In our new Biology Letters paper, Felicity, Jake and I showed that bees responded differently to pollen blends adulterated with a sweet (sucrose) or bitter (quinine) substance. The taste of pollen affected how much of it bees collected from a flower, as well as their tendency to land subsequently on a visually-similar flower. We're excited about the implications of these findings for looking at pollen chemistry in a new light! This was also a fun chance to use our thermal camera :)

Our NSF collaboration with colleagues at the University of Arizona (PhD Student Avery Russell, co-PI Dan Papaj and undergraduate Rebekah Golden) has produced a new paper in Behavioral Ecology, involving a first-of-its-kind experiment that explores what floral features bees learn from plants that reward bees with pollen alone. Avery pioneered the "frankenflower" design, which allows him to compare the responses of naive and experienced bees to flowers that have anthers matched or mismatched between Solanum and Exacum plants. Check it out on ResearchGate, or via the journal website. Congrats Avery!!
We're excited about our new publication, "Colour learning when foraging for nectar and pollen: bees learn two colours at once" out today in Biology Letters. It was a fun experience to prepare a short-format manuscript, and Felicity's experiment uncovered some exciting findings about basic aspects of bee foraging.
When most people think about bee learning, they think of sugary nectar rewards. However, many bees collect both nectar and pollen (their source of protein) on a foraging trip. Felicity was interested in the cognitive aspects of this "multitasking". At least here when the rewards are on different flowers, bees can indeed learn to associate color + reward type. Doing so may come at a cost, as we found some evidence that bees focusing on a single reward performed better (more on that in forthcoming publications).
From the plant POV, it's interesting that bees seem to form expectations about what kind of reward a plant will offer based on its color. Could this have consequences for co-flowering plant species?
