Biological diversity of the Yala Swamp lakes, with special emphasis on fish species composition, in relation to changes in the Lake Victoria Basin (Kenya): threats and conservation measures
(Biodiversity & Conservation, 2003-05)During the second half of the last century, the Lake Victoria ecosystem has undergone drastic ecological changes. Most notable has been the decline in the populations of many endemic cichlid fishes. The lake has lost nearly ... -
Biomass Energy Resource of the Highland Bamboo (Yushania alpina) and Its Potential for Sustainable Exploitation in Southern Aberdares Forest
(Scientific Research Publishing, 2017-08)Yushania alpina is the only bamboo species native to Kenya and covers about 150,000 ha growing in pure or mixed stands in the montane forests. The Aberdare forest is one of the natural habitats for Y. alpine occupying an ... -
Combined effects of photoperiod and temperature on growth and survival of African catfish (Clarias gariepinus, Burchell 1822) larvae under laboratory conditions
(Taylor and Francis, 2016)The effect of photoperiod (24L:00D, 12L:12D, and 00L:24D) and temperature (22 ± 1°C and 28 ± 1°C) on performance of Clarias gariepinus larvae was tested. Larvae weighing 3.2 ± 0.24 mg were cultured in aquaria at a stocking ... -
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 ... -
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 ... -
Diversity and Altitudinal Distribution of Understorey Corticolous Lichens in a Tropical Montane Forest in Kenya (East Africa)
(research gate, 2018)Lichens constitute an important component of tropical forest biodiversity. This study inventoried corticolous lichens and examined their variation in various forest types with varying climatic conditions in Mt. Kenya, East ... -
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 ... -

(Lakes & Reservoirs: Research & Management, 2006-12)Lake Baringo is a shallow, internal drainage, freshwater lake located in the Kenyan Rift Valley. The lake is an important source of water for humans and livestock, as well as a significant income source for local communities ... -
Metazoan Parasites of Some Commercially Important Fish along the Kenyan Coast
(WIOMSA, 2004)The parasitic fauna of some commercial fish species along the Kenyan coast was investigated at four localities between August 2001 and March 2002. The study was carried out to establish the extent of parasitisation of ... -
Pre-Disposing Factors Contributing to the Prevalence of Intestinal Parasitic Infections (IPI) among the HIV/AIDS Patients in Bungoma County, Kenya
(International Journal of Science and Research (IJSR), 2014-12)The role of HIV infection on the pathognomomic of HIV infections is not clearly understood. The aim of the current study was to determine the epidemiology of IPI and predisposing factors among HIV/AIDS patients in Bungoma ... -
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 ... -
