Satellite images show how Antarctica’s vanishing sea ice is changing the food chain With the loss of sea ice, tiny filter feeders known as ‘salps’ can thrive, while shrimp-like krill lose out.

“Around ten years ago, everything changed.”

New satellite analysis shows Antarctic sea-ice loss has increased #phytoplankton across 70% of the #SouthernOcean. Good news? Not quite.

NEW RESEARCH 🚨

Researchers identify ultrasonography as reliable method of determining sex in migrating silver eels. This technique was shown to be more reliable than molecular marking, and removes the need for sacrifice.
