Understanding how communication systems evolve across heterogeneous environments requires examining multiple signalling modalities. In 2017 and 2018, we examined geographic variation in chemical sign...

The way organisms perceive the world influences their evolution. Many animals detect ultraviolet (UV) light invisible to humans, creating sensory c...

Two new studies into lizard colors reveal how one species maintains its colorful diversity while others are losing their ancient colors.

A new study has uncovered several instances of wood warblers — some of the most colorful birds in North America — passing color-related genes to other wood warbler species, including those that are no...

For over a century, evolutionary biologists have been motivated to understand the mechanisms through which organisms adapt to their environments. Coloration and pigmentation are remarkably variable wi...

Abstract. Sexual conflict frequently gives rise to adaptations that increase male reproductive success at the expense of harming females (“male harm”) and

The insects’ brilliant hues evolved in lush ecosystems to help them survive. Now they are becoming more muted to adapt to degraded landscapes – and they are not the only things dulling down

Wall lizards' ventral coloration undergoes cryptic ontogenetic color changes invisible without UV vision. We tracked wall lizards from hatching to one year of age. Spectrophotometry and visual modeli...

Abstract. Venoms have traditionally been studied from a proteomic and/or transcriptomic perspective, often overlooking the true genetic complexity underlyi

White stork populations in Iberia are undergoing a profound change in their migratory patterns, becoming mostly resident. By combining census data, GPS-tracking and genomic analyses, Andrade et al. l....

Communications Biology - Mutations in polyketide synthase (PKS) disrupt psittacofulvin pigment production in parrots, altering feather hues. Seven unique variants in multiple conserved domains...
