The world's salty, tidal marshes are hotspots of carbon storage and productivity, building up sediments and plant material to stay above sea level. However, as sea level rises at an increasing rate, scientists debate whether it's possible for wetlands to win the race. New research reveals how salt marshes along the U.S. East Coast have responded to accelerating sea level rise by building elevation more quickly to keep pace with the sea over the last century.

The diet quality of fish across large parts of the world's oceans could decline by up to 10 per cent as climate change impacts an integral part of marine food chains, a major study has found.

The first study into the biological response of the upper ocean in the wake of South Pacific cyclones could help predict the impact of warming ocean temperatures, researchers believe.

An unusually severe form of toxoplasmosis killed four sea otters and could pose a threat to other marine wildlife and humans, finds a new study.

Samples from the asteroid Ryugu collected by the Hayabusa2 mission contain nitrogenous organic compounds, including the nucleobase uracil, which is a part of RNA.

Fewer parasites in U.S. waters might be seen by many as a good thing, but a biologist says the trend signals potential danger for fish and other wildlife.

Future ocean warming and marine heatwaves could impact the growth and development of clownfish during their earliest life stages, suggests a new study.

Researchers confirmed what was already known: jellyfish eat bigger prey as they grow, which means they also occupy a higher position in the food web as they grow. They also found that some of the concentrations of 'healthy fats,' increase as jellyfish grow. These changes might be influenced by their diet, and as they feed on bigger prey with higher levels of fatty acids, the jellyfish accumulate more of these fatty acids.

The small size and isolation of the endangered population of Southern Resident killer whales in the Pacific Northwest have led to high levels of inbreeding. This inbreeding has contributed to their decline, which has continued as surrounding killer whale populations expand, according to new research.

New research is beginning to unravel the times of year and locations where whales are at greatest danger of entanglement in fishing gear on the Oregon Coast.

A new study is providing an unprecedented examination of oxygen loss on coral reefs around the globe under ocean warming. The study captures the current state of hypoxia -- or low oxygen levels -- at 32 different sites, and reveals that hypoxia is already pervasive on many reefs.

Intense fishing and over-exploitation have led to evolutionary changes in fish stocks like cod, reducing both their productivity and value on the market. These changes can be reversed by more sustainable and far-sighted fisheries management. A new study shows that reversal of evolutionary change would only slightly reduce the profit of fishing, but would help regain and conserve natural genetic diversity.

The Notre-Dame de Paris is the first known cathedral of Gothic-style architecture to be initially constructed with extensive use of iron to bind stones together. The 2019 fire that significantly damaged the cathedral enabled analyses leading to this discovery.

Researchers have found that an outbreak of highly pathogenic avian influenza (HPAI) was associated with the deaths of more than 330 New England harbor and gray seals along the North Atlantic coast in June and July 2022, and the outbreak was connected to a wave of avian influenza in birds in the region.

A new study has found evidence of cheesemaking, using milk from multiple animals in Late Neolithic Poland.

Dramatic differences between shallow and mesophotic reefs stress the importance of studying--and conserving--these vital ecosystems along their entire depth gradient.

A new study of Antarctic minke whales reveals a minimum size limit for whales employing the highly efficient 'lunge-feeding' strategy that enabled the blue whale to become the largest animal on Earth.

An international team of experts convened remotely as part of the Deep Ocean Stewardship Initiative's Climate Working Group to consider the deep-sea impacts of ocean-based climate intervention (OBCI). A research team has analyzed the proposed approaches to assess their potential impacts on deep-sea ecosystems and biodiversity. Their findings raise substantial concern on the potential impacts of these technologies on deep-sea ecosystems and call for the need for an integrated research effort to carefully assess the cost and benefits of each intervention.

A global dataset of ocean plastic pollution between 1979 and 2019 reveals a rapid and unprecedented increase in ocean plastics since 2005, according to a new study.
