The climate is getting warmer, and sea levels are rising--a threat to island nations. As a group of researchers led by colleagues from the University of Bonn found out, at the same time, tiny single-cell organisms are spreading rapidly through the world's oceans, where they might be able to mitigate the consequences of climate change. Foraminifera of the variety Amphistegina are stabilizing coastlines and reefs with their calcareous shells.
Countless billions of tiny, microscopic shelled creatures known as foraminifera inhabit the oceans of our planet: some of which look like little stars, others like Swiss cheese, and yet others like tiny mussels. They are extremely plentiful and exceptionally diverse in shape. Most of the approximately 10,000 foraminifera species live on the bottom of tropical and sub-tropical oceans, are surrounded by a calcareous shell, and do not even reach the size of a grain of sand. And yet, these tiny organisms are capable of enormous tasks.
