Cím:	Diet quality affects postnuptial molting and feather quality of the house sparrow (Passer domesticus) : interaction with humoral immune function? / Péter László Pap, Csongor István Vágási, Gábor Árpád Czirják, Zoltán Barta

Megjegyzések:	We investigated the effects of nutritional limitation, humoral immune activation, and their interaction on postnuptial molting of aviary-kept house sparrows (Passer domesticus (L., 1758. In a 2*2 experimental design, we measured the progress of molting and the quality of feathers produced during molting by house sparrow exposed to different diet qualities (high and low9 and humoral immune activation with sheep red blood cells (SRBC). Food quality, but not the activation of humoral immunity, affected significantly the body mass and the process of molting.Sparrows feeding on low-quality food had decreased body mass and longer molts than the high-quality group.Low-quality food, but not the activation of humoral immunity, reduced significantly the length and mass (i.e.,the quality) of primaries grown during molting. birds responded significantly to injection with SRBC compared with the control group, but the immune response was similar between nutritional groups. The absence of a negative effect of humoral immunity on molting in house sparrows might be related to the low energy and nutritional requirements of mounting and maintaining a humoral immune response.
