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 ...
Assessment of theFisheries Status in River Molo to Guide the Management on its Fisheries
(African Journal of Education, Science and Technology, 2018)
Rivers provide a suite of ecosystem goods and services to fisheries as well as water that benefit the domestic and industrial use of the riparian communities. The increasing intensification of ...
EFFECTS OF BIOFLOC TECHNOLOGY ON GROWTH PERFORMANCE OF NILE TILAPIA (Oreochromis Niloticus)FINGERLINGS AND MICROBIAL COLONIZATION IN THE SYSTEM.
(International Journal of Agriculture, Environment and Bioresearch, 2018)
Aquaculture intensification is characterized by high stocking density and need of high quality and quantity of artificial feed. Increased fish biomass and feed input brings about rapid deterioration ...
Shifts in the food of Nile perch (Lates niloticus) in Lake Victoria
(John Wiley & Sons Australia, Ltd, 2018-11)
The study investigated diet of Nile perch in Lake Victoria and compared results with
past data from the same lake in order to analyse diet shifts over time. Fish samples
(2020) were collected by seining and trawling from ...
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 ...
