The nitrogen fixing biota of Macquarie Island are dominated by cyanobacteria growing epiphytically or symbiotically with plants or lichens. Highest rates of acetylene reduction (N-fixation) were found in the leafy lichen Peltigera sp. Colonising herbfields and short grasslands, and in the coastal an...
