New records of Cosmarium Corda ex Ralfs in lotic environment, adjacent to the Iguaçu National Park, Paraná State, Brazil

A taxonomic inventory of Cosmarium (Desmiadiales, Zygnematophyceae) in a subtropical stream adjacent to Iguaçu National Park, Paraná State, Brazil, revealed 37 taxa, including 15 new records for the state. These discoveries expand the known biodiversity of the region, contributing valuable data to conservation efforts at this UNESCO World Heritage Site. The study employed monthly sampling of periphytic material associated with Eleocharis minima Kunth from August 2012 to July 2013, providing a comprehensive baseline for future ecological research.
