This theory was outlined by Robert MacArthur and E. O. Wilson in The Theory of Island Biogeography, and elements adapted from this theory are incorporated into life history theory.
Laurence Mueller criticized this theory by analogizing it to frictionless hockey pucks and Carnot cycles.  A study by Long and Long using Drosophila melanogaster as well as a study by Templeton and Johnson using Drosophila mercatorum weakened the empirical evidence for this theory. The Intermediate Disturbance Hypothesis outlines a scenario where both strategies in this theory may coexist and prosper. This theory was outlined by Robert MacArthur and E. O. Wilson in The Theory of Island Biogeography, and elements adapted from this theory are incorporated into life history theory. This theory focuses on two namesake variables in the Verhulst equation.
