Nature's tiny engineers: Corals control their environment, stirring up water eddies to bring nutrients

Conventional wisdom has long held that corals -- whose calcium-carbonate skeletons form the foundation of coral reefs -- are passive organisms that rely entirely on ocean currents to deliver dissolved substances, such as nutrients and oxygen. Show More Summary

By: st lucia diving

Make sure you take a look at the under hangs and pockets in the coral reef. Scuba diving affords men and women with a possibility to see a few of Mother Nature's most magnificent sights. Most people like to go to observe the aquatic wildlife, which means that the water has to be relatively clear.

Want To Become A Coral Reef When You Die?

The subject of dying is one that we normally don't want to spend time thinking about, but if there is one thing for sure in this world it is that we are all going to die. What happens to our remains is up to us. Standard burials have been eating up the land to the point that the space could one day run out. Show More Summary

The BFI Announces the 2014 Semi-Finalists for the Buckminster Fuller Challenge

Algal Turf Scrubbing After spending years studying natural solar bio-energy in Caribbean coral reefs, Walter H. Adey, PhD. developed Algal Turf Scrubber, a biomimetic system that generates a fast-growing polyculture of locally adopted algae species atop

Diverse coral communities in mangrove habitats suggest a novel refuge from climate change

Risk analyses indicate that more than 90% of the world’s reefs will be threatened by climate change and local anthropogenic impacts by the year 2030 under “business-as-usual” climate scenarios. Increasing temperatures and solar radiation cause coral bleaching that has resulted in extensive coral mortality. Show More Summary

What the “Call of the Reef” is Telling Us

Coral reefs are in crisis. They are fragile. They are complex. And they are disappearing faster than we are able to understand them. This threat is exacerbated by an ecological battle raging on reef lines between corals and seaweeds. When fish are removed, seaweeds run rampant, and corals suffer. This negative feedback loop is often […]

Sickly Coral Reefs Fail the Smell Test

When looking for a place to settle down, these animals use chemical cues to avoid reefs that are littered with seaweed and flock to healthy habitats instead, according to a new study. Scientists have seen corals decline around the world over...Show More Summary

Fish and coral smell a bad neighborhood: Marine protected areas might not be enough to help overfished reefs recover

Pacific corals and fish can both smell a bad neighborhood, and use that ability to avoid settling in damaged reefs. Damaged coral reefs emit chemical cues that repulse young coral and fish, discouraging them from settling in the degraded habitat, according to new research. Show More Summary

Welcome to Google Street View, Indonesia

Google launched Street View in Indonesia on Thursday, allowing users to see panoramic cityscapes and underwater views of the country's striking coral reefs With a population of nearly 250 million, Indonesia is Google's biggest market in Asia thus far. Show More Summary

Marine protected areas might not be enough to help overfished reefs recover

The study for the first time tested coral larvae in a method that has been used previously to test fish, and found that young coral have strong preferences for odors from healthy reefs. "Not only are coral smelling good areas versusShow More Summary

Acid–base physiology response to ocean acidification of two ecologically and economically important holothuroids from contrasting habitats, Holothuria scabra and Holothuria parva

Sea cucumbers are dominant invertebrates in several ecosystems such as coral reefs, seagrass meadows and mangroves. As bioturbators, they have an important ecological role in making available calcium carbonate and nutrients to the rest of the community. However, due to their commercial value, they face overexploitation in the natural environment. On top of that, occurring […]

Falling ocean pH levels means rising threats for coral reefs

The rate of acidification in coral reef ecosystems is more than three times faster than in the open ocean, say a team of Southern Cross University biogeochemists. Led by recent graduate Dr Tyler Cyronak, the results highlight how coral reefs may be acidifying faster than expected. The University’s Centre for Coastal Biogeochemistry Research has published […]
