Biofluorescent sexual dimorphism revealed in a southern Appalachian endemic salamander, Plethodon metcalfi by Cox, Jonathan L., Fitzpatrick, Benjamin M.

“…Biofluorescence occurs when a living organism absorbs high energy light and reemits it at longer wavelengths. Many species within clades of vertebrates are…”

Underappreciated Consequences of Phenotypic Plasticity for Ecological Speciation by Fitzpatrick, Benjamin M.

“…Phenotypic plasticity was once seen primarily as a constraint on adaptive evolution or merely a nuisance by geneticists. However, some biologists promote…”
