The Strongest Arctic Fox Walks 3,500 Kilometers On Ice. 76 Days From Norway To Canada
According to the British "Guardian" reported on July 2, an Arctic fox walked more than 3,500 kilometers from Norway to Canada in just 76 days, which surprised the researchers of the Norwegian Polar Institute.
This animal, known as the Coastal Fox or Blue Fox, was installed in July 2017 with a tracking device. On March 26, 2018, it left the Spitsbergen archipelago in Svalbard, Norway. On April 16, 2018, after 21 days and 1512 kilometers of sea ice floes, it landed on Greenland. Its journey continues to Ellersmere Island in Canada, which arrived on July 1.
Eva Fuglei, a researcher who tracks the female fox, said: "We didn't believe it was true at first."
In a research paper titled "A Long Journey of a Female Fox Crossing the Frozen Sea," the institute said that the Arctic fox's journey was the longest in history. In fact, because the time was too long, the researchers initially wondered if the fox's collar could be removed and brought to a ship. "But no, no boat can go so far on the ice. So we have to keep up with the pace of the fox."
The collar transmits data every day for three hours. The fox travels through sea ice and glaciers, moving an average of 46.3 kilometers per day. When it was on the ice sheet north of Greenland, it moved an amazing 155 kilometers one day. "As far as we know, this is the fastest moving speed of the species in history," Vogel said in the paper.
The researchers believe that the ice covered on the ground that day may indicate that the fox used ice as a "vehicle." Foggley said: "Mountain fox will migrate in different areas, meet other species and seek food. Sea ice plays a key role in this process." He added that this is the first time they have recorded the animal in detail. Migration between the Arctic continent and ecosystems.
The fox's journey has raised concerns about how the impact of climate change on sea ice will affect animal migration.
Ola Elvestuen, Norwegian Minister of Climate and Environment, told the institute: “This is another example of the importance of sea ice to Arctic wildlife.” “The warming of the North is so fast. We are scared. It is necessary to reduce emissions quickly and prevent sea ice from disappearing throughout the summer."
The place where the fox was traced originally had the “marine food resources” on which it survived, including seabirds. It settled on Ellesmere Island, mainly feeding on lemmings, indicating its ability to change ecosystems.
Arctic fox is a very tenacious animal that can survive in the cold of minus 50 degrees Celsius. These animals have hairy feet, short ears and short noses to help them adapt to the cold climate.
