Predators can learn a novel prey—and that learning can reverse who wins indirect competition
WHAT THE EVIDENCE SAYS
A one-predator/two-prey model shows that novel prey can gain a temporary refuge from naïve predators and become the stronger apparent competitor. Faster social learning erodes that refuge and can permit coexistence; under cycling dynamics, the same mechanism can even generate apparent mutualism or apparent predation.
WHY IT MATTERS / OUR READ
Social learning is not just individual behavior in this model; it changes community-level outcomes. That makes predator experience a plausible missing state variable when managers interpret invasion or prey-switching dynamics.
CAVEATS / UNCERTAINTY
This is theory, not a field test. Outcomes depend on model structure and learning assumptions and should generate empirical hypotheses rather than be treated as a management prescription.
