- Title
Sexual dimorphism and tail-length in widowbirds and bishopbirds (Ploeeidae: Euplectes spp.): a reassessment.
- Authors
CRAIG, ADRIAN J. F. K.; VILLET, MARTIN H.
- Abstract
No evidence for sexual selection in the evolution of tail-length or wing-length in widow birds and bishopbirds (genus Euplectes) was found when the methods used by previous authors were applied to a larger set of data. Nuptial tail-length dimorphism scaled with body size dimorphism except in Euplectes progne, and interpopulation variation in taillength could be explained by genetic drift alone. Wing-length appears to be under stabilizing selection and scales allometrically with body size, with no relation to tail-length unless E. progne is included in the analysis.
