We studied consequences of storm damage on buttonwood (Conocarpus erectus) shrubs and their herbivores in the Bahamian islands.
Buttonwood is polymorphic, with green shrubs producing few leaf trichomes and silver shrubs covered in dense trichomes. We first
characterize traits of green vs. silver shrubs relevant for herbivores, and then assay damage by two prominent insects. Next, on
replicated islands, we experimentally address how different types of storm damage (simulated hurricane surge damage vs. simulated
intense wind) affected phenotypic traits of both buttonwood morphs and subsequent herbivory over a one-year sampling period. Our
results show that although leaves produced by green shrubs are 21% tougher than leaves produced by silver shrubs, green leaves have
16% higher nitrogen concentrations and greater levels of herbivory. Consistent with previous observational studies of a natural hurricane
