Experimental test of a trade-off between moult and immune response in house sparrows Passer domesticus.
A trade-off between immune system and moulting is predicted in birds, given that both functions compete for resources. However, it is unclear whether such a trade-off exists during post-breeding moult. This study tests such a trade-off in the house sparrow (Passer domesticus). Males injected with an antigen (lipopolysaccharide) significantly moulted slower than sham-injected males. Moreover, ma...
متن کاملHumoral immunity to West Nile virus is long-lasting and protective in the house sparrow (Passer domesticus).
The house sparrow (Passer domesticus) is a common and abundant amplifying host of West Nile virus (WNV) and many survive infection and develop humoral immunity. We experimentally inoculated house sparrows with WNV and monitored duration and protection of resulting antibodies. Neutralizing antibody titers remained relatively constant for >or= 36 months (N = 42) and provided sterilizing immunity ...
متن کاملTwo new quill mite species of the family Syringophilidae (Acari: Prostigmata) parasitising the house sparrow Passer domesticus (L.) (Aves: Passeriformes).
Two new quill mite species of the family Syringophilidae, Picobia passeri sp. nov. and Krantziaulonastus dubinini sp. nov., are described from quills of the body feathers of the house sparrow Passer domesticus (L.) (Passeriformes: Passeridae) from the European part of Russia.
متن کاملUropygial gland size correlates with feather holes, body condition and wingbar size in the house sparrow Passer domesticus
The uropygial gland is an organ exclusive of birds that secretes an oily substance, the uropygial secretion, the functions of which are still debated. One of the proposed hypothesis is its possible action against chewing lice (order Phthiraptera), a group of avian ectoparasites that feed on feathers, causing different types of harm. However, this hypothesis lacks support. The present study anal...
متن کاملGrowth and development of house sparrows (Passer domesticus) in response to chronic food restriction throughout the nestling period.
Birds have evolved phenotypic plasticity in growth and developmental patterns in order to respond to fluctuating environmental conditions and to mitigate the impact of poor feeding on fitness. Chronic food shortage can occur during chick development in the wild, and the responses of altricial birds have not been thoroughly studied. House sparrow (Passer domesticus) nestlings were raised in the ...
