(2014-10)BACKGROUND: Development of “combination” assays detecting in parallel, within a single test, Hepatitis C Virus (HCV) antigens and antibodies, not only reduces the window period in HCV-infection but also costs. Reduction ... -
Evaluation of beverage quality and green bean physical characteristics of selected Arabica coffee genotypes in Kenya
(Academic Journals, 2009-10)Physical characteristics of green coffee bean have been reported to affect beverage quality to some extent. The objective of this study was to assess the beverage quality and green bean physical characteristics of forty ... -
Evaluation of prokaryotic diversity of five hot springs in Eritrea
(BioMed Central, 2017-09)Background: Total community rDNA was used to determine the diversity of bacteria and archaea from water, wet sediment and microbial mats samples of hot springs in the Eastern lowlands of Eritrea. The temperatures of ... -
Expression of metallothionein and tubulin in heavy metal-tolerant Anopheles gambiae sensu stricto (Diptera:Culicidae).
(Elsevier, 2010)Anopheles mosquitoes have been shown to adapt to heavy metals in their natural habitats. In this study we explored the possibility of using Anopheles gambiae sensu stricto as bioreporters for environmental heavy metal ... -
Field Abundance Patterns and Odor-Mediated Host Choice by Clover Seed Weevils, Apion fulvipes and Apion trifolii (Coleoptera: Apionidae)
(2015-02)The clover seed weevils Apion fulvipes Geoffroy, 1785 and Apion trifolii L., 1768 (Coleoptera: Apionidae) cause major losses to seed production of white clover (Trifolium repens L.) and red clover (Trifolium pratense ... -

Field Screening of Selected Coffea arabica L. Genotypes Against Coffee Leaf Rust
(2012-06)Coffee Leaf Rust (CLR) is a fungal disease caused by Hemileia vastatrix Berk et Br. and is one of the major diseases of coffee. It causes premature leaf fall, yield loss and even death of the tree in severe cases. Coffee ... -
Fish Species Composition and Diversity of Small Riverine Ecosystems in the Lake Victoria Basin, Kenya
(2012-09)Riverine ecosystems in the Lake Victoria Basin (LVB) significantly contribute to the lake’s water budget and aquatic biodiversity. Despite their significance to the lakes fisheries, only limited biodiversity studies have ... -

Fluctuating algal food populations and the occurrence of lesser flamingos (Phoeniconaias minor) in three Kenyan rift valley lakes
(2010-06)The last two decades have witnessed increasing episodes of lesser flamingo die-offs in East Africa. Based on data on phytoplankton composition, biomass, and flamingo population density in three alkaline-saline lakes ... -
Food algae for Lesser Flamingos: a stocktaking
(Springer, 2016-07)Lesser Flamingo, the flagship species of saline wetlands of Africa and India, is a specialised feeder subsisting on microscopic cyanobacteria and algae. To establish the relationship between flamingo occurrence and food ... -
Food web structure of nematode communities in irrigated rice fields
(Heliyon, 2023-02)Nematodes are a key component of the soil food web and they play an important role in the provision of ecosystem services. Rice cultivation in Mwea, Kenya involves the intensive use of fertilizers and pesticides which ... -
Free-living nematode assemblages associated with maize residues and their ecological significance
