Naïve plant communities and individuals may initially suffer in the face of reintroduced megafauna: An experimental exploration of rewilding from an African savanna rangeland
(PLOS ONE, 2021-04-06)Excluding large native mammals is an inverse test of rewilding. A 25-year exclosure experiment in an African savanna rangeland offers insight into the potentials and pitfalls of the rewilding endeavor as they relate to the ... -

Natural Radioactivity and radiological Hazard analysis of Construction stones from various queries in Machakos County Kenya. Radiation Protection Dosimetry.
(2023-07)The radioactivity levels of rocks sampled from the quarries of Kyasioni, Mavoloni and Kathaana located in the lower Eastern County of Machakos in Kenya were determined. Forty-two samples were collected using stratified ... -
PCBs in fish and their cestode parasites in Lake Victoria
(Environ Monit Assess, 2016)Polychlorinatedbiphenyls(PCBs)areclassified as persistent organic pollutants (POPs) regulated by the Stockholm Convention (2001). Although their production and use was stopped almost three decades ago, PCBs are environmental ... -
POPULATION ECOLOGY, DIET AND MOVEMENT OF STRAW-COLOURED FRUIT BATS (Eidolon helvum), WESTERN KENYA
(research gate, 2012-07)The population status, movement, roost-site selection and diet of straw-coloured fruit bats (Eidolon helvum) were studied over a seven-month period in western Kenya. Overall, the bat population fluctuated markedly from as ... -
A Public-Private Partnership Scheme To Avert Desertification in the Drylands of Kenya: Lessons for Social Scientists
(University of Dar es Salaam, 2016)The drylands of Kenya make up about 80% of the total land area and are defined by aridity, thermal stress, soil moisture deficiency and general human want. The poverty bedevilling the drylands leave their inhabitants without ... -
Relationships Between Cattle and Biodiversity in Multiuse Landscape Revealed by Kenya Long-Term Exclosure Experiment
(Elsevier, 2018-05)On rangelands worldwide, cattle interact with many forms of biodiversity, most obviously with vegetation and other large herbivores. Since 1995, we have been manipulating the presence of cattle, mesoherbivores, and ... -
The Role of Selected Environmental Factors on the Regeneration of (Ocotea usambarensis ) in Mount Kenya Forest, Kenya
(International Journal of Agriculture, Environment and Bioresearch, 2018)Despites the propagation efforts, density of Ocotea usambarensis has continued to diminish in the southern slopes of Mount Kenya. The species which is native in the montane forest is seldom on farm and found as remnant ... -

Spatial scales influence long-term response of herbivores to prescribed burning in a savanna ecosystem
(CSIRO PUBLISHING, 2017-04)Both wild and prescribed fire in savanna ecosystems influence habitat use by herbivores by creating or maintaining spatial and temporal heterogeneity in forage quality and vegetation cover. Yet little is known about how ... -
Spawning interactions between hatchery-reared and wild naturalized rainbow trout (Oncorhynchus mykiss, Walbaum, 1792) in high-altitude tropical streams, Kenya
(Wiley, 2022-07)Rainbow trout (Oncorhynchus mykiss) is among the most widely translocated fish species in the world. The current study evaluated the spawning interactions between naturalized and wild rainbow trout from two high-altitude ... -
Stand Composition, Floristic Affinities and Plant Formations in Mau Forests
(Academia, 2014)The Mau ecosystem post-disturbance recovery process, integrity retention and resilience to future disturbances and sustainability remain unknown. In this paper, the ecosystem floristic composition, richness, diversity and ... -
Sustainable Utilization of Wetlands Resources in Selected Areas of Nyamira County, Kenya
(Research journali’s Journal of Geography, 2015)Researches on wetland utilization in Kenya focus more on wetlands located in the ASALs and Lowland areas giving less emphasis to those in high agricultural potential highland areas. This paper examined the utilization of ... -
Synergistic effects of fire and elephants on arboreal animals in an African savanna

Synergistic effects of long-term herbivory and previous fire on fine-scale heterogeneity of prescribed grassland burns
(Ecology, 2020-10)Grassland and savanna ecosystems, important for both livelihoods and biodiversity conservation, are strongly affected by ecosystem drivers such as herbivory, fire, and drought. Interactions among fire, herbivores and ... -
Tree resprout dynamics following fire depend on herbivory by wild ungulate herbivores
(Journal of Ecology, 2019-04)1. Savanna tree cover is dynamic due to disturbances such as fire and herbivory. Frequent fires can limit a key demographic transition from sapling to adult height classes in savanna trees. Saplings may be caught in a ‘fire ... -
The Trend and the Pattern of Seasonal Rainfall in the Period 1993 – 2018 in Embu East Sub County, Kenya
(East African Journal of Environment and Natural Resources, 2020)Kenya, like many countries in the world, is vulnerable to climate variability and change. The livelihood of the people in Embu East Sub-county is highly dependent on rain-fed agriculture so climatic threats affect food and ...
