Variation in Leg Color Does Not Influence Courtship Success in the Red-legged Salamander, Plethodon shermani

Creator:: Baggett, Christy, Eddy, Sarah, and Houck, Lynne
Abstract:: The ritualized courtship of the Red-legged salamander, Plethodon shermani, has been studied extensively. Males and females possess brightly colored red legs, but little is known about the implications of this coloration on mate choice. An alternative hypothesis is that coloration may be used as a warning signal to predators. Animals...
