This study examines dosage compensation mechanisms on ancestral and neo-Z chromosomes in butterflies, revealing varied gene expression patterns and highlighting the role of evolutionary history and gene function in shaping these mechanisms.

The paper investigates long-term gene flow barriers in hybridising swallowtail butterflies using whole-genome sequencing data, finding that regions of low recent hybridisation are enriched for long-term barriers to divergence.

The study presents a chromosome-level genome assembly of the Atlas blue butterfly, revealing constraints on chromosome evolution in Lepidoptera through extensive fission and fusion events.

The paper identifies genomic regions linked to hybrid inviability in butterflies by comparing allele frequencies in surviving and non-surviving F2 hybrids, showing these regions are in fast-evolving, low-recombination areas with chromosome fusions.

This study uses genomic data to analyze the phylogenetic relationships, population structure, and ecological differentiation of the Pieris napi species group in the Western Palaearctic, revealing two main clades and key climatic drivers of adaptation.

The paper presents the reference genome of the Spanish Moon Moth Graellsia isabellae, which helps resolve its scientific name and supports genetic monitoring of the species.

This study identifies gene expression changes in painted lady butterflies in response to environmental cues, highlighting pathways involved in migration and reproduction.

The paper studies neo-sex chromosome evolution in butterflies, finding that rare recombination can reverse degradation and create divergence plateaus on neo-W chromosomes.

The paper examines karyotype variation in Polyommatine butterflies, finding that the W sex chromosome remains intact despite chromosome fragmentation.

The paper examines the faster-Z effect in Leptidea sinapis, showing that neo-Z chromosomes evolve at different rates due to varying selective pressures and W gametolog presence.

The paper investigates meiotic drive in butterfly hybrids, finding transmission biases that favor or oppose chromosome fusions, suggesting meiotic drive can both promote and hinder karyotypic evolution.

This study investigates recombination rate variation in butterflies, finding bimodal patterns in large chromosomes, lower rates in subtelomeres, and associations with transposable elements and gene activity.

This study develops a high-density linkage map and annotates the genome of the painted lady butterfly, revealing gene family expansions and recombination rate variation linked to genomic features and lifestyle adaptations.

This study examines genetic diversity in European butterflies and finds it correlates with body size and genetic map length, not population size or fecundity.

The paper uses citizen science to collect genetic data on the invasive butterfly Pieris rapae, revealing its global spread through human activities and four founding events over 160 years.
