    • A hybrid zone provides evidence for incipient ecological speciation in Heliconius butterflies 

      Arias, Carlos F.; Muñoz, Astrid G.; Jiggins, Chris D; Mavárez, Jesús; Bermingham, Eldredge; Linares, Mauricio
      In Heliconius butterflies, it has been proposed that speciation occurs through a combination of divergence in ecological habitat preferences and mimetic colour patterns. Here we test this hypothesis by investigating a ...

      Merchán, H. Alejandro; Jiggins, Chris D; Linares, Mauricio
      In the western cordillera of the Cauca valley, Colombia, there is a narrow hybrid zone between two races of Heliconius cydno , one of which is polymorphic. Three large broods show that most of the phenotypic variation ...
