Description
ABSTRACT--Salamanders inhabiting splash zones of seepage areas have access to both aquatic and terrestrial prey. Stomach-content analyses of Cannon County dusky salamander populations indicate that postmetamorphic individuals consume a variety of invertebrate prey, and the diet varies with prey seasonal availability and abundance. Of the 958 prey items identified from 100 salamanders, 52% of the prey were aerial insects, 29% aquatic insects and other arthropods, and 19% terrestrial arthropods. The aquatic portion of the diet was greatest during autumn (42%) and early winter (43%) and decreased through early and late spring (31% and 10%, respectively). Although a large body of evidence indicates that desmognathine salamanders feed on aquatic prey, little is known about the mechanism of prey capture for most species, including D. fuscus. **********
