A catastrophic Failure of the hatching

Due to the progressive melting of ice in the Antarctic is the second largest Emperor penguin colony in the world has had in the past three years, virtually no breeding success. This is the alarming result of the study, the British Antarctic Survey (BAS), which was released on the international day for the penguins on Thursday. To Bay colony in the Halley, in the Weddell sea, up to 25'000 breeding pairs, therefore, are normally.

scientists have been using for a decade, high-resolution satellite images, the Size of the Halley-Bay-to analyze colony and other penguin colonies. On the basis of the density of the Population, leave your number estimate, explained BAS expert Peter Fretwell. 2016 unusually led to warm and stormy weather to fractures in the sea ice where Emperor penguins breed usually. In this breeding season, the satellites have survived pictures, almost none of the Chicks.

The Halley Bay in the Antarctic:

in 2017 and 2018, this repeated success. Over three years there had been "a catastrophic Failure of the hatching," said Fretwell. The colony of the Halley-had disappeared Bay "as well as" wrote the study authors. A penguin colony is grown in the vicinity. Many of the penguins from the Halley-sought Bay, and here's to safer nesting conditions.

BAS penguin expert Phil Trathan said it was unclear whether the breaking of the ice at Halley Bay due to climate change has been caused. "But such a complete failure in the Breed has been in this place, never been there."

Emperor penguins are the largest penguin species ever, they are up to 1.30 meters in size. You live around the South pole. In the face of global warming, their existence threatens to shrink until the end of this century, by up to 70 percent. In a study from the year 2015, it was recommended that Emperor penguins on the Red List of endangered species.

penguin-researcher Klemens Pütz said recently, of the 18 penguin species in the world, eleven are threatened with "more or less". The birds were very important to their respective Ecosystems. In addition, they are an "indicator species". "That is, if it's a penguin well in its environment, the Ecosystem is largely in order and every change immediately in the case of the penguins felt," explained puetz. (AFP)
