Abstract
Since 1963, nonlinear predation theory has predicted that, at low popu lation densities, victim species may well be mutualistic rather than c ompetitive, Theory identifies this mutualism as a principal source of dynamic instability in the interaction, Using gerbils and trained barn owls, we conducted the first (to our knowledge) field tests of the th eory's prediction of mutualism. The behavior of the gerbils confirms i ts existence.
