Marbled lungfish growth rates in Lake Baringo, Kenya, estimated by mark-recapture
(Wiley Online Library, 2006-02)Mark-recapture was used to quantify the relationship between body mass (MT) and individual growth rates of sub-adult marbled lungfish Protopterus aethiopicus in Lake Baringo, Kenya. Specific growth rate (in mass) was found ... -
Molecular typing of Trichomonas vaginalis isolates by actin gene sequence analysis and carriage of T. vaginalis viruses
(Parasites & Vectors, 2017)Background: The protozoan parasite Trichomonas vaginalis is the most common non-viral, sexually transmitted pathogen. Although T. vaginalis is highly prevalent among women in Kenya, there is lack of data regarding genetic ... -
Morphomeristic study of sympatric Barbus species from a man-made reservoir in upland Kenya
(Wiley Online Library, 2012-03)The small Barbus are a widely distributed group of freshwater fishes in Africa whose taxonomy is yet to be resolved. This study used morphomeristic analysis of characters to distinguish and describe sympatric Barbus species ... -
Morphomeristic study of sympatric Barbus species from a man-made reservoir in upland Kenya
(African Journal of Ecology, 2012-03)Abstract The small Barbus are a widely distributed group of freshwater fishes in Africa whose taxonomy is yet to be resolved. This study used morphomeristic analysis of characters to distinguish and describe sympatric ... -
Movement and habitat use by the marbled lungfish Protopterus aethiopicus Heckel 1851 in Lake Baringo, Kenya
(Kluwer Academic Publishers, 2005-03)The marbled lungfish, Protopterus aethiopicus, a recent introduction into Lake Baringo, Kenya is now an important commercial species there. Because little is known about its behaviour, we used ultrasonic telemetry to ... -
Movement ecology of black marlin Istiompax indica in the Western Indian Ocean
(Journal of Fish Biology published by John Wiley & Sons Ltd on behalf of Fisheries Society of the British Isles, 2021-05)The black marlin Istiompax indica is an apex marine predator and is susceptible to overfishing. The movement ecology of the species remains poorly known, particularly within the Indian Ocean, which has hampered assessment ... -
Nanopore metatranscriptomics reveals cryptic catfsh species as potential Shigella fexneri vectors in Kenya
(www.nature.com/scientificreports, 2022)Bacteria in the Shigella genus remain a major cause of dysentery in sub-Saharan Africa, and annually cause an estimated 600,000 deaths worldwide. Being spread by contaminated food and water, this study highlights how ... -
