Biodiversity characteristics of small high-altitude tropical man-made reservoirs in the Eastern Rift Valley, Kenya
(University Of Nairobi, 2002)
The biodiversity characteristics in eight small (0.065–0.249 km2) public man-made reservoirs in the central part of the Eastern Rift Valley, Kenya, were studied between 1995 and 1998. A total of 71 phytoplankton species ...
A Synoptic Ecopath model of biomass flows during two different static ecological situations in Lake Nakuru (Kenya)
(Department of Zoology, University of Nairobi, 2001)
Trophic relationships inside the Lake Nakuru ecosystem during two different phases are described by using the ECOPATH model. This allows a partial explanation of the ecological changes observed in the lake and to show that ...
Bathymetry of Lake Bogoria, Kenya
(Nature Kenya/East African Natural History Society, 2003)
This paper presents the first bathymetric map for the approximately 17 km by 2 km alkaline Lake Bogoria situated in the eastern Rift Valley of Kenya. Longitudinal and transverse cross sections of the lake are also provided. ...
Comparing macrophyte herbivory by introduced Louisiana crayfish (Procambarus clarkii) (Crustacea: Cambaridae) and native Dytiscid beetles (Cybister tripunctatus) (Coleoptera: Dytiscidae), in Kenya
(2005)
The omnivorous Louisiana crayfish, Procambarus clarkii, has caused significant changes to macrophyte communities worldwide and may have similar negative effects in Kenya if used as a biological control agent for snails ...
Chemical Characteristics, with particular reference to phosphorus, of the rivers draining into Lake Naivasha, Kenya
(School of Biological Sciences, 2002)
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 ...
Exploring the trophic structure in organically fertilized and feed-driven tilapia culture environments using multivariate analyses
(AquacultureResearch, 2006)
Reports of similar yields in manure and feed-driven tilapia culture environments raise questions on food utilization in these environments. The possibility that similar production rates are because of utilization of di¡erent ...
Dissipation Behavior of Malathion and DimethoateResidues from the Soil and Their Uptake by Garden Pea(Pisum sativum)
(Environmemental Contamination and Toxicology, 2000)
The contamination of soil by pesticide chemicals can occur through direct application to control some inhabiting insect pests of a variety of economic plants while indirect avenues can occur through aerial ...
THE MAJOR ENVIRONMENTAL FACTORS THAT INFLUENCE RAPID DISAPPEARANCE OF PESTICIDES FROM TROPICAL SOILS IN KENYA
(Toxicological & Environmental Chemistry, 2001)
Results of field and laboratory studies on adsorption/desorption, leaching, dissipation, bound residue formation and metabolism of DDT, DDE, lindane, parathion, malathion, dimethoate and carbofuran in tropical soils in ...
Conditional scale function estimate in the presence of unknown conditional quantile function
(African Network of Scientific and Technical Institutions (ANSTI), 2005)
Standard approach for modeling and understanding the variability of statistical data or, generally, dependant data, is often based on the mean variance regression models. However, the assumptions employed on standardized ...
Intensification of Agriculture as the Driving Force in the Degradation of Nzoia River Basin: the Challenges of Watershed Management
(2007)
The Lake Victoria riparian countries suffer from devastating effects of floods and droughts
occasioned by severe weather related natural phenomena. The floods often follow prolonged
droughts that have become a mark of ...
