Drought‐induced reductions in plant defenses: Insights from extrafloral nectaries in the Caatinga dry forest
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 thi...

Summary: | 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.
