| Sumario: | 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. |
