Scientists are worried, and there is the what : the Antarctic is facing an unexpected threat, that of the arrival of insects, and especially flies, which invade the white continent. An invasion which, in the long term, could affect the wildlife in Antarctica. The british daily The Guardian
says that the arrival of these insects, the more numerous, is due to the fact that the larvae are able to survive the new temperatures of the territory.
Global warming to the origin of this invasion ? Indeed, temperatures have increased 3 °C over the past three years on the continent, temperatures are high enough to allow the development of this insect. Like theArctic, the ice pack is reduced more on the southern continent, leaving many pieces of land, which allow for colonisation of insects, but also some plants, such as mosses.
Pathogens with devastating effects
This process is particularly visible on the peninsula region of the continent that is most vulnerable to global warming. “The housefly is a perfect example of the problem with which the Antarctic has to deal with it,” said the Guardian, Dominic Hodgson, the survey british Antarctic. “This insect between vessels, survives in the kitchens and develops on the continent. The fact of global warming, it now has a great chance of surviving longer in that territory, and it is a real concern, ” says the scientist.
And so the arrival of this insect disrupts the environment on the ” white continent “, it is mainly due to the fact that the pathogens that it carries could have a devastating effect on the species living there. In fact, three factors are at the origin of this invasion, explains the daily life : the regular visit of the scientists, the influx of mass tourists, and, of course, climate change.
According to the website Sea and Sea, the white continent, and more especially the peninsula, has hosted nearly 45 000 tourists during the winter of 2016-2017, said the association of tour operators of Antarctica. This represents an increase of 15 % compared to the previous season. For the winter of 2017-2018, a new increase of 5 % is anticipated. “These tourists are not paying attention, but when they set foot on the peninsula, they often report of the insects of other regions or of the mud on their shoes,” says Dominic Hodgson. To combat the invasion of these insects, the Guardian explained that measures would be put in place with the scientists. The tourists who travel on the continent will also be informed of the problem.
