June: Ancient coral reefs | News and features

Pre-historic coral reefs dating back up to 250 million years extended much further away from the Earth’s equator than today, new research has revealed. The new study, published in Nature Communicationsdemonstrates how changes in temperature and plate tectonics, where the positions of Earth’s continents were in very different positions than today, have determined the distribution … Read more

Coral Reefs Generate a Hidden Sound Underwater, And It Could Help Us to Save Them

We tend to associate healthy coral reefs with their visual splendor: the vibrant array of colors and shapes that populate these beautiful underwater ecosystems. But they can also be rather noisy places. If you’ve ever been snorkeling in a coral reef environment, you’ll know the distinctive clicking and popping sounds made by various marine creatures … Read more

Dolphins keep their skin healthy with coral body scrubs

In the waters of the Red Sea off the coast of Egypt, bottlenose dolphins have a highly unusual relationship with their reef habitat. Divers frequently witness the marine mammals rubbing their faces and bodies against certain corals and sponges, even waiting in orderly lines to approach the invertebrates. “You get very excited to see that … Read more

“Traffic Calming” – Coral Reef Fish Breed More Successfully if Motorboat Noise Is Reduced

Spiny chromis family. Credit: Dr. Sophie Nedelec Coral reef fish breed more successfully if motorboat noise is reduced, new research shows. Scientists introduced “traffic calming” on three coral reefs for an entire breeding season – cutting the number of boats within 100 meters (328 feet), and reducing the speed of those within that distance. They … Read more

Majority of Great Barrier Reef coral studied in 2022 was bleached, Australian scientists say

CANBERRA, Australia (AP) – More than 90% of Great Barrier Reef coral surveyed this year was bleached in the fourth such mass event in seven years in the world’s largest coral reef ecosystem, Australian government scientists said. Bleaching is caused by global warming, but this is the reef’s first bleaching event during a La Niña … Read more

Scientists identify heat-resilient coral patches in Hawaii

Small patches of tropical reefs that endure despite punishing marine heat waves could hold clues to protecting the world’s corals, a new analysis suggests. Scientists took aerial surveys of Hawaiian reefs before and after a major heat wave in 2019, and found that corals at certain sites fared better than their neighbors. These so-called refuges … Read more

Findings could help manage and build a resilient network of coral reefs — ScienceDaily

As the world sees rising ocean temperatures, it will also see more cases of coral bleaching. When corals bleach, they become more vulnerable to other stressors such as water pollution. However, many reefs harbor corals that persist despite warming oceans. Unraveling the complex issue of coral bleaching and its impact on their survival or death … Read more

3D models of coral reefs are a crucial research tool – UB Now: News and views for UB faculty and staff

Research News Layered, 3D models of a small section of coral reef. Image: Ángela Martínez Quintana By CHARLOTTE HSU Coral reefs are complex ecosystems, a jumble of microhabitats created by corals and the substrate beneath them: holes, areas that are smooth or rough, regions with steep or shallow slopes. Where do coral larvae, called planulae, … Read more

Urgent Action Required To Protect World’s Coral Reefs From Disappearing Within 30 Years

Among the ecological communities studied are corals. An international team of environmental scientists has published a series of significant recommendations to protect, conserve and study the world’s coral reefs – the ‘canaries in the coal mine’ of climate change. The Vibrant Oceans Initiative presented their white paper on the future of the delicate and crucial … Read more

Video Shows Off a Squid’s Unexpected Camouflage Skill For The First Time

Octopuses and cuttlefish are the ultimate wallflowers. By changing the patterns and colors of their skin, these cephalopods can slip into the background of almost any seafloor scene. Squid, in comparison, are usually translucent or iridescent, but that doesn’t mean they don’t have a colorful trick or two up their eight sleeves. Recently, scientists in … Read more
