Water stress strengthens ant–plant mutualism

An Azteca pittieri ant patrols the surface of an Ecuador laurel tree (Cordia alliodora) in Jalisco, Mexico. When water is scarce, trees support more sap-feeding scale insects that feed defending ants, and ants provide better defense against leaf-eating pests. Pringle et al. (e1001705) show that this pattern can be explained by the high costs of leaf loss to trees when conditions are dry.
