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

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

The Great Barrier Reef Is Suffering Another Mass Bleaching Event

Australia’s spectacular Great Barrier Reef is suffering “mass bleaching” as corals lose their color under the stress of warmer seas, authorities said Friday, in a widely blamed blow on climate change. The world’s largest coral reef system, stretching for more than 2,300 kilometers (1,400 miles) along the northeast coast of Australia, is showing the harmful … Read more

Fish Appear to Be Losing Their Color as Coral Reefs Decline, Scientists Warn

Fish communities on Australia’s famed Great Barrier Reef may become less colorful as oceans warm and corals bleach, according to a new Australian study that looked at changes in reef health, coral types, and resident fish over three decades. “Future reefs may not be the colorful ecosystems we recognize today,” wrote marine ecologist Chris Hemingson … Read more

Predators Have Evolved to Not Overexploit Their Resources. Can Humans Do The Same?

People have been trying to understand how predators and prey are able to stay balanced within our planet’s ecosystems for at least 2,400 years. The Greek author Herodotus even raised the question in his historical treatise Storieswritten around 430 BC. And when Charles Darwin published in 1859 his revolutionary theory of evolution in On the … Read more

“Taste” and “smell” of coral reefs provide insights into a dynamic ecosystem – BIOENGINEER.ORG

Coral reefs are hotspots of biodiversity and are amazingly productive with a vast number of organisms interacting simultaneously. Hundreds of molecules that are made by important members of the coral reef community were recently discovered by a team of scientists. Together, the compounds – modified amino acids, vitamins and steroids – comprise the “smell” or … Read more

Paris Agreement Climate Limits Still Catastrophic for Coral Reefs

Coral bleaching in Okinawa, Japan. Credit: Beger Lab Limiting global warming to 1.5 ° C above pre-industrial levels will still be catastrophic for coral reefs, new research suggests. Scientists led by the University of Leeds have discovered that more than 90% of tropical coral reefs will suffer frequent heat stress – their number one threat … Read more
