Berlin, August 5
British scientists say there are extra emperor penguin colonies in Antarctica than beforehand thought primarily based on proof of chook droppings noticed from area.
A research revealed on Wednesday by scientists on the British Antarctic Survey counted 61 emperor penguin colonies dotted across the southernmost continent, 11 greater than the quantity beforehand confirmed.
Scientists used photographs from Europe’s Sentinel-2 satellite tv for pc mission to search for smudges on the ice that indicated massive quantities of guano, or penguin poop.
The majestic emperor penguin breeds in distant areas the place temperatures can drop as little as minus 50 levels Celsius (minus 58 levels Fahrenheit).
Researchers have lengthy relied on aerial pictures and satellites to identify colonies of the flightless marine birds.
Peter Fretwell, a British Antarctic Survey geographer and the research’s lead creator, known as the newest depend “good news” however famous that the newly noticed colonies have been small.
“(They) solely take the general inhabitants depend up by 5-10 per cent to only over half 1,000,000 penguins or round 265,500 – 278,500 breeding pairs,” he stated.
Emperor penguins are weak to the lack of sea ice predicted to happen due to man-made international warming. Some researchers recommend the variety of colonies may drop by greater than 30 per cent by the top of the century.
Some of the newly found colonies are situated far offshore, on sea ice that has shaped round grounded icebergs and which is especially prone to disappearing. AP
