This study examines the relationship between diversification and phenotypic evolution in Ithomiini butterflies, finding trait-specific and geographically structured links between forewing shape evolution and diversification.

The paper uses computer vision to analyze wing color patterns in Nymphalid butterflies, finding that aposematism is the dominant axis of phenotypic diversification.

This study examines spatial patterns of Mullerian mimicry in Neotropical butterflies, revealing convergent climatic niches and vulnerability to climate change.

This study examines two Neotropical butterfly radiations, revealing high rates of hybridization and chromosomal rearrangements as drivers of diversification.

This study reconstructs the phylogeny of Neotropical limenitidine butterflies to explore the evolution of mimicry patterns and their relationship with speciation.

This study examines how mutualistic Mullerian mimicry influences macroevolutionary diversification patterns in Ithomiini butterflies, finding that color pattern age drives species richness but not phylogenetic diversity.

The paper shows that nuclear-encoded universal single-copy orthologs (USCOs) outperform mitochondrial DNA barcoding in species discrimination and taxonomic assignment across metazoans.
