Albinism and phenotype of barn swallows (Hirundo rustica) from Chernobyl.
The effects of mutation on phenotypic expression are supposed to be mainly deleterious because mutations disrupt the expression of genes that function relatively well under current environmental conditions. Thus, mutations are assumed to give rise to deviant phenotypes that are generally selected against. Radioactive contamination in the Chernobyl region of Ukraine is associated with a signific...
متن کاملExperimental tail shortening in Barn Swallows ( Hirundo rustica ) affects haematocrit
1. Recent studies in Scotland suggest that the outermost tail feathers of Barn Swallows ( Hirundo rustica Linnaeus) may be around 10–12 mm longer than the aerodynamic optimum, with sexual selection for long tails accounting for this extra length. 2. To test this hypothesis, we shortened the outermost tail feathers in male and female Barn Swallows in southern Spain by cutting 1, 11 or 21 mm from...
متن کاملPrevalence and molecular characterization of Clostridium difficile isolated from European Barn Swallows (Hirundo rustica) during migration
BACKGROUND Clostridium difficile is an important bacterial pathogen of humans and a variety of animal species. Birds, especially migratory passerine species, can play a role in the spread of many pathogens, including Clostridium difficile. Barn Swallows (Hirundo rustica) nest in close proximity to human habitats and their biology is closely associated with cattle farming. Therefore, we hypothes...
متن کاملImmune System Responses to Ectoparasite Infections in Nestling Barn Swallows Hirundo rustica: an Experimental Approach
In altricial [helpless] birds, ectoparasite [external parasite] exposure during development may elicit a costly immune response requiring nestlings to redistribute energy away from growth and development and towards parasite defense. That altricial nestlings are born with an immature immune system may have implications for the mechanisms they use for immune defense. I studied how nestlings defe...
متن کاملAuk, The: Effects of feather lice on flight behavior of male Barn Swallows (Hirundo rustica)
ABSTRACT.-Parasites may affect host behavior in a number of ways, including their locomotory performance. We investigated whether the number of holes produced by the feather louse (Myrsidea rustica) affected flight behavior in adult male Barn Swallows (Hirundo rustica) by video-taping flight performance of individuals during escape and level flight. Percentage of time spent flapping during fora...
