Plumage diversity without differential expression of pigmentation genes in a rapid avian radiation

Maria Recuerda, Marcio Repenning, Matthew B Toomey…·Leonardo Campagna

The paper investigates plumage diversity in Capuchino Seedeaters by analyzing gene expression and variants, finding that pigmentation differences arise from regulatory changes rather than differential gene expression.

A pangenomic approach reveals the sources of genetic variation fueling the rapid radiation of Capuchino Seedeaters

María Recuerda, Simón Kraemer, Jonas Rafael Rodrigues Rosoni…·Leonardo Campagna

The paper uses a pangenome of Capuchino Seedeaters to show that small SNPs and indels, not large structural variants, drive species divergence and plumage diversity.

Repeated divergent selection on pigmentation genes in a rapid finch radiation driven by sexual selection

Leonardo Campagna, Márcio Repenning, Luis Fabio Silveira…·Irby J Lovette

The paper identifies divergent genomic regions in capuchino finches linked to pigmentation genes, showing independent selection on regulatory elements driving phenotypic diversity.
