Penguin poop seen from space is revealing how Antarctica's food web has quietly changed over the past 30 years as warming seas alter what penguins eat
Antarctic penguin colonies are showing dietary shifts, according to new satellite data. Researchers analysed guano stains to track penguin food sources over decades. Warming seas have caused a significant loss of sea ice in certain regions. This change forces penguins to rely more on krill instead of fish. These observations signal broader changes within the Antarctic marine ecosystem.
