The paper shows that the Papilio alphenor supergene evolved through the recruitment of six new cis-regulatory elements that enable allele-specific dsx expression.

The paper investigates whether host shifts to new trees, organs, or gall morphologies drive diversification in oak gall wasp kleptoparasites, finding that most divergence events correlate with shifts to non-ancestral galls.

This study shows how co-opted doublesex gene expression alters conserved signaling pathways to develop novel mimetic butterfly wing patterns.

The paper reports rearing records of arthropods from over 527,000 oak galls, identifying 151,075 animals and providing ecological and phylogenetic insights into gall-associated taxa.

This study investigates host shifts in Nearctic oak gall wasps and finds frequent shifts between host plants and organs, suggesting host shifts drive speciation in this group.

The study reveals that the parasitic wasp Ormyrus labotus, considered a generalist, is actually a complex of multiple specialized species, highlighting the limitations of morphological classification.

The paper examines host range and diversification in Synergus wasps using DNA barcodes, morphology, and ecology to identify species and assess host associations.
