The increase in temperature in the Arctic has already caused the sea-ice there to melt. According to research conducted by the University of Gothenburg, if the Arctic tundra also melts, vast amounts of organic material will be carried by the rivers straight into the Arctic Ocean, resulting in additional emissions of carbon dioxide. Several Russian rivers enter the Arctic Ocean particularly in the Laptev Sea north of Siberia. One of the main rivers flowing into the Laptev Sea is the Lena,...

Much of circumpolar Arctic research focuses on the physical, direct changes resulting from climate warming such as sea ice retreat and temperature increases. "What's understudied is the living component of the Arctic and that includes humans," said Syndonia "Donie" Bret-Harte, associate professor of biology at the University of Alaska Fairbanks and co-author of a paper to be published September 11, 2009 in the journal Science. The paper reviews current knowledge on the ecological consequences...

Researchers conduct fieldwork to track permafrost melting in Alaska and gain insight about the release of carbon into the atmosphereThe terrain of the North Slope of Alaska is not steep, but Andrew Jacobson still has difficulty as he hikes along the spongy tundra, which is riddled with rocks and masks multitudes of mosquitoes.Jacobson, a professor of earth and planetary sciences at Northwestern University, extracts soil and water samples in search of clues to one of global warming's biggest...

"I wonder if I shall fall right through the Earth!" mused Alice-in-Wonderland as she tumbled down the rabbit-hole." How funny it'll seem to come out among people that walk with their heads downwards! The antipathies, I think ..."Alice's experiences in a below-ground world, written about by Lewis Carroll in 1865 in his famed Alice's Adventures in Wonderland, were fiction.Or were they?If the work of biologist Diana Wall of Colorado State University (CSU) in Fort Collins is any indication, life...

As frozen arctic soil thaws due to climate change, U.S. scientists say bacteria will break down large amounts of carbon, sending it into the atmosphere. Although plants will initially proliferate, nurtured by balmier conditions and an increasing abundance of the greenhouse gas they depend on for growth, University of Florida researchers said they don't expect plant growth will be able to blunt the carbon release. At first, with the plants offsetting the carbon dioxide, it will appear...

Ancestors of tapirs and ancient cousins of rhinos living above the Arctic Circle 53 million years ago endured six months of darkness each year in a far milder climate than today that featured lush, swampy forests, according to a new study led by the University of Colorado at Boulder. CU-Boulder Assistant Professor Jaelyn Eberle said the study shows several varieties of prehistoric mammals as heavy as 1,000 pounds each lived on what is today Ellesmere Island near Greenland on a summer diet of...

"A slow-motion time bomb." That's what one ecologist calls the looming threat of trapped greenhouse gases in the melting Arctic. Ted Schuur, an ecologist from the University of Florida, says the impact of thawing Arctic soil would allow bacteria to slowly break down organic matter and release carbon into the atmosphere, further exacerbating global warming. However, plants will also began to grow more as a result of thawing, which causes researchers to question how much these shrubs will be...

Taiga, or otherwise known as boreal forest, is a biome that is characterized by coniferous forests made up mostly of spruces, larches, and pines. The taiga is the world’s largest terrestrial biome. In North America, it covers most of inland Canada and Alaska as well as portions of the extreme northern continental United States and is known as the Northwoods. It covers most of Sweden, Finland, much of Norway, lowland/coastal areas of Iceland, much of Russia, northern Kazakhstan, northern...

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,...
