Balanced polymorphisms and their divergence in a Heliconius butterfly [PDF]

Ecology and Evolution, 2021
The evolution of mimicry in similarly defended prey is well described by the Müllerian mimicry theory, which predicts the convergence of warning patterns in order to gain the most protection from predators.

Major patterns in the introgression history of Heliconius butterflies [PDF]

eLife, 2023
A bstract Gene flow between species is an important evolutionary process that can facilitate adaptation and lead to species diversification. It also makes reconstruction of species relationships difficult.

Hybrid incompatibility is consistent with a hybrid origin ofHeliconius heurippaHewitson from its close relatives,Heliconius cydnoDoubleday andHeliconius melpomeneLinnaeus [PDF]

Journal of Evolutionary Biology, 2004
AbstractShared ancestral variation and introgression complicates the reconstruction of phylogenetic relationships among closely related taxa. Here we use overall genomic compatibility as an alternative estimate of species relationships in a group where divergence is rapid and genetic exchange is common.Heliconius heurippa, a butterfly species endemic ...

Quantifying visual acuity in Heliconius butterflies. [PDF]

Biol Lett, 2023
Abstract Heliconius butterflies are well-known for their colourful wing patterns, which advertise distastefulness to potential predators and are used during mate choice. However, the relative importance of different aspects of these signals will depend on the visual abilities of ...

Cortex cis-regulatory switches establish scale colour identity and pattern diversity in Heliconius

eLife, 2021
In Heliconius butterflies, wing colour pattern diversity and scale types are controlled by a few genes of large effect that regulate colour pattern switches between morphs and species across a large mimetic radiation. One of these genes, cortex, has been

Oviposition behavior is not affected by ultraviolet light in a butterfly with sexually‐dimorphic expression of a UV‐sensitive opsin

Ecology and Evolution, 2023
Animal vision is important for mediating multiple complex behaviors. In Heliconius butterflies, vision guides fundamental behaviors such as oviposition, foraging, and mate choice.

The comparative landscape of duplications in Heliconius melpomene and Heliconius cydno [PDF]

Heredity, 2016
AbstractGene duplications can facilitate adaptation and may lead to interpopulation divergence, causing reproductive isolation. We used whole-genome resequencing data from 34 butterflies to detect duplications in two Heliconius species, Heliconius cydno and Heliconius melpomene. Taking advantage of three distinctive signals of duplication in short-read

Transmisssion Dynamics of Enterococcus spp. Throughout the Heliconius erato phyllis (Lepidoptera; Nymphalidae) Life Cycle [PDF]

Environ Microbiol Rep
Enterococcus spp. dominate the gut microbiota of Heliconius erato phyllis, transmitted horizontally via host plants (Passiflora suberosa) and persisting through development. Multidrug‐resistant strains were found in larvae and plants, suggesting environmental reservoirs of antimicrobial resistance. This study reveals key microbial transmission dynamics

Selection on the wing in Heliconius butterflies [PDF]

BMC Genetics, 2011
To what extent population structure favours the establishment of new phenotypes within a species remains a fundamental question in evolutionary studies. By reducing gene flow, habitat fragmentation is a major factor shaping the genetic structuring of populations, favouring isolation of small populations in which drift may rapidly change frequencies of ...
