Panicle inclination influences pollination stability of rice (Oryza sativa L.)
Plant Production Science, 2020 Rice pollination occurs when pollen grains fall by gravity from the anther onto the stigma and has been thought to be assured under suitable conditions. However, the position of the stigma relative to the anther pores may affect pollination.

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

Characterizing the floral resources of a North American metropolis using a honey bee foraging assay
Ecosphere, 2020 Roughly a third of described insect species visit flowers, making the flower–insect interface one of the chief pillars of global biodiversity. Studying flower–insect relationships at the scale of communities and landscapes has been hindered, however, by ...

The limits of mean-field heterozygosity estimates under spatial extension in simulated plant populations [PDF]
, 2012 Computational models of evolutionary processes are increasingly required to incorporate multiple and diverse sources of data. A popular feature to include in population genetics models is spatial extension, which reflects more accurately natural ...

Movement of soil-applied imidacloprid and thiamethoxam into nectar and pollen of squash (Cucurbita pepo). [PDF]
PLoS ONE, 2012 There has been recent interest in the threat to bees posed by the use of systemic insecticides. One concern is that systemic insecticides may translocate from the soil into pollen and nectar of plants, where they would be ingested by pollinators.
