NITROGEN FIXATION BY LICHENS ON GLACIAL DRIFT IN ICELAND
Summary Species of Peltigera Willd. and Stereocaulon Schreb. are among the most abundant macrolichens in the developing and older Rhacomitrium heaths on glacial drift at Sólheimajökull. The crustaceous Placopsisgelida (L.) Linds. is also a common pioneer lichen on rocks. These species contain a blue...
