Healthy seagrasses form underwater meadows teeming with fish and shellfish. A successful large-scale restoration project in Virginia could become a model for reseeding damaged seagrass beds worldwide.
Marine wildlife rarely remain in one habitat. Most species rely on a healthy network of ecosystems to raise their young and catch their food.
Between 1986 and 2016, Kenya lost about 21 of its seagrasses.
Although less well known than its cousins, coral reefs and mangroves, seagrass plays a crucial role in climate change mitigation.
Spiny lobsters with deadly PaV1 virus are found in seagrass habitats more than any other - but the seagrass may actually be helping to combat the disease.
In a world-first, scientists have counted the greenhouse gas absorbed and emitted by Australia's mangroves, seagrass and other ocean ecosystems.
Seagrass may look unassuming, but healthy oceans depend on the huge meadows that grow in temperate and tropical waters.
George Monbiot talks with an ecologist about natural solutions to the climate crisis.
Marine heatwaves, like their land counterparts, are growing hotter and longer. Sea species in southeastern Australia, southeast Asia, northwestern Africa, Europe and eastern Canada are most at risk.
Everyone knows the Great Barrier Reef is in peril. But a continent away, Western Australia's Shark Bay is also threatened by marine heatwaves that could alter this World Heritage ecosystem forever.
Coral reefs are in trouble, but other marine species are also feeling the strain but are off the conservation radar.
The sediments that accumulate beneath seagrass meadows can act as secure vaults for shipwrecks and other precious artefacts, by stopping water and oxygen from damaging the delicate timbers.
New research highlights the role of sea turtles and dugong in the dispersal of seeds and maintenance of seagrass meadows, an important marine habitat and the primary food source for both animals.
Seagrass meadows play a significant role in supporting world fishery productivity.
The 'canaries of the sea' are sending a worrying message about the health of our oceans.
It can fill in the scientific gaps.
Seagrass medows support rich biodiversity. New research shows what you can do to protect them.
Trowels and spades are being put to use in the sea.
It's not just the land and people that have been badly affected by hurricanes.
Scientists have sequenced the seahorse's genome and found the genes that could explain male pregnancy.
