temperature and wetland plant species effects on wastewater treatment and root zone oxidation.	constructed wetlands are widely used for wastewater treatment, but there is little information on processes affecting their performance in cold climates, effects of plants on seasonal performance, or plant selection for cold regions. we evaluated the effects of three plant species on seasonal removal of dissolved organic matter (om) (measured by chemical oxygen demand and dissolved organic carbon) and root zone oxidation status (measured by redox potential [eh] and sulfate [so4(2-)]) in subsurfa ...	2002	12026068
screening the wetland plant species alisma plantago-aquatica, carex rostrata and phalaris arundinacea for innate tolerance to zinc and comparison with eriophorum angustifolium and festuca rubra merlin.	several wetland plant species appear to have constitutive metal tolerance. in previous studies, populations from contaminated and non-contaminated sites of the wetland plants typha latifolia, phragmites australis, glyceria fluitans and eriophorum angustifolium were found to be tolerant to high concentrations of metals. this study screened three other species of wetland plants: alisma plantago-aquatica, carex rostrata and phalaris arundinacea for innate tolerance to zinc. the degree of tolerance ...	2005	15589661
ammonium removal in constructed wetland microcosms as influenced by season and organic carbon load.	we evaluated ammonium nitrogen removal and nitrogen transformations in three-year-old, batch-operated, subsurface wetland microcosms. treatments included replicates of typha latifolia, carex rostrata, and unplanted controls when influent carbon was excluded, and c. rostrata with an influent containing organic carbon. a series of 10-day batch incubations were conducted over a simulated yearlong cycle of seasons. the presence of plants significantly enhanced ammonium removal during both summer (24 ...	2005	15921269
influences of wetland plants on weathered acidic mine tailings.	establishment of carex rostrata, eriophorum angustifolium and phragmites australis on weathered, acidic mine tailings (ph approximately 3) and their effect on ph in tailings were investigated in a field experiment. the amendments, sewage sludge and an ashes-sewage sludge mixture, were used as plant nutrition and their influence on the metal and as concentrations of plant shoots was analysed. an additional experiment was performed in greenhouse with e. angustifolium and sewage sludge as amendment ...	2006	16584823
rhizome phyllosphere oxygenation in phragmites and other species in relation to redox potential, convective gas flow, submergence and aeration pathways.	underground rhizomes of emergent aquatic macrophytes are important for perennation, vegetative spread, competition and anchorage. in four species we examined the potential for the development of oxidized phyllospheres around rhizome apical buds, similar to the protective oxygenated rhizospheres around roots. redox potentials and polarographic measurements of radial oxygen loss were recorded using platinum cathodes around the apical buds. the aeration pathway from atmosphere to phyllosphere was i ...	2006	17096797
the distribution of (137)cs, k, rb and cs in plants in a sphagnum-dominated peatland in eastern central sweden.	we record the distribution of (137)cs, k, rb and cs within individual sphagnum plants (down to 20cm depth) as well as (137)cs in vascular plants growing on a peatland in eastern central sweden. in calluna vulgaris(137)cs was mainly located within the green parts, whereas andromeda polifolia, eriophorum vaginatum and vaccinium oxycoccos showed higher (137)cs activity in roots. carex rostrata and menyanthes trifoliata showed variable distribution of (137)cs within the plants. the patterns of (137) ...	2010	19889484
