MICRO-INVERTEBRATE COMMUNITY STRUCTURE WITHIN A MARITIME ANTARCTIC LAKE
Abstract: The data set discussed here was obtained from a transect across a depth profile in Sombre Lake (Signy Island, South Orkney Islands). The fauna, composed of benthonic micro-invertebrates, was readily observed grazing on the surface of the cyanobacterial mats that form a thin cover on the su...
