Afternoon T: testosterone level is higher in red than yellow male polychromatic lizards.

Physiology & behavior - 15 Aug 2007

Olsson Mats, Healey Mo, Astheimer Lee

Abstract excerpt

Recent work on within-species polymorphism across a broad range of taxa has renewed and considerably increased the attention to this classic evolutionary area, notably in lizard species where colors covary with reproductive strategies. We demonstrate elsewhere that red-headed males beat yellow-he...
