Floodwater carries dense clouds of sediment, choking the lush seagrass meadows on which these gentle grazers rely.
A single seagrass plant in Shark Bay is around 4,500 years old, covers 200 square kilometres of seabed, and thrives in harsh conditions.
Seagrass meadows are a powerful ally in the effort to slow climate change and reverse wildlife losses.
China’s signature foreign policy is controversial for lots of reasons. But the environmental damage potentially wrought by the project has received scant attention.
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.
Oxygen produced by these plants helps animals boost their metabolism to match the heat.
Seagrass may look unassuming, but healthy oceans depend on the huge meadows that grow in temperate and tropical waters.
Far more megafauna species use coastal wetlands than we thought. And it affects the way we need to address the extinction crisis.
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.
