Theses, Dissertations and Capstones
This thesis contributes to on-going research at Marshall University on effects of excess nitrogen (N) deposition on hardwood forests. Excess N can decrease plant biodiversity and enhance loss of nutrients (e.g., Ca++). Preliminary results have suggested that excess N has increased cover of Rubus (blackberry) in the herbaceous layer. The purpose of this study was to quantify the response of Rubus to the N treatment, relating Rubus cover to species richness and using foliar analysis to examine effects on nutrient availability. It is expected that increased Rubus will decrease biodiversity by eliminating N-efficient species, and that added N …
