Wolves in Yellowstone are a "keystone species" [1].

A year ago, there was a fascinating episode of "Nature" on PBS about keystone species. It's available for free online streaming here [2].

The sad thing with this "keystone species" concept is that people see it as "oh but this weird insect that's about to go extinct in south-east asia is not a keystone species, so whatever."
