Effect of biotic and abiotic factors on composition and foraging intensity of subterranean termites
Elucidating the influence of ecological factors on composition and foraging intensity of subterranean termites is critical in development of sustainable termite management strategies. Our aim was therefore to analyze the effect of selected biotic and abiotic factors on composition and foraging intensity of termites. We used principal component and canonical correspondence analysis to select appropriate...

Water quality changes due to abattoir effluent: A case on Mchesa Stream in Blantyre, Malawi
Abattoir effluent is known to degrade the quality of receiving water bodies. This study assesses the impact of effluent from Shire Valley Abattoir on the physico-chemical parameters of Mchesa Stream in Blantyre. Water samples were collected from five sampling sites along Mchesa Stream located at progressive distances from the discharge point. Sampling was done three times over a period of four months (June to...

Growth and yield potential of Echinochloa pyramidalis (Lam.) Hitchc & Chase: A forage plant used in vertical-flow constructed wetlands in Cameroon
This work aims at assessing growth and productivity of Echinochloa pyramidalis in the saline and saline-flooded processes of wetland treatment. Growth characteristics such as density, number of dead plants, height and number of new shoots and biomass production of the plant were studied using 24 laboratory-scale units of vertical-flow constructed wetlands fed with faecal sludge supernatant. Plants...
