Multiple Mechanisms of Photoreceptor Spectral Tuning in Heliconius Butterflies [PDF]

, 2022
The evolution of color vision is often studied through the lens of receptor gain relative to an ancestor with fewer spectral classes of photoreceptor. For instance, in Heliconius butterflies, a genus-specific UVRh opsin duplication led to the evolution ...

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

Ecology 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.

Polyphyly and gene flow between non-sibling Heliconius species

, 2006
Background: The view that gene flow between related animal species is rare and evolutionarily unimportant largely antedates sensitive molecular techniques.

Two sisters in the same dress: Heliconius cryptic species

BMC 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

Phylogenetic Codivergence Supports Coevolution of Mimetic Heliconius Butterflies

, 2012
The unpalatable and warning-patterned butterflies _Heliconius erato_ and _Heliconius melpomene_ provide the best studied example of mutualistic Müllerian mimicry, thought – but rarely demonstrated – to promote coevolution.

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

G3: 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.

Waves of range dynamics and gene flow characterize the biogeographic history of Litsea elongata, a dominant tree in East Asian evergreen broadleaved forests

PLANTS, PEOPLE, PLANET, EarlyView.
Evergreen broadleaved forests (EBLFs) represent an iconic vegetation type in subtropical montane East Asia, but they are experiencing intensifying anthropogenic pressure and increasing habitat fragmentation. Here, using a dominant and widespread tree species characteristic of East Asian EBLFs, we examine its phylogeographic history and evaluate what it

Absence of crossing-over in female butterflies (Heliconius) [PDF]

Heredity, 1975
Absence of recombination between linked markers in female Heliconius is suggested by coupling backcross broods in H. erato, by a repulsion F2 in H. melpomene, and by other crosses with this species. No recombinants have been found in the offspring of doubly heterozygous females in either species.

Sex-related interannual plasticity in wing morphological design in Heliconius charithonia enhances flight metabolic performance.

PLoS ONE, 2020
Flight morphological variations and its consequences on animal performance are common in winged insects. In the butterfly Heliconius charithonia, sex-related differences in the wing morphological design have been described resulting in differences in ...
