From May to October in 1997, the plant, soil and logging water in the wetlands were sampled monthly, and their P and K concentrations were measured. With the method of one-factor non-linear regression analysis, the seasonal dynamics of P and K in two types of wetland i.e., in Carex
Two plant communities, both dominated by Carex sempervirens but growing at different altitudes of the Northern Calcareous Alp region (IS: 600 m; KS: 1200 m) and one Carex ferruginea - dominated community (KC: 1200 m) are compared as to changes in dry matter, nitrogen, phosphorus, and potassium
In this study we analysed the impact of water regime and soil nutrients on the clonal diversity and genetic variation of the sedge Carex nigra in a central alpine fen. For our analysis, we established 16 study plots randomly distributed over the fen. We determined the exact elevation of each
Four typical wetland types (i.e. wetlands with the following dominant plant species: Calamagrostis angustifolia + Salix brachypoda, Calamagrostis angustifolia, Carex lasiocarpa and Phragmites australis) of the Honghe reserve in Sanjiang Plain were studied to investigate the distribution of soil
1. A plot of the Caricetum firmae in the Northern Calcareous Alps (at 2,160 m above sea level) was investigated during the growing season 1973 with regard to dry matter, nitrogen, phosphorus, and potassium content of overground and underground phytomass, including accumulated litter. 2. Compared to
This study investigated plant growth, nutrient partitioning and total nutrient uptake by tall sedge (Carex appressa) plants in two large-scale Constructed Floating Wetlands (CFW1 and CFW2). These CFWs were installed to treat stormwater runoff discharging into a newly-constructed 2.6-ha lake during
