Journal ArticleDOI
Sexual selection on song and cuticular hydrocarbons in two distinct populations of Drosophila montana.
TL;DR: The nature and targets of sexual selection on song, CHCs, and both traits combined within the populations of Drosophila montana were characterized and a character previously shown to be important for species recognition, interpulse interval, was found to be under sexual selection.
Journal ArticleDOI
Environmental correlates of inversion frequencies in natural populations of seaweed flies (Coelopa frigida)
Roger K. Butlin,T H Day +1 more
TL;DR: Karyotype frequencies cycled seasonally and were associated with both temperature and the incidence of gales and the interactions of ecological and life-historical factors with the observed genetical variation are discussed.
Journal ArticleDOI
How sympatric is speciation in the Howea palms of Lord Howe Island
Wiesław Babik,Roger K. Butlin,William J. Baker,Alexander S. T. Papadopulos,Matthieu Boulesteix,Marie-Charlotte Anstett,Christian Lexer,Christian Lexer,Ian Hutton,Vincent Savolainen,Vincent Savolainen +10 more
TL;DR: It is found that Howea forsteriana is less abundant than Howea belmoreana, and speciation in Howea was indeed sympatric, although under certain strict definitions it may be called parapatric.
Journal ArticleDOI
Barriers to gene flow
TL;DR: The role of Chromosome Change in Species Evolution is illustrated in this chapter by Max King, who examines the role of chromosome change in the evolution of species selection.
Journal ArticleDOI
The extent of variation in male song, wing and genital characters among allopatric Drosophila montana populations.
TL;DR: The phenotypic divergence among populations did not coincide with the extent of their genetic divergence, suggesting that the characters are not evolving neutrally, and a history of directional and/or diversifying rather than balancing selection is suggested.
