Two recent massive breeding failures in an Adélie penguin colony call for the creation of a marine protected area in D'Urville Sea/Mertz
In the d'Urville Sea in East Antarctica, a population of roughly 20,000 pairs of Adélie penguins of Iles des Pétrels (Terre Adélie) has experienced two massive breeding failures, with no chick surviving the 2013-14 and 2016-17 breeding seasons. In both seasons the extent of sea ice in front of...
