Eunotia (Bacillariophyceae) from a subtropical stream adjacent to Iguaçu National Park, Brazil, with the proposition of a new species

A new species of the diatom genus Eunotia, named Eunotia caniculoides sp. nov., was discovered in a subtropical stream adjacent to Iguaçu National Park, Brazil. This finding adds to the biodiversity of the region and expands the known diversity of Eunotia taxa. The study also documented eight new records for Paraná state, contributing to the understanding of diatom distribution in this UNESCO World Heritage Site. Researchers analyzed periphytic material collected monthly from September 2012 to August 2013 using light and scanning electron microscopy. This systematic analysis highlights the importance of microalgal studies in conservation efforts and ecological assessments.
