A novel meroterpenoid cabagranin D was isolated with related neolignans cabagranins A–C from the leaves of Piper cabagranum (Costa Rica). Cabagranins A–C represent the first examples of 3,3′-neolignans isolated from the plant genus Piper, and t

Summary: Nectar chemistry can influence the behavior of pollinators in ways that affect pollen transfer, yet basic questions about how nectar chemical diversity impacts plant-pollinator relationships remain unexplored. For example, plants’ capacity

Diverse mixtures of plant natural products play an important role in plant-herbivore-parasitoid interactions. In the pursuit of understanding these chemically-mediated interactions, we are often faced with the challenge of determining ecologically an

Foundational hypotheses addressing plant–insect codiversification and plant defense theory typically assume a macroevolutionary pattern whereby closely related plants have similar chemical profiles. However, numerous studies have documented variati
