Polygenic basis of incipient reproductive isolation in hybridizing populations is revealed by pangenomic and epigenetic divergence

The paper reveals widespread genomic and epigenetic divergence in Heliconius erato populations, showing polygenic barriers to gene flow rather than few major-effect loci.

Genetic basis of an adaptive polymorphism controlling butterfly silver iridescence

This study identifies the genetic basis of silver iridescence polymorphism in Mormon Fritillary butterflies, linking it to the optix gene and showing evidence of selection and introgression.

Flexible color segmentation of biological images with the R package recolorize

The paper introduces the R package recolorize for flexible color segmentation of biological images, improving upon existing methods by handling biological and technical variation and enabling downstream analyses.

A butterfly pan-genome reveals a large amount of structural variation underlies the evolution of chromatin accessibility

The paper characterizes structural variation in Heliconius butterfly genomes and links it to chromatin accessibility and cis-regulatory elements.

Multiple loci control eyespot number variation on the hindwings of Bicyclus anynana butterflies

The paper investigates the genetic basis of eyespot number variation in Bicyclus anynana butterflies, finding that multiple loci, not single master regulators, influence this trait.

The genetic basis of hindwing eyespot number variation in Bicyclus anynana butterflies

The paper investigates the genetic basis of hindwing eyespot number variation in Bicyclus anynana butterflies, finding moderate heritability and multiple loci associated with eyespot number.

Patternize: An R Package For Quantifying Color Pattern Variation

patternize quantifies color pattern variation across organisms using image alignment and segmentation, enabling comparison and analysis through PCA and heatmaps.
