Animal subsidies can provide an important food source to recipient food webs. Hippos, along with other megafauna, have declined at rapid rates outside conservation areas. Hippos provide a large and important resource subsidy in aquatic systems through their dung. Preliminary data from the Mara River in Kenya show that the amount of dung positively correlates with invertebrate biomass. We conducted two artificial stream experiments to test a) if invertebrates use hippo dung as habitat and/or food and b) if hippo dung can increase stability in a river food web. We set up two experiments, where each experiment had 20 artificial streams that were inoculated with invertebrates and algae. We had three treatments – boiled (habitat), blended (food), or unprocessed (habitat and food) hippo dung – and we used a gradient design, following dung concentrations observed in the Mara River. For the second experiment we added a nutrient spike as a disturbance to all the streams to test food web stability. We measured algal, benthic and emerging invertebrate biomass after two weeks. Across both experiments , algal biomass was highest in streams with blended dung, while there was no difference in algal biomass after boiled dung was added. Invertebrate biomass increased with more hippo dung across all three treatments, but we saw the strongest increase with the habitat and food treatment, followed closely by the food only treatment. While we saw higher algal biomass after our nutrient disturbance, we saw little difference in benthic and emerging invertebrate biomass. Our results indicate that larger quantities of hippo dung provides both food and habitat for invertebrates and stability in rivers food webs.
