The most effective pollinator principle applies to new invasive pollinators
(2018)
G. L. Stebbins' most effective pollinator principle states that when pollinators are not limiting, plants are expected to specialize and adapt to the most abundant and effective pollinator species available. In this study, ...
Behind the pollination syndrome: Nectar ecology and the role of diurnal and nocturnal pollinators in the reproductive success of Inga sessilis (Fabaceae)
(Wiley, 2012-07)
Inga species present brush-type flower morphology allowing them to be visited by
distinct groups of pollinators. Nectar features in relation to the main pollinators
have seldom been studied in this genus. To test the ...
Disruption of pollination services by invasive pollinator species
(Springer, 2017)
Frequency of visits by ants and their effectiveness as pollinators of Condalia microphylla Cav.
(Elsevier, 2014-06)
The effect of a pollinator species on a plant depends on their interaction frequency and the pollinator's effectiveness. The role of ants as pollinators is highly variable, in some cases they act as true pollinators and ...
Persistence of plants and pollinators in the face of habitat loss: Insights from trait-based metacommunity models
(Elsevier Academic Press Inc, 2015-11)
The loss of natural habitats is one of the main causes of the global decline of biodiversity. Understanding how increasing habitat loss affects ecological processes is critical for mitigating the effects of environmental ...
Effects of self-, chase and mixed self/cross-pollinations on pistil longevity and fruit set in Ceiba species (Bombacaceae) with late-acting self-incompatibility
(Oxford University Press, 2004-08-01)
Background and aims Late-acting self-incompatibility (LSI). in which selfed flowers fail to form fruits despite apparently successful growth of the pollen tubes to the ovules, is a contentious and still poorly understood ...

Pollination ecology of the Cerrado species Eschweilera nana (Lecythidaceae subfam. Lecythidoideae)
(2013-09-06)
Eschweilera nana is pollinated by a guild of pollinators consisting of mostly bees. Effective pollinators are large bees able to force their way into the closed androecium to access nectar. The morphology of the flowers ...
Temporal variation in pollination services to Cucurbita moschata is determined by bee gender and diversity
(Wiley-Blackwell, 2018-11)
It has been proposed that species-rich insect communities and species turnover across landscapes enhance the pollination efficiency of crops through complementarity, where both the dominant and less abundant species ...
Weak trophic links between a crab-spider and the effective pollinators of a rewardless orchid
(2015-01)
Sit and wait predators hunting on flowers are considered to be exploiters of plant–pollinator mutualisms. Several studies have shown that plant–pollinator interactions can be highly susceptible to the impact of a third ...
