Assessment of drivers of forest changes using multi-temporal analysis and boosted regression trees model: a case study of Nyeri County, Central Region of Kenya
(Modeling Earth Systems and Environment, 2020-05-06)
The Central Region of Kenya has undergone significant changes in land cover due to a broad range of drivers. These changes are more pronounced in forestland conversions. Past researches within the study area have identified ...
Fine-scale habitat heterogeneity influences browsing damage by elephant and giraffe
(Wiley Publishers, 2020-06)
Effects of large mammalian herbivores on woody vegetation tend to be heterogeneous in space and time, but the factors that drive such heterogeneity are poorly understood. We examined the influence of fine-scale habitat ...
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 ...
The Biological Assessment and Rehabilitation of the World’s Rivers: An Overview
(Water, 2021-01-31)
The biological assessment of rivers i.e., their assessment through use of aquatic assemblages,
integrates the effects of multiple-stressors on these systems over time and is essential to evaluate
ecosystem condition and ...
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 ...
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 ...

Anthropogenic activities affect forest structure and arthropod abundance in a Kenyan biodiversity hotspot
(2023-07)
Land-use change remains the main threat to tropical forests and their dependent fauna and flora, and degradation of existing forest remnants will further accelerate species loss. Forest degradation may result directly from ...
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 ...
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 ...
