Název v původním jazyce

Response of cyanobacteria and algae from Antarctic wetland habitats to freezing and desiccation stress

Popis výsledku v původním jazyce

Vigor, after freezing and desiccation, was laboratory tested in cyanobacteria and algae strains from wetland habitats collected in maritime and continental Antarctica. Whereas minor sub-zero temperatures (-4°C), demonstrating summer diurnal freeze-thaw did not cause significant damage on either cyanobacteria and algae, low sub-zero temperatures(-40, -100, -196°C), demonstrating annual winter freeze, caused little harm to cyanobacteria, but was fatal for more than 50% of the population of algae. Freezingand desiccation tolerance of these strains was compared using multiregression methods: cyanobacteria from continental Antarctica were significantly more tolerant to low sub-zero temperatures than similar strains from maritime Antarctica (P = 0.026; F =3.66); and cyanobacteria from seepages habitat were less tolerant to freezing and desiccation than cyanobacteria from other wetlands (P = 0.002; F = 5.69).
