Bioresource Technology, 2010
In this study, the pilot-scale constructed wetlands were fed with low-strength domestic wastewater to investigate the energy-capturing efficiency and plant productivity. Papyrus was a selected emergent macrophyte planted in the systems. The wastewater was intermittently fed to the systems, corresponding to the organic loading rates of 10, 16, 31, and ...

Primary production in papyrus (Cyperus papyrus L.) of Rubondo Island, Lake Victoria, Tanzania
Wetlands Ecology and Management, 2007Above- and below-ground production and morphological characteristics of papyrus wetlands were measured at monthly intervals from July 2005 to June 2006 at Rubondo Island, Lake Victoria, Tanzania. The average value of live culm biomass (5,789 ± 435 g DW m−2) was higher than that of umbel biomass (2,902 ± 327 g DW m−2) by 50%.

Chemical Diversity of Essential Oils fromCyperus articulatus, Cyperus esculentusandCyperus papyrus
Journal of Essential Oil Bearing Plants, 2014AbstractGas chromatography mass spectrometry was used to analyze the essential oil of three common Cyperus species grown in Egypt. The essential oils were obtained from the tubers and aerial parts of the plants using either hydrodistillation or head space analysis.

Effects of harvesting Cyperus papyrus in undisturbed wetland, Lake Naivasha, Kenya
Hydrobiologia, 2011In many parts of the world and especially in Africa, wetland plants are harvested to support livelihoods. As such, removal of biomass may have an impact on the standing biomass which could affect primary productivity, a fundamental biological process supporting trophic levels.

Arthropod Succession and Diversity in Umbels of Cyperus papyrus L.
Biotropica, 1981The arthropods of umbels of papyrus (Cyperus papyrus L.) were collected from three sites in the Upemba Swamp region of the Zaire River. Abundance and diversity of arthropods increased with age of umbel and with the purity and vigor of the papyrus stand. Herbivores predominated in the early age classes, predators and detritivores in the later ones. Ants

Control of the Stem Borer Bactra verutana on Cyperus papyrus
Journal of Economic Entomology, 1964Larvae of the oleuthreutid moth Bactra verutana Zeller feed on the leaves and bore into the stems and crown of Cyperus papyrus , a popular landscaping plant in southern California. Effective control on plants grown in 6-in. (1-gal) cans was obtained with a drenching spray of dimethoate (0.5 lb dimethoate/100 gal) and ¼ teaspoonful of 5% phorate ...

Techniques for discriminating species in swamp wetlands are critical for rapid wetlands assessment and proactive management. In this study, we tested whether field spectrometry could discriminate between papyrus swamp and its co-existence species (Phragmites australis, Echinochloa pyramidalis, and Thelypteris interrupta).

Oecologia, 1984
The diurnal course of water potential, stomatal conductance and transpiration was measured on mature umbels (the major evaporating surface) of papyrus (Cyperus papyrus L.) growing in a fringing swamp on Lake Naivasha, Kenya.Umbel water potential declined only slightly during the morning but fell rapidly after midday to a minimum value of-1.5 M Pa in ...

Cyperus papyrus in Lake Victoria: Genetic Information, Utilisation and Resource Sustainability
JOURNAL OF THE GEOGRAPHICAL ASSOCIATION OF TANZANIA, 2021Many wetlands in the Lake Victoria basin are dominated by Cyperus papyrus, which are very productive and, therefore, have an important role both ecologically and socially. The increasing harvesting pressure of papyrus threatens its future. Thus, a conservation approach was employed to determine the intensity of the pressure and threat to the papyrus ...
