Mate choice for genetic quality when environments vary: suggestions for empirical progress
Mate choice for good-genes remains one of the most controversial evolutionary processes ever proposed. This is partly because strong directional choice should theoretically deplete the genetic variation that e...

Multivariate selection shapes environment-dependent variation in the clonal morphology of a red seaweed
Within-individual strategies of variation (e.g., phenotypic plasticity) are particularly relevant to modular organisms, in which ramets of the same genetic individual may encounter diverse environments imposin...

Open AccessSexual responsiveness is condition-dependent in female guppies, but preference functions are not
Variation in mate choice behaviour among females within a population may influence the strength and form of sexual selection, yet the basis for any such variation is still poorly understood. Condition-dependen...

Open AccessDirect selection on male attractiveness and female preference fails to produce a response
Theoretical studies suggest that direct and indirect selection have the potential to cause substantial evolutionary change in female mate choice. Similarly, sexual selection is considered a strong force in the...

Variation in Female Mate Choice within Guppy Populations: Population Divergence, Multiple Ornaments and the Maintenance of Polymorphism
The evolutionary significance of variation in mate choice behaviour is currently a subject of some debate and considerable empirical study. Here, I review recent work on variation within and among guppy (Poecilia...

Copying and the repeatability of mate choice
Models of sexual selection by female choice require heritable variation in female mating preferences in order for sexual selection to operate. However, recent theoretical work shows that female preferences wh...
