Flexible Partnership Lets Lichens Live In Different Habitats
2013-04-23 15:40:42

Pensoft Publishers Lichens are symbiotic organisms consisting of a fungal partner and one or several algal partners. The association is so close that scientists until 1867 were not aware that lichens actually consist of two different partners. After the Swiss botanist Simon Schwendener discovered the dual nature of lichens, lichenologists were focusing on the fungal partner when studying lichens, since it was often believed that only few algae are involved in the symbiosis. Molecular...

Lichen, those drab, fuzzy growths found on rocks and trees, aren't as cuddly and charismatic as kangaroos or intriguing as opossums, but they could be a fungal equivalent, at least evolutionarily. A Duke research team has found that lichen that seem identical in all outward appearances and produce the same internal chemicals are in fact two different species, one living in North America and one in Australia. They're an example of "convergent evolution," in which two species evolve separately...

But the lichen is so rare it may never be seen again A Philadelphia botanist who has studied rare plants for 50 years, but has never attained the honor of having a plant named for him is finally getting his due, but with a barely visible organism so rare it may never be seen again. Dr. Alfred "Ernie" Schuyler, emeritus curator of botany at the Academy of Natural Sciences and a world expert on rare plants, recently was honored when a colleague discovered a new species of lichen and named it...

A signature of undiscovered global diversity In an unprecedented coming-out party, 100 newly discovered species are revealed to the world in a single scholarly paper coordinated by Field Museum scientists. The 100 organisms are lichens, a type of fungi that form associations with algae and populate environments from arctic tundra to tropical rain forests. And the usual inattention bestowed upon new lichens is one reason for aggregating so many new ones in a single paper in the Feb. 18 issue...

Spanish scientists have described the lichen Phylloblastia fortuita, new to the Iberian Peninsula and to science. Another species from the same family, Phylloblastia dispersa, is also a new entry for Europe and is the first time it has been found outside the tropics. Foliicolous lichens, symbiosis between fungi and algae, are organisms associated with tropical or sub-tropical climates, and their presence in environments such as the Iberian Peninsula, outside of the tropics, is associated with...
