(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 ... -
Analysis of Short-Term Drought Episodes Using Sentinel-3 SLSTR Data under a Semi-Arid Climate in Lower Eastern Kenya.
(2023-06)This study uses Sentinel-3 SLSTR data to analyze short-term drought events between 2019 and 2021. It investigates the crucial role of vegetation cover, land surface temperature, and water vapor amount associated with ... -
Hourly reference evapotranspiration analysis using synoptic meteorological measurements and ERA5 reanalysis data from Kenyan Counties
(2023-09)Kenya has had five failed rain seasons for the last three years. In this context, there was a mass recurrent crop failure, death of livestock and wildlife, persistent water scarcity, and droughts of varying intensities. ... -
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 ... -
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 ... -
Fine‐scale variation in soil and topography influences herbaceous vegetation and the distribution of large mammalian herbivores
(Wiley, 2023-04)Current understanding of the distribution of vegetation and large mammalian herbivores (LMH) is based on a combination of biogeographic studies and highly controlled field experiments, but a more complete understanding ... -
5. Absentee owners and overlapping home ranges in a territorial species
(2021-01-07)Abstract Understanding animals’ use of space can shed valuable light on multiple other aspects of behavioral ecology, including social organization, dispersal, and foraging efficiency. Home ranges, territories, core areas, ... -
Globalization and Biodiversity Conservation Problems: Polycentric REDD+ Solutions
(MDPI, 2019-02-19)Noise barriers are the most widespread solution to mitigate noise produced by the continuous growth of vehicular traffic, thus reducing the large number of people exposed to it and avoiding unpleasant effects on health. ... -
Faecal Bacterial and Parasitic Contamination of Drinking Water in Eldoret Municipality, Kenya
(2012)Faecal contamination of water can introduce a variety of pathogens into water ways, including bacteria, viruses, protozoans and parasitic worms. Poor excreta disposal is often associated with lack of adequate water supplies, ... -
