Resumo: The eight samples from the surface sediments of intertidal marshes on the margin of the Patos Lagoon Estuary were studied by palynological analysis. Pollen and spores of vascular terrestrial and aquatic plants were identified and compared with present vegetation cover of intertidal marshes in order to establish the relationship between pollen-and-spore assemblages and the vegetation cover. The recognized pollen-and-spore assemblages generally coincide with the currently existing vegetation in the intertidal marshes, but show a higher diversity. Other observed palynomorphs include: zygospores and colonies of freshwater chlorococcales, cysts of acritarchs and dinoflagellates, fungal spores, and microforaminiferal linings. Marine algae cysts are a distinguishable characteristic of palynomorph assemblage from surface sediments of intertidal marshes. The anthropogenic impact on this region is emphasized by pollen of introduced plants, such as, Pinus, Eucalyptus, and others.

A composição taxonômica de pólen e esporos identificados foi comparada com cobertura vegetal de marismas atuais para estabelecer a correspondência de dados palinológicos e vegetação atual de marismas. Outros palinomorfos encontrados incluem zigosporos e cistos de algas de água doce e marinha, esporos de fungos e invólucros de microforaminiferos. O impacto antrópico nesta região é expresso pelo pólen de plantas introduzidas tais como Pinus, Eucalyptus, e outros.Iheringia.
