Phytoplankton in the RAMSAR site “Esteros del Iberá” (Argentina): A comparison between drought and flood years

This study analyzes the abundance, diversity, species richness, and evenness of phytoplankton in the Esteros del Iberá (Argentina) under two contrasting climatic conditions, encompassing both lentic and lotic environments. Analyses revealed that phytoplankton abundance in most of the Iberá system en...

Cyanobacteria diversidad floraciones algales invasoras This study analyzes the abundance, diversity, species richness, and evenness of phytoplankton in the Esteros del Iberá (Argentina) under two contrasting climatic conditions, encompassing both lentic and lotic environments. Analyses revealed that phytoplankton abundance in most of the Iberá system environments is unaffected by climatic variability; however, diversity, species richness, and evenness of phytoplankton were modified. In the large shallow lakes, Cyanobacteria predominated as components of the phytoplankton, with the highest density values in lagoon Iberá during the dry period. Two of the cyanobacteria species identified (Raphidiopsis raciborskii y Microcystis aeruginosa) are bloom-forming and potential producers of cyanotoxins, thus early detection of harmful species and sustainable management actions are recommended for tourist and conservation activities. En este estudio se analiza la abundancia, diversidad, riqueza de especies y equitatividad del fitoplancton en los Esteros del Iberá (Argentina), en dos condiciones climáticas contrastantes, tanto para ambientes leníticos y lóticos. Los análisis mostraron que la abundancia del fitoplancton en la mayoría de los ambientes del sistema Iberá no es afectada por la variabilidad climática; sin embargo, si se ve modificada la diversidad, riqueza de especies y equitatividad del fitoplancton. En las grandes lagunas predominan las cianobacterias como componentes del fitoplancton, con los valores más altos de densidad en la laguna Iberá durante el período seco. Dos de las especies encontradas de cianobacterias (Raphidiopsis raciborskii y Microcystis aeruginosa) son formadoras de floraciones y potenciales productoras de cianotoxinas, por lo que se recomienda acciones de monitoreo de vigilancia para estas especies y manejo sustentable para las actividades turísticas y de conservación.
