Abstract
Algal mats comprised primarily of the blue-green algae (cyanobacteria) Phormidium frigidum and Lyngbya martensiana, several species of pennate diatoms and heterotrophic bacteria occur abundantly throughout much of the benthic regions of perennially ice-covered Lakes Bonney, Chad, Fryxell, Hoare, and Vanda, southern Victoria Land, Antarctica (77°32–43′S, 161°33′–1 63°07′E). The particular types of mats described include moat and pond mats, ice cover mats, in situ lift-off, pinnacle, aerobic prostrate and anaerobic prostrate mats. Variations in light, temperature, conductivity and oxygen between the five lakes and their in situ habitats explain many of the differences in algal species composition and mat morphology. A unique feature of many of the benthic mats is their development into modern cold freshwater stromatolites currently known nowhere else on earth.This publication has 3 references indexed in Scilit:
