Moss-inhabiting diatom communities from Heard Island, sub-Antarctic
In this paper, we list 192 diatom taxa, collected from bryophyte samples from Heard Island (52degrees05'S, 73degrees30'E). The Heard Island diatom flora shows a marked similarity to those of the Crozet and Kerguelen archipelagos, and is quite dissimilar to the moss-dwelling diatom flora of...
