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...

Norway's Rainforests Hidden Secrets
2012-07-18 09:44:57

The word rainforest usually conjures up visions of brightly colored birds and hyperactive monkeys swooping through a thick green canopy of leaves, vines and flowers.  But rainforests are also found closer to the poles, in the northern or boreal region where temperatures are far cooler. And while there are no monkeys swinging through the trees here, these forests are every bit as endangered as their southern cousins, and highly diverse — if you know where to look. Olga Hilmo...

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...

Lichen study has implications for ecosystem researchLichens are the classic example of a symbiotic relationship. Both the fungal and photobiont components of the lichen benefit from the relationship and often are unable to survive without each other. Recent research by Dr. Robert Lcking (The Field Museum, Chicago), Dr. James Lawrey (George Mason University, Virginia) and a team of colleagues from around the world has put a new spin on this relationship.In a paper published in the August 2009...

By Hagadone, Zach With help from a National Science Foundation grant, a Kimberly- based company is researching new methods of arid land restoration that it hopes may help bring back to life thousands of acres of wildfire-ravaged and overused soil around the state. Conservation Seeding & Restoration, Inc. received the $98,215 award from the foundation's Small Business Innovation Research (SBIR) program, and intends to use it for phase one of a feasibility study into spray-on biological...

ESA -- One of the main focuses in the search for living organisms on other planets and the possibilities for transfer of life between planets currently centres on bacteria, due to the organisms simplicity and the possibility of it surviving an interplanetary journey exposed to the harsh space environment. This focus may develop to encompass more advanced organisms following the results of an ESA experiment on the recent Foton-M2 mission where it was discovered that lichens are very adept at...

Reindeer Moss, Cladonia rangiferina
2005-06-02 10:18:18

Reindeer moss is a moss belonging to the family Cladoniaceae. It grows in both temperate and cold climate areas. It has had great economical importance, since it is the main fodder for reindeers. It can also be used in the making of aquavit and is sometimes used as decoration in glass windows. Reindeer moss is actually another name for reindeer lichen. This lichen is found in the Alpine tundra and can survive in the cold. Image Caption: Reindeer Moss photographed in White Oak Mountain,...
