Environmental parameters and anthropogenic effects predicting the spatial distribution of wild ungulates in the Akagera savannah ecosystem

  • Savannah areas affected by human activities such as livestock keeping and agriculture are often characterized by shifts in landscape structuring, with a predominance of few(er) habitat types. This is typically accompanied by pronounced changes in the communities of ungulates. The aim of this study was to find out whether shifts in ungulate communities in Lake Mburo National Park (LMNP) are primarily predicted by an alteration in the composition of the preferred habitat types or if more complex interactions between habitat changes and the prevalence of ungulates occur. Monthly road counts were used to establish the number of eleven ungulate species in LMNP and adjacent unprotected Ankole Ranching Scheme. The common duiker (Sylvicapra grimmia campbelliae Gray, 1843) was found in more abundance in disturbed areas, while showing a significant change in habitat use. Common duiker tended to use the vegetation type otherwise used by the bushbuck (Tragelaphus scriptus dama Neumann, 1902).

Our results support the claim that the occurrence of ungulates is not only directly affected by the availability of 'suitable' habitats, but behavioural plasticity and competitive exclusion also need to be considered.zeige mehrzeige weniger
