Increase in penguin populations during the Little Ice Age in the Ross Sea, Antarctica
Penguins are an important seabird species in Antarctica and are sensitive to climate and environmental changes. Previous studies indicated that penguin populations increased when the climate became warmer and decreased when it became colder in the maritime Antarctic. Here we determined organic marke...
