The impacts of introduced species on lake ecosystems: A case of Lakes Victoria and Naivasha, Kenya.
(2019)
Fish and other aquatic organisms have been introduced into new environments for various reasons. Provision of sports fishery, supplemental to stocks, to fill empty niches, control weeds, and disease vectors and even create ...
Carbon dioxide exchange and biomass productivity of the herbaceous layer of a managed tropical humid savanna ecosystem in western Kenya
(Oxford University Press, 2013-08-01)
Aims
Humid savannas, as a result of high precipitation amounts, are highly productive. They are also hotspots for land use change and potential sources of carbon dioxide (CO2) due to the large soil carbon (C) stocks. ...
Genetic diversity and eco-geographical distribution of Eleusine species collected from Ethiopia.
(African Journals OnLine (AJOL), 2014-02-21)
Eleusine is a small grass genus with three basic chromosome numbers (x=8, 9 and 10) and comprises of eight species including E. coracana subsp. coracana, (finger millet), which is an important subsistence crop in Africa ...
Physiological and biochemical responses of five nerica rice varieties (Oryza sativa L.) to water deficit at vegetative and reproductive stage
(2012)
Food shortage is a major problem in sub Saharan Africa as population
increases. Over 89% of Kenyans are food poor and are malnourished especially in rural
areas. NERICA (New Rice for Africa) are high yielding rainfed ...
UGbS-Flex, a novel bioinformatics pipeline for imputation-free SNP discovery in polyploids without a reference genome: finger millet as a case study
(BioMed Central, 2018-12-01)
Research on orphan crops is often hindered by a lack of genomic resources. With the advent of affordable sequencing technologies, genotyping an entire genome or, for large-genome species, a representative fraction of the ...
Responses of ecosystem carbon dioxide fluxes to soil moisture fluctuations in a moist Kenyan savanna
(Cambridge University Press, 2010-11-01)
Measurements were conducted within a fence-exclosure between February 2008 and July 2009 to investigate the influence of soil moisture on ecosystem CO₂ fluxes in a Themeda triandra-dominated grassland of a humid Kenyan ...
Mechanistic understanding of iron toxicity tolerance in contrasting rice varieties from Africa: 1. Morpho-physiological and biochemical responses
(CSIRO PUBLISHING, 2019-01-21)
Iron (Fe) is a fundamental element involved in various plant metabolic processes. However, when Fe uptake is excessive, it becomes toxic to the plant and disrupts cellular homeostasis. The aim of this study was to determine ...
Integrated management of Striga hermonthica, stemborers, and declining soil fertility in western Kenya
(Elsevier, 2008-05-10)
Striga hermonthica (Delile) Benth., stemborers, and declining soil fertility are serious threats to sustainable food production in the Lake Victoria zone of Kenya. To address these constraints, promising integrated crop ...
Growth changes of seven Amaranthus (spp) during the vegetative and reproductive stages of development as influenced by variations in soil water deficit
(2015)
Soil water deficit is a principal a biotic factor that limits plant growth and
development in dry areas. Insufficient moisture contributes to soil water deficit and some
negative effects on Amaranthus (spp) such as ...
Assessment of four commercial watermelon cultivars and one local landrace for their response to naturally occurring diseases pests and non-pathogenic disorders in sub-humid …
(Asian Research Publishing Network (ARPN), 2008)
Four commercial watermelon cultivars available in Kenya and one local landrace were evaluated for their susceptibility/resistance to naturally occurring diseases, pests and non-pathogenic disorders. The accessions included ...
