Effect of nectar robbing on a pollinator-dependent plant

Nectar robbing commonly has negative consequences for the reproductive success of plants.

Because total plant fitness is the result of both female and male functions, Rojas-Nossa et al. studied the effect of nectar robbing on several variables used to characterize both sexual functions of Lonicera etrusca, a pollinator-dependent plant with long tubular flowers that produce abundant nectar. Although nectar robbing was very frequent, no negative consequence for plant reproductive success was found. They propose a combination of morphological and ecological mechanisms that allow plants to compensate for the energetic loss caused by robbers.
