The seasonal periodicity of algae on Antarctic fellfield soils
Investigation of the seasonal changes in composition of an immature Antarctic fellfield cyanobacterial/microalgal community has demonstrated a repeated periodicity. The community consisted of only 14 species. Early spring growth of filamentous chlorophytes under snow and ice was followed by summer d...

Investigation of the seasonal changes in composition of an immature Antarctic fellfield cyanobacterial/microalgal community has demonstrated a repeated periodicity. The community consisted of only 14 species. Early spring growth of filamentous chlorophytes under snow and ice was followed by summer dominance of the community by cyanobacteria, particularly Phormidium autumnale. Limitation of the chlorophyte populations appeared to be a result of either dehydration of the soil or increased irradiance. The population maximum of the cyanobacteria occurred in mid-summer, although there were no obvious reasons for the cessation of growth at this time, and declined rapidly in late summer. Regrowth of the community occurred from very small inocula each spring, most of the biomass having been lost during late summer or during the washout associated with the spring thaw. This regrowth demonstrates the potential for the population to establish an immature fellfield community very rapidly foliowing exposure by glacial retreat or physical disturbance. |
