Metabolic recovery of continental antarctic cryptogams after winter

  title={Metabolic recovery of continental antarctic cryptogams after winter},
  author={Mark Schlensog and Stefan Pannewitz and Thomas George Allan Green and Burkhard Schroeter},
  journal={Polar Biology},
The activation of metabolism after the winter period was investigated in several mosses and lichens in continental Antarctica. Thalli that were still in their over-wintering inactive state in early spring were sprayed artificially and the time-dependent activation of photosystem II (PSII), carbon fixation and respiration was determined using gas exchange and chlorophyll a fluorescence techniques. The investigated lichens recovered PSII activity almost completely within the first few minutes and… CONTINUE READING
