Rapid phenotypic change in a polymorphic salamander over 43 years.

Scientific reports - 22 Nov 2021

Hantak Maggie M, Federico Nicholas A, Blackburn David C, Guralnick Robert P

Abstract excerpt

Color polymorphic animals offer a unique system for studying intraspecific phenotypic responses to climate change. Discrete color morphs are easy to identify, and correlated trait responses of morphs can indicate how climate warming may facilitate long-term maintenance of polymorphisms. We use a historical dataset spanning 43 years to examine temporal shifts in color morph frequency and body size in response to...
