AB Alnus pollen has been frequently detected in the atmosphere of different airborne sampling sites of Southern Spain. However,Alnus sp. populations are very scarce and fragmented in the area, being restricted to a few river valleys in the southwest, and otherfurther away regions of the Iberian Peninsula. This leads to think that the airborne pollen detected could be mainly the result of amedium- or long-distant transport. So, the aim of this study was to characterize the annual patterns of airborne Alnus pollendetected at three different locations of Malaga province, as well as to determine its possible origin, the pollen dispersion potentialof these Alnus isolated populations, and their possible reproductive connectivity. Pollen sampling was conducted by means ofthree Hirst-type volumetric pollen traps. Samples were mounted and counted following the recommendations of the SpanishAerobiology Network and the European Aeroallergen Society. The possible pollen sources were detected by means of acombination of meteorological information and backward air trajectories analysis. A high inter-annual variability in the annualpollen integrals was found in all the stations, favouring certain meteorological conditions a long-range transport and, therefore,causing the high concentrations detected in some specific days. Alnus pollen seems to have a heterogeneous origin withprevalence of the long-distant transport, which would suggest a possible reproductive connection among distant populations.
