Rethinking the reef
Date:7/3/2014

A new study by biologists at San Diego State University and Scripps Institution of Oceanography shows that inhabited coral islands that engage in commercial fishing dramatically alter their nearby reef ecosystems, disturbing the microbes, corals, algae and fish that call the reef home.

The study's lead author, Linda Wegley Kelly, is a postdoctoral scholar in the lab of SDSU virologist Forest Rohwer.

For the study, she looked at seawater samples collected from the surfaces of reefs surrounding all 11 of the Line Islands, a chain of atolls in the central Pacific Ocean. Over the past five years, Kelly and her colleagues have made sporadic trips to the islands, collecting the samples with a specially adapted bilge pump that sucks up approximately 100 liters of water in a given area.

Kelly sequenced the microbiomes of the samples to determine the DNA encoded by the viruses, bacteria, archaea (tiny, single-celled microorganisms like Halobacteria), and protists (similarly tiny eukaryotic microorganisms such as diatoms) all living in the same space. Within these millions of DNA sequences, Kelly found that certain types of bacteria predicted whether the reef was predominantly composed up of coral or algae.

Algae or coral?

The preponderance of either of these organisms has huge ramifications for the health of the surrounding sea.

"Corals are fierce competitors for space on the reef," Kelly said. "In a healthy marine environment, reefs support a vibrant population of corals and other calcifying organisms that continuously build the reef skyward."

If reefs are dominated by algae, however, the entire habitat dissolves over time and the fish don't have anywhere to go, Kelly explained.

When she sequenced the surfaces of algae-covered reefs, Kelly identified microbes that may contribute to an ecological feedback loop which impairs coral growth. Her study was published this week in the
