Background and aims: Taxonomic works of the modern pollen grains from the vegetation of the Iberá Wetlands from northeastern Argentina, and other areas of the Corrientes province, have mostly been carried out in last decade. However, very few of these taxonomic works include illustration of palynomorphs. The objective of this contribution is to provide the first morphological records of palynomorphs of angiosperms, ferns, lycophytes and bryophytes from sediments from the Holocene of the Iberá Wetlands.
M&M: Core samples obtained by mean of a Livingston-type sampler from six lakes in their central and deepest parts on the western margin of the Iberá Wetlands were analyzed.
Results: Fifty-five types of palynomorphs are described and illustrated: 46 pollen types correspond to 27 families of angiosperms and nine trilete spore-types to ferns, lycophytes and bryophytes. Information to differentiate local (species that form part of the natural vegetation of the Iberá Wetlands) and extra-local taxa (those that do not belong to the Iberá), that achieved to depocenters mostly by means of wind currents coming from farther regional vegetation, was included.
Conclusions: Pollen grains and spores identifications up to species level enhances paleoenvironmental reconstructions based on more accurate ecologic information and geographical distribution. This work broadens the knowledge of the palynological flora of northeastern Argentina and it will contribute to differentiate the local vegetation from the extra-local in future paleocological and paleoenvironmental interpretations. |

Introducción y objetivos: Los trabajos taxonómicos de polen actual de la vegetación de los esteros del Iberá en el noreste de Argentina y otras áreas de la provincia de Corrientes se han llevaron a cabo mayoritariamente en la última década. Sin embargo, muy pocos de estos trabajos incluyen la ilustración de los palinomorfos. El objetivo de esta contribución es proporcionar el primer registro morfológico de palinomorfos de angiospermas, helechos, licofitas y briofitas de sedimentos del Holoceno de los Esteros del Iberá. M&M: Se analizaron muestras de núcleos obtenidos por medio de un muestreador tipo Livingston de seis lagos en sus partes central y más profunda en el margen occidental de los Esteros del Iberá. Resultados: Se describen e ilustran 55 tipos de palinomorfos: 46 tipos de polen corresponden a 27 familias de angiospermas y nueve tipos de esporas triletas a helechos, licofitas y briofitas. Se incluye información para diferenciar taxones locales (que forman parte de la vegetación natural de los Esteros del Iberá) y extra-locales (aquellos que no pertenecen al Iberá) que lograron llegar a los depocentros provenientes de vegetación regional más lejana. Conclusiones: La identificación de granos de polen y esporas hasta el nivel de especie mejora las reconstrucciones paleoambientales basadas sobre información ecológica y distribución geográfica más precisas. Este trabajo amplía el conocimiento de la flora palinológica del noreste de Argentina y contribuirá a diferenciar la vegetación local de la extra-local en futuras interpretaciones paleoecológicas y paleoambientales.
