Resource Partitioning and Niche Differentiation in Sympatric Ungulates

Quick fact

In East African savannas, zebras, wildebeests, and Thomson's gazelles coexist by eating different parts of the grass—zebras take the tough upper stems, wildebeests prefer the nutritious middle leaves, and gazelles nibble the short, new growth—a classic example of resource partitioning.

Why this is interesting

Imagine a savanna where zebras, wildebeests, and antelopes all graze side by side. How do they avoid starving each other out?
