The genus Pinnularia (Bacillariophyta) on Ile Amsterdam (TAAF, Southern Indian Ocean)
International audience Ile Amsterdam (77° 34′ E, 37° 47′ S), a young, small volcanic island situated in the southern Indian Ocean has a very isolated geographic position and is one of the remotest places in the world. The geographic and physical features of the island have resulted in the presence o...
