Negative cascading effects of a predatory fly larva on an ant–plant protective mutualism
In ant–plant mutualisms mediated by plant-based liquid resources (e.g., extrafloral and pericarpial nectar), third-party exploiters are often present. Usually, the costs of having exploiters species seem to ha...
