The accepted theory has been that algae adapted to a place help their fungal partners to increase their ecological range. However, this experiment was able to show that the reverse can also be true. The fungus can help algae by boosting their carbon fixing ability. Rocks are heated and retain...

When an asteroid smacked into the Earth 66 million years ago, it triggered mass extinctions all over the planet. The most famous victims were the dinosaurs, but early birds, insects, and other life forms took a hit too. The collision caused clouds of ash to block the sun and cool the pl...

A classic example of symbiosis, lichens have long been known to be the result of a mutually beneficial relationship betweenfungiand algae. "With the microscopy, we could visualize the mosaic of different organisms within thelichen," said Tuovinen, who completed her Ph.D. at Uppsala University. ...
A chemical secreted by the fungus softens the cell walls of the algae and allows nutrients to pass from the algae to the fungus. There are many examples of symbiosis in nature, but lichens are unique because they look and behave differently from their components. The algal components of ...
Lichens are curious organisms comprising a stable symbiosis between a fungus and one or morephotosynthetic organisms, for example green algae and/or cyanobacteria. Once the symbiosis is established, the new composite organism starts to function as a whole new one, which can now convert sunlight into...
In the end of the nineteenth and early twentieth century, by discovering “symbiosis” as a common strategy of life, lichens were recognized to have a double nature and found to be composed of “a fungus and algae/cyanobacteria” (e.g., Schwendener, 1869). Page %P Close Plain text ...

When isolated in pure culture, four genera of lichen algae were able to produce the polyol which is known to move from the alga to the fungus in lichens with these algae. This conclusion corrects earlier suggestions that the mobile polyol is only formed by the alga in the lichen thallus. ...
