SUMMARY:Magic traits\, sensory drive and local adaptation: modelling the e
 cological context of divergent sexual selection - Sander van Doorn - Unive

DESCRIPTION:Modern speciation research has developed a renewed appreciatio
 n for the role of natural and sexual selection in population divergence. T
 heoretical studies have contributed to this change by illustrating that di
 vergent sexual selection can cause the rapid evolution of reproductive iso
 lation\, and by clarifying how ecological interactions can generate a pers
 istent regime of disruptive selection that is capable of supporting adapti
 ve diversification. Yet\, these important insights are rooted in independe
 nt research traditions that have hardly been integrated. In this talk\, I 
 will explore the interface of ecological and sexual selection models based
  on currently debated topics that each highlight an intimate connection be
 tween ecology and sexual selection: magic traits\, sensory drive and mate 
 choice based on cues that signal local adaptation. I will argue that ecolo
 gical and sexual selection models complement each other's weaknesses and t
 hat some fundamental obstacles to speciation with gene flow disappear when
  the ecological context of sexual selection is taken into account.
