Description
  • Diurnal courses of photosystem II (PS II) activity of Xanthoria elegans were continuously monitored using a novel technique of chlorophyll fluorescence imaging in the field (maritime Antarctica) over a period of 7 days. The lichen specimens grew on stone surfaces in a North-facing coastal area of Galindez Island (Argentine Islands). A portable fluorometer FluorCam equipped with a CCD camera and image analysis software was placed over a thallus so that false color images of FV/FM and quantum yield of photochemical processes in PS II (śII) distribution over the thallus could be taken in the course of a day. Simultaneously, microclimatic parameters of the habitat were recorded: air and thallus temperature, relative air humidity, PAR (photosynthetically active radiation) and global radiation. Photosynthetic processes in X. elegans were activated by rainfall or water from melting snow.
