Evolution of hybrid inviability associated with chromosome fusions

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.

Meiotic drive against chromosome fusions in butterfly hybrids

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.

Temporal Dynamics of Faster Neo-Z Evolution in Butterflies

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.

Nascent evolution of recombination rate differences as a consequence of chromosomal rearrangements

This study examines how chromosomal rearrangements affect recombination rates and genetic diversity in two wood white butterfly populations with distinct karyotypes.

Evolution of seasonal plasticity in response to climate change differs between life-stages of a butterfly

The paper examines how seasonal plasticity in different life stages of a butterfly evolves under climate change, finding divergent responses in larval development time and no change in pupal diapause.

High-density linkage maps and chromosome level genome assemblies unveil direction and frequency of extensive structural rearrangements in wood white butterflies (Leptidea spp.)

The paper generates genome assemblies and linkage maps for Leptidea species to study structural rearrangements, finding extensive fissions, fusions, and polymorphisms, with LINEs and LTR elements enriched at fusion breakpoints.

Timing of mating, reproductive status and resource availability in relation to migration in the painted lady butterfly, Vanessa cardui

This study investigates the oogenesis-flight syndrome in painted lady butterflies, finding that migration occurs during a pre-reproductive phase and that mating frequency correlates with host plant abundance.

Cryptic, extensive and non-random chromosome reorganization revealed by a butterfly chromonome

The paper reveals extensive, non-random chromosome reorganization in the green-veined white butterfly through fission and fusion events, despite maintaining a standard haploid chromosome count and gene collinearity.
