PollerGEN, an interdisciplinary group of researchers based in the United Kingdom, has published findings in Nature Ecology & Evolution, indicating that the species of grass pollen may have more impact than total pollen count on people who are affected by grass allergies.
The scientists also have found that the composition of airborne pollen is not a haphazard mix of various grasses. Instead, it “resembles a seasonal progression of diversity, featuring early, then mid- and late-season flowering grasses,” according to Simon Creer, a professor in molecular ecology and Georgina Brennan, a postdoctoral research officer, both from Bangor University.
