Rhizocarpon geographicum (the map lichen) is a species of lichen, which grows on rocks in mountainous areas of low air pollution. Each lichen is a flat patch bordered by a black line of fungal hyphae. These patches grow adjacent to each other, leading to the appearance of a map or a patchwork field.
Bacidina pycnidiata is a pioneer species that grows over bryophytes, both terrestrial and epiphytic. Habitats include both old-growth and managed forests , and anthropogenic areas. Occasionally the lichen has been recorded on tree bark in shaded areas, or growing on other lichens, [ 3 ] as was the case with Caucasian specimens found growing on ...
The fungi of some lichen species may "take over" the algae of other lichen species. [16] [135] Lichens make their own food from their photosynthetic parts and by absorbing minerals from the environment. [16] Lichens growing on leaves may have the appearance of being parasites on the leaves, but they are not.
The map lichen (Rhizocarpon geographicum), the lichen most used in lichenometry. Lichenometry can provide dates for glacial deposits in tundra environments, lake level changes, glacial moraines, trim lines, palaeofloods, [9] rockfalls, seismic events associated with the rockfalls, [2] talus stabilization and former extent of permafrost or very persistent snow cover.

After a natural disaster, common pioneer organisms include lichens and algae. Mosses usually follow lichens in colonization but cannot serve as pioneer organisms. These common pioneer organisms can have a preference in the temperatures they are in. Lichens are more inclined to be in regions with more rainfall, whereas algae and mosses have a preference of being in regions with more humidity.
In primary succession pioneer species like lichen, algae and fungi as well as abiotic factors like wind and water start to "normalise" the habitat or in other words start to develop soil and other important mechanisms for greater diversity to flourish. Primary succession begins on rock formations, such as volcanoes or mountains, or in a place ...
Enchylium limosum is a widely distributed lichen species with a holarctic range, occurring across temperate to boreal-montane regions of Europe, North America, Africa, and Asia. [ 7 ] [ 2 ] [ 22 ] Within Europe, the species has been recorded from a number of countries, including Italy , the United Kingdom , Ireland , the Czech Republic ...
Anaptychia ciliaris, commonly known as the great ciliated lichen or eagle's claws, is a species of fruticose lichen in the family Physciaceae. [2] It is predominantly found in Northern Europe, with its range extending to European Russia, the Caucasus, Central and Southern Europe, the Canary Islands, and parts of Asia.
