This paper aims to determine the stage of the naturalization of ragweed (Ambrosia L.) in Catalonia, north-east Spain, and to analyze the airborne pollen pattern and provenance, in order to contribute to a better management of it and prevent the expansion of a possible new bioinvader that can also become a health problem due to its highly allergenic pollen. Biogeographical sampling consisted on the...
The Canary Islands, due to their geographical position, constitute an adequate site for the study of long-range pollen transport from the surrounding land masses. In this study, we analyzed airborne pollen counts at two sites: Santa Cruz de Tenerife (SCO), at sea level corresponding to the marine boundary layer (MBL), and Izaña at 2,367 m.a.s.l. corresponding to the free troposphere (FT), for the...
