Atmospheric deposition of combined nitrogen in the Cape Metropolitan Area: a threat to a species rich ecosystem?
… approaches were used in order to gauge levels of atmospheric N deposition to the natural vegetation of the Cape Metropolitan Area (CMA). In the first approach, bulk collectors were constructed and set up at five sites around the CMA in order to trap atmospheric deposition for chemical analysis. In …

Interactive effects of hemlock mortality and nitrogen availability on nutrient pools and fluxes in the southern Appalachian Mountains
… (low, mid, high) subjected to increasing atmospheric N deposition where hemlock was declining or absent (as reference), in western North Carolina. Nutrient pools varied substantially with elevation and increasing N availability; total forest floor and mineral soil N increased (p<0.0001, …

Impacts of Best Management Practices on Nitrogen Discharge From a Virginia Coastal Plain Watershed
… corn and split N application. The role of atmospheric N (atm-N) deposition (dry+wet) in masking the effects of BMPs on watershed N loading was also investigated. Nitrogen retention and discharge from the forest areas in the NC watershed were simulated using the 5-year water and N input and …

Developing Critical Loads and Dynamic Critical Loads for Acidification for Watersheds in the Adirondack region of New York and Great Smoky Mountain National Park (GRSM)
… impacted by high sulfate, nitrate and ammonium deposition. In this study, a biogeochemical model (PnET-BGC) was applied to 20 watersheds in the Adirondack region and 12 watersheds in Great Smoky Mountain National Park (GRSM) to calculate CLs and DCLs. I evaluated ecosystem changes in response to …

Ectomycorrhizal associations in tropical montane forest: insights into their influence on nutrient cycling and functional responses to soil fertility
… I predicted increase in N availability due to atmospheric N deposition, could potentially alter the interaction between EM fungi and their host plant potentially leading to biotic and abiotic changes in the ecosystem.

Estimation and mitigation assessment of N₂O emission and nitrate leaching in a mountainous catchment in South Korea using the LandscapeDNDC model
… altitudes and thus different exposure to atmospheric N deposition (24 - 51 kg N ha-1). Application of the adjusted meteorological data showed better prediction of soil temperature and water content from rows covering with plastic mulch as compared to application of the actual weather data …
