Photoprotection in the lichen Parmelia sulcata: the origins of desiccation-induced fluorescence quenching.

Lichens, a symbiotic relationship between a fungus (mycobiont) and a photosynthetic green algae or cyanobacteria (photobiont), belong to an elite group of survivalist organisms termed resurrection species. When lichens are desiccated, they are photosynthetically inactive, but upon rehydration they can perform photosynthesis within seconds. Desiccation is correlated with both a loss of variable chlorophyll a fluorescence and a decrease in overall fluorescence yield.

Educational technology transfer in newly independent states: developing a medical multimedia laboratory in Lithuania.

This paper discusses the development of an interactive multimedia computer laboratory within the Vilnius University Medical Faculty involving transfer of hardware and courseware developed in the USA. The contexts in which the laboratory was developed are described and factors helping and hindering successful technology transfer are identified. The future of the laboratory and its potential role in international distance education and information access are discussed.
