Bare in Arctic tundra reduces food truck business and slowly disappearing, according food truck bus


Bare in Arctic tundra reduces food truck business and slowly disappearing, according food truck business to a new study by researchers at the University of Texas at El Paso. In the northern part of the peninsula of Alaska food truck business (Cape Barrow) analyzed more than 2800 bar with the aid of historical photographs and satellite images food truck business between 1948 and 2010. In the period of 62 years, food truck business the researchers found that the number of bars in the region decreased by about 17%, while the size of the bar fell on average by one third. What tells us and how it affects wildlife in the area, read below.
Research conducted by Christian Andresen (postdoctoral research associate at the University of Texas) in collaboration with associate professor of biological sciences Vanessa Lougheed will be published in the Journal of Geophysical Research: Biogeosciences.
"17% is a very conservative estimate because we have not taken into account the ponds which are separated into two smaller ponds," explained Christian Andresen. "Some bars are elongated and to have decreased food truck business over time, can be divided into two or more smaller bar."
As one of the reasons for the disappearance of the pond, the research team said increase in temperature in the area, as well as the plants that grow there. The increase in temperature leads to melting of permafrost (frozen food truck business soil) that is rich in nutrients. These substances end up dissolving in the ponds, which causes increased growth of the plants.
"The plants have taken over the shallow ponds because they become warmer and richer in nutrients," said Andresen. "Before you know, the pond was already gone." Andresen is concerned that the geomorphology of the landscape food truck business in the region food truck business will change if these small bodies of water and still continue to decline.
"The role of the bar in the Arctic is extremely important," he said. "History tells us that the bars tended to increase during the hundreds of years, but ultimately became lakes. Ponds can shape the landscape over a long period, and no bar there will be no lakes in this region." food truck business
Bare peninsula Alaska around the Cape Barrow serve as a major source of food and habitat for nesting migratory birds, including waterfowl, which are on the endangered species list, such as Eider Somateria fischeri and Polysticta stelleri. If the water system continues to decline, it could disappear feeding and nesting grounds for this and many other migratory species. The impact of this on this kind would be disastrous.
