A major gene controls mimicry and crypsis in butterflies and moths
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 ...

A molecular systematic analysis of the Neotropical banner winged damselflies (Polythoridae: Odonata)
The Neotropics are a hotspot of global diversity for many groups of organisms, including the dragonflies and damselflies (Insecta: Odonata). While the number of biodiversity surveys and new species descriptions for Neotropical ... Artículo. 2018

A neotropical polymorphic damselfly shows poor congruence between genetic and traditional morphological characters in Odonata
The Neotropical damselfly genus Polythore consists of nineteen described morphospecies. We used the COI barcode locus (799 bp), male genitalia, wing venation, and geometrical pattern variation to clarify specific status ...

A new subspecies in a Heliconius butterfly adaptive radiation (Lepidoptera: Nymphalidae)
A fundamental goal in evolutionary biology is to understand how evolutionary patterns and processes shape natural diversity. This, however, requires a complete characterization of the phenotypic and genetic variation between ... Artículo. 2017

Adaptive introgression across species boundaries in Heliconius butterflies
de la Universidad del Rosario. Artículo. 2012
-
An introgressed wing pattern acts as a mating cue
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, ... Artículo. 2015

An ultra-high vacuum scanning tunneling microscope operating at sub-Kelvin temperatures and high magnetic fields for spin-resolved measurements
We present the construction and performance of an ultra-low-temperature scanning tunneling microscope (STM), working in ultra-high vacuum (UHV) conditions and in high magnetic fields up to 9 T. The cryogenic environment ... Artículo. 2018

Assortative mating preferences among hybrids offers a route to hybrid speciation
Homoploid speciation generates species without a change in chromosome number via introgressive hybridization and has been considered rare in animals. Heliconius butterflies exhibit bright aposematic color patterns that ... Artículo. 2009
-
Butterfly genome reveals promiscuous exchange of mimicry adaptations among species
The evolutionary importance of hybridization and introgression has long been debated. Hybrids are usually rare and unfit, but even infrequent hybridization can aid adaptation by transferring beneficial traits between ... Artículo. 2012

Chemical signals act as the main reproductive barrier between sister and mimetic Heliconius butterflies
Colour pattern is the main trait that drives mate recognition between Heliconius species that are phylogenetically close. However, when this cue is compromised such as in cases of mimetic, sympatric and closely related ... Artículo. 2020

Chromosomal rearrangements maintain a polymorphic supergene controlling butterfly mimicry
Supergenes are tight clusters of loci that facilitate the co-segregation of adaptive variation, providing integrated control of complex adaptive phenotypes1. Polymorphic supergenes, in which specific combinations of traits ... Artículo. 2011

Complex modular architecture around a simple toolkit of wing pattern genes
Identifying the genomic changes that control morphological variation and understanding how they generate diversity is a major goal of evolutionary biology. In Heliconius butterflies, a small number of genes control the ... Artículo. 2017

Correction: taxonomical over splitting in the Rhodnius prolixus (insecta: hemiptera: reduviidae) clade: are R. taquarussuensis (da Rosa et al., 2017) and R. neglectus (Lent, 1954) the same species?
The use of subtle features as species diagnostic traits in taxa with high morphological similarity sometimes fails in discriminating intraspecific variation from interspecific differences, leading to an incorrect species ... Artículo. 2019

Evolution of novel mimicry rings facilitated by adaptive introgression in tropical butterflies
Understanding the genetic basis of phenotypic variation and the mechanisms involved in the evolution of adaptive novelty, especially in adaptive radiations, is a major goal in evolutionary biology. Here, we used whole-genome ... Artículo. 2017

Evolutionary novelty in a butterfly wing pattern through enhancer shuffling
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. ... Artículo. 2016

Gene flow and Andean uplift shape the diversification of Gasteracantha cancriformis (Araneae: Araneidae) in Northern South America
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 ... Artículo. 2018

Gene flow and the genealogical history of Heliconius heurippa
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 and ... Artículo. 2008
