Abstract excerpt

The strawberry poison frog, Oophaga pumilio, is a striking example of natural color variation, making it a valuable system for studying the genetic and evolutionary mechanisms underlying phenotypic diversity. While most populations of this poisonous frog are bright red, frogs from Bocas del Toro Province, Panama, exhibit remarkable variation in color, both within and among island populations. This diversity in...
