Pollination efficiency of artificial and bee pollination practices in kiwifruit
(Elsevier Science, 2019-02)
The area cultivated with pollinator-dependent crops is increasing worldwide, while a shortfall in pollinator availability is a growing problem in many agroecosystems. For this reason, many highly pollinator-dependent crops ...
The importance of pollinator generalization and abundance for the reproductive success of a generalist plant
(Public Library Science, 2013-10-07)
Previous studies have examined separately how pollinator generalization and abundance influence plant reproductive success, but none so far has evaluated simultaneously the relative importance of these pollinator attributes. Here we evaluated the extent to which pollinator generalization and abundance influence plant reproductive success per visit and at the population level on a generalist plant, Opuntia sulphurea (Cactaceae). We used field experiments and path analysis to evaluate whether the per-visit effect is determined by the pollinator?s degree of generalization, and whether the population level effect (pollinator impact) is determined by the pollinator?s degree of generalization and abundance. Based on the models we tested, we concluded that the per-visit effect of a pollinator on plant reproduction was not determined by the pollinators? degree of generalization, while the population-level impact of a pollinator on plant reproduction was mainly determined by the pollinators? degree of generalization. Thus, generalist pollinators have the greatest species impact on pollination and reproductive success of O. sulphurea. According to our analysis this greatest impact of generalist pollinators may be partly explained by pollinator abundance. However, as abundance does not suffice as an explanation of pollinator impact, we suggest that vagility, need for resource consumption, and energetic efficiency of generalist pollinators may also contribute to determine a pollinator?s impact on plant reproduction....
Generalized pollination system: are floral traits adapted to different pollinators?
(Kluwer Academic Publishers, 2014)
Flowers that are pollinated both during the day and at night could exhibit two different groups of pollinators and produce two different sets of attractants and rewards. We explored the patterns of emission of flower scents ...
Flower reshaping in the transition to hummingbird pollination in Loasaceae subfam. Loasoideae despite absence of corolla tubes or spurs
(Springer, 2016-03)
Many angiosperm lineages present transitions from bee to hummingbird pollination. The flower design in most of these lineages includes either corolla tubes or nectar spurs, structures that commonly experienced an elongation ...
Wild pollinators enhance fruit set of crops regardless of honey-bee abundance
(American Association For The Advancement Of Science, 2013-03)
The diversity and abundance of wild insect pollinators have declined in many agricultural landscapes. Whether such declines reduce crop yields, or are mitigated by managed pollinators such as honey bees, is unclear. We ...
Deconstructing pollinator community effectiveness
(Elsevier Inc., 2017-06)
Effective pollination is a complex, context-dependent phenomenon determined by both species-level and community-level factors. While pollinator communities are constituted by interacting organisms in a shared environment, ...
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 ...
Reproductive ecology of the bird-pollinated Nicotiana glauca across native and introduced ranges with contrasting pollination environments
(Springer, 2019-10)
Introduced plants become decoupled from their usual pollinators and by relying on resident pollinator species or other reproductive strategies become established in new areas, spread and, eventually, invade. Here, using ...
Pollination Syndromes: A Global Pattern of Convergent Evolution Driven by the Most Effective Pollinator
(Springer, 2015)
Convergent evolution of floral traits driven by pollinators has resulted in fl oral syndromes shared among different plant lineages. However, the flowers of many plant species are often visited by different pollinator groups, ...
