Louisiana crayfish (Procambarus clarkii) (Crustacea: Cambaridae) in Kenyan ponds: non-target effects of a potential biological control agent for schistosomiasis
(Taylor & Francis, 2010)The Louisiana crayfish (Procambarus clarkii) has been proposed as a biological control agent for the intermediate snail hosts (Bulinus and Biomphalaria spp.) of human schistosomes (Schistosoma haematobium and S. mansoni) ... -

12,13-Deoxytrichoverrins from Myrothecium verrucaria
(Department of Chemistry, 1989-05)The structures of two new diastereoisomeric 12,13-deoxytrichothecenes have been established by a combination of nmr and mass spectroscopy. -
Factors influencing drift transport and concentration in a second-order high altitude tropical river in central Keny
(Wiley, 1994)The factors that influence drift transport and concentration in the Naro Moru River are recapitulated. The most important variables accounting for the highest proportions of drift transport variance are volume sampled by ... -
Growth patterns of the pearl oyster Pinctada margaritifera L. in Gazi Bay, Kenya Growth patterns of the pearl oyster Pinctada margaritifera L. in Gazi Bay, Keny
(Taylor & Francis, 2005)Culture of pearl oysters is rapidly increasing worldwide, including the western Indian Ocean. The oyster Pinctada margaritifera L., which produces the most highly valued black pearls, occurs in East Africa, a nd as been ... -

(Department of Chemistry, 1981) -
Trophic Ecology of Some Common Juvenile Fish Species in Mtwapa Creek, Kenya
(AJOL, 2004)The trophic status of common fish species in Mtwapa creek on the Kenyan coast was studied. Both the qualitative and quantitative spectra of the diets of these fish species were investigated. It was found that the eight ... -
Diel vertical distribution of zooplankton in Lake Naivasha, Kenya
(SpringerDepartment of Zoology, University of Nairobi, 1992)Diurnal and diel vertical distribution of limnetic zooplankton species in relation to temperature and dissolved oxygen profiles was examined at a central station in Lake Naivasha. During calm days thermal stratification ... -
Verrucarin L, a new macrocyclic trichothecene
(Department of Chemistry, 1981-01) -
Durations of development and production estimates by two crustacean zooplankton species Thermocyclops oblongatus Sars (Copepoda) and Diaphanosoma excisum Sars (Cladocera), in Lake Naivasha, Kenya
(SpringerDepartment of Zoology, University of Nairobi, 1994)Durations of embryonic and post-embryonic development of the two dominant zooplankton crustaceans Thermocyclops oblongatus (Copepoda) and Diaphanosoma excisum in Lake Naivasha were determined at various lake water temperatures ... -
Ecology and role of zooplankton in the fishery of Lake Naivasha
(SpringerDepartment of Zoology, University of Nairobi, 1990)Taxonomic composition, distribution, community structure and seasonality of Lake Naivasha zooplankton between 1978 and 1980 are described. The ecological status of the zooplankton in relation to prevailing ecological factors ... -

Phosphorus inputs to Lake Naivasha, Kenya, from its catchment and the trophic state of the lake
(SpringerDepartment of Zoology, University of Nairobi, 2002)The main river supplying Lake Naivasha, Kenya, the Malewa, drains a catchment given over to largely subsistence cultivation and animal husbandry. The lake itself is the focus for an intensive horticultural industry based ... -

Science and Management of Transboundary Lakes: Lessons Learned from the Global Environment Facility Program
(University of Nairobi.Department of Geology, University of Nairobi, Nairobi, Kenya, 2013)The International Waters Science Project Lakes Working Group reviewed 58 Global Environment Facility (GEF) projects that addressed serious environmental and human development issues in transboundary lakes. The lessons ... -
Holocene palaeohydrology, groundwater and climate change in the lake basins of the Central Kenya Rift
(Taylor & FrancisDepartment of Geology, University of NairobiSchool of Physical Sciences, 2009)The Central Kenya Rift contains small soda lakes such as Nakuru, Elmenteita and Bogoria, freshwater Lake Naivasha, and the partly (spatially) freshwater Lake Baringo. The hydrology of this area is controlled mainly by ... -
The Mystery of Trichothecene Antibiotics in Baccharis Species
(Department of Chemistry, 1988-08)The Brazilian higher plant Baccharis coridifolia has been shown to synthesize de novo a series of highly toxic macrocyclic trichothecene antibiotics heretofore found to be produced only by fungi. These compounds are produced ... -
Larvicidal benzoquinone from Embelia schimperi
(Department of Chemistry, 2004)Chromatographic analysis of air-dried berries of Embelia schimperi led to the isolation of methyl vilangin (1), which was characterized on the basis of physical and spectroscopic data. The compound was found to be lethal ... -
