Resumen
Modern pollen deposition and its relationship to the surrounding vegetation were studied at a coastal lagoon from the southeast of Buenos Aires Province (Argentina). Tauber traps were monitored monthly over a 2-year period in a coastal dune barrier, salt marsh and continental freshwater lake. Pollen deposition exhibited seasonal patterns with maximum values during summer and a spatial variability of increasing deposition from the coast to inland sites. The pollen spectra suggest that airborne pollen originates mainly from local vegetation with scarce representation of extraregional sources. Herbaceous pollen predominates, comprising up to 90% of the total amount with Poaceae, Chenopodiineae and Asteroideae as the main types. Hydrophytic, psammophytic and extraregional types had little influence on the pollen spectra, generally comprising 5% of the total pollen. Pollen influx–vegetation abundance discrepancies were explained considering pollination syndrome, spatial distribution and structure of vegetation.
