Diversity of Taenia and Hydatigera (Cestoda: Taeniidae) in domestic dogs in Kenya
(University of Nairobi, 2020)Taenia species of domestic dogs can cause cysticercosis and coenurosis in a wide range of intermediate hosts including humans. Most taeniids of dogs are globally distributed, but some wildlife-transmitted species can be ... -
Divine Control Over Weather
(Department of Meteorology, 1998)Western Kenya, which comprise the highlands west of the Rift Valley and the Lake Victoria basin, receive substantial amount of rainfall almost throughout the year. This region has therefore a high agricultural potential. ... -

A DNA-barcode for Melia volkensii Gürke (Meliaceae) and its phylogenetic relationship with some economically important relatives
(University of Nairobi, 2016)The study reports the first DNA-barcode and molecular phylogeny of the East African endemic tree species Melia volkensii using the standard two-locus plant barcoding genes (rbcL and matK). The two genes were amplified and ... -
Does Farm Worker Health Vary Between Localised And Globalised Food Supply Systems?
(University of NairobiInstitute For Climate Change and Adaptation, 2009-10)Significant environmental benefits are claimed for local food systems, but these biophysical indicators are increasingly recognised as inadequate descriptors of supply chain ethics. Social factors such as health are also ... -
