunity of female common eider\nducks (Somateria mollissima) is suppressed during their incubation, during\nwhich they entirely fast. Corticosterone was proposed to be an underlying\nphysiological mechanism for such immunosuppression. Therefore, the current\nstudy aimed to assess the effects of exogenous corticosterone on acquired\nimmunity in captive eiders. To this end, females were implanted with\ncorticosterone pellets at different stages of their incubation fast. We\nmeasured total immunoglobulin levels, T-cell-mediated immune response, body\nmass and corticosterone levels in these females and compared them with those of\ncontrol females prior to and after manipulation (i.e. corticosterone pellet\nimplantation). To mimic corticosterone effects on body mass, we experimentally\nextended fasting duration in a group of females termed ;late fasters\u0027...",
