What Attracts Bees to Blossoms? A Surprising Discovery by UC Davis Ecologist Rachel Vannette

A honey bee heads toward a lupine blossom. It's not just the nectar she's scented. UC Davis community ecologist Rachel Vannette has just published a paper in New Phytologist journal that shows nectar-living microbes release scents or volatile compounds, too, and can influence a pollinator's foraging preference.
