SOME PHOTOSYNTHETIC FEATURES OF DESICCATION-TOLERANT TERRICOLOUS LICHEN AND MOSS SPECIES TRANSPLANTED TO A NATURAL CO2VENTS: PRELIMINARY COMMUNICATION

This work’s aim is predict the photosynthetic responses of forest floor cryptogam species to elevated atmospheric CO2level. The study was carried out at the natural CO2spring of Lajatico (Toscana). We compared the photosynthetic behaviour of sixin situgrowing indigenous moss species, and further 2-2 one-over-one transplanted moss (from different habitat) and native lichen species at CO2spring to control site. This study suggested that the long-term adjustment of photosynthetic capacity to elevated atmospheric CO2may be diverse and strongly species dependent.
