WASHINGTON, D.C. — Placing two species of flour beetle in the same jar of flour needn't always result in one species driving the other to extinction, as ecologists have thought. A new mathematical model presented January 5 at the annual Joint Mathematics Meetings shows how sometimes these two competing species can coexist.

The new research raises questions about a common assumption in ecology, the idea that only one species can survive in a specific ecological niche. Like similar species of...
