Comparative performance of invasive alien Eichhornia crassipes and native Ludwigia stolonifera under non-limiting nutrient conditions in Lake Naivasha, Kenya
(Hydrobiologia, 2010-09)The ability of Ludwigia stolonifera to thrive in the presence of Eichhornia crassipes was investigated in Lake Naivasha, Kenya. L. stolonifera (indigenous) and E. crassipes (invasive alien) were grown in outdoor experimental ... -
Zooplankton partitioning in a tropical alkaline-saline endorheic Lake Nakuru, Kenya: Spatial and temporal trends in relation to the environment
(Lakes & Reservoirs: Research and management, 2011)Spatial and temporal zooplankton variations were studied for 1 year in tropical alkaline–saline Lake Nakuru to determine how they partition in the habitat, relative to environmental variables. Monthly samples were collected ... -
290IMPACTS OF COMMUNITY ACTIVITIES ON ENVIRONMENTAL RESOURCES: THE POTENTIAL FOR DEVELOPING PAYMENT SCHEMES FOR ENVIRONMENTAL SERVICES
(VDM Dr Muller Gmbh and co, 2011-01)Natural resources have continued to be degraded largely because of lack of well-defined property rights, population pressure, high levels of poverty and the lack of proper understanding of deleterious impacts of human ... -
Financing provision of environmental services in Mt. Elgon region for the protection of watersheds
(VDM Dr Muller Gmbh and co, 2011-01)This study examined direct payments for environmental services (PES) as a program for supporting the conservation of forest resources and services where environmental conservation is financed on the basis ... -
Competition between Lemna minuta and Lemna minor at different nutrient concentrations
(Plant Biology and Nature Management (APNA) Elsevier, 2011-02)We investigated the differential responses of invasive alien Lemna minuta and native Lemna minor to nutrient loading as well as the mechanism of competition between the species. The role of nutrients, species identity, ... -
Competitive abilities of invasive Lagarosiphon major and native Ceratophyllum demersum in monocultures and mixed cultures in relation to experimental sediment dredging
(Aquatic Botany, 2011-06)Competitive abilities of Lagarosiphon major (Ridley) Moss (invasive in Belgium) and native Ceratophyllum demersum L. were assessed experimentally in relation to sediment dredging. We mimicked these conditions by taking ... -
Dryland Farming and Food Security in Kenya: Challenges and Research Priorities
(Elixir, 2011-06)Agriculture is the backbone of Kenya and employs the highest proportion of the population, accounts for approximately a quarter of the country’s Gross Domestic Product (GDP) and close to two-thirds of total exports, hence ... -
Seed dispersal by Tana River mangabeys in fragmented gallery forests

Haematological Response of Rastrineobola argentea Exposed To Subchronic Doses of Inorganic Cadmium (Cd), Methylmercury and Polychlorinated Biphenyl (PCB) via Dietary Exposure Pathway
(International Journal of Science and Research (IJSR), 2012)Haematological indices provide information on various aspects of fish health when exposed to environmental contaminants. We evaluated the effects of cadmium, methyl mercury (MeHg), and Polychlorinated Biphenyl (PCB) on the ... -
Dynamic of Stress Response in Victoria Labeo (Labeo victorianus) during transfer from the Hatchery to cages and Ponds under Differential Caged Stocking Densities
(International Journal of Science and Research (IJSR), 2012)Variation in fish stocking densities translate to difference in growth performance, yields and economic benefits in fish culture. Transferring fish directly from hatcheries to the cages or ponds may induce stress. We ... -
Faecal Bacterial and Parasitic Contamination of Drinking Water in Eldoret Municipality, Kenya
(2012)Faecal contamination of water can introduce a variety of pathogens into water ways, including bacteria, viruses, protozoans and parasitic worms. Poor excreta disposal is often associated with lack of adequate water supplies, ... -
Prevalence of intestinal parasitic infections in certified food-handlers working in food establishments in the City of Nairobi, Kenya
(Journal of Biomedical Research, 2012-03)Most intestinal parasites are cosmopolitan with the highest prevalence in the tropics and subtopics. Rural-to-urban migration rapidly increases the number of food eating places in towns and their environs. Some of these ... -
POPULATION ECOLOGY, DIET AND MOVEMENT OF STRAW-COLOURED FRUIT BATS (Eidolon helvum), WESTERN KENYA
(research gate, 2012-07)The population status, movement, roost-site selection and diet of straw-coloured fruit bats (Eidolon helvum) were studied over a seven-month period in western Kenya. Overall, the bat population fluctuated markedly from as ... -
The challenges of wild game on forest plantations management objectives in forest ecosystems in kenya
(Emerging Academy Resources, 2013)Forests in Africa and Asia host various wildlife populations that cause varying levels of damages to forest resources. The economic damage is more severe in forest plantations meant for timber production that require huge ... -
