Assessing the role of dispersed floralresources for managed bees in providingsupporting ecosystem services for croppollination [PDF]
, 2018 Most pollination ecosystem services studies have focussed on wild pollinators and their dependence on natural floral resources adjacent to crop fields. However, managed pollinators depend on a mixture of floral resources that are spatially separated from

Combined stress from parasites, pesticides and lack of flowers drives bee declines [PDF]
, 2015 Bees are subject to numerous pressures in the modern world. The abundance and diversity of flowers has declined, bees are chronically exposed to cocktails of agrochemicals, and they are simultaneously exposed to novel parasites accidentally spread by ...

Pollination of Nypa fruticans (Wurmb.) in a South Florida botanic garden
Journal of Pollination Ecology, 2021 When plants are removed from their native habitat, reproduction can be compromised if pollinators are absent, especially when plant-pollinator interactions are species-specific and the plant is self-incompatible.

Agriculturally dominated landscapes reduce bee phylogenetic diversity and pollination services
Science, 2019 Ancestral history matters Biodiversity is sometimes quantified purely by the number of species within a system that allow it to function to produce ecosystem services. Grab et al. show that simple species counting is too simplistic.

Reproductive success through high pollinator visitation rates despite self incompatibility in an endangered wallflower [PDF]
, 2016 PREMISE OF THE STUDY: Self incompatibility (SI) in rare plants presents a unique challenge—SI protects plants from inbreeding depression, but requires a sufficient number of mates and xenogamous pollination. Does SI persist in an endangered polyploid? Is

Pollination ecology and breeding system of two Calceolaria species in Chile [PDF]
, 2014 Indexación: Web of Science; Scielo.Many angiosperms are exclusively dependent on pollinators for its reproduction (Matallana et al.2010; Arroyo et al. 2006).

The Indian Journal of Agricultural Sciences, 2014 Due to lack of stable male sterile system in okra [Abelmoschus esculentus (L.) Moench], hybrid seed production is still dependant on hand emasculation and pollination which is troublesome and labour intensive. Five hybridization techniques, viz.

Ecology and Evolution, 2023 Reproductive isolation plays an important role in maintaining the species integrity of sympatric close relatives. For sympatric Arisaema species, interspecific gene flow is expected to be effectively prevented by pre‐pollination barriers, particularly ...

Floristic response to urbanization: Filtering of the bioregional flora in Indianapolis, Indiana, USA [PDF]
, 2017 PREMISE OF THE STUDY: Globally, urban plant populations are becoming increasingly important, as these plants play a vital role in ameliorating effects of ecosystem disturbance and climate change.

Nature Communications, 2019 How insects promote crop pollination remains poorly understood in terms of the contribution of functional trait differences between species. We used meta-analyses to test for correlations between community abundance, species richness and functional trait
