14. Biodiversity, Food Webs, and Climate Resilience in Antarctica

Squid beaks can reveal an entire Antarctic food web. Marine ecologist Dr. José Xavier explains how researchers use squid beak identification and predator diets to trace the relationships connecting penguins, squid, krill, and other Antarctic wildlife. The conversation explores Southern Ocean biodiversity, the identification of ecological hotspots, and how climate change could alter the length and stability of Antarctic food webs. It also examines what scientists still do not know and why marine protected areas, sustainable fisheries, and long-term monitoring are essential for protecting these interconnected ocean ecosystems.
