Abstract: The complexity of food webs and interactions between predators and prey is an area of ecology that still holds many questions for researchers.  This study examined the effects of a wolf spider (Pirata sp.) and a terrestrial salamander (Plethodon cinereus) on the composition of a forest floor community.  A 2 x 3 factorial design was used to determine how spiders, juvenile salamanders, and adult salamanders affect the invertebrate community of the forest floor and to discern any interactions between these two species of generalist predators.  Although fewer invertebrates were found in treatments in which salamanders and spiders were present, there was no significant effect of either predator or the combination of predators on the total  abundance of invertebrates in the leaf litter community.  Salamanders significantly reduced the relative abundances of invertebrates in the smallest size class (less than 1 mm), while the presence of spiders had a significantly positive effect on relative abundance of this size class of prey.  These results suggest that salamanders feed on very small prey, and have a direct (negative) effect on their numbers.  It is likely that spiders feed on a larger range of prey, and therefore may be consuming predators.  Spider predation on other predators may explain the indirect (positive) effect of spiders on the number of invertebrates less than 1 mm.
