ScienceDaily -- ScienceDaily (Mar. 18, 2011) — Researchers from the University of Extremadura (Spain) have shown that the pollen levels of certain plants, such as grasses and cupressaceae, can appear before or after the peak moment of flowering. This phenomenon is caused by the “resuspension” of pollen, and its dispersal over large distances, and this is of great use in predicting allergies.
