The wonder world of seagrass meadows Climate saviour, nursery, coastal protection

Seagrass not only stores the largest sugar reserves on our planet - this plant protects beaches worldwide from erosion and, with its almost 80,000-year-old seagrass meadows, is perhaps the oldest living thing on earth. Seagrass meadows are nurseries and habitats for countless species; they clean the seawater like a gigantic sewage treatment plant. With these superpowers, seagrass can help to slow down global warming. The documentary accompanies leading seagrass researchers from the Mediterranean to the Baltic Sea.

Our contribution from minute 13

The superworm - "no mouth, no bum and still happy"

An inconspicuous worm has unexpected abilities. It is an energetic perpetual motion machine that neither eats nor digests. It survives where hardly any life form survives permanently: in an underwater sand desert. It can change its sex or even adopt two sexes if it cannot find a mate or finds the wrong one. If it is split up, its remains live on. This is how the superworm was able to spread worldwide.

Our seagrass research in MaxPlanckResearch

Land of plenty in the Mediterranean


At the Max Planck Institute for Marine Microbiology in Bremen, Marcel Kuypers' and Nicole Dubilier's departments are unraveling the mysteries of seagrass meadows. With astonishing discoveries: Not only on land, but also in the sea, microorganisms play a crucial role in the fitness, productivity and material flows of plants.

These are the opening words of a comprehensive article in the Max Planck Society's science magazine MaxPlanckResearch, presenting our diverse research on seagrasses. It deals with their role in the large elemental cycles of nitrogen and carbon as well as with their bacterial subtenants and what that has to do with soft drinks. A worthwhile read!


Here you can find the article as e-paper and pdf. You can also order the magazine from the Max Planck Society.

A natural CO2-sink thanks to symbiotic bacteria

Like many land plants, seagrasses live in symbiosis with nitrogen-fixing bacteria

Seagrasses cover large swathes of shallow coastal seas, where they provide a vital habitat. They also remove large amounts of carbon dioxide (CO2) ...

Dead or alive: Seagrasses continue to release methane after their die-off

Methane is formed and released from seagrass meadows, even decades after the plants died off.

Seagrass meadows play an important role in the marine carbon cycle and our climate. On the one hand, they sequester carbon dioxide from the atmosph...

Sweet spots in the sea: Mountains of sugar under seagrass meadows

Seagrass meadows are underwater oases. Now researchers have discovered vast amounts of sugars underneath seagrass meadows. This sheds new light on how plants store carbon in the ocean.

Scientists from the Max Planck Institute for Marine Microbiology now report that seagrasses release large amounts of sugar, largely in the form of ...
