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.

This study shows house finches do not use CYP2J19/BDH1L to produce red plumage, suggesting an alternative pathway for 3-OH-echinenone synthesis.

The study examines how light environment and seasonal changes affect chromophore usage and opsin expression in red shiners, finding a temperature-dependent trade-off and limited opsin variation.

This study shows that captivity in cages reduces red carotenoid circulation and increases mitochondrial respiratory rates in house finches, supporting a link between carotenoid metabolism and mitochondrial function.

This study identifies the developmental origin and genetic mechanisms of red coloration in D. albolineatus, showing parallels with bird coloration mechanisms.

The paper investigates how thyroid hormone regulates different maturation paths in zebrafish pigment cell lineages through transcriptomic profiling and trajectory analysis.
