Abstract
The influence of positive and negative temperatures, as well as dehydration/rehydration on the maximum photochemical efficiency, the rate of electron transfer in photosystem II and non-photochemical quenching of the moss Hylocomium splendens, widespread in the boreal forests of the Northern Hemisphere, is shown. It was found that this moss is resistant to low negative (–20 and –80°C) temperatures and significant water losses. On the contrary, in the hydrated state it is unstable to prolonged exposure to positive temperatures (40°C). High resistance to low temperatures and dehydration allowed H. splendens to successfully adapt to growing in northern latitudes and occupy a wide range.
