Nectar robbers and simulated robbing differ in their effects on nectar microbial communities
Plant Species BiologyAbstract Floral nectar contains microbes that can influence nectar chemistry and pollinator visitation, and these microbial communities can be affected by pollinators in turn. Some flowers are also visited by nectar robbers, which feed on nectar through holes cut in floral tissue.

Nectar Robbing: Ecological and Evolutionary Perspectives
Annual Review of Ecology, Evolution, and Systematics, 2010 Not all floral visitors attracted to flowers are pollinators. Instead, some visitors circumvent the floral opening, usually removing nectar without contacting the anthers and/or stigma. Here we review the evolutionary ecology of nectar robbing from both the plant and animal perspective.

Nectar robbing and plant reproduction: an interplay of positive and negative effects
Oikos, 2021Nectar 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 neutral, to positive according to life history traits of the interacting organisms and the ecological mechanisms involved.

CONSEQUENCES OF NECTAR ROBBING FOR REALIZED MALE FUNCTION IN A HUMMINGBIRD-POLLINATED PLANT
Ecology, 2000The effects of nectar robbers on plants and their mutualistic pollinators are poorly understood due, in part, to the paucity of studies examining male reproductive success in nectar-robbed plants. Here we measured the effects of a nectar-robbing bumblebee, Bombus occidentalis, on realized male reproductive success (seeds sired) in a hummingbird ...

Corolla stickiness prevents nectar robbing in Erica
Journal of Plant Research, 2021Floral stickiness is a rare trait with unknown function, but it is common in the mega-diverse Cape genus Erica (Ericaceae). This study investigated the role of stickiness measured as adhesive strength in Erica as protection against nectar robbing and its correlation with floral traits.

Honeybees with extensive foraging experience rob nectar more frequently
The Science of Nature, 2021Not all flower-visiting animals act as pollinators; some visitors engage in foraging nectar without pollen transfer. The tendency to rob nectar is related to visitors' morphological traits and rewards per foraging effort, and drivers of this variation within visitor species are largely unknown.

Variation in nectar robbing over time, space, and species
Oecologia, 2002Spatiotemporal variation in the interactions among plants and animals is widespread; yet our conceptual and empirical understanding of this variation is limited to a few types of visitors, mainly herbivores, pollinators, seed predators, and seed dispersers. Despite the ubiquity of nectar robbing and the strength of its effects on plant fitness, we know
