After a bad winter in the ocean, female Magellanic penguins suffer most, study shows

A view of South America from space.

Researchers from the University of Washington have shown how Magellanic penguins fare during the winter months when they spend months at sea feeding. They have discovered that oceanographic features are more likely to negatively impact the body conditions of Magellanic penguin females, but not males, when the penguins return to their nesting grounds in spring.

trawling boat

A new analysis that uses high-resolution data for 24 ocean regions in Africa, Europe, North and South America and Australasia shows that 14 percent of the overall seafloor shallower than 1,000 meters (3,280 feet) is trawled. The paper shows that the footprint of bottom-trawl fishing on continental shelves and slopes across the world’s oceans often has been substantially overestimated.
