The Southern Ocean circling Antarctica is one of Earth's richest marine ecosystems. Its food webs support an abundance of life, from tiny micro-organ ...

At Steinberg’s lab, researchers are examining how warming oceans — Antarctic krill need water colder than 4 degrees Celsius (39 Fahrenheit) to survive — are altering krill’s life cycle.

Krill has a complex, regimented life cycle that requires a delicate ... Both Piñones and Kawaguchi say that a lot more research needs to be done to better understand the future of Antarctic krill.

The krill life cycle is synchronised with the Southern Ocean’s dramatic seasonal cycles. Typically this allows krill to both maximise growth and reproduction and store reserves to survive the ...
