Amphibians can be partitioned among ponds based on their ability to tolerate fish predation. However, even among fish-tolerant species susceptibility to fish predators varies, with consequences for both prey and predator. We examined the effects of Bluegill (Lepomis macrochirus) and tadpole density on two fish-tolerant species of tadpoles (American Toad, Anaxyrus americanus; American Bullfrog, Lithobates catesbeianus...
Nitrogen pollution as a result of agricultural runoff and atmospheric deposition is a major challenge to aquatic ecosystems, and is likely to increase in the future. Nitrogenous pollutants are potential stressors of amphibian larvae through their toxicological impacts on individuals; however, they may also increase primary productivity. We examined how such an anthropogenic stressor could influence...
