Litter processing and shredder distribution as indicators of riparian and catchment influences on ecological health of tropical streams
(Ecological Indicators, 2014-05)
Terrestrial plant litter is the main source of energy for food webs in forest headwater streams. Leaf litter quality often changes when native tree species are replaced by exotic ones and land use change in
the watershed ...
Macroinvertebrate functional feeding groups in Kenyan highland streams: evidence for a diverse shredder guild
(The Society for Freshwater Science, 2014-02)
Data on the functional composition of invertebrates in tropical streams are needed to develop models
of ecosystem functioning and to assess anthropogenic effects on ecological condition. We collected macroinvertebrates ...
Are Large Herbivores Vectors of Terrestrial Subsidies for Riverine Food Webs?
(Springer Science+Business Media New York, 2015-03-17)
The tropical savannas of Africa have witnessed a
dramatic reduction in native large mammalian
herbivore populations. The consequences of these
changes for terrestrial-aquatic food-web linkages
are poorly documented. ...
Influence of catchment land use and seasonality on dissolved organic matter composition and ecosystem metabolism in headwater streams of a Kenyan river
(Biogeochemistry An International Journal, 2017-01)
Headwater streams influence the biogeochemical characteristics of large rivers and play
important roles in regional and global carbon budgets.
The combined effects of seasonality and land use
change on the biogeochemistry ...
Genetic identification of invasive walking catfish, Clarias batrachus, intermingled with African catfish, C. gariepinus, in South Africa
(African Journal of Wildlife Research 45(1): 55–62 (April 2015), 2015-04)
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 ...
High genetic diversity and population differentiation in Clarias gariepinus of Yala Swamp: evidence from mitochondrial DNA sequences
(Journal of Fish Biology (2016) 89, 2557–2570, 2016-07)
In order to improve the conservation and sustainable utilization of the African catfish Clarias gariepinus of the Yala Swamp in Kenya, genetic diversity and population structure of Lakes Kanyaboli
and Namboyo populations ...
Distribution patterns and diversity of riverine fishes of the Lake Victoria Basin, Kenya
(2020-08)
The Lake Victoria Basin (LVB) is a global hotspot of aquatic biodiversity, but aquatic ecosystems are under threat from multiple stressors. Most studies on fish have focused on Lake Victoria, while patterns of fish diversity, ...
Use of macroinvertebrate assemblages for assessing performance of stabilization ponds treating effluents from sugarcane and molasses processing
(Springer, 2017)
Wastewater discharge from sugarcane processing is a significant pollutant of tropical aquatic ecosystems. For most developing countries, monitoring of the level of pollutants is done mostly through chemical analysis, but ...
Genetic diversity and population structure of the African catfish, Clarias gariepinus (Burchell, 1822) in Kenya: implication for conservation and aquaculture
(Belgian Journal of Zoology, 2017)
African catfish, Clarias gariepinus, is an important species in aquaculture and fisheries
in Kenya. Mitochondrial D-loop control region was used to determine genetic variation and population
structure in samples of C. ...
