Abstract: The proposal that species diversity in an ecosystem makes it more resistant to perturbation is intuitively attractive, yet this is often not supported by either natural or model systems. An example that does support the proposal is now shown in populations of acorn woodpeckers. These birds rely on oak trees for food, and their population density is limited not by the overall density of trees, but by the number of species.
