Ferocia gen. nov., a new centric diatom genus (Bacillariophyceae) from the sub-Antarctic region
International audience A new centric diatom genus, Ferocia Van de Vijver and Houk gen. nov. is described based on Melosira setosa Greville. Several samples collected in lava tunnels on Ile Amsterdam, a small isolated, volcanic island in the southern Indian Ocean where the latter taxon dominated the...
