Coral reefs are disappearing at an unprecedented rate as climate change, marine heatwaves, pollution and coastal development threaten one of Earth's richest ecosystems. While scientific research has greatly advanced our understanding of the crisis and ways to restore damaged reefs, a new international paper argues that science alone will not be enough to protect them.

Writing in Science Advances, researchers from Bar-Ilan University and leading institutions around the world call for a fundamental shift in coral conservation by integrating science with art, design, culture and community engagement to inspire public awareness and meaningful action.

With an anticipated “super” El Niño looming, a new study led by UC San Diego’s Scripps Institution of Oceanography considers whether society could use a weather-altering technique as a tool to mitigate the floods, extreme heat and other events that El Niño would bring.

Researchers have traced the journey of a plastic bottle cap recovered near the waters of southern Japan by combining data from the label, chemical clues in tiny shells, and ocean current simulations. They found 307 organisms, including a polychaetae worm not found in Japanese waters before. The findings, published in Marine Pollution Bulletin, show that when species that significantly shape their environments (ecosystem engineers) colonize plastic debris, entire micro-communities can be transported over extended periods, with implications for invasive species risk and marine biodiversity conservation. 

A collaborative team of biologists led by the University of Massachusetts Amherst, MIT Sea Grant at the Massachusetts Institute of Technology and the Center for Coastal Studies has discovered that the invasive Manila clam, Ruditapes philippinarum, has established itself along the northwestern Atlantic coastline — the last place in the northern hemisphere to have remained Manila-clam free. The team’s findings, published in Biological Invasions, document an exceedingly rare moment when an invasive species first takes hold in a new environment and begins to spread.

Why do some coral reefs weather marine heatwaves better than others? A new study published in Scientific Reports shows that the answer may lie not only in local ocean conditions, but also in climate patterns that span entire ocean basins. By combining long-term ocean observations with chemical records preserved in coral skeletons, the researchers reveal how large-scale climate oscillations regulate the natural cooling that can help protect coral reefs during marine heatwaves. First author Dr. Hana Camelia and Dr. Thomas Felis from MARUM – Center for Marine Environmental Sciences at the University of Bremen lead the study.

Scientists from HSE University, MSU, and Tallinn University of Technology have studied a fossil species of ancient brachiopods that lived in a warm sea in what is now northern Estonia more than 445 million years ago. These ancient brachiopods developed a cup-shaped shell with a protective 'cap' that shielded them from overgrowth by other marine organisms. The study has been published in Palaeogeography, Palaeoclimatology, Palaeoecology.
