Congratulations to former lab members Anthony Vaudo and Emily Erickson - their collaborative paper with Junpeng Mu (who was a visiting scientist in our lab) is published in Scientific Reports! Vaudo, A. D., Erickson, E., Patch, H. M., Grozinger, C. M., and Mu, J. “Impacts of soil nutrition on floral traits, pollinator attraction, and fitness in cucumbers (Cucumis sativus l.)” Scientific Reports:

Annual plants allocate soil nutrients to floral display and pollinator rewards to ensure pollination success in a single season. Nitrogen and phosphorus are critical soil nutrients whose levels are altered by intensive land use that may affect plants’ fitness via pollinator attractiveness through ...
