Технологии спутникового картографирования помогли ученым найти 11 ранее скрытых колоний императорских пингвинов. Об этом пишет Metro.

Таким образом предполагаемая популяция этих пингвинов выросла на 5-10 процентов и должна составлять более полумиллиона особей. Такая надбавка явно не помешает птицам, которые, фактически, находятся в авангарде видов, которым угрожает глобальные изменение климата Земли.

Пингвины размножаются на морском льде, которого с каждым годом становится все меньше из-за увлечения средних температур. Несмотря на открытие новых мест обитания и размножения, императорские пингвины все равно остаются в зоне риска. Ученые называют их «канарейками в шахте», имея в виду, что по состоянию популяции пингвинов можно будет фиксировать общие тенденции и масштабы изменений климата.

Императорские пингвины — крупнейшие пингвины в мире, они могут весить до 40 килограмм и жить до 20 лет. Яйца высиживает самец. Они привыкли жить и плодиться в суровых зимних условиях, которые являются для них вполне комфортными.

EMBARGOED FOR RELEASE: 4-AUG-2020 19:15 ET (4-AUG-2020 23:15 GMT/UTC) A new study using satellite mapping technology reveals there are nearly 20% more emperor penguin colonies in Antarctica than was previously thought. The results provide an important benchmark for monitoring the impact of environmental change on the population of this iconic bird. See SWNS story SWNNpenguins. Reporting this week in the journal Remote Sensing in Ecology and Conservation, the authors describe how they used images from the European Commission's Copernicus Sentinel-2 satellite mission to locate the birds. They found 11 new colonies, three of which were previously identified but never confirmed. That takes the global census to 61 colonies around the continent. Emperor penguins need sea ice to breed and are located in areas that are very difficult to study because they are remote and often inaccessible with temperatures as low as ?50?C (?58 degrees Fahrenheit). For the last 10 years, British Antarctic Survey (BAS) scientists have been looking for new colonies by searching for their guano stains on the ice.
