Male-biased brood sex ratio depresses average phenotypic quality of barn swallow nestlings under experimentally harsh conditions.

Oecologia - 1 May 2008

Saino Nicola, de Ayala Rosa Mary, Martinelli Roberta, Boncoraglio Giuseppe

Abstract excerpt

Sex allocation strategies are believed to evolve in response to variation in fitness costs and benefits arising from the production of either sex and can be influenced by the differential susceptibility of sons and daughters to environmental conditions. We tested the effects of manipulating brood size and the sex ratio of the nestmates and the effect of sex on the phenotypic quality of individual barn swallow...
