Drought-induced reductions in plant defenses

Extrafloral nectaries (EFNs) are anti-herbivory defense-related glands. We measured morphological and anatomical EFN traits in Pityrocarpa moniliformis trees along a rainfall gradient in Caatinga dry forest. We observed a reduction in structural EFN traits as rainfall decreased. We conclude that this reduction is a cost-saving strategy, probably mediated by ants.
