Lion and spotted hyena distributions within a buffer area of the Serengeti-Mara ecosystem

Abstract Most large carnivore populations are declining due to anthropogenic activities including direct persecution, prey depletion, habitat loss and degradation. protected areas (PAs) can help maintain viable large carnivore populations; however, anthropogenic activities occurring near and within...
