Nitrogen fixing activity in lichens of Khibiny Mountains (Murmansk region).

摘要

The potential nitrogen fixing activity of herbarium and fresh specimens of lichens was studied. The herbarium specimens remained viable for one or three years. The nitrogen fixing activity of Peltigera aphthosa, P. leucophlebia and P. scabrosa is species specific, but that of P. canina is not. Dynamics of the potential nitrogen fixing activity of Solorina crocea was studied. This shows considerable nitrogen fixing activity during the growing season.
