Interações bióticas demandam o estabelecimento prévio de vias de comunicação planta-animal, as quais são essencialmente moduladas por sinais visuais e químicos. Dentre os caracteres relacionados à polinização, a cor, o ...

Although predators can affect foraging behaviors of oral visitors, rarely is it known if these top-down effects of predators may cascade to plant fitness through trait-mediated interactions. In this study we manipulated ...

1. Flower-dwelling predators may interfere in plant–pollinator interactions through changes in pollinator behaviour, leading to a reduction in pollination services. Although the context-dependency of tri-trophic interactions ...

Regulation of flowering by endogenous and environmental signals ensures that reproduction occurs under optimal conditions to maximize reproductive success. Involvement of the growth regulator gibberellin (GA) in the control ...

The study of multi-modal communication has only recently been extended to innate and learned interactions between flowers and their animal visitors, and usually only to pollinators. Here we studied the relevance of floral ...

Specialization in nectarivory is an uncommon condition among bats, and it is restricted to two subfamilies of neotropical phyllostomids (Glossophaginae and Lonchophyllinae) which encompass dozens of bats with striking ...
