In vivo antimalarial and acute toxicity properties of hexane and chloroform extracts from Clausena anisata (Willd.) Benth
(2012)Background: Drugs are an important tool for control of malaria. However, drug resistance is likely to compromise available antimalarial drugs with time. As a result, efforts are being directed towards discovery and development ... -
Incidence of Brucella infection in various livestock species raised under the pastoral production system in Isiolo County, Kenya
(BMC, 2021-10)Background: We implemented a longitudinal study to determine the incidence of Brucella infection in cattle, camels, sheep and goats that were being raised in a pastoral area in Isiolo County, Kenya. An initial cross-sectional ... -

The influence of diel climatic cycle on the depth time distribution of phytoplankton and photosynthesis in a shallow equatorial lake (Lake Baringo), Kenya.
(Springer, 1995-05)Lake Baringo is a shallow equatorial lake. This paper reports a diel study of the depth-time distribution of phytoplankton and photosynthesis at one location in Lake Baringo on 10 March 1989. The water column shows a pattern ... -
Influence of drought on interactions between Rhopalosiphum padi and ground dwelling predators – A mesocosm study
(Wiley, 2021-05)Climate change will lead to extreme droughts, but it is difficult to predict how this will affect crop pests. In particular, it is unclear how interactions between natural en- emies and pests will be influenced. In the ... -
Influence of large woody debris accumulations on macro invertebrate distribution in a low order forested tropical stream, Sagana river, Kenya
(Jomo Kenyatta University of Agriculture and Technology, 2014)Woody debris accumulations are important ecological components in low order forested streams. They provide forage and refuge for a macroinvertebrates, which are key trophic components for riverine fish. The occurrence ... -
INFLUENCE OF LARGE WOODY DEBRIS ACCUMULATIONS ON MACROINVERTEBRATE DISTRIBUTION IN A LOW ORDER FORESTED TROPICAL STREAM, SAGANA RIVER, KENYA
(Jomo Kenyatta University of Agriculture and Technology, 2014)Woody debris accumulations are important ecological components in low order forested streams. They provide forage and refuge for a macroinvertebrates, which are key trophic components for riverine fish. The occurrence ... -
Interaction of Fusarium oxysporum f.sp.vasinfectum and the fungal feeding nematode Aphelechus avenae on Bt cotton
(2014)The fungal feeding nematode Aphelenchus avenae (APH) feeds on different species of fungi including Fusarium oxysporum f. sp. vasinfectum (FOV) that causes wilt in cotton. The objective of this study was to assess the ... -
International Journal of Environment and Climate Change
(2020-12-21)Africa is under pressure from climate stresses and is highly vulnerable to the impacts of climate change. In Kenya, agriculture is the backbone of the economy making it an important contributor to food security of rural ... -
Is leaf pubescence of Cape Proteaceae a xeromorphic or radiation-protective trait?
(CSIRO Publishing, 2012-03)Although pubescence has traditionally been considered to be related to the water economy of plants, the results are ambivalent and vary between different species. We tested two contrasting hypotheses for the functional ... -
Isolation and characterisation of bacteria from the haloalkaline Lake Elmenteita, Kenya
(Springer, 2010-04)Culture-independent studies show that soda lake environments harbour diverse groups of bacteria and archaea. In this study different enrichment and isolation media were used in an attempt to isolate novel groups of bacteria ... -
Isolation and characterization of actinobacteria from Lake Magadi, Kenya
(Academic Journals, 2013-08-09)Actinobacteria are ubiquitous and have been detected in terrestrial and aquatic ecosystems. Although, various studies have focused on the ecology of this phylum, data on the ecology of actinobacteria endemic to soda lakes ... -
