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. ...

Gene flow and Andean uplift shape the diversification of Gasteracantha cancriformis (Araneae: Araneidae) in Northern South America

Salgado-Roa, Fabian C.; Pardo-Diaz, Carolina; Lasso, Eloisa; Arias, Carlos F.; Solferini, Vera Solferini; Salazar, Camilo

The Andean uplift has played a major role in shaping the current Neotropical biodiversity. However, in arthropods other than butterflies, little is known about how this geographic barrier has impacted species historical ...

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. ...

Genomic architecture of adaptive color pattern divergence and convergence in Heliconius butterflies

Supple, Megan A.; Hines, Heather M.; Dasmahapatra, Kanchon K.; Lewis, James J.; Nielsen, Dahlia M.; Lavoie, Christine; Ray, David A.; Salazar, Camilo; Owen McMillan, W.; Counterman, Brian

Identifying the genetic changes driving adaptive variation in natural populations is key to understanding the origins of biodiversity. The mosaic of mimetic wing patterns in Heliconius butterflies makes an excellent system ...

Hybridization promotes color polymorphism in the aposematic harlequin poison frog, Oophaga histrionica

Medina, Iliana; Wang, Ian J.; Salazar, Camilo; Amezquita, Adolfo

Whether hybridization can be a mechanism that drives phenotypic diversity is a widely debated topic in evolutionary biology. In poison frogs (Dendrobatidae), assortative mating has been invoked to explain how new color ...

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 ...

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 ...
