Abstract:
Entandrophragma angolense is relatively slow growing species and its growth needs to be enhanced by soil nutrients amendment. Uniformed two weeks old seedlings of E. angolense were transplanted into the polythene pots filled with 2kg of degraded soil and mixed with different levels of biochar and ash produced from bamboo. A 2 x 7 factorial experiment was laid out in Completely Randomized Design (CRD) with four replications to assess the effects of charred bamboo and its ash on the stem girth, leaf area, leaf production and shoot height of E. angolense. The germination data were subjected to de

Abstract:
Relative densities of mahogany species vary across tropical Africa and correspond with changes in soil fertility and moisture status. Seedling growth of four co-occurring African mahoganies (Entandrophragma spp.) was studied in relation to soil nutrient and moisture status in a shade-house experiment. On naturally occurring forest soils, E. cylindricum and E. utile exhibited increased relative growth rate (RGR) and decreased root mass ratio (RMR) with an increase in soil fertility while E. angolense and E. candollei did not. Changes in leaf morphology with fertility did not correspond to chang

Heavy metals concentrations were determined in the crab (Sesarma angolense) and sediment of Benin River, Niger Delta Region, Southern Nigeria using Atomic Absorption Spectrometer. Except for Cd and Ni, other heavy metal concentrations differed insignificantly (p>0.05) among the stations. Thus Cd and Ni are the principal elements responsible for spatial variability in terms of heavy metal concentration in the sediment. Mean values of the heavy metals Fe, Zn, Mn, Cu, Cd, V, Cr, Pb and Ni in sediment from the three stations were 2.23, 0.39, 0.07, 0.08, 0.02, 0.04, 0.03, 0.06 and 0.12 respectiv

Abstract:
The phytochemical investigation and evaluation of the antioxidant activity of the leaves, bark, and roots of Cochlospermum angolense Welw ex Oliv—a valued plant that is widely used in traditional Angolan medicine—hold significant importance. Compounds were extracted from the aforementioned plant using acetone and ethanol and identified by HPLC-ESI-MSn. Both extracts demonstrated notable abilities to scavenge 2,2-diphenyl-1-picrylhydrazyl, nitric oxide, and superoxide radicals, as well as to inhibit lipid peroxidation.

Tree development goes through a prolonged suffrutex stage to reach the sapling stage and then, finally, the bole tree stage. This study focused on assessing the main factors facilitating the development of Pterocarpus angolensis seedlings through the suffrutex stage to the sapling stage in Namibia dry forests.
