Latest Tundra Stories
According to research from Lund University in Sweden, the widespread reduction of ice in the Arctic Ocean has disrupted the balance of greenhouse gases in the region.
Researchers studying Arctic thermokarst failures in Alaska were alarmed to find climate-warming carbon dioxide gas may be releasing into the atmosphere at an unprecedented rate.
Scientists have known that climate change affects the population dynamics of single species, such as reindeer or caribou, but the effects of such climate change at the community level have been much harder to document and quantify.
New research shows that the breeding population of chinstrap penguins has significantly declined as temperatures have increased on the Antarctic Peninsula.
Carbon stored in Arctic tundra could be released into the atmosphere by new trees growing in the warmer region, exacerbating climate change, scientists have revealed.
An international team of scientists have published the first continent-wide assessment of the Antarctic's biogeography, and propose that the landmass should be divided into 15 distinct conservation regions to protect the continent from invasive alien species.
Plants and shrubs in the Arctic tundra have turned into small trees in recent decades due to the warming Arctic climate. If the trend continues on a wider scale, it would significantly accelerate global warming.
A series of papers published this month on ecological changes at 26 global research sites -- including one administered by the University of Colorado Boulder in the high mountains west of the city -- indicates that ecosystems dependent on seasonal snow and ice are the most sensitive to changes in climate.
Freshwater ecosystems in northern regions are home to significantly more species of water fleas than traditionally thought, adding to evidence that regions with vanishing waters contain unique animal life.
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...
Antarctica is the Earths southernmost continent; it contains the geographic South Pole. It’s situated in the Antarctic area of the Southern Hemisphere, almost completely south of the Antarctic Circle, and is bordered by the Southern Ocean. It’s the fifth-largest continent at 5.4 million sq miles. On average, it is the driest, coldest, and windiest continent as well as having the highest average elevation of all the continents. Considered a desert, the annual precipitation is only 8...
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,...
