Highlights•Pollinator cognition is an under-studied driver of pollinator-microbe-plant
interactions.•Microbially-altered floral phenotypes affect pollinator foraging …

Animals foraging from flowers must assess their environment and make critical decisions
about which patches, plants, and flowers to exploit to obtain limiting resources. The cognitive …

Nectar robbers are animals that extract nectar through holes made in floral tissues. This
behaviour has a wide spectrum of consequences for the plant that range from negative, to …

Nectar robbing can affect plant reproductive success directly by influencing female and male
fitness, and indirectly by affecting pollinator behavior. Flowers have morphological and …

Floral trait variation may help pollinators and nectar robbers identify their target plants and,
thus, lead to differential selection pressure for defense capability against floral antagonists …

Nectar robbing–harvesting nectar illegitimately–can have a variety of outcomes for plant
sexual reproduction and for the pollinator community. Nectar robbers can damage flowers …

The ontogeny of nectar robbing by pollinators is not well understood. In this study, we
investigated the interplay of pre-existing biases and experience in the expression of nectar …

Olfactory cues constitute one of the most important plant-pollinator communication channels.
Specific chemical components can be associated with specific pollinator functional groups …

With many plant–pollinator interactions undergoing change as species' distributions shift, we
require a better understanding of how the addition of new interacting partners can affect …

How do nectar-feeding animals choose among alternative flower-handling tactics? Such
decisions have consequences not only for animal fitness (via food intake) but for plant …
