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 ...
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 ...
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 ...
Dynamics in Organic Matter Processing, Ecosystem Metabolism and Trophic Sources for Consumers in the Mara River, Kenya
(CRC Press/Balkema PO Box 11320, 2301 EH Leiden, The Netherlands e-mail: Pub.NL@taylorandfrancis.com www.crcpress.com – www.taylorandfrancis.com, 2015-03)
