Arctic Ecosystem Changes and Research

The video follows Andri Salah on a National Geographic expedition to the Russian Arctic, focusing on the seabirds of France Joseph Land. It highlights the little auks, which are adapting to environmental changes due to reduced sea ice. A study reveals a 4% decrease in their body mass, possibly linked to changes in plankton caused by climate change. The research finds that warm-water plankton, which provide less energy, are moving north, potentially affecting the little auks' diet. The video underscores the need for further research to understand the Arctic's changing ecosystem.
