Protecting diversity on coral reefs: DNA may hold the key

Coral reefs are widely known for their stunning array of color, shape and forms of life, making them a model for extreme biodiversity. Hidden within the multitude of reef inhabitants, but no less important, is their genetic diversity— variability in DNA that gives species the capacity for adaptation, speciation and resilience in the face of stress. Research published on April 27 by a ...

In a study published today, researchers from the University of Hawai‘i at Mānoa, Rutgers University and the University of Haifa identified key and novel components of the molecular “toolkit” that allow corals to build their skeletons (called biomineralization) and described when—in the transformation from floating larvae to coral skeleton—these components are used. Corals are the sum of a symbiotic relationship between cnidarian animals and millions of ...

Microbial takeover on coral reefs?

Coral reefs—the world’s most productive and diverse marine ecosystems—rely on a masterful recycling program to stay healthy. The corals and algae that form the base of the reef’s food web release a variety of nutrients that support a complex and efficient food chain. But when this system gets out of whack, the cycle breaks down and endangers the coral reef’s ...

Heat trumps cold in the treatment of jellyfish stings


A recent study by researchers at the University of Hawaiʻi at Mānoa, published this month in the journal Toxins, may finally put to rest the ongoing debate about whether to use cold or heat to treat jellyfish stings. Their systematic and critical review provides overwhelming evidence that clinical outcomes from all kinds of jellyfish stings are improved following treatment with ...

New imaging technique reveals vulnerability of coral reefs

Corals, the primary reef builders on coral reefs, are often the star player in research studies addressing the impacts of climate change on coral reefs because they are the foundation of coral reef ecosystems. However, the breakdown of coral reefs from borers (such as bivalves, sponges, and marine worms) and grazers (such as parrotfish and urchins)—called bioerosion—and growth from encrusting ...

Piggybacking viruses

In the microscopic life that thrives around coral reefs, a team of researchers, including Katie Barott, postdoctoral researcher at the University of Hawaiʻi at Mānoa’s Hawaiʻi Institute of Marine Biology, have discovered an interplay between viruses and microbes that defies conventional wisdom. As the density of microbes rises in an ecosystem, the number of viruses infecting those microbes rises with ...
