Costs of floral larceny: A meta‐analytical evaluation of nectar robbing and nectar theft on animal‐pollinated plants

Ecology
Abstract Mutualistic interactions are biological markets in which different species exchange commodities to mutual benefit. Mutualisms are, however, susceptible to exploitation, with some individuals taking without reciprocating. While it is generally assumed that exploiters will inflict fitness costs, evidence for such costs is mixed

NECTAR-ROBBING BUMBLE BEES REDUCE THE FITNESS OFIPOMOPSIS AGGREGATA(POLEMONIACEAE)

Ecology, 1999
The removal of floral nectar by nectar robbers may change the behavior of legitimate pollinators and, consequently, the pollination and fertilization success of flowering plants. We measured the effects of a nectar-robbing bumble bee, Bombus occidentalis, on male and female reproductive success of Ipomopsis aggregata (Polemoniaceae).

Immediate Effects of Nectar Robbing by Palestine Sunbirds (Nectarinia osea) on Nectar Alkaloid Concentrations in Tree Tobacco (Nicotiana glauca)

Journal of Chemical Ecology, 2014
Plant secondary metabolites (PSMs), such as alkaloids, are often found in many parts of a plant, including flowers, providing protection to the plant from various types of herbivores or microbes. PSMs are also present in the floral nectar of many species, but typically at lower concentrations than in other parts of the plant.

Trait matching affects the probability of nectar robbing in plant–pollinator networks

Oikos
Mutualistic interactions support many ecological functions including pollination. Interactions are, however, vulnerable to cheaters, species that benefit from interactions without providing anything in return. Nectar robbing, where the nectar is depleted but the flower not pollinated, is a well‐known example of cheating and often ...
