Why should we try to protect the coral reefs?

Repeat coral bleaching caused by rising sea temperatures has resulted in lasting changes to fish communities, according to a new long-term study in the Seychelles.

Study shows severe loss of central Indian Ocean coral reefs between 2015 and 2017.

Study shows dramatic loss of central Indian Ocean coral reefs between 2015 and 2017.

A new study from The Australian National University (ANU) has shown the impact phosphate mining is having on our coral reefs.

More than 80 marine scientists join together to identify key social-environmental pressures and human impacts on coral reefs The authors recommend "protect, recover, and transform" strategies to save and protect coral reefs More than 2,500 reef systems across 44 countries were analyzed

Australia's Other Great (and Threatened) Coral Reefs.

Marine scientists are using portable ship-borne aquaria in the search for heat-resistant corals that could survive warming ocean temperatures caused by climate change.

Simulations reveal unexpected connections in the Red Sea basin that could help marine conservation.

Competitive interactions between corals and macroalgae play an important role in determining benthic community structure on coral reefs. While it is known that macroalgae may negatively affect corals, the relative influence of contact- versus water-mediated macroalgal interactions on corals - such as via an influence on coral-associated microbiomes - is less well understood. Further, the impacts of macroalgae on corals that have persisted in a heavily urbanized reef system have not been explored previously. We examined the effects of the macroalgae Lobophora sp. and Hypnea pannosa on the physiology and microbiome of three Indo-Pacific coral species (Merulina ampliata, Montipora stellata, and Pocillopora acuta) collected from two reefs in Singapore (Pulau Satumu and Kusu Island), and compared how these effects varied between direct contact and water-mediated interactions. Direct contact by Lobophora sp. caused visible tissue bleaching and reduced maximum quantum yield (Fv/Fm) in all three coral species, while direct contact by H. pannosa only led to slight, but significant, suppression of Fv/Fm. No detrimental effects on coral physiology were observed when corals were in close proximity to the macroalgae or when in direct contact with algal mimics. However, both direct contact and water-mediated interactions with Lobophora sp. and H. pannosa altered the prokaryotic community structures in M. stellata. For M. ampliata and P. acuta, the changes in their microbiomes in response to algal treatments were more strongly influenced by the source reefs from which the coral colonies were collected. In particular, coral colonies collected from Kusu Island had proportionately more initial abundances of potentially pathogenic bacteria in their microbiomes than those collected from Pulau Satumu; nevertheless, coral fragments from Kusu Island had the same physiological responses to macroalgal interactions as corals from Pulau Satumu. Overall, our results reveal that, for the sp

Battling drugs and commercial fishing boats, Myanmar's 'sea gypsies' struggle to make a living.

- Scientists identify climate-resistant coral refuge in northern Mozambique - Refuge could preserve climate-sensitive corals due to environmental gradients that allow for coral acclimatization - Overfishing may soon jeopardize refuge - Scientists say area fisheries should be better managed to protect reefs - Study appears in journal Ecosphere

Reconstructed temperatures provide information about systematic errors in ship measurements.

Tough species of corals can go mobile and lay the foundations for new reefs in otherwise inhospitable areas, a study shows.

Today, the Khaled BIN SULTAN Living Oceans Foundation published our findings on the state of coral reefs in the Chagos Archipelago. This research mission gave us the chance to study some of the most isolated and well-protected coral reefs in the world. Our research, based on thousands of scientific surveys, found reefs in the Chagos Archipelago were some of the most diverse and had a higher density of fish than all of the reefs studied on the Global Reef Expedition, the largest coral reef survey and mapping expedition in history.

Coral insights into 1,000 years of seasonal changes in the Arabian Sea warn of significant impacts caused by global warming.
