The larger, less fastidious feeders, the zebras, move in first; the choosier, smaller wildebeests come later; and the smallest species of all, Thomson's gazelle, arrives last.

体型较大、不太挑食的斑马最先进入；比较挑剔、身材苗条的牛羚随后出现；而最小的汤姆逊瞪羚，则落在最后。

That is why the smallest of the herbivores, Thomson's gazelle, lives on fruit that is very nutritious but too thin on the ground to support a larger animal.

那就解释了为什么最小型的食草动物，汤普森瞪羚，能以水果为食；虽然水果非常有营养，但是在地面上太稀少，不足以维持体型更大的动物生存。
