A new study from North Carolina State University reveals that the soundscapes of coral reef ecosystems can recover quickly from severe weather events such as hurricanes. The work also demonstrates that non-invasive monitoring is an important tool in shedding further light on these key ecosystems.
Communities living close to hard-bottomed shallow shores are more likely to hand-catch marine animals during seasons when other types of fishing often aren’t possible, a new study shows. The findings suggest that worsening sea conditions due to climate change will increase the importance of this ...
A simple but powerful idea is to improve the health of corals using cocktails of beneficial bacteria. The strategy is being explored as part of global scientific efforts to help corals become stronger, more stress resistant and more likely to survive bleaching events associated with climate change.
Coral within the family Acropora are fast growers and thus important for reef growth, island formation, and coastal protection but, due to global environmental pressures, are in decline
There are many fishes in the sea, they say. So, that means that it is also full of fish poop that is full of carbon. A study estimates that up to 16% of all the carbon in the world's ocean comes from fish poop, fish breath, and other excretions coming from fish.
It was a memorable finale to a day out on the Atlantic: a four-metre whale calf gliding past the boat as the divers returned to the Spanish island of El Hierro in the Canaries. Their incredible luck, however, would be made clear hours later, as researchers around the world clamoured for more det ...

The whole world has been overwhelmed by the urgent challenges brought by the COVID-19 pandemic. But while this crisis is preoccupying the world, there are graver long-t ...
An EPFL scientist has made a major breakthrough in the understanding of coral bleaching – a process that causes corals to lose their color and eventually leads to their death. The process is triggered by warmer ocean temperatures, and, according to the study, it begins much earlier than previous ...
Just as forests are called as the ‘lungs of the earth’, wetlands are the ‘kidneys’ that regulate water and filter waste from the landscape. The kidney comparison aside, wetlands are the primary sources of freshwater, buffers of floods and droughts, recycler of nutrients and chemicals, and inextr ...
A quarter of the carbon emissions that are warming the Earth dissolve into oceans, making them more acidic. Carbon emissions and warming are also causing ocean heat waves, which in turn is bleaching the world's coral reefs.
How the larvae of colorful clownfish that live among coral reefs in the Philippines are dispersed varies widely, depending on the year and seasons—a Rutgers-led finding that could help scientists improve conservation of species.
A more acidic ocean could give some species a glow-up. As the pH of the ocean decreases as a result of climate change, some bioluminescent organisms might get brighter, while others see their lights dim, scientists report January 2 at the virtual annual meeting of the Society for Integrative and ...
