Nature's tiny engineers
Date:9/1/2014

corals are completely dependent upon ambient flow, from tides and turbulence, to enable them to overcome diffusion limitation and facilitate the efficient supply of nutrients and the disposal of dissolved waste products," says Orr Shapiro, a postdoc from WIS and co-first author on the paper, who spent a year in Stocker's lab making these observations.

Under such a scenario, colonies in sheltered parts of a reef or at slack tide would see little water movement and might experience severe nutrient limitation or a buildup of toxic waste, to the point of jeopardizing their survival. "Even the shape of the coral can be problematic" under that passive scenario, says Vicente Fernandez, an MIT postdoc and co-first author of the paper. Coral structures are often "treelike, with a deeply branched structure that blocks a lot of the external flow, so the amount of new water going through to the center is very low."

The team's approach of looking at corals with video microscopy and advanced image analysis changed this paradigm. They showed that corals use their cilia to actively enhance the exchange of dissolved molecules, which allows them to maintain increased rates of photosynthesis and respiration even under near-zero ambient flow.

The researchers tested six different species of reef corals, demonstrating that all share the ability to induce complex turbulent flows around them. "While that doesn't yet prove that all reef corals do the same," Shapiro says, "it appears that most if not all have the cilia that create these flows. The retention of cilia through 400 million years of evolution suggests that reef corals derive a substantial evolutionary advantage" from these flows.

Corals need to stir it up

The reported findings transform the way we perceive the surface of reef corals; the existing view of a stagnant boundary layer has been replaced by one of a dynamic, actively stirred environment. This will be import
