Spatiotemporal Variations in Nectar Robbing and Its Effects on Reproduction in Salvia castanea Diels (Lamiaceae) [PDF]

open access: yesPlants
Nectar robbing typically reduces nectar availability to pollinators, damages flower structure, and/or induces secondary robbing. Consequently, it may reduce pollen deposition and seed set, increase pollination efficiency and outcrossing, and/or not ...

Floral visitors of sesame (Sesamum indicum L.): Elucidating their nectar-robbing behaviour and impacts on the plant reproduction. [PDF]

open access: yesPLoS ONE
Nectar robbing is common in angiosperms, especially in long tubular flowers or flowers with spurs that keep nectar out of reach of visitors. However, the robbing behaviour of bees is less understood.

A Decrease in the Staminode-Mediated Visitor Screening Mechanism in Response to Nectar Robbers Positively Affects Reproduction in Delphinium caeruleum Jacq. ex Camb. (Ranunculaceae) [PDF]

open access: yesBiology, 2022
Nectar-robbing insects, which are frequently described as cheaters in plant–pollinator mutualisms, may affect plant reproductive fitness by obtaining nectar rewards without providing pollination services.

Nectar robbing by the invasive bumblebee Bombus terrestris (Apidae) changes the behavior of native flower visitors of Fuchsia magellanica Lam. (Onagraceae) but not seed set [PDF]

open access: yesPeerJ
Mutualisms between plants and pollinators may be threatened by nectar robbers, as these animals typically consume nectar without providing the essential pollination service.

Impact of Striped-Squirrel Nectar-Robbing Behaviour on Gender Fitness in Alpinia roxburghii Sweet (Zingiberaceae). [PDF]

open access: yesPLoS ONE, 2015
Nectar-robbing has the potential to strongly affect male and female reproductive fitness of plants. One example of nectar theft is that shown by striped-squirrels (Tamiops swinhoei) on a number of ginger species, including Alpinia roxburghii and A ...

Flower color variation in Digitalis purpurea: Pollination and soil influences across native and introduced populations. [PDF]

open access: yesAm J Bot
Abstract Premise Flower color, a key trait influencing plant–pollinator interactions, may be influenced by abiotic factors such as soil. We investigated association between pollinators, soil characteristics, and flower color variations in Digitalis purpurea across native populations in Sweden and introduced populations in Bolivia.

Geographic variation in resistance to nectar robbing and consequences for pollination [PDF]

open access: yesAmerican Journal of Botany, 2016
PREMISE OF THE STUDY:Floral evolution is frequently ascribed to selection by pollinators, but may also be shaped by antagonists. However, remarkably few studies have examined geographic mosaics in resistance to floral antagonists or the consequences for other floral interactions.METHODS:Gelsemium sempervirens experiences frequent nectar robbing in ...

Mutualism and Antagonism in a Post‐Extinction Hawaiian Bird–Lobelioid Pollination System

open access: yesEcology and Evolution
Extinction of specialized pollinators can alter the balance between mutualism and antagonism in plant–animal interactions, yet the mechanistic consequences of partner loss remain poorly resolved. We examined plant–bird interactions among three endangered

Yeast volatiles promote larceny in bumble bee behavior [PDF]

open access: yesiScience
Summary: The proximate mechanisms that encourage flower visitors to choose to seek benefits without conferring a service in return, such as robbing flowers of their nectar without providing any pollination, remain largely unknown.

Effects of nectar robbing on male and female reproductive success of a pollinator-dependent plant. [PDF]

open access: yesAnn Bot, 2016
Nectar robbers affect host fitness in different ways and by different magnitudes, both directly and indirectly, and potentially constitute an important part of pollination interactions. The aim of this study was to assess the effect of nectar robbing on several variables that characterize the reproductive success of Lonicera etrusca, a pollinator ...
