Have you ever thought about all those diverse pollinators you see foraging on flowers? Have you ever considered them as important vectors of floral microbes? Well, they are! Community ecologist Ash Zemenick, formerly in the graduate student program of...

You're watching honey bees foraging in a field. They buzz toward a blossom, sip nectar, and then head for another blossom. Typical, right? But there's much more going on than you think. It's not just the nectar that she's scented. UC Davis...
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.

It's surprising what the microbes in nectar can reveal. Take the nectar of the sticky monkeyflower, Mimulus auranticus. UC Davis community ecologist Rachel Vannette and colleague Tadashi Fukami of Stanford University decided to examine microbial...
