Environmental behaviour of airborne Amaranthaceae pollen in the southern part of the Iberian Peninsula, and its role in future climate scenarios

Abstract

• A 21-year-set of Amaranthaceae pollen records was analysed to chart environmental reaction. • Rainfall and maximum temperatures were the parameters more related to the Pollen Index. • Amaranthaceae species have a rapid response to scarce water availability. • Amaranthaceae pollen will have a greater impact on future scenarios for pollen allergy. a b s t r a c
