Effects of Plant Diversity and Functional Identity on Ecosystem Nitrogen Retention and Removal in Great Lakes Wetlands

The central theme of the proposed research program is to investigate   the effects of plant community composition on the ability of Great   Lakes wetlands to retain and remove nitrogen. The invasion of many   Great Lakes wetlands by aggressive invasive species, such as   Phalaris arundinacea and Phragmites australis, has resulted in the   introduction of novel plant traits that can influence key nitrogen   transformation pathways (e.g. nitrification, mineralization, and   denitrification). This work aims to determine if the plant traits of   the dominant wetland species, such as plant N uptake, biomass   production, litter quantity and quality, and rooting depth affects   the rate and dominance of the above mentioned nitrogen   transformation pathways. It will also be determined if plant   diversity affects these ecosystem level processes.    (AIS); (aquatic invasive species); (ANS); (aquatic nuisance   species); (exotic species); (invasive plant); (invasive plants);   (Phalaris arundinacea); (reed canary grass); (phragmite);   (phragmites); (Phragmites australis); (nitrogen); (nitrification);   (denitrification); (eutrophication); (algal bloom); (algal blooms);   (nutrient loading); (nutrient loadings)
