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.

This study examines host plant preference and offspring performance in the butterfly Aricia artaxerxes, finding that females prefer a less optimal host plant due to its abundance and geographic distribution.

The paper presents the first chromosome-level genome assembly for the marbled teal, enabling analyses of inbreeding and genetic variation in this threatened species.

The paper identifies sequence features associated with chromosomal rearrangements in Leptidea butterflies using genome assemblies and re-sequencing data.

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.

The paper uses isotope geolocation and genome-wide analysis to show that short- and long-distance migratory V. cardui butterflies are genetically undifferentiated, suggesting migration distance is environmentally plastic.

The paper identifies a hybrid butterfly lineage in the Baltic Sea, showing it originated from hybridization between two non-sister species and persisted through climate change.

The paper describes the European Reference Genome Atlas (ERGA) pilot project, which tests a decentralized model for producing high-quality reference genomes across 98 European 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 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.
