Abstract
In plethodontid salamanders, fecal pellets have a variety of behavioral functions related to chemical communication. We examined how fecal pellet mass in the Eastern Red-backed Salamander (Plethodon cinereus) varies with body size, color morph, and season. Fecal pellet mass increased with salamander size. Striped P. cinereus produced heavier fecal pellets than unstriped P. cinereus. Fecal pellet size tended to be greater in the spring than in the fall. Our results suggest further investigations of the factors governing fecal pellet size in plethodontid salamanders is warranted.
