Description

Color polymorphic species, where multiple color phenotypes (i.e., morphs) coexist within the same population, are extremely common in nature. In the salamander genus Plethodon, at least ten species exhibit a striped/unstriped color polymorphism, while closely related species are fixed for either morph. In a single species, the Eastern Red-backed Salamander (Plethodon cinereus), previous work has indicated that morphs diverge in climatic niche use. However, the magnitude and direction of color morph-climate associations has varied across studies. Further, little research has examined the relationship between climate and color morph in the nine other color polymorphic Plethodon. Here, I scored color phenotypes from >65,000 web-based georeferenced community science images of color polymorphic Plethodon. With this extensive color morph dataset, I quantified the climatic niche of each species and their color morphs when applicable and utilized a comparative approach to examine patterns of climatic niche overlap, niche breadth, and potential responses to future climate change.
