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 ...

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

Genomic hotspots for adaptation: the population genetics of Müllerian mimicry in the Heliconius melpomene clade. [PDF]

PLoS Genetics, 2010
Wing patterning in Heliconius butterflies is a longstanding example of both Müllerian mimicry and phenotypic radiation under strong natural selection. The loci controlling such patterns are "hotspots" for adaptive evolution with great allelic diversity ...

Mischocyttarus heliconius Richards 1941

, 2023
Key for identification of females of the species of the M. heliconius species group 1. Inner tarsal claw of hind leg without a noticeable subapical narrowing, its width fairly uniform to the tip, which is rounded (Figs. 17, 18); clypeus shape variable, more often subquadrate (Fig. 9, 10); clypeus rarely with silvery or whitish bristles (Fig.

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.

Conserved microbiota among young Heliconius butterfly species [PDF]

PeerJ, 2018
Background Insects are the most diverse group of animals which have established intricate evolutionary interactions with bacteria. However, the importance of these interactions is still poorly understood.

Major patterns in the introgression history of Heliconius butterflies

eLife, 2023
Gene flow between species, although usually deleterious, is an important evolutionary process that can facilitate adaptation and lead to species diversification. It also makes estimation of species relationships difficult.

Hybrid trait speciation andHeliconiusbutterflies [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2008
Homoploid hybrid speciation (HHS) is the establishment of a novel species through introgressive hybridization without a change in chromosome number. We discuss different routes by which this might occur and propose a novel term, ‘hybrid trait speciation’, which combines the idea that hybridization can generate adaptive novelty with the ‘magic trait ...

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 ...
