The East African rift system in the light of KRISP 90
(Department of Geology, University of Nairobi, 1994)On the basis of a test experiment in 1985 (KRISP 85) an integrated seismic-refraction/teleseismic survey (KRISP 90) was undertaken to study the deep structure beneath the Kenya rift down to depths of 100–150 km. This paper ... -

Eave Screening and Push-Pull Tactics to Reduce House Entry by Vectors of Malaria
(2016)Long-lasting insecticidal nets and indoor residual spraying have contributed to a decline in malaria over the last decade, but progress is threatened by the development of physiological and behavioral resistance of mosquitoes ... -
Ecdysteroids as regulators of host and parasite interactions: a study of interrelationships between Schistosoma mansoni and the host snail, Biomphalaria glabrata.
(1991)Ecdysteroids have been detected in trematode parasites and in several species of gastropod snails. The potential role of these and other hormones as regulators of host/parasite interactions is discussed. This study considers ... -

Ecological aspects of Eriophyes ficus Cotté and its mite Phytoseius finitimus Ribaga in fig orchards.
(University of NairobiSchool of Biological and Physical Sciences, 1990)A survey in 1984-86 found that Eriophyes ficus [Aceria ficus] was the main pest on the fig varieties Sultani and Adsi in Egyptian orchards. The main peaks of infestation were in June and October on young leaves of both ... -
Ecological distribution of East African Culicoides Latreille (Dipt., Ceratopogonidae) as shown by light-traps
(Department of Zoology, University of Nairobi, 1971)Sixty-one Culicoides spp. were collected in Kenya, Uganda and Tanzania between January 1966 and December 1967 using light-traps at 35 stations on a NW-SE transect from the Indian Ocean to central Uganda to evaluate the ... -

Ecological niche modelling of Rift Valley fever virus vectors in Baringo, Kenya.
(University of Nairobi, 2017)BACKGROUND: Rift Valley fever (RVF) is a vector-borne zoonotic disease that has an impact on human health and animal productivity. Here, we explore the use of vector presence modelling to predict the distribution of RVF ... -
The ecological state of Lake Naivasha, Kenya, 2005: Turning 25 years research into an effective Ramsar monitoring programme
(Department of Zoology, University of Nairobi, KenyaDepartment of Biology University of Leicester, England, 2006)The present paper summarises the state of ecological knowledge in the lake based upon the research of the teams of Harper & Mavuti, funded by the Earthwatch Institute since 1987. It suggests how the research knowledge ... -
Ecological, recreational and educational potential of a small artificial wetland in an urban environment
(University of Nairobi, 2019)Pertinent questions remain on whether small, artificial wetlands, such as abandoned quarries play any ecological or socio-economic role in the environment. To increase information on roles played by small-sized artificial ... -
Ecologists can enable communities to implement malaria vector control in Africa
(Department of Zoology, 2006)Integrated vector management (IVM) for malaria control requires ecological skills that are very scarce and rarely applied in Africa today. Partnerships between communities and academic ecologists can address this capacity ... -
Ecology and Behavior of Anopheles arabiensis in Relation to Agricultural Practices in Central Kenya
(University of Nairobi, 2013)Ecological changes associated with anthropogenic ecosystem disturbances can influence human risk of exposure to malaria and other vector-borne infectious diseases. This study in Mwea, Kenya, investigated the pattern of ... -
The Ecology and Management of Indigenous Forests in Southern Africa
(University of NairobiCollege of Biological and Physical Sciences, 1992)Systematic collecting of Basidio mycetous fungi from Karura Forest was undertaken in the months of April to July 1991. A total of 270 collections were made, some of which have been studied ecologically and identified, and ... -

(University Of Nairobi, 1990)Lake Naivasha is an important freshwater resource for Kenya's foreign-currency-earning agriculture and tourism, and for water-supply. It has always experienced extensive water-level fluctuations as a consequence of irregular ... -
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 ... -
Ecology of Echinometra mathaei (Echinoidea: Echinodermata) at Diani Beach, Kenya
(Department of Zoology, University of Nairobi, Nairobi, Keny, 1971)Studies were carried out on the inner and outer coral reefs at Diani Beach on the Kenya coast to assess the distribution, density and behaviour of Echinometra mathaei (de Blainville). Transects 1 m wide were run on the two ... -
