    • Deep mitochondrial divergence within a Heliconius butterfly species is not explained by cryptic speciation or endosymbiotic bacteria 

      Muñoz, Astrid G; Baxter, Simon W; Linares, Mauricio; Jiggins, Chris D
      Background: Cryptic population structure can be an indicator of incipient speciation or historical processes. We investigated a previously documented deep break in the mitochondrial haplotypes of Heliconius erato chestertonii ...

    • Evolutionary novelty in a butterfly wing pattern through enhancer shuffling 

      Wallbank, Richard W. R.; Baxter, Simon W.; Pardo-Diaz, Carolina; Hanly, Joseph J.; Martin, Simon H.; Mallet, James; Dasmahapatra, Kanchon K.; Salazar, Camilo; Joron, Mathieu; Nadeau, Nicola; McMillan, W. Owen; Jiggins, Chris D.
      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. ...

    • Genome-wide evidence for speciation with gene flow in Heliconius butterflies 

      Martin, Simon H.; Dasmahapatra, Kanchon K.; Nadeau, Nicola J.; Salazar, Camilo; Walters, James R.; Simpson, Fraser; Blaxter, Mark; Manica, Andrea; Mallet, James; Jiggins, Chris D.
      Most speciation events probably occur gradually, without complete and immediate reproductive isolation, but the full extent of gene flow between diverging species has rarely been characterized on a genome-wide scale. ...

    • Male sex pheromone components in Heliconius butterflies released by the androconia affect female choice 

      Darragh, Kathy; Vanjari, Sohini; Mann, Florian; Gonzalez-Rojas, Maria F.; Morrison, Colin R.; Salazar, Camilo; Pardo-Diaz, Carolina; Merrill, Richard M.; McMillan, W. Owen; Schulz, Stefan; Jiggins, Chris D.
      Sex-specific pheromones are known to play an important role in butterfly courtship, and may influence both individual reproductive success and reproductive isolation between species. Extensive ecological, behavioural and ...

    • Patterns of Z chromosome divergence among Heliconius species highlight the importance of historical demography 

      Van Belleghem, Steven M.; Baquero, Margarita; Papa, Riccardo; Salazar, Camilo; McMillan, W. Owen; Counterman, Brian A.; Jiggins, Chris D.; Martin, Simon H.
      Sex chromosomes are disproportionately involved in reproductive isolation and adaptation. In support of such a “large-X” effect, genome scans between recently diverged populations and species pairs often identify distinct ...

    • Peace in Colombia is a critical moment for Neotropical connectivity and conservation : Save the northern Andes-Amazon biodiversity bridge 

      Clerici, Nicola; Salazar, Camilo; Pardo-Diaz, Carolina; Jiggins, Chris D.; Richardson, James-Edward; Linares, Mauricio
      Colombia is one of the most biodiverse countries in the world that has historically and is currently experiencing extensive deforestation and habitat fragmentation. Here we show how the most extensive region acting as a ...

    • Wing patterning gene redefines the mimetic history of Heliconius butterflies 

      Hines, Heather M.; Counterman, Brian A.; Papa, Riccardo; Albuquerque de Moura, Priscila; Cardoso, Marcio Z.; Linares, Mauricio; Mallet, James; Reed, Robert D.; Jiggins, Chris D.; Kronforst, Marcus R.; McMillan, W. Owen
      The mimetic butterflies Heliconius erato and Heliconius melpomene have undergone parallel radiations to form a near-identical patchwork of over 20 different wing-pattern races across the Neotropics. Previous molecular ...
