Resumen:
Summary: Pollen deposition in Taubertraps and surface soil samples in the Mar Chiquita coastal lagoon
area, pampa grasslands (Argentina).
Estimations of airborne pollen loadings deposited in Tauber traps were studied in a coastal lagoon from
south-eastern Pampa grasslands, Argentina, in order to assess their relationship with surface samples
and to interpret the representativeness of local, regional and extraregional vegetation. Three different
environments were considered: a coastal dune barrier with a psammophytic community, a salt marsh
with a halophytic community in Mar Chiquita lagoon, and a freshwater community at Hinojales freshwater
lake. Based on a record of surface samples taken from a previous paper, a parametric model was built
to classify Tauber samples gathered from the natural vegetation communities of the study area. Results
revealed that just like their surface counterparts, Tauber trap records qualitatively reflect the predominant
vegetation types, although ecological groups feature different quantitative representations depending on
the record type. Pollen loadings showed that airborne pollen transport was predominantly of local range,
in accordance with previous results from the same study area. Airborne surface samples relationships
enrich our knowledge of the present environment that could be useful to improve paleoecological
interpretations of the areaPollen deposition in Taubertraps and surface soil samples in the Mar Chiquita coastal lagoon
