KAUST inaugurates the world’s first Coral Probiotics Village

King Abdullah University of Science and Technology (KAUST) recently announced the inauguration of the world's first coral probiotics village in the Red Sea. The village, located around 20 km off the campus shores, is part of the University's Red Sea Research Center (RSRC) efforts and approach to coral preservation and restoration. The inaugural featured an underwater ribbon-cutting ceremony and was attended by representatives from KAUST leadership, RSRC researchers and students, as well as members from the community.

Restoring coral health

Coral reef ecosystems are severely threatened by climate change. The urgent need to address the issue is driving a new era of innovation in reef science, shown by a global multidisciplinary exploration of different approaches to enhance coral resilience.

An international team including KAUST professors Manuel Aranda and Raquel Peixoto, with adjunct professor Chris Voolstra, have proposed an adaptive framework to increase the resilience of corals in the face of climate change.

KAUST scientists propose a nature-based adaptive approach to boost coral restoration

Coral reefs are rapidly degrading all over the world due to climate change and human activity. This phenomenon has dire consequences on the livelihoods of almost one billion people who directly depend on the ecosystem services delivered through healthy tropical reefs. Based on current projections, and without active intervention, coral reefs may become extinct by the year 2050.

Finding Bright Spots in the Global Coral Reef Catastrophe

The first-ever report on the world’s coral reefs presents a grim picture, as losses mount due to global warming. But there are signs of hope — some regions are having coral growth, and researchers found that corals can recover if given a decade of reprieve from hot water.

Probiotics for corals boost resilience, help prevent mortality

As more coral reefs around the world suffer from bleaching and mass mortality due to warming ocean temperatures and related climate change conditions, good news about reefs is welcome news.

Corals survive the heat with bacterial help

Treating corals with a probiotic cocktail of beneficial bacteria increases survival after a bleaching event, according to new research. This approach could be administered in advance of a predicted heatwave to help corals recover from high sea temperatures.

Climate change is increasing the temperatures of the oceans, which disrupts the relationship between corals and their symbiotic photosynthetic algae and causes corals to bleach, in some cases eventually leading to their death. KAUST researchers have proposed that manipulating the coral microbiome might enhance their stress tolerance by using beneficial microorganisms for corals, or BMC.

A radical plan to save ravaged coral reefs—with customized medicine

For decades, scientists have been engaged in a furious effort to save the world’s coral reefs, which are vanishing at an alarming rate—about half of them are believed to have died over the last 50 years. Efforts to “do something about it” have ranged from replanting programs to genetic engineering and establishing protective reserves. The combined effects of acidification, pollution, and climate change, however, continue to ravage these colonies. Scientists predict that up to 9O percent will die out over the next two decades, and that they will be gone completely by 2100.

Professor Raquel S. Peixoto: The Coral Warrior

The world’s coral reefs are in crisis, with climate change emerging as the biggest threat of mass coral reef bleaching. Coral reef health walks hand-in-hand with overall ocean health, in addition to supplying effective shoreline protection and supporting businesses globally, from fishing to tourism.

Will Probiotics Save Corals or Harm Them?

Manta rays and whitetip reef sharks glide past socially distanced visitors at Rio de Janeiro’s hangar-sized AquaRio aquarium. In a laboratory upstairs, above the main gallery, a new experiment is underway, one that marine scientists hope will enhance the survival prospects of the world’s coral reefs. Twenty rectangular aquarium tanks, each about 20 centimeters wide, are arranged in a grid on the fourth floor. Each one houses a colorful assortment of coral fragments.

Working towards a safer future for our oceans

The ocean’s stable health is an important component that upholds the climate’s behavior and life on Earth. A key indicator of that health? Coral reefs, also known as the marine "canaries in the coal mine."

Coral bleaching due to climate change is a major concern among ocean researchers. Record ocean temperatures during 2014-2017 triggered a mass bleaching event around the globe, a sign that this issue is becoming more dire.

Microbiome boost may help corals resist bleaching

A simple but powerful idea is to improve the health of corals using cocktails of beneficial bacteria. The strategy is being explored as part of global scientific efforts to help corals become stronger, more stress resistant and more likely to survive bleaching events associated with climate change. Corals rely on bacterial and algal symbionts to provide nutrients, energy (through photosynthesis), toxin regulation and protection against pathogenic attacks.
