arctic ecosystem

ecosystems → arctic tundra

occurs in the far Northern Hemisphere, north of the taiga belt. The word “tundra” usually refers only to the areas where the subsoil is permafrost, or permanently frozen soil. Permafrost tundra includes vast areas of northern Russia and Canada. Arctic tundra contains areas of stark landscape and is frozen for much of the year.

The arctic is perhaps the most vulnerable ecosystem in the wake of climate change. According to the ACIA, a report by the Arctic Council, average temperatures have risen almost twice as fast in the arctic as compared to the rest of the world since the industrial revolution. The arctic ecosystems are especially threatened by climate change compared to warmer systems because in general, there are fewer species to fill similar roles(vegetation, prey, predator, scavenger) so when one species is in decline or displaced, there is a rapid and devastating ripple effect across the entire system.

Disappearing sea ice has put Arctic ecosystem under threat

In a few days the Arctic’s beleaguered sea ice cover is likely to set another grim record. Its coverage is on course to be the lowest winter maximum extent ever observed since satellite records began. These show that more than 2 million square kilometres of midwinter sea ice have disappeared from the Arctic in less than 40 years.

The ice’s disappearance – triggered by global warming caused by rising carbon emissions from cars and factories – is likely to have profound implications for the planet. A loss of sea ice means a loss of reflectivity of solar rays and further rises in global temperatures, warn researchers.

Canadian physician takes Wildlife Photographer of the Year 2015 title

Canadian amateur photographer Don Gutoski was named Wildlife Photographer of the Year 2015 by a panel of international judges for his image Tale of two foxes, a beautiful but haunting portrait of the struggle for life in the subarctic climes of Cape Churchill, Canada.  

Jury member and National Geographic magazine’s senior editor for natural history projects, Kathy Moran says, “The immediate impact of this photograph is that it appears as if the red fox is slipping out of its winter coat. What might simply be a straightforward interaction between predator and prey struck the jury as a stark example of climate change, with red foxes encroaching on Arctic fox territory. This image works on multiple levels: it is graphic, it captures behaviour and it is one of the strongest single storytelling photographs I have seen.”                             

Beating more than 42,000 entries submitted from across 96 countries, Don’s image will take centre stage at the fifty-first Wildlife Photographer of the Year exhibition, opening at the Natural History Museum on 16 October.
