Extreme Weather Events May Synchronize Entire Communities Of Species
2013-01-18 04:26:31

April Flowers for redOrbit.com - Your Universe Online 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. A new study from the Norwegian University of Science and Technology (NTNU) has found that extreme climate events cause a synchronized population fluctuation among all vertebrate species in a relatively...

Climate Change Affects Chinstrap Penguins In The Antarctic
2012-11-07 05:49:57

April Flowers for redOrbit.com - Your Universe Online New research, partially funded by the National Science Foundation (NSF), shows that the breeding population of chinstrap penguins has significantly declined as temperatures have increased on the Antarctic Peninsula. Changing climatic conditions, rather than the impact of tourism, has the greatest effect on the chinstrap population. The findings of this study, conducted by a research team with the Antarctic Site Inventory (ASI), have...

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. The Arctic is getting greener as plant growth increases in response to a warmer climate. This greater plant growth means more carbon is stored in the increasing biomass, so it was previously thought the greening would result in more carbon dioxide being taken up from the atmosphere, thus helping to reduce the rate of global...

Proposal follows first continent-wide survey of Antarctic biogeography 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. The team's findings are published in Diversity and Distributions, while the authors' proposals were outlined today at a lecture to the Antarctic Treaty...

Warming Arctic Climate Turns Shrubs To Forests
2012-06-05 03:52:51

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, said scientists from Finland and Oxford University in a new study published in the journal Nature Climate Change. The researchers investigated an area of 100,000 square kilometers from western Siberia to Finland known as the northwestern Eurasian tundra. Surveys of the area´s...

CU Research Shows Warming Climate Threatens Ecology At Mountain Research Site West Of Boulder
2012-04-19 07:42:15

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. The six papers appeared in the April issue of the journal BioScience. The papers were tied to data gathered at sites in North America, Puerto Rico, the island of Moorea near Tahiti, and...

Image 1 - Unexpected Crustacean Diversity In Northern Freshwater Ecosystems
2012-03-04 06:16:02

A new species adds to evidence that subarctic regions with vanishing waters contain unique aquatic animals 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. The new information on water fleas -- which are actually tiny crustaceans -- comes from a multi-year, international study that was published Feb. 24 in the journal Zootaxa....

The mention of lemmings usually evokes images of small rodents throwing themselves off the top of cliffs in acts of mass suicide; however, their reputations might no longer be determined by hearsay as a new report suggests they could be having an intricate effect on the Earth's climate. The study, published today, 18 November, in IOP Publishing's journal Environmental Research Letters, suggests that lemmings may be maintaining the biomass of certain plants in the Arctic at a time when the...

Taiga
2013-04-19 18:21:46

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

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, 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,...
