Trophic structure of an African savanna river and organic matter inputs by large terrestrial herbivores: A stable isotope approach
(John Wiley & Sons Ltd ; Freshwater Biology., 2018-06)
. Knowledge of trophic structure is important to understand sources and pathways
of energy resources in community ecology and to identify determinants of
ecosystem changes. Yet, little is known from rivers of African ...
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 ...
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. ...
