Estimation of the Spontaneous Mutation Rate in Heliconius melpomene [PDF]

open access: yesMolecular Biology and Evolution, 2014
We estimated the spontaneous mutation rate in Heliconius melpomene by genome sequencing of a pair of parents and 30 of their offspring, based on the ratio of number of de novo heterozygotes to the number of callable site-individuals. We detected nine new mutations, each one affecting a single site in a single offspring.

Evolutionary and ecological processes influencing chemical defense variation in an aposematic and mimetic Heliconius butterfly [PDF]

open access: yesPeerJ, 2021
Chemical defences against predators underlie the evolution of aposematic coloration and mimicry, which are classic examples of adaptive evolution. Surprisingly little is known about the roles of ecological and evolutionary processes maintaining defence ...

Signatures of selection in loci governing major colour patterns in Heliconius butterflies and related species

open access: yesBMC Evolutionary Biology, 2010
Background Protein-coding change is one possible genetic mechanism underlying the evolution of adaptive wing colour pattern variation in Heliconius butterflies. Here we determine whether 38 putative genes within two major Heliconius patterning loci, HmYb

The evolution of adult pollen feeding did not alter postembryonic growth in Heliconius butterflies

open access: yesEcology and Evolution, 2022
For many animals, the availability and provision of dietary resources can vary markedly between juvenile and adult stages, often leading to a temporal separation of nutrient acquisition and use.

Mischocyttarus heliconius Richards 1941

open access: yes, 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.

The Scent Chemistry of Heliconius Wing Androconia

open access: yesJournal of Chemical Ecology, 2017
Neotropical Heliconius butterflies are members of various mimicry rings characterized by diverse colour patterns. In the present study we investigated whether a similar diversity is observed in the chemistry of volatile compounds present in male wing androconia. Recent research has shown that these androconia are used during courting of females.

Two sisters in the same dress: Heliconius cryptic species

open access: yesBMC Evolutionary Biology, 2008
Background Sister species divergence and reproductive isolation commonly results from ecological adaptation. In mimetic Heliconius butterflies, shifts in colour pattern contribute to pre- and post-mating reproductive isolation and are commonly correlated

Major Improvements to the Heliconius melpomene Genome Assembly Used to Confirm 10 Chromosome Fusion Events in 6 Million Years of Butterfly Evolution

open access: yesG3: Genes, Genomes, Genetics, 2016
The Heliconius butterflies are a widely studied adaptive radiation of 46 species spread across Central and South America, several of which are known to hybridize in the wild.

Metamorphosis of a butterfly-associated bacterial community. [PDF]

open access: yesPLoS ONE, 2014
Butterflies are charismatic insects that have long been a focus of biological research. They are also habitats for microorganisms, yet these microbial symbionts are little-studied, despite their likely importance to butterfly ecology and evolution.

Hybrid trait speciation andHeliconiusbutterflies [PDF]

open access: yesPhilosophical 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 ...
