Revision of the genus **Eunotia** (Bacillariophyta) in the Antarctic Region
Abstract: Background and aims The past few years, the limnoterrestrial and aquatic diatom flora of the entire Antarctic Region (sub-Antarctic islands, Maritime Antarctic Region, Antarctic Continent) is currently under revision. One of the genera that still needed a revision is the genus Eunotia, qui...
