    • Evolutionary Novelty in a Butterfly Wing Pattern through Enhancer Shuffling 

      Wallbank, Richard W. R.; Baxter, Simon W.; Pardo-Díaz, Carolina; Hanly, Joseph J.; Martin, Simon H.; Mallet, James; Dasmahapatra, Kanchon K. et al. (PLoS, 2016-01-15)
      An important goal in evolutionary biology is to understand the genetic changes underlying novel morphological structures. We investigated the origins of a complex wing pattern found among Amazonian Heliconius butterflies. ...
    • The gene cortex controls mimicry and crypsis in butterflies and moths 

      Nadeau, Nicola J.; Pardo-Diaz, Carolina; Whibley, Annabel; Supple, Megan; Saenko, Suzanne V.; Wallbank, Richard W. R.; Wu, Grace C. et al. (Nature Publishing Group, 2016-06-01)
      The wing patterns of butterflies and moths (Lepidoptera) are diverse and striking examples of evolutionary diversification by natural selection1, 2. Lepidopteran wing colour patterns are a key innovation, consisting of ...
    • Gene flow and the genealogical history of Heliconius heurippa 

      Salazar, Camilo; Jiggins, Chris D; Taylor, Jesse E; Kronforst, Marcus R; Linares, Mauricio (2008-05-02)
      Abstract Background The neotropical butterfly Heliconius heurippa has a hybrid colour pattern, which also contributes to reproductive isolation, making it a likely example of hybrid speciation. Here we used phylogenetic ...
    • Genetic diversity of Phytophthora infestans in the Northern-Andean region 

      Cardenas, Martha; Grajales, Alejandro; Sierra, Roberto; Rojas, Alejandro; Gonzalez-Almario, Adriana; Vargas, Angela; Marin, Mauricio et al. (2011-02-09)
      Abstract Background Phytophthora infestans (Mont.) de Bary, the causal agent of potato late blight, is responsible for tremendous crop losses worldwide. Countries in the northern part of the Andes dedicate a large proportion ...
    • An introgressed wing pattern acts as a mating cue 

      Sánchez, Angela P.; Pardo-Diaz, Carolina; Enciso-Romero, Juan; Muñoz, Astrid; Jiggins, Chris D.; Salazar, Camilo; Linares, Mauricio (Wiley, 2015-05-27)
      Heliconius butterflies provide good examples of both homoploid hybrid speciation and ecological speciation. In particular, examples of adaptive introgression have been detected among the subspecies of Heliconius timareta, ...
    • Towards the identification of the loci of adaptive 2 evolution 

      Pardo-Diaz, Carolina; Salazar, Camilo; Jiggins, Chris D. (Wiley, 2015-02-12)
      Summary: 1: Establishing the genetic and molecular basis underlying adaptive traits is one of the major goals of evolutionary geneticists in order to understand the connection between genotype and phenotype and elucidate ...
