Quantifying visual acuity in Heliconius butterflies

The paper measures visual acuity in Heliconius butterflies using behavioural and morphological methods, finding higher acuity in males and implications for predator-prey interactions.

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

The study tests if UV vision affects oviposition in Heliconius butterflies, finding no impact on oviposition attempts or egg numbers.

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.

Selection and gene flow define polygenic barriers between incipient butterfly species

This study investigates genomic divergence and introgression between incipient butterfly species, finding that polygenic barriers and selection, rather than isolation, drive genome-wide patterns of divergence.

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.

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.
