Genomic evidence reveals three sequential W-autosome fusions in Heliconius butterflies

The paper identifies three sequential W-autosome fusions in Heliconius butterflies, revealing their role in adaptive radiation and sex chromosome evolution.

Effects of temperature on the development of Heliconius erato butterflies

This study examines how different developmental temperatures affect survival and morphology in Heliconius erato butterflies, finding higher egg and larval mortality at higher temperatures and morphological changes in adults.

Repeated genetic adaptation to high altitude in two tropical butterflies

This study identifies genetic regions under selection in two tropical butterflies adapted to high altitude, showing that standing variation and introgression from high-altitude specialists contribute to parallel adaptation.

Genomics of altitude-associated wing shape in two tropical butterflies

This study investigates the genomic basis of altitude-associated wing shape differences in two Heliconius butterfly species, finding a polygenic basis and identifying candidate genes involved in wing morphogenesis.

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

The paper identifies cis-regulatory regions controlled by cortex that determine scale color identity and pattern diversity in Heliconius butterflies through CRISPR perturbations and chromatin accessibility analysis.

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

This study investigates intraspecific variation in cyanogenic toxicity in Heliconius erato, finding substantial variation and potential for adaptive evolution despite limited dietary influence.

Microclimate buffering and thermal tolerance across elevations in a tropical butterfly

This study examines microclimate buffering and thermal tolerance in tropical butterflies across elevations, finding that high-elevation populations show reduced heat tolerance but plasticity in common-garden conditions.

Species specificity and intraspecific variation in the chemical profiles of Heliconius butterflies across a large geographic range

The paper examines chemical profile divergence in Heliconius butterflies, finding strong interspecific differences and some intraspecific variation, with implications for species recognition.

Altitude and life-history shape the evolution of Heliconius wings

This study examines how altitude and life-history traits influence wing shape and size divergence in Heliconius butterflies, revealing novel adaptive morphological patterns beyond coloration.
