Dr. Yolanda Wiersma, a landscape ecologist in the Department of Biology, Faculty of Science, and Dr. Troy McMullin, a lichenologist at the Canadian Museum of Nature, are proposing a lichen-focused system in a paper published in the Ecological Society of America journal, Frontiers in Ecology and the Environment.
Lichens are found on every continent and grow in all climates – from polar regions to harsh deserts.
A symbiotic association between different organisms, lichen can be part fungus and part green alga or a cyanobacterium, or both, and are sensitive bioindicators of environmental change.
