Competitive control of invasive vegetation: a native wetland sedge suppresses Phalaris arundinacea in carbon-enriched soil

(Phalaris arundinacea L.), and Native Plants in Wisconsin Wet Meadows

1 Corresponding author: [email protected]; (608) 238-4673; fax: (608) 262-7509 ABSTRACT: Twelve wet meadows in Dane County, Wisconsin showed vegetation patterns that correlate with hydrologic disturbance and presence of a clonal invasive grass, Phalaris arundinacea L., at two scales, 4500-m2 (0.45 ha) “sites” and 1-m2 plots. Sites with indicators of hydrologic disturbance had lower species rich...

Correlation of Soil Nutrient Characteristics and Reed Canarygrass (Phalaris arundinacea: Poaceae) Abundance in Northern Illinois (USA)

—Phalaris arundinacea L. (reed canarygrass) is an aggressive graminoid species that invades wetlands in much of the northern United States. In areas previously used for agriculture and other recently disturbed habitats, P. arundinacea out-competes the native flora and creates monocultures, which reduce biodiversity and alter ecosystem functioning. Much research has focused on the growth respons...

An integrated model of soil, hydrology, and vegetation for carbon dynamics in wetland ecosystems

[1] Wetland ecosystems are an important component in global carbon (C) cycles and may exert a large influence on global climate change. Predictions of C dynamics require us to consider interactions among many critical factors of soil, hydrology, and vegetation. However, few such integrated C models exist for wetland ecosystems. We developed a simulation model, Wetland-DNDC, for C dynamics inclu...

Carbon dioxide assimilation by a wetland sedge canopy exposed to ambient and elevated CO

1. The wetland sedge Scirpus olneyi Gray displays fast rates of CO 2 assimilation and responds positively to increased atmospheric CO 2 concentration. The present study was aimed at identifying the ecophysiological traits specific to S. olneyi that drive these CO 2 -assimilation patterns under ambient and elevated CO 2 conditions. 2. The net ecosystem exchange (NEE) of CO 2 between S. olneyi co...
