Different modes of evolution in males and females generate dichromatism in fairy-wrens (Maluridae)
Sexual dichromatism in birds is often attributed to selection for elaboration in males. However, evolutionary changes in either sex can result in plumage differences between them, and such changes can result in either gains or losses of dimorphism. We reconstructed the evolution of plumage colors in both males and females of species in Maluridae, a family comprising the fairy-wrens (Malurus, Cl...
متن کاملConcordant evolution of plumage colour, feather microstructure and a melanocortin receptor gene between mainland and island populations of a fairy-wren.
Studies of the patterns of diversification of birds on islands have contributed a great deal to the development of evolutionary theory. In white-winged fairy-wrens, Malurus leucopterus, mainland males develop a striking blue nuptial plumage whereas those on nearby islands develop black nuptial plumage. We explore the proximate basis for this divergence by combining microstructural feather analy...
متن کاملIncreased conspicuousness can explain the match between visual sensitivities and blue plumage colours in fairy-wrens.
Colour signals are expected to match visual sensitivities of intended receivers. In birds, evolutionary shifts from violet-sensitive (V-type) to ultraviolet-sensitive (U-type) vision have been linked to increased prevalence of colours rich in shortwave reflectance (ultraviolet/blue), presumably due to better perception of such colours by U-type vision. Here we provide the first test of this wid...
متن کاملEvolutionary Relationships among Blue-and Black-plumaged Populations of the White-winged Fairy-wren (malurus Leucopterus)
The white-winged fairy-wren (Malurus leucopterus) exhibits striking plumage colour variation between the Australian mainland and two islands (Dirk Hartog Island and Barrow Island) off the coast of Western Australia. Adult males on the mainland are bright blue with white wings and adult males on the two islands are black with white wings. To examine evolutionary relationships within this species...
متن کاملMultiple shifts between violet and ultraviolet vision in a family of passerine birds with associated changes in plumage coloration.
Colour vision in diurnal birds falls into two discrete classes, signified by the spectral sensitivity of the violet- (VS) or ultraviolet-sensitive (UVS) short wavelength-sensitive type 1 (SWS1) single cone. Shifts between sensitivity classes are rare; three or four are believed to have happened in the course of avian evolution, one forming UVS higher passerines. Such shifts probably affect the ...
