Abstract The hippopotamus grazes nocturnally on land and resides in water during the day. Much of the ingested material must therefore be defecated directly into the aquatic system and can thus be considered an allochthonous resource available to aquatic consumers. The utility of stable isotope analyses of carbon and nitrogen to distinguish hippo faecal matter from other potential basal resources was tested at Lake Naivasha, Kenya. Hippopotami proved faithful to a short grass diet although… Expand
Stable isotope ecology of the common hippopotamus
Isotope profiles of modern hair and modern tooth enamel confirm that H. amphibius has a variable diet in both the short- (seasonal) and long- (sub-decadal) time scales. Expand
Fatty acid analyses provide novel insights on hippo defecation and consequences for aquatic food webs
By defecating grasses into aquatic systems at massive scales and intensities, hippos can initiate complex changes to aquatic ecosystems. However, consequent effects on food webs are not wellExpand
Idiosyncratic responses of meiofaunal assemblages to hippo dung inputs in an estuarine lake
It is concluded that meiofauna are more robust and opportunistic than macrofauna in responding to dung-loading and suggested that high input rates may shift benthic communities from larger macrofaunal groups to smaller meioFaunal assemblages. Expand
A comprehensive biogeochemical record and annual flux estimates for the Sabaki River (Kenya)
Abstract. Inland waters impart considerable influence on nutrient cycling and budget estimates across local, regional and global scales, whilst anthropogenic pressures, such as rising populations andExpand
The ecology and behaviour of the common hippopotamus, Hippopotamus amphibious L., in Katavi National Park, Tanzania : responses to varying water resources
Katavi National Park (KNP) is a stronghold for hippopotami in Tanzania. To predict the probable effects of future changes in water availability, annual variations in rainfall, river level, riverExpand
Trophic structure of an African savanna river and organic matter inputs by large terrestrial herbivores: A stable isotope approach
It is shown that increased terrestrial organic matter by large mammalian herbivores affected trophic diversity and niche sizes for aquatic consumers in rivers draining the African savanna, and linking the density of terrestrial large mammalian Herbivores to aquatic ecosystem structure and function could help manage their populations sustainably.

Diets of modern and late Miocene hippopotamids: Evidence from carbon isotope composition and micro-wear of tooth enamel
Carbon isotope composition and micro-wear analyses of tooth enamel were used to reconstruct the diet of late Miocene hippopotamids unearthed in the Toros-Menalla area, Chad, contemporary to the oldest known hominids, indicating that the modern feeding behaviour of large hippos was already developed at the end of the Miocene.

Large herbivorous wildlife and livestock differentially influence the relative importance of different sources of carbon for riverine food webs
Analysis of the influence of replacing large wildlife with livestock on the relative importance of C3 vegetation, C4 grasses and periphyton on macroinvertebrates in the Mara River shows that replacing wildlife (hippos) with livestock shifts river systems towards greater reliance on autochthonous carbon through an algae-grazer pathway as opposed to reliance on allochth onous inputs of C4 carbon through a detrital pathway.

From introduction to fishery dominance: the initial impacts of the invasive carp Cyprinus carpio in Lake Naivasha, Kenya, 1999 to 2006
Contrary to predictions and despite the increasing carp abundance, there has been macrophyte regeneration in littoral areas since 2004 and there have been substantial increases in areal cover, with coverage in 2006 at levels not observed since the late 1980s, and significant increases in species richness.

Assessing the role of large herbivores in the structuring and functioning of freshwater and marine angiosperm ecosystems
Large aquatic herbivores have strong impacts on associated species and can be critical ecosystem engineers of aquatic systems, with the ability to modify direct and indirect functional pathways in ecosystems. Expand


The use of stable carbon isotopes as tracers of ecosystem functioning in contrasting wetland ecosystems of Lake Victoria, Kenya
Aquatic macrophytes and sediments from two contrasting wetland ecosystems of Lake Victoria, Kenya (Lower Sondu Miriu and Kibos systems) were analyzed for their stable carbon isotopic composition inExpand
Interpreting stable isotopes in food webs: Recognizing the role of time averaging at different trophic levels
Lake Tanganyika, East Africa, has a simple pelagic food chain, and trophic relationships have been established previously from gut-content analysis. Instead of expected isotopic enrichment fromExpand
Seasonal changes in the importance of the source of organic matter to the diet of zooplankton in Loch Ness, as indicated by stable isotope analysis
Zooplankton isotopic signatures shifted seasonally, reflecting a dietary switch from a reliance on allochthonous carbon derived from POM during winter and early spring to heavy dependence on algal production during summer. Expand
Phosphorus inputs to Lake Naivasha, Kenya, from its catchment and the trophic state of the lake
The main river supplying Lake Naivasha, Kenya, the Malewa, drains a catchment given over to largely subsistence cultivation and animal husbandry. The lake itself is the focus for an intensiveExpand
Stepwise enrichment of 15N along food chains: Further evidence and the relation between δ15N and animal age
The isotopic composition of nitrogen was measured in marine and fresh-water animals from the East China Sea, The Bering Sea, Lake Ashinoko and Usujiri intertidal zone. Primary producers, showedExpand
The food habits of wild ungulates in Uganda by analyses of stomach contents
Food eaten by six species of ungulates was studied by analysing stomach contents, using the method developed for faecal analyses, which showed that animal species usually avoided competition by their specialized food habits. Expand
Geochemical and physical characteristics of river and lake sediments at Naivasha, Kenya
Prior studies on Lake Naivasha relevant to understanding sediment dynamics include a bathymetric map, a paleolimnological study of fossil invertebrate assemblages in lake sediment, an overview ofExpand
Water quantity and quality as the factors driving the Serengeti ecosystem, Tanzania
Thirty nine years of rainfall data from 232 sites, 5 years of river discharge data from 3 rivers, 4 years of animal migration data and 4 years of water quality data at 60 sites were explored toExpand
Impact of light regimen and self‐shading by algal cells on primary productivity in the water column of a shallow tropical lake (Lake Naivasha, Kenya)
Self-shading is seen to have a considerable impact on potential productivity and may affect phytoplankton–cyanobacterial community structure with implications for lake management. Expand
