Dammed and damned? Consequences of large scale land use Changes on environment, livelihood and food security in the Yala swamp ecosystem, Kenya, East Africa

Abila, Romulus O.; Nthenge, Agatha M. (2014-03)

African wetlands are among the most productive ecosystems and as such play an important role in ameliorating the effects of global warming, biodiversity conservation as well as major source of natural resources which ...
Genetic diversity and gene flow in Clarias gariepinus from Lakes Victoria and Kanyaboli, Kenya

Abila, Romulus O.; Barasa, J. E.; Grobler, J. P.; Dangasuk, O. G.; Njahira, M. N.; Kaunda-Arara, B. (Taylor & Francis, 2014)

The African catfish Clarias gariepinus is an important species in the rapidly expanding aquaculture industry in East Africa. Most Kenyan catfish farmers use stocks with unknown genetic characteristics, with uncertified ...
Genetic diversity and population structure of the endangered ripon barbel, Barbus altianalis (Boulenger, 1900) in Lake Victoria catchment, Kenya based on mitochondrial DNA sequences

Abila, Romulus O.; Chemoiwa, E. J.; Abila, R.; Macdonald, A.; Lamb, J.; Njenga, E.; Barasa, J. E. (Wiley, 2013)

Approximately 850 bp of the mitochondrial control region was used to assess the genetic diversity, population structure and demographic expansion of the endangered cyprinid Barbus altianalis, a species known to be potamodramous ...
Genetic Identification of Invasive Walking Catfish, Clarias batrachus, Intermingled with African Catfish, C. gariepinus, in South Africa

Abila, Romulus O.; Grobler, J. Paul; Ndyogolo, Sinobongo; Barasa, James; Bindeman, Hesmari; Schlemmer, Andre F. (Southern African Wildlife Management Association, 2015)

Molecular genetic techniques were used to determine the identity of two catfish individuals that could not be identified as indigenous Clarias gariepinus after phenotypic analysis. The unidentified catfish were compared ...
Genetic structure and gene flow in an endangered native tilapia fish (Oreochromis esculentus) compared to invasive Nile tilapia (Oreochromis niloticus) in Yala swamp, East Africa

Abila, Romulus O.; Angienda, Paul O.; Lee, Hyuk J.; Elmer, Kathryn R.; Waindi, Eliud N.; Meyer, Axel (2011)

The introduction of invasive Nile tilapia (Oreochromis niloticus), and the rapacious predator Nile perch (Lates niloticus), into Lake Victoria resulted in a decline in population sizes, genetic diversity and even extirpation ...
Physico-chemical and bacteriological quality assessment of shallow wells in Kitui town, Kenya

Abila, Romulus O.; Muthangya, Mutemi; Mutuku, Eunice; Mutati, Kennedy; Munguti, Mutinda; Musyoka, Cecilia M. (Wudpecker Journals, 2012-03)

Kitui town, a small but fast growing town in arid south-eastern Kenya faces unreliable water supply and residents are highly dependent on shallow wells as the main source of water for domestic use. A study was carried ...
Population-structure and genetic diversity in a haplochromine fish cichlid of a satellite lake of Lake Victoria

Abila, Romulus O.; Barluenga, M.; Engelken, J.; Meyer, A.; Salzburger, W. (Wiley, 2004)

The approximately 500 species of the cichlid fish species flock of Lake Victoria, East Africa, have evolved in a record-setting 100 000 years and represent one of the largest adaptive radiations. We examined the population ...
Preliminary gut content and dentition analysis reveal subtle resource partitioning and feeding adaptations within a haplochromine cichlid community of Lake Victoria satellite lake

Abila, Romulus O. (2011-06)

The trophic relationships between six haplochromine cichlids of Lake Kanyaboli, a satellite lake of Lake Victoria that has not been infested by the Nile perch (Lates niloticus), were studied as a first step towards ...
The role of the Yala swamp lakes in the conservation of Lake Victoria region haplochromine cichlids: Evidence from genetic and trophic ecology studies

Abila, Romulus O.; Salzburger, Walter; Ndonga, Millicent F.; Owiti, Dickson O.; Barluenga, Marta; Meyer, Axel (Wiley, 2008)

Lake Kanyaboli, an isolated satellite lake of Lake Victoria, has been suggested as a potential refugium for haplochromine cichlids that have gone extinct in the main basin of Lake Victoria. Mitochondrial DNA (mtDNA) molecular ...
