Revision of the genus Hantzschia (Bacillariophyceae) on Livingston Island (South Shetland Islands, Southern Atlantic Ocean)
Background and aims – The non-marine diatom flora of Livingston Island (South Shetland Islands, Maritime Antarctic Region) is currently under revision. One of the genera that still needed a revision is the genus Hantzschia , quite common in terrestrial habitats of the Antarctic Region. Methods – Usi...

One of the genera that still needed a revision is the genus Hantzschia , quite common in terrestrial habitats of the Antarctic Region.
