Corticosterone selectively decreases humoral immunity in female eiders during incubation.
International audience Immunity is hypothesized to share limited resources with other physiological functions and this may partly account for the fitness costs of reproduction. Previous studies have shown that the acquired immunity of female common eider ducks (Somateria mollissima) is suppressed du...
