Homage to the red queen. II. Coevolutionary response to enrichment of exploitation ecosystems

, and . Theor Popul Biol, (August 1978)

Abstract

The model of predator-victim coevolution developed in the preceding paper (Schaffer and Rosenzweig, 1978) is used to analyze the coevolutionary response to ecosystem enrichment. It is shown that coevolution tends to oppose the destabilization that results from the enrichment itself. In the circumstance that the victims' r and K are proportional, gradual enrichment followed by coevolutionary adjustment actually enhances ecosystem stability.
