At a smaller spatial scale, periodic fires during the dry season create patches of highly nutritious grazing that are eaten in preference to the surrounding older patches of less palatable vegetation. The 物種 interactions between herbivores and plants, and carnivores and herbivores, are hierarchically nested in the Serengeti 食物網, with the la
