Floral nectar guide patterns discourage nectar robbing by bumble bees. [PDF]

PLoS ONE, 2013
Floral displays are under selection to both attract pollinators and deter antagonists. Here we show that a common floral trait, a nectar guide pattern, alters the behavior of bees that can act opportunistically as both pollinators and as antagonists ...

The Sensory and Cognitive Ecology of Nectar Robbing [PDF]

Frontiers in Ecology and Evolution, 2021
Animals foraging from flowers must assess their environment and make critical decisions about which patches, plants, and flowers to exploit to obtain limiting resources. The cognitive ecology of plant-pollinator interactions explores not only the complex

Nectar robbing in the trainbearers (Lesbia, Trochilidae) [PDF]

PeerJ, 2020
Many flower visitors engage in floral larceny, a suite of so-called ’illegitimate’ visits in which foragers take nectar without providing pollination services.

Social transmission of nectar-robbing behaviour in bumble-bees. [PDF]

Proc Biol Sci, 2008
Social transmission of acquired foraging techniques is rarely considered outside of a vertebrate context. Here, however, we show that nectar robbing by bumble-bees ( Bombus terrestris )—an invertebrate behaviour of considerable ecological significance—has the potential to spread through a population at the ...

Nectar replenishment maintains the neutral effects of nectar robbing on female reproductive success of Salvia przewalskii (Lamiaceae), a plant pollinated and robbed by bumble bees. [PDF]

Ann Bot, 2017
It has been suggested that the dynamics of nectar replenishment could differ for flowers after being nectar robbed or visited legitimately, but further experimental work is needed to investigate this hypothesis. This study aimed to assess the role of nectar replenishment in mediating the effects of nectar robbing on pollinator behaviour and plant ...

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

Am 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.

Yeast volatiles promote larceny in bumble bee behavior [PDF]

iScience
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.

The Hole Truth: Why Do Bumble Bees Rob Flowers More Than Once? [PDF]

Plants
Primary nectar-robbers feed through holes they make in flowers, often bypassing the plant’s reproductive organs in the process. In many robbed plants, multiple holes are made in a single flower.

On the Limits of Alpine Plants: A Systematic Review of the Factors Behind Species' Elevational Range Limits. [PDF]

Ecol Evol
This systematic review of 107 studies on the factors behind the elevational range limits of alpine vascular plants shows a persistent emphasis on upper limits and abiotic factors, especially temperature, while work at lower limits is more evenly distributed across water availability, plant–plant interactions, and selection/local adaptation.

More than Moths: Flower Visitors of a Night-Blooming Plant in South Florida Pine Rocklands, USA [PDF]

Plants, 2022
Plants whose flowers open at night but remain open during the day also attract diurnal flower visitors, potentially boosting their pollination rates and providing resources that can support diverse arthropod communities.
