Even within a species, animals will suffer climate change differently. For sharks, it pays to live in warmer waters.
China's signature foreign policy is controversial for lots of reasons. But the environmental damage potentially wrought by the project has received scant attention.
A major war between the United States and Russia could make global fish catches fall by as much as 30 per cent.
Marine fish could serve as a crucial global emergency food supply in times of crisis, if marine ecosystems were in a healthy state to start with.
Maerl beds are the coral reefs of the British Isles. But like their tropical counterparts, they're threatened by climate change.
Sexual reproduction helps keep coral colonies diverse and resilient. Now, scientists are doing it in a lab to restock flagging reefs.
A rockfish hides in a red tree coral in the deep sea.
Here's how microplastics from your clothes end up in the deep sea.
The surprise decision is an important win for many Australians, but reform of Australia's offshore petroleum laws is urgently required to protect marine environments.

Scientists are building up a picture of how much carbon can be taken out of the atmosphere and stored in coastal ecosystems.
Some lakes in the Arctic are expanding and others are disappearing as permafrost thaws.
This lake north of Inuvik, N.W.T., is expanding as the ice wedges (darker lines leading away from the lake) around this lake melt and the ground subsides.
Hundreds of thousands of lakes, rivers and streams in the Arctic exist only because of the permafrost that lies beneath them. The warming Arctic threatens to change that.
A whale shark, the only fully protected shark species in Indonesia, swims under a fishing net.
Shark fisheries in Indonesia are an important economic resource in several areas. Hence, stronger regulations are needed to prevent declines in shark population.
Seagrass meadow in Wakatobi National Park, Indonesia. Seagrass is an important nursery for many juvenile reef fish.
Although less well known than its cousins, coral reefs and mangroves, seagrass plays a crucial role in climate change mitigation.
Destructive fishing, bombing and poisoning were banned in Indonesia in 2004 but enforcement is weak.
Our study found that some individuals who previously participated in destructive fishing practices can transform into inspiring leaders and influence others to protect coral reefs.

Populations of plankton are in decline. If we push this critical foundation of the marine food chain to extinction, we could cripple ecosystems for millions of years.
Sunset off the coast of Newfoundland.
Coastal communities are helping scientists understand the impacts of marine heatwaves — and find solutions.
Human-built structures are home to a wide variety of creatures.
When we build marinas, ports, jetties and coastal defences we introduce hard structures that weren’t there before, and which reduce the amount of sunlight hitting the water.
They swim, they eat, they multiply.
Marine parks are good for fish - especially if they’re in the right areas.
With strategic planning, the marine protected area network could be a third smaller, cost half as much, and still meet the international target of protecting 10% of every ecosystem.
Shark Bay was hit by a brutal marine heatwave in 2011.

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.
Nature’s bank vault.
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.
Sydney’s iconic beaches are not yet part of a marine park.
The New South Wales government has turned its back on plans to create sanctuary zones covering 2.4% of waters around Sydney, despite evidence that these 'no-take' areas are crucial for protecting fish.
