Phytodegradation of neonicotinoids in Cyperus papyrus from enzymatic and transcriptomic perspectives

Journal of Hazardous Materials
Neonicotinoids are widely used but environmentally hazardous insecticides. Constructed wetlands offer potential for neonicotinoid removal, but the corresponding metabolic pathways and mechanisms in wetland plants are incompletely understood. This study investigated the fate of six neonicotinoids and their metabolites in Cyperus papyrus, a common ...

Dissolved organic carbon in a tropical wetland dominated by Cyperus papyrus

Wetlands Ecology and Management, 2015
To improve understanding of carbon budgets in tropical wetlands, there is need to include estimates of fluxes of dissolved organic carbon (DOC) which are usually influenced by hydrological conditions. In this study, an assessment was made to test the hypotheses that tropical wetlands show significant fluvial losses of organic carbon and that these ...

CO2 and O2 transport in the aerenchyma of Cyperus papyrus L.

Aquatic Botany, 1995
Abstract Cyperus papyrus L. (papyrus) is an emergent wetland species with C 4 photosynthesis. Culms of papyrus possess numerous large intercellular air cavities and functional ‘Kranz’ chlorenchyma which are involved in CO 2 recycling in the culm. In darkness, the CO 2 concentration in the culms increased to 74 times that of the ambient air.

Standing biomass and carbon distribution in a papyrus (Cyperus papyrus L.) swamp on Lake Naivasha, Kenya

Journal of Tropical Ecology, 1997
ABSTRACTThe standing live biomass of papyrus swamps is high compared with most other communities dominated by herbaceous vegetation. For the first time, measurements of below-ground rhizome and root biomass are reported here, in addition to measurements of shoot biomass, for a papyrus swamp located on Lake Naivasha, Kenya. The ratio of rhizome and root

Effects of a cyperus papyrus L. swamp on domestic waste water

Aquatic Botany, 1985
Abstract The effectiveness of a papyrus swamp for the removal of nutrients from domestic waste water was investigated in a small tropical swamp in Kenya. The study was conducted in a man-made impoundment transformed into a swamp which receives sewage effluents discharged into a stream.

Impact of nanoplastics on the biodegradation, ecotoxicity, and key genes involved in imidacloprid metabolic pathways in papyrus (Cyperus papyrus L.)

Chemosphere
Both nanoplastics (NPs) and imidacloprid (IMI) are widely distributed in the environment and have attracted significant attention due to their adverse effects on ecosystems. Constructed wetlands have the potential to remove IMI, but there is still limited understanding of how wetland plants interact with IMI, especially when influenced by different ...

Nutrient release from swamp water, Cyperus papyrus L. organs and swamp sediments

Hydrobiological Bulletin, 1989
Nitrogen and phosphorus releases from swamp water,Cyperus papyrus plant organs and papyrus swamp sediments were investigated over five weeks. The release of nutrients by dissolution of decomposing organic matter was very important for the swamp water under the prevailing anaerobic conditions.
