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 ...
Fish assemblages and size-spectra variation among rivers of Lake Victoria Basin, Kenya
(Ecological Indicators, 2020-07)
Riverine ecosystems are some of the most biologically diverse on earth, but are also among the most threatened
by anthropogenic actions. Lack of local-scale studies monitoring changes in riverine populations makes it ...
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 ...
Hippopotamus are distinct from domestic livestock in their resource subsidies to and effects on aquatic ecosystems
(royalsocietypublishing.org/journal/rspb Proc. R. Soc., 2020-03)
In many regions of the world, populations of largewildlife have been displaced
by livestock, and this may change the functioning of aquatic ecosystems owing
to significant differences in the quantity and quality of their ...
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 ...
Habitat structure determines the abundance of the Endangered Sharpe’s Longclaw Macronyx sharpei (Aves: Passeriformes: Motacillidae) at Timau montane grasslands in central Kenya
(Journal of Threatened Taxa, 2020)
Understanding the habitat selecton and structure of a species is critcal for developing evidence-centered conservaton actons.
Sharpe’s Longclaw Macronyx sharpei, a passerine bird endemic to Kenya, is threatened by reductons ...
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 ...
The multilevel society of a small brained bird
(Current Biology, 2019)
Animal societies can be organised in
multiple hierarchical tiers [1]. Such
multilevel societies, where stable
groups move together through the
landscape, overlapping and associating
preferentially with specifi c ...
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 ...
