Salamander communities have been excellent model systems for investigating the effects of competition and predation on community structure. Researchers have frequently examined the roles of competition and predation in terrestrial or semi-aquatic communities of salamanders, but have rarely examined the influence of these factors between these communities. We conducted mesocosm and laboratory behavioral experiments (1) to test hypotheses, derived from by a previous laboratory study, in a semi-natural setting and (2) to formulate new hypotheses regarding novel species-pair combinations. Our mesocosm experiments did not support a previous hypothesis of predation by Desmognathus fuscus (a semi-aquatic species) on Plethodon cinereus (a terrestrial species), but did support a prediction that P. cinereus would avoid D. fuscus. We predicted that behavioral experiments between pairs of semi-aquatic species would demonstrate predatory behavior by D. fuscus toward E. cirrigera and aggressive behavior by D. ochrophaeus toward Eurycea cirrigera; we did not find strong evidence for either predation or aggression. This finding was surprising given the similar activity patterns and dietary habits of these species. Although we predicted that Desmognathus might influence local distributions of heterogeneric salamanders through interspecific aggression in a manner similar to that seen within this genera, we found that both D. fuscus and D. ochrophaeus displayed much less aggression than expected. However, D. fuscus, in particular, appears to induce avoidance behavior in both P. cinereus and E. cirrigera without evidence of predation or excessive aggression, indicating that interference competition may be an important factor in structuring plethodontid communities.
