Influence of varying light regimes on photosynthesis and related variables on tree seedlings of Warburgia ugandensis Sprague and Polyscias fulva (Hiern) harms

  The physiology of seedlings of Warburgia ugandensis and Polyscias fulva were studied at varying light levels. Photosynthesis was significantly higher in P. fulva(1.4 mmols CO2 m-2 s-1) than in W. ugandensis (0.3 mmols CO2 m-2s-1) when grown in full sunlight. However, photosynthesis was not significantly (P > 0.05) different under moderate and...

The current pollution status of the new Calabar river in the Niger Delta region of Southern Nigeria: A survey of antibiogram profiles of its bacterial isolates

  The incidence of environmental pollutants on bacterial strains isolated from the New Calabar River in the Niger Delta region of Southern Nigeria were investigated in order to ascertain the possible effects on antibiotic resistance and patterns. The physico-chemical parameters of the water samples assayed included temperature, pH, biochemical oxygen demand, chemical oxygen demand, dissolved oxygen, salinity,...

Soil carbon and nutrient accumulation under forest plantations in southern Rwanda

  Tree and soil interactions may result in changes in soil carbon and nutrient contents. Forest plantations made up of monodominant stands of 17 different species, some native and some exotic to Rwanda, as well as a stand with mixed native tree species were investigated. Biosequential sampling was used followed by basic soil chemical analyses. Results revealed that the plantation species composition influenced...
