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 ... -
Seed dispersal by Tana River mangabeys in fragmented gallery forests

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
(British Ecological Society, 2015) -
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 ...
