Abstract
Regions downwind of industrial and agricultural pollution receive high amounts of nitrogen (N) deposition. Some forested regions now exhibit symptoms on N saturation, which is N availability in excess of biotic demand. This phenomena and the evidence that trees alter soil in ways that may influence N saturation is the basis of my research. My thesis consists of three parts: (1) Testing the association between tree species and soil properties: Can larger-scale patterns be found under individual trees?; (2) Phosphomonesterase activity in violets (Viola rotundifolia) found in watersheds exhibiting varying levels of nitrogen availability: What lies beyond nitrogen saturation?; and (3) Nutrient limitation in soils exhibiting differing nitrogen availabilities: A greenhouse- and field-based assessment.
