Growth response of woody species to elephant foraging in Mwea National Reserve, Kenya
(University of Nairobi, 2009-12)
The African elephant (Loxodonta africana) is known to greatly affect the structure and dynamics of vegetation. In Mwea National Reserve, elephants foraged mainly on Acacia ataxacantha and Grewia bicolor out of the five ...
NPP Grassland: Nairobi, Kenya, 1984-1994
(University Of Nairobi, 1996)
Net primary production of a savanna grassland in Nairobi National Park, Kenya, was determined from 1984 to 1994 by monitoring monthly dynamics of live biomass and dead matter, above and below ground, together with monthly ...
Toward a holistic and risk-based management of european river basins
(University of Nairobi, 2009)
The European Union Water Framework Directive (WFD) requires a good chemical and ecological status of European surface waters by 2015. Integrated, risk-based management of river basins is presumed to be an appropriate ...
Soil nutrient content, soil moisture and yield of Katumani maize in a semi-arid area of Kenya
(2007)
Many farmers in Kenya’s semi arid lands cannot afford to purchase inorganic fertilisers to improve their
crop yields. They thus rely on traditional agronomic practices such as addition of crop residues, animal
manures ...
Factors affecting abundance and distribution of submerged and floating macrophytes in Lake Naivasha, Kenya
(2007)
Macrophytes have been shown to perform important ecological roles in Lake Naivasha. Consequently, various studies regarding the impact of biotic factors on the macrophytes have been advanced but related studies on environmental ...
Vegetation dynamics of coastal sand dunes near Malindi, Kenya
(University of Nairobi, 2001-06)
This study describes the composition, structure and distribution of coastal dune vegetation near Malindi, Kenya. The vegetation was made up of 156 plant species. Sixty families were recorded with Gramineae (seventeen ...
Observations and modeling of biomass and soil organic matter dynamics for the grassland biome worldwide
(University of Nairobi, 1993-12)
Century is a model of terrestrial biogeochemistry based on relationships between climate, human management (fire, grazing), soil properties, plant productivity, and decomposition. The grassland version of the Century model ...
Assessment of the performance of exotic and indigenous tree and shrub species for rehabilitating saline soils of Northern Kenya
(University of Nairobi, 2003)
In the semi-desert zone of North Horr, northern Kenya, soil salinity reaches toxic levels, with extensive salt crusts at the surface. Environmental groups are involved in tree and shrub planting trials with the objective ...
Growth characteristics of two tropical forest species Warburgia ugandensis and Polyscias fulva seedlings grown under contrasting light conditions
(University Of Nairobi, 2008)
Growth parameters for seedlings of two forest trees, Warburgia ugandensis and Polyscias fulva, were
measured under various light growth conditions. Leaf area and plant height were significantly higher
under low light (< ...
δ13 Values of the Centrospermeae Species and Their Ecological Implications in the Semi Arid Conditions
