(2021-03)Paenibacillus larvae is a spore-forming bacterium causing American foulbrood (AFB) in honey bee larvae. The remains of a diseased larva contains billions of extremely resilient P. larvae spores viable for decades. Burning ... -
Phenomic characterization of Crotalaria germplasm for crop improvement
(Cabi, 2021-03)Background: Diversifcation of global food systems through exploration of traditional varieties and wild edible plant species is a focal mitigation strategy for food security worldwide. The present study determined the ... -
Phenotypic Diversity of Doum Palm (Hyphaene compressa), a Semi-Domesticated Palm in the Arid and Semi-Arid Regions of Kenya
(Hindawi, 2020-12-29)Hyphaene compressa is an economically important palm in Africa. Despite its significant role in the livelihoods of rural communities, the diversity of doum palm is poorly documented and studied. In addition, it has no ... -
Isolation and Characterization of Bacteria from Lakes Olbolosat and Oloiden, Kenya
(Academic journals, 2020)There is still unexplored reservoir of microorganisms from sediments and water within Lakes Olbolosat and Oloiden using culture dependent technique. The current study compares bacterial diversity within Lake Olbolosat a ... -
The Contribution of Occult Precipitation to Nutrient Deposition on the West Coast of South Africa
(2015-05-27)The Strandveld mediterranean-ecosystem of the west coast of South Africa supports floristically diverse vegetation growing on mostly nutrient-poor aeolian sands and extending from the Atlantic Ocean tens of kilometers ... -
SPEI-based spatial and temporal evaluation of drought in Somalia
(Elsevier, 2020-09-06)Somalia is one of the most drought prone countries both in Africa and globally. Drought events usually develop gradually unnoticed, causing tremendous effects on both agriculture and environment. This study evaluated ... -
Temporal variation in physico-chemical characteristics, phytoplankton composition and biomass in Lake Solai, Kenya
(2019-10-20)The physico-chemical properties and phytoplankton community structure of Lake Solai were investigated between April 2018 and August 2018. Water temperature, conductivity (EC), dissolved oxygen (DO) content and pH were ... -
Low foristic richness of afro‐alpine vegetation of Mount Kenya is related to its small area
(Springer, 2019-10-29)Diversity patterns of tropical alpine vegetation is poorly studied. We estimated vascular plant floristic richness for two typical afro-alpine communities in Mount Kenya using a series of nested plots sized from 25 to 100 ... -
Response of Selected Kenyan Rice Cultivars to Infection by Root Knot Nematode (Meloidogyne incognita)
(Springer, 2019-03-22)Meloidogyne incognita causes huge yield losses in rice which is the third most important cereal crop in Kenya. The aim of this study was to identify M. incognita-resistant rice cultivars from Kenya and relate the responses ... -
In vitro anti-cancer efficacy and phyto-chemical screening of solvent extracts of Kigelia africana (Lam.) Benth
(Cell press, 2021-01-25)Background and objectives: Kigelia africana is a medicinal plant growing naturally in many parts of Africa. In Kenya, a water concoction of the plant is used to treat breast and prostate cancers. Laboratory data on its ... -
