research bits: ‘Lichen is a symbiosis, two or more organisms living together such that both are more successful within the partnership than they would have been if they were living on their own. There are about 13,500 species of lichen, occurring in some of the most extreme environments on Earth. Lichens are widespread and may be long-lived; however, many species are also vulnerable to environmental disturbance,
and may be useful to scientists in assessing the effects of air pollution, ozone depletion, and metal contamination.’
