Impacts of nectar robbing on the foraging ecology of a territorial hummingbird
Behavioural Processes, 2018While the effects of nectar robbing on plants are relatively well-studied, its impacts from the perspective of the pollinators of robbed plants is not. Numerous studies do consider the impacts of robbing on pollinator visitation to robbed plants, but rarely do they focus on its scaled-up impacts on individual pollinator behavior.

Effects of nectar-robbing on plant reproduction and evolution
Frontiers of Biology in China, 2007The relationship between plant and pollinator is considered as the mutualism because plant benefits from the pollinator’s transport of male gametes and pollinator benefits from plant’s reward. Nectar robbers are frequently described as cheaters in the plant-pollinator mutualism, because it is assumed that they obtain a reward (nectar) without providing

Nectar robbing impacts pollinator behavior but not plant reproduction
Oikos, 2016Trait‐mediated indirect effects (TMIEs) refer to interactions in which the effect of one species on another is mediated by the behavior of a third species. A mechanistic approach that identifies the direction and impact of TMIEs can shed light on why different net outcomes are observed in the same general phenomena across systems ...

Consequences of nectar robbing for the fitness of a threatened plant species
Plant Ecology, 2008The effect of nectar robbing on plant fitness is poorly understood and restricted to a few plant species. Furthermore, the available studies generally evaluate the effects of nectar robbing on female fitness, disregarding the male component. Here we measured the effects of the nectar-robbing bumblebees on male (measured as pollen analogue flow distance)

The behavioral ecology of nectar robbing: why be tactic constant?
Current Opinion in Insect Science, 2017How do animals forage for variable food resources? For animals foraging at flowers, floral constancy has provided a framework for understanding why organisms visit some flowers while bypassing others. We extend this framework to the flower-handling tactics that visitors employ. Nectar robbers remove nectar through holes bitten in flowers, often without

Nectar Robbing and Pollination of Lantana camara (Verbenaceae)
Biotropica, 1976Floral robbers are categorized as nectar-foraging, nectar-foraging-perforating, and pollen-foraging. Trigona fulviventris is a nectar-foraging-perforating robber of yellow flowers of Lantana camara. Flower head maturation of L. camara is centripetal and flowers turn from yellow to reddish-orange, resulting in inflorescences of central yellow flowers ...

Nectar robbing in Ipomopsis aggregata : effects on pollinator behavior and plant fitness
Oecologia, 1998Hummingbirds foraging in alpine meadows of central Colorado, United States, face a heterogeneous distribution of nectar rewards. This study investigated how variability in nectar resources caused by nectar-robbing bumblebees affected the foraging behavior of hummingbird pollinators and, subsequently, the reproductive success of a host plant (Ipomopsis ...

AbstractNectar robbing occurs when floral visitors remove floral nectar through floral damage and usually without providing pollination in return. Even though nectar robbing may have negative, neutral or even positive effects on plant fitness, few studies have investigated temporal and spatial variation in robbing rate and their consequences ...

Nectar robbers use a hole made in the perianth to extract nectar. Since robbers may modify plant fitness, they play an important role by driving evolution on floral traits, shaping population structure and influencing community dynamics. Although nectar robbing is widespread in angiosperms, the causes and ecological implications of this behaviour on ...

Differences in morphology among bumblebee species sharing a nectar resource may lead to variation in foraging behaviour and efficiency. Less efficient bumblebees might opportunistically switch foraging strategies from legitimate visitation to secondary robbing when hole‐biting primary robbers are present.
