As the oceans warm, fish are moving to stay in temperature zones where they have evolved to live. This is helping some species, hurting others and causing a net reduction in potential catch.
Food safety is in the news again, this tiime after reported deaths from listeria after eating smoked salmon. Here's what we know so far and what you can do to cut your chance of getting sick.
Sending autonomous vehicles to the Southern Ocean can be fraught with anxiety, especially if one of them doesn't make radio contact when it's supposed to.
Scientists are predicting major algae blooms in Lake Erie and large dead zones in the Chesapeake Bay and Gulf of Mexico this summer. Nutrient pollution from industrial corn farming is a major driver.
New Zealand has one of the world's largest ocean territories, but the marine environment is at risk from climate change, pollution and fishing.
The endangered Hector's dolphins are found only in coastal seas in New Zealand, but conservation experts describe New Zealand's proposed protection plan for the marine mammals as misleading.
Fish farming has been criticised for a lack of sustainability – here's what has been changing and what still remains a challenge.
West Coast fisheries policy leaves the door open to speculative investors who see opportunity and can snap up fishing licences and quotas.
North Atlantic right whales are headed toward a traumatic extinction, but could rebound if humans can get out of their way.
To ensure overall biodiversity, the intensity and impact of small-scale fisheries' methods needs far more attention.
Thousands of hydropower dams are under construction around the world. New research shows that by cutting off sediment flow, these dams can have big ecological effects on far-off bays and deltas.
For decades, New England students took field trips out into the Long Island Sound. Their data show how quickly the sound is warming, leading to fewer American lobster, rock crab and winter flounder.
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.
Our new paper titled ‘DNA barcoding validates species labelling of certified seafood’ presents the largest and most comprehensive assessment of MSC-labelled products to date.
Kenya needs a national strategic environmental assessment which focuses on the use of sand for large scale construction.
With proper regulation, Lake Victoria's fisheries could increase production without damaging wild stocks or the environment.
Lake Malawi is considered a biodiversity treasure because almost all its species occurs nowhere else on the planet.
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.
Mangrove forests along the world's tropical and subtropical coasts store enormous quantities of 'blue' carbon – especially in river delta zones, where soil builds up quickly.
Without an array of ecosystems and species, it's tough for farmers to grow crops or ranchers to raise animals.
